Tool Definition Quality
Average 3.2/5 across 168 of 193 tools scored. Lowest: 1.7/5.
Every tool has a clear, distinct purpose with thorough descriptions. Even closely related tools like base64_decode/encode and hash_md5/sha256 are easily differentiated by name and description.
All tools follow a consistent lowercase_underscore naming convention, typically in a <domain>_<action> or <action>_<domain> pattern. There are no jarring deviations or mixed styles.
193 tools is an extreme count, far beyond what any focused server needs. While each tool has utility, the sheer number creates a kitchen-sink effect that overwhelms agents and hinders discoverability.
Within each subdomain (JSON, cron, JWT, etc.), the coverage is exhaustive, covering validation, conversion, parsing, and more. Minor gaps exist (e.g., YAML-to-TOML conversion missing), but overall it is remarkably complete.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description only states the basic operation. Missing details on handling invalid input, padding requirements, or error behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The single sentence is efficient and front-loaded with the action. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple decode tool with no output schema and minimal parameters, the description adequately covers the purpose but lacks details on edge cases like padding or whitespace tolerance.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema coverage, the description clarifies the input parameter 'text' as base64-encoded and the output as UTF-8, adding meaningful context beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Base64-decode' and the resource (string), distinguishing it from sibling tools like base64_encode and base64url_decode.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like base64url_decode for URL-safe base64. No context about prerequisites or restrictions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Schema coverage is 0% and description does not explain the 'header' parameter format (e.g., full header line vs value-only). Only mentions 'Content-Type header' in context, leaving ambiguity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'Parse' and resource 'Content-Type header', and specifies outputs 'mime/charset/params'. This distinguishes it from sibling tools that parse other things, though no explicit differentiation is made.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternative parsers like url_parse or user_agent_parse. No mention of prerequisites, typical use cases, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
conventional_commit_lintBInspect
Lint Conventional Commits message (feat/fix/chore…).
| Name | Required | Description | Default |
|---|---|---|---|
| message | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It only states it 'lints' the message, but does not clarify the output format (e.g., returns pass/fail, errors list, or modified message). Without annotations, the agent cannot infer side effects or expected behavior beyond the vague term 'lint'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Very concise one-sentence description that front-loads the core purpose. It efficiently conveys the tool's function without unnecessary verbosity. However, it could benefit from slightly more detail without becoming overly long.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity (one param, no output schema, no annotations), the description is minimal. It tells what the tool does but omits crucial details like return value format, error handling, and acceptance criteria. An agent would need to trial-and-error to understand the tool's full behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has a single required 'message' (string) with 0% description coverage. The description adds that the message should follow Conventional Commits format and lists example types, but does not explain the exact structure or requirements. For a single parameter, this provides some semantic value, but could be more explicit about expected format.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool 'Lint Conventional Commits message' with specific verb 'lint' and resource 'Conventional Commits message'. It further elaborates with example types (feat/fix/chore…), distinguishing it from sibling tools that are general-purpose encoders, parsers, and validators. This provides a precise purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. Among sibling tools, there are other linting and validation tools (e.g., dockerfile_lint, sql_danger_scan), but the description offers no context on when conventional_commit_lint is appropriate or when to use another tool. No exclusionary criteria or prerequisites are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cookie_header_parseCInspect
Parse Cookie request header into name/value map. When: Parse Cookie request headers.
| Name | Required | Description | Default |
|---|---|---|---|
| header | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavioral traits. It mentions the output is a 'name/value map' but does not detail how malformed headers are handled, whether the 'Cookie:' prefix is expected, or any limitations. No destructive or read-only hint is implied, leaving ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, but the second is redundant ('When: Parse Cookie request headers'). It is short but could be more concise by merging the two sentences. The structure is adequate but not efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that there is no output schema, the description should clarify the return format beyond 'name/value map'. It does not address error handling, edge cases, or behavior with multiple cookies. For a simple parsing tool, it is minimally complete but lacks details needed for reliable invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one parameter 'header' with no description and 0% schema coverage. The description does not elaborate on the expected format (e.g., should it include the 'Cookie:' label or just the value?), leaving the agent to guess. No enums or examples are provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it parses a Cookie request header into a name/value map, which is a specific verb and resource. It distinguishes itself from sibling tools like http_headers_parse that parse all headers, but could be more explicit about its unique purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'When: Parse Cookie request headers' line essentially repeats the purpose without providing guidance on when to use this tool versus alternatives, such as using a general HTTP header parser or cookies from a parsed request object. No exclusions or context are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cors_checkBInspect
Check CORS Allow-Origin vs credentials for unsafe combinations.
| Name | Required | Description | Default |
|---|---|---|---|
| origin | No | ||
| allow_origin | Yes | ||
| allow_credentials | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full burden. It states the tool checks for 'unsafe combinations' but does not explain what constitutes unsafe, what output format is returned, or any side effects. This is insufficient for full behavioral understanding.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that conveys the core action without any wasted words. It is highly concise and structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and 0% param coverage, the description is minimal. It lacks details on return values, error handling, and specific unsafe combinations, making it incomplete for an agent to use confidently.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must add meaning. It explains 'allow_origin' and 'allow_credentials' are compared, but 'origin' is not explained. This partially compensates but leaves a gap, warranting a 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'Check' and clearly identifies the resource as 'CORS Allow-Origin vs credentials' for unsafe combinations. This distinguishes it from all sibling tools, none of which focus on CORS.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is used when you need to check CORS configurations, but it does not explicitly state when to use it vs alternatives, nor does it provide any exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cron_describeAInspect
Human-readable natural language description of cron expression (EN + ZH).
| Name | Required | Description | Default |
|---|---|---|---|
| expr | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries full burden. It mentions the output is a human-readable description in EN and ZH, but lacks details on language selection, error handling, or return format. Minimal behavioral disclosure beyond the basic output.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence that conveys the essential information without any unnecessary words. It is front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low complexity and absence of output schema, the description provides a basic understanding but lacks explanation of return values or language options. For a tool with many siblings, more context would be beneficial.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% (no description for the 'expr' parameter). The tool description does not add any additional meaning about the parameter beyond 'cron expression', which is already implied by the parameter name. It does not compensate for the lack of schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: to provide a human-readable natural language description of a cron expression, supporting English and Chinese. It uses a specific verb and resource, and distinguishes it from sibling tools like cron_parse, cron_validate, etc.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus its siblings (e.g., cron_matches, cron_next_runs). The context is implied by the description, but there is no direct comparison or when-not-to-use advice.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cron_matchesBInspect
Check if a cron expression matches a specific datetime (ISO-8601).
| Name | Required | Description | Default |
|---|---|---|---|
| expr | Yes | ||
| at_time | Yes | ISO-8601 datetime | |
| timezone | No | UTC |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It does not mention the return type (e.g., boolean), the expected cron expression format (e.g., 5-field or 6-field), how invalid expressions are handled, or timezone interpretation. This is insufficient for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that efficiently conveys the tool's core functionality. No unnecessary words, and it is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 3 parameters, no output schema, and no annotations, the description is too minimal. It fails to document the return value, cron expression format, timezone handling, or error behavior, making it incomplete for an agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds little beyond the input schema. It repeats the ISO-8601 mention for at_time (already in schema) and provides no additional meaning for expr or timezone. With only 33% schema description coverage, the description should compensate by explaining these parameters further.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: checking if a cron expression matches a specific datetime. It uses a specific verb 'check' and resource 'cron expression matches a specific datetime', which distinguishes it from sibling tools like cron_next_runs or cron_validate.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as cron_next_runs or cron_validate. Given the many sibling tools related to cron, the description should explicitly mention when to choose this tool and when not to.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cron_next_runsBInspect
Preview next N execution times for a 5-field cron expression.
| Name | Required | Description | Default |
|---|---|---|---|
| expr | Yes | ||
| count | No | ||
| timezone | No | UTC | |
| from_time | No | Optional unix or ISO start time |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description should disclose side effects, read-only nature, or constraints. It only says 'preview,' implying no modification, but does not explicitly state that the tool is safe and non-destructive. It also fails to mention timezone handling, error cases, or the 5-field constraint.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no waste, making it easy to parse. However, it is perhaps too concise; it could include a brief note about the count default or timezone behavior without sacrificing clarity. It front-loads the core action but misses ancillary details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 4 parameters, no output schema, and many sibling cron tools, the description is incomplete. It does not explain the return format (timestamps?), error handling for invalid expressions, or behavior when from_time is provided. Users would need to infer or test these aspects.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 25% (only from_time has a description). The tool description hints at 'N' (matching count) and '5-field cron expression' (matching expr), but does not detail defaults or constraints for count and timezone. It adds modest value by emphasizing the 5-field limitation, but overall does not compensate for the low schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Preview next N execution times for a 5-field cron expression.' It specifies a specific verb (preview) and resource (execution times), and the 'N' parameter implies configurability. This distinguishes it from sibling tools like cron_describe (which describes format) and cron_parse (which parses components).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like cron_describe or cron_matches. It does not mention prerequisites, typical use cases, or that it is intended for checking future runs rather than describing syntax or checking matches.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cron_parseBInspect
Parse 5-field cron into named fields (minute hour dom month dow).
| Name | Required | Description | Default |
|---|---|---|---|
| expr | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description must disclose behavior. It only states the parsing action but does not mention whether input validation occurs, error handling, or return format. This is insufficient transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no redundancy. Every word adds value. Ideal conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given one parameter and no output schema, the description is adequate but incomplete. It fails to mention the expected output structure (e.g., object with minute/hour/etc. fields), which would help the agent know what to expect.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% coverage, so the description partly compensates by specifying '5-field cron' format. However, it doesn't provide an example or specify allowed characters (e.g., wildcards, ranges). Minimal added value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Parse' and the resource '5-field cron into named fields'. It distinguishes itself from siblings like cron_validate or cron_describe by focusing solely on parsing.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternative cron tools (e.g., cron_describe, cron_validate). The description lacks context about prerequisites or when parsing is preferred.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cron_semantic_validateCInspect
Validate cron field syntax and value ranges (minute 0-59, hour 0-23, etc.).
| Name | Required | Description | Default |
|---|---|---|---|
| expr | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. Description fails to disclose behavior on validation failure (error or boolean return), side effects (none expected), or return format. Minimal transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with no wasted words. Front-loaded with key action and scope.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and minimal description, the tool's return value (boolean? error object?) is not described. Missing details like whether it accepts seconds field or just standard cron. Incomplete guidance for an AI agent to predict behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Adds some meaning to the 'expr' parameter by specifying expected value ranges (minute 0-59, hour 0-23, etc.), but does not fully describe standard cron expression syntax (e.g., 5 or 6 fields, special characters like '*' '/', ','). Schema has 0% coverage, so description partially compensates.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it validates cron field syntax and value ranges, but lacks differentiation from sibling tools like cron_validate and cron_validate_batch, which likely have overlapping purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., cron_validate, cron_validate_batch). No context for appropriate usage or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cron_validateCInspect
Check cron string has exactly five fields.
| Name | Required | Description | Default |
|---|---|---|---|
| expr | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully convey behavior. It only states what the tool checks but doesn't disclose return format (e.g., boolean, error messages), edge cases, or side effects. This leaves significant ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no unnecessary words. However, it is too brief to be fully helpful, sacrificing completeness for brevity. A balance would be better.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of output schema and annotations, the description should cover output expectations and behavioral details. It does neither, leaving the agent with insufficient information to use the tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% coverage for parameter descriptions, and the tool description adds only that the parameter is a 'cron string.' This adds minimal value beyond the parameter name 'expr' and fails to explain expected format or constraints (e.g., allowed separators).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Check cron string has exactly five fields,' clearly indicating the tool's purpose: validating a cron expression format. This distinguishes it from sibling tools like 'cron_describe' or 'cron_parse' that have different functions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus alternatives such as 'cron_semantic_validate' or 'cron_validate_batch'. The agent receives no help in choosing among similar cron-related tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
cron_validate_batchCInspect
Batch semantic validate of 5-field cron expressions.
| Name | Required | Description | Default |
|---|---|---|---|
| expressions | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It only says 'batch semantic validate' but does not disclose whether it is read-only, what happens on validation failure, or any side effects. This is insufficient for safe invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is highly concise (one sentence) but lacks structure and additional context. While every word earns its place, the terseness leaves gaps that require inference.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and annotations, and the presence of similar sibling tools, the description is incomplete. It does not explain what 'semantic validate' means, what the output looks like, or when batch validation is appropriate over single validation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'expressions' has no schema description (0% coverage). The description only states '5-field cron expressions' but gives no details on format, valid values, or examples. The tool name implies 5-field, but more explicit semantics are needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool validates cron expressions in batch, specifying 'semantic' and '5-field'. This distinguishes it from siblings like cron_validate (non-semantic or single) and cron_semantic_validate (likely single). However, it could explicitly contrast with those siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like cron_validate or cron_semantic_validate. The description does not mention context, prerequisites, or limitations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
csp_parseBInspect
Parse Content-Security-Policy header and flag unsafe directives.
| Name | Required | Description | Default |
|---|---|---|---|
| header | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries the burden of disclosing behavior. It mentions parsing and flagging unsafe directives but does not explain what 'flag' means (e.g., return format), whether it throws errors on invalid input, or if it has side effects. This is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single concise sentence that effectively communicates the tool's purpose without unnecessary words. Well front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no output schema, yet the description does not explain what the output contains (e.g., parsed directives, list of unsafe ones). For a simple tool, this omission reduces usefulness for an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds context that the single 'header' parameter is a Content-Security-Policy header, which helps beyond the schema (0% coverage). However, it does not specify expected format or examples, leaving ambiguity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool parses a Content-Security-Policy header and flags unsafe directives, using a specific verb and resource. It distinguishes from sibling tools, none of which specialize in CSP parsing.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives, nor when not to use it. The description only states what it does, without context for appropriate invocation.

csv_to_jsonCInspect
Convert CSV text to JSON array of row objects. When: Convert CSV rows → JSON array of objects.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It does not disclose key behaviors such as whether the first CSV row is treated as header, delimiter defaults, or handling of quoting/escaping. The minimal description leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short with two sentences, but the second sentence largely repeats the first ('Convert CSV rows → JSON array of objects'). It is concise but not optimally structured, with some redundancy reducing efficiency.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description is incomplete. It fails to specify input format details (e.g., header row assumed, delimiter default) or output structure beyond 'row objects'. This leaves the agent with insufficient information for reliable invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage for the 'text' parameter, and the tool description only mentions 'CSV text' without explaining the expected format, delimiter, or special cases. The description adds little meaning beyond the parameter name.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool converts CSV text to a JSON array of row objects, using a specific verb and resource. However, it does not explicitly differentiate from sibling tools like 'csv_validate' or the reverse 'json_to_csv', so it lacks distinct sibling differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides 'When: Convert CSV rows → JSON array of objects' which implies the usage context but offers no guidance on when not to use this tool or alternatives. There is no mention of prerequisites or exclusions, leaving the agent without clear decision criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
csv_validateAInspect
Validate CSV structure — consistent column counts / header. When: Check CSV column consistency before import.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | ||
| delimiter | No | , | |
| has_header | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description should carry the burden of behavioral disclosure. It says 'Validate' but does not describe return behavior (e.g., boolean, error messages, or side effects). The lack of detail on what constitutes 'consistent' or what happens on failure reduces transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with two short sentences, containing no redundant information. Every word adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has three parameters with no schema descriptions and no output schema. The description only covers the basic purpose, leaving out crucial details about input format requirements, validation outcomes, error handling, and return data. For a validation tool, this is insufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. However, it does not mention any of the three parameters (text, delimiter, has_header) or their roles. The schema provides names and defaults, but the description adds no meaning beyond what the tool name implies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool validates CSV structure, focusing on consistent column counts and header. It distinguishes itself from sibling tools like csv_to_json and csv_validate_batch, and uses specific verbs 'Validate' and 'Check'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When' clause specifying to use the tool before import for column consistency checks. It does not explicitly mention when not to use it, but the context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
currency_convertCInspect
Convert amount between currencies using latest ECB rates.
| Name | Required | Description | Default |
|---|---|---|---|
| amount | Yes | ||
| to_currency | Yes | ||
| from_currency | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description should explain behavioral traits (e.g., rate update frequency, error handling for invalid currencies, API limits). It only mentions using ECB rates, omitting other behavioral nuances.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single concise sentence that conveys the core purpose efficiently. However, it could be slightly more structured but remains front-loaded and clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 3 required parameters, no output schema, and no annotations, the description provides insufficient guidance. Missing information on output format, error states, and usage context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 3 parameters with 0% description coverage. The description does not add meaning beyond parameter names, e.g., no mention of ISO 4217 format, amount constraints, or required precision.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'Convert', resource 'amount between currencies', and data source 'latest ECB rates', distinguishing it from sibling tools like currency_list and currency_rates.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses data source and authentication requirement (no API key). No annotations provided, but description adequately covers behavior for a simple list tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no wasted words. Front-loaded with purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter list tool with no output schema, the description is complete and sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0 parameters (100% coverage), description adds value by specifying source and no API key needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'List', resource 'supported fiat currencies', and adds context 'Frankfurter/ECB, no API key'. Distinguishes from siblings like currency_convert and currency_rates.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies use for listing currencies, not converting or rates. No explicit exclusions, but context is clear given siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
currency_ratesCInspect
Latest exchange rates (Frankfurter ECB data, no API key).
| Name | Required | Description | Default |
|---|---|---|---|
| base | No | USD | |
| symbols | No | Optional target currencies e.g. CNY, EUR |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries full burden. It only mentions 'no API key' and the data source, but omits critical details like rate update frequency, whether rates are real-time, response format, error handling, or rate limits. For an external data fetch tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (one sentence) and front-loaded with key purpose and data source. However, it sacrifices some necessary detail for brevity. Overall, it is effective but could include more without losing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description leaves many gaps. It does not explain the return format, how to handle errors, or the scope of available currencies. For a simple tool this might be borderline, but for an agent to invoke it correctly, more details are needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not mention any parameters. The input schema has two parameters (base and symbols) with only symbols having a description. The base parameter lacks documentation even in the schema. The description adds no value beyond what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool provides 'latest exchange rates' with a specific data source (Frankfurter ECB) and highlights no API key is required. This distinguishes it from siblings like currency_convert (which converts amounts) and currency_list (which lists available currencies).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives. For example, if a user needs to convert currencies, they should use currency_convert; if they need a list of available currencies, use currency_list. The description does not provide such context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
datetime_parseBInspect
Parse unix timestamp or ISO-8601 into UTC ISO + unix.
| Name | Required | Description | Default |
|---|---|---|---|
| value | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description explains the core transformation, but with no annotations, it fails to disclose error handling, accepted input variations (e.g., numeric strings vs. numeric), or whether it validates input. It implies a safe read operation but is not explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is one short sentence, no wasted words, and front-loaded with the verb 'Parse'. It could benefit from a bit more detail without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with no output schema, the description is insufficient. It mentions 'into UTC ISO + unix' but does not specify the return format (e.g., JSON object with keys, or something else). This leaves the agent uncertain about how to use the output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema coverage, the description adds basic meaning: value should be a Unix timestamp or ISO-8601 string. However, it does not specify the exact format (e.g., expected string representation of Unix timestamp, timezone handling in ISO-8601), leaving ambiguity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it parses Unix timestamp or ISO-8601 into UTC ISO + unix, indicating a specific conversion action. However, it does not explicitly say it returns both formats, and it could be more detailed about the output structure.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs. sibling tools like time_convert or timezone_convert. Agent is left to infer context from the tool name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
dependency_versions_extractCInspect
Extract name@version from requirements/lockfile/go.mod/Cargo snippets. When: Extract name@version from lock/requirements snippets (best-effort).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | ||
| ecosystem | No | auto |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description only mentions 'best-effort' to signal potential parse failures. It lacks details on output format, error behavior, or limitations for different ecosystem specifications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two short sentences with repetition ('Extract name@version' appears twice). Could be condensed and front-loaded with the 'When:' context.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no annotations nor output schema, and the description omits return format, error handling, and parameter details. This leaves the agent underinformed for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not explain the 'text' or 'ecosystem' parameters. Given 0% schema coverage, this is a critical gap—the agent has no guidance on what text to provide or how ecosystem affects extraction.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool extracts name@version from specific file types (requirements/lockfile/go.mod/Cargo). This verb+resource combo is unique among siblings, though the phrase 'best-effort' is vague.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a 'When:' clause indicating suitable snippets, but lacks any when-not-to-use guidance or mention of alternative approaches.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
dns_lookupCInspect
DNS lookup for domain (A, AAAA, MX, TXT, NS, CNAME, SOA).
| Name | Required | Description | Default |
|---|---|---|---|
| domain | Yes | ||
| record_type | No | A |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. Description does not disclose behavioral traits such as network dependency, rate limits, error handling, or required permissions. The fact that it performs a network lookup is implied but not stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is a single concise sentence with no wasted words. It is front-loaded with the core function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given two parameters with 0% schema description coverage, no output schema, and no annotations, the description is incomplete. It does not describe the return format (e.g., record type, TTL, value), error cases (e.g., invalid domain, no records), or any additional context needed for an agent to use it effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description lists the record types but does not explain their meanings or how they affect the lookup. For example, doesn't clarify that 'ANY' may return all types. The enum values are self-explanatory for DNS-savvy users, but the description adds minimal value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool performs DNS lookup for a domain and lists supported record types. However, it does not explicitly distinguish from related siblings like 'reverse_dns' or 'whois_lookup', though the specific record types provide implicit differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. No prerequisites, exclusions, or contextual cues for selection among many sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
dockerfile_lintAInspect
Lint Dockerfile for common security/style issues (root user, curl|sh, secrets).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It mentions what issues it checks for but does not disclose the output format, whether it modifies anything, or any other behavioral traits. This is insufficient for a linter tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no wasted words. It efficiently conveys the tool's purpose and scope.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and annotations, the description should describe the return value of the lint operation. It does not, leaving the agent uncertain about how to interpret the result. This is a significant gap for a tool with a single parameter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate. It implies the 'text' parameter is the Dockerfile content, but does not elaborate on expected format or constraints. This is adequate but not rich.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Lint' and the resource 'Dockerfile', and lists specific issue categories (root user, curl|sh, secrets). It effectively distinguishes from sibling tools that target other file types like GitHub Actions or Nginx configs.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
domain_parseCInspect
Parse domain into labels, TLD, registrable domain, subdomain. When: Split domain into subdomain/registrable/TLD (best-effort eTLD).
| Name | Required | Description | Default |
|---|---|---|---|
| domain | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral transparency. It mentions 'best-effort eTLD', hinting at potential inaccuracies, but fails to disclose error handling (e.g., invalid input), return format, or whether the tool is idempotent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two sentences, front-loading the verb and resource. However, the second sentence restates the first partially, adding slight redundancy. Overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one param, no output schema, no annotations), the description is incomplete. It does not specify the output structure (e.g., JSON fields), error behavior for invalid domains, or edge cases. An agent would need to infer expectations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, and the tool description does not clarify the expected format of the 'domain' parameter (e.g., whether to include scheme, port, or just the domain itself). The word 'domain' gives minimal meaning, but no examples or constraints are provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool parses a domain into components like labels, TLD, registrable domain, and subdomain. It distinguishes the tool from sibling url_parse which handles full URLs, though it does not explicitly differentiate from other domain-related tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a 'When' clause indicating the tool should be used to split a domain, but it lacks guidance on when not to use it or alternative tools (e.g., url_parse for full URLs). It implies the context but no exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
duration_parseAInspect
Parse duration (ISO-8601 PnDTnHnMnS or human 1h30m / 90s) to seconds. When: Parse ISO-8601 / human durations to seconds.
| Name | Required | Description | Default |
|---|---|---|---|
| value | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It informs users that the tool accepts two input formats and returns seconds. However, it does not disclose error handling (e.g., behavior on invalid input), output precision, or any constraints like maximum duration length. This is adequate for a simple parser but could be more transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short (two sentences) and front-loaded with the purpose and examples. The second sentence ('When: ...') is somewhat redundant, but the overall structure is efficient and easy to scan.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (1 parameter, no output schema, no nested objects), the description provides sufficient context: input format, output unit, and usage scenario. It does not elaborate on the exact return value, but for a parsing tool that returns a number of seconds, this is likely sufficient for an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage for the single parameter 'value', so the description is essential. It adds critical meaning by explaining that the string can be ISO-8601 ('PnDTnHnMnS') or human-readable formats ('1h30m', '90s'), which is not conveyed by the schema alone.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: parsing ISO-8601 and human-readable durations (with examples like '1h30m', '90s') to seconds. It distinguishes this tool from its siblings (none of which handle duration parsing), making it easy for an agent to select it for duration conversion tasks.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'When: Parse ISO-8601 / human durations to seconds.' line provides explicit context for when to use the tool. Although it does not mention when not to use it or suggest alternatives, the sibling tools are all different parsing/encoding utilities, so the usage scope is well-defined.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
editorconfig_validateCInspect
Validate .editorconfig syntax and common keys.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavior. It only says 'validate syntax and common keys' but does not specify return format (e.g., boolean, error list), side effects, or behavior on invalid input. This is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Very concise single sentence, front-loaded with the action. However, it is too brief and omits important details that could be included without harming conciseness (e.g., what 'common keys' means).
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool (1 param, no output schema, no annotations), the description should at least mention what the output is (e.g., validation success/failure) and perhaps note what 'common keys' are validated. It does not, leaving significant gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% for the single parameter 'text'. The description does not explain what the parameter represents (e.g., content of .editorconfig file as string), nor any constraints or format. It adds minimal value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it validates .editorconfig syntax and common keys. The verb 'validate' and resource '.editorconfig' are specific and unambiguous. No sibling tool covers editorconfig, so differentiation is inherent.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives, no prerequisites, no exclusions. The description lacks any context about typical use cases or limitations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
email_validateAInspect
Validate email address format. When: Syntax-check a single email address.
| Name | Required | Description | Default |
|---|---|---|---|
| Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavior. It only states 'Validate email address format' and 'Syntax-check', but does not specify what validation entails (e.g., format rules), how results are returned, or responses for invalid inputs. This is insufficient for an agent to predict behavior reliably.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with one sentence containing the essential information. It avoids unnecessary words, earning high marks for conciseness. However, it could be slightly more structured (e.g., separating different aspects) without increasing length significantly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low complexity (one string parameter, no output schema), the description provides the basic purpose but lacks details about return format, error handling, or validation scope. It is sufficient for a trivial tool but could be more informative for an agent to handle edge cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, and the description adds no extra meaning beyond the parameter name 'email'. The phrase 'single email address' merely restates the obvious. The description fails to compensate for the missing schema descriptions, offering no additional semantic value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Validate' and the resource 'email address format', and specifies the scope as a single email address. This distinguishes it from sibling tools like 'extract_emails' or other validation tools, making its purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When:' clause indicating it is for syntax-checking a single email address. While it lacks explicit when-not-to-use instructions or alternatives, the context (no similar sibling for email validation) makes the usage clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
env_diffBInspect
Diff two .env files — only_in_a / only_in_b / changed values. When: Diff two .env files for missing/changed keys.
| Name | Required | Description | Default |
|---|---|---|---|
| a | Yes | ||
| b | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description must carry the burden. It states the output categories but does not disclose whether it parses .env format (key=value) or treats lines as strings, nor does it describe the output structure or handling of comments/blanks.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at two sentences, but the second sentence 'When: ...' is redundant and could be integrated into the first. No uninformative details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description lists the types of differences (only_in_a, only_in_b, changed) but lacks specifics on the return format (e.g., array of objects, key-value mapping) and does not cover edge cases like keys missing in both files or malformed lines.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description implies that parameters 'a' and 'b' are .env file contents, but does not clarify whether they are file paths or raw strings. No additional parameter details are provided beyond the parameter names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the verb 'Diff' and the specific resource '.env files'. Lists the output categories (only_in_a, only_in_b, changed values), which differentiates it from general text diff tools like text_diff.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives (e.g., text_diff or env_parse). The 'When:' phrase merely restates the purpose rather than providing contextual usage advice.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
env_parseAInspect
Parse .env / dotenv text into key-value variables.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavior. It states a safe, read-only action (parsing) but does not detail handling of comments, multiline values, or edge cases. Basic transparency is present but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence with no wasted words. It conveys the essential information efficiently.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple parsing tool with one parameter and no output schema, the description adequately explains input and output. However, it could be more complete by explicitly stating the return format (e.g., 'returns an object with key-value pairs').
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter 'text' has 0% schema description coverage, but the description adds meaning by specifying the expected format (.env/dotenv text). This compensates somewhat, though format details (syntax, comments) are missing.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Parse' and the resource '.env / dotenv text', with the outcome 'key-value variables'. This distinguishes it from sibling tools that parse other formats like INI or properties files.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives (e.g., ini_parse, properties_parse). It does not mention when not to use it or any prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
env_required_checkBInspect
Check .env text contains required keys (and non-empty values).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | ||
| required | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. The description only says 'check' but doesn't specify return type (boolean? error?), error handling for missing keys, or whether it validates formatting of the text. Insufficient disclosure beyond basic purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no fluff, efficiently conveys the core action and requirement (non-empty values).
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
While the tool is simple, the description omits output specification (e.g., returns boolean, list of missing keys, or throws error), which is important for an AI agent to know how to handle results. Adequate for basic understanding but incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so description must compensate. It implies 'text' is .env content and 'required' is key list, but doesn't specify the expected format of the text (e.g., key=value lines, newline separation) or constraints on keys. Lacks detail.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool checks a .env text for required keys with non-empty values. It differentiates from siblings like env_parse (which parses) and env_diff (diffs).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like env_parse or manual checking. No context on prerequisites or typical use cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no wasted words. The first sentence states purpose, the second gives usage context. Highly concise and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and 0% schema coverage, the description should explain the return value and edge cases. It does not mention output format, such as whether it returns a list of strings or handles duplicates, leaving the tool underspecified.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, and the description only implies that 'text' is the input. It does not specify encoding, size limits, or expected format, failing to add value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Extract email addresses from text', which is a specific verb-resource combination. It distinguishes from sibling tools like 'email_validate' (validation) and 'extract_urls' (URL extraction).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear usage scenario: 'When: Pull email addresses from free text / logs.' It does not explicitly mention when not to use or list alternatives, but the context is adequate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs. alternatives like regex or other extraction tools. No mention of when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
frontmatter_parseBInspect
Parse YAML frontmatter from markdown (--- ... ---). When: Split YAML frontmatter from markdown body.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose all behavioral traits. It only states the basic operation, omitting details about return format, error handling, or what happens if the input has no frontmatter. This is insufficient for a tool with no output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
While the description is very short and front-loaded, it is under-specified for the task. Conciseness should not sacrifice necessary information; the description fails to provide essential details, making it more deficient than concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple input schema and lack of output schema, the description should still cover return format and error scenarios. The current text is incomplete, leaving gaps that may confuse an agent about expected outputs.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The sole parameter 'text' has no description in the schema (0% coverage), and the tool description adds no additional semantic meaning, leaving the agent without guidance on expected input format or constraints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Parse YAML frontmatter from markdown') and specifies the delimiter format (--- ... ---), making the tool's purpose unambiguous and distinguishing it from other parse tools.

Match paths against .gitignore rules (ignore / negate). When: Test paths against .gitignore rules (best-effort).
| Name | Required | Description | Default |
|---|---|---|---|
| paths | Yes | ||
| gitignore | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior fully. It only mentions 'best-effort' and handles ignore/negate, but omits return format, error behavior, or limitations (e.g., partial rule support).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise—two short sentences. It is front-loaded with the core action and avoids unnecessary words. Every sentence is informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite simple inputs, no output schema exists, so the description should indicate the return type (e.g., boolean, list of matches). It does not. The 'best-effort' hint is vague. Description is incomplete for full agent understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% (no descriptions in schema). The description names 'paths' and 'gitignore' but offers no detail on format (e.g., gitignore string as lines, paths relative paths). Baseline is low; description adds minimal value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool matches paths against .gitignore rules, specifying 'ignore / negate' which adds nuance. However, it does not differentiate from sibling 'gitignore_check', leaving ambiguity about when to use which.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When:' clause but only says 'Test paths against .gitignore rules (best-effort).' It provides no guidance on when not to use, what alternatives exist (e.g., gitignore_check), or any prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
git_url_parseBInspect
Parse git remote URL (ssh/https) into host/owner/repo. When: Parse git@ / https remotes into owner/repo.
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states the parsing action. It does not disclose error handling, validation behavior, or whether network calls are made, leaving significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short (two sentences) but contains redundancy: the second sentence ('When: Parse git@ / https remotes into owner/repo') essentially repeats the first. More efficient consolidation would improve conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has one parameter and no output schema. The description covers the core functionality and output format (host/owner/repo) but does not specify the return structure (object vs. string) or provide examples, leaving some ambiguity for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It specifies that the URL is a git remote in ssh/https format, adding meaning beyond the raw schema. However, it could be more explicit about expected formats (e.g., full URL vs. partial) and does not describe all potential valid inputs.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool parses git remote URLs (ssh/https) into host/owner/repo. It distinguishes from sibling tools like url_parse by specifying 'git remote URL', making the purpose specific and unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implicitly guides usage by saying 'When: Parse git@ / https remotes into owner/repo,' but it lacks explicit when-not-to-use conditions or alternatives among siblings (e.g., url_parse for non-git URLs).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
glob_match_batchCInspect

| Name | Required | Description | Default |
|---|---|---|---|
| paths | Yes | ||
| patterns | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only mentions 'gitignore-style fnmatch' hinting at pattern syntax but omits details like case sensitivity, path format, output behavior, or side effects. A more transparent description would explain what happens with no matches or how paths are resolved.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence front-loading the key action. However, it could benefit from additional structure (e.g., separating purpose and returns), but it remains efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description should explain return values. It does not. The tool's behavior (e.g., returning matches or booleans) is unspecified. For a batch tool, this is a significant gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It names 'paths' and 'patterns' but adds no semantic detail (e.g., whether paths are absolute/relative, pattern syntax variants). The parameter names are self-explanatory but insufficient for correct usage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Match paths against glob patterns (gitignore-style fnmatch),' specifying the verb (Match), resource (paths against glob patterns), and the pattern style. This distinguishes it from sibling tools like gitignore_match or gitignore_check, which are gitignore-specific.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives, such as gitignore_match. No mention of when not to use it, performance considerations, or batch size limits. The description is purely functional.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the action and resource. It is concise and to the point. Could be slightly expanded to explain the parameter, but overall efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given one parameter and no output schema, the description is fairly complete. It specifies the input as a document and caveats with 'best-effort'. It does not detail output format or size considerations, but for a list tool, it covers essential aspects.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides no description for the 'text' parameter (0% coverage). The description implies that 'text' is a GraphQL document by stating 'List GraphQL ops/types from a document', adding minimal meaning beyond the schema. More explicit guidance would improve.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'List' and the resource 'GraphQL query/mutation/subscription names and type defs'. It distinguishes itself from sibling tools like graphql_validate or graphql_schema_diff by focusing on listing operations from a document.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When:' clause indicating the context for use (listing GraphQL ops/types from a document). It does not explicitly mention when not to use or provide alternatives, but the context is clear enough for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Without annotations, description notes focus on breaking changes (removals) but does not clarify if it detects other changes, output format, error handling, or behavior with invalid schemas.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, 11 words, front-loaded purpose. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema and no description of return format. For a diff tool, missing output details (text, object, list of changes) is a significant gap. No annotations to compensate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 'old' and 'new' with no descriptions; description implies they are schemas but does not specify format (string, file, URL) or provide examples. Schema coverage 0%, minimal added value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'diff', specific resource ('two GraphQL schemas'), and purpose ('removed types/fields (breaking changes)'). Distinguishes from siblings like graphql_validate and graphql_operations_list.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool with no output schema, description covers purpose and usage context sufficiently. Could mention return format, but not necessary.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 1 param with 0% description coverage. Description adds 'UTF-8 text' clarifying encoding, which is helpful. However, most meaning is clear from parameter name.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb (hash), resource (text), and output (MD5 hex digest). Distinguishes from sibling hash tools by specifying non-crypto use case.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use: 'MD5 digest (non-crypto integrity / legacy checksums)', implying not for security. No alternative named but context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

The description is a single sentence with no unnecessary words. It is front-loaded with the verb and resource. However, it is under-specified, so conciseness trades off against completeness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool (one parameter, no output schema), the description is minimally adequate. It explains the core function but omits output details and error handling. Could be more complete without verbosity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It identifies the parameter as HTTP status codes but does not explain valid ranges, format (e.g., integer vs string), or that the parameter is an array. The description adds some meaning but substantially incomplete.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool classifies HTTP status codes into bucket ranges (2xx/3xx/4xx/5xx). The verb 'classify' and resource 'HTTP status codes' are specific, and it implicitly distinguishes from the sibling tool 'http_status_lookup' which likely provides status code meanings rather than classification.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like 'http_status_lookup' or other tools. There is no mention of prerequisites, context, or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
http_status_lookupBInspect
Explain HTTP status code (e.g. 404, 429, 503).
| Name | Required | Description | Default |
|---|---|---|---|
| code | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations present; description only says 'explain' without specifying output format or behavior (e.g., returns text string, error handling). Lacks disclosure of traits beyond the basic function.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with examples, front-loaded and no extraneous text. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given low complexity (1 param, no output schema), the description is adequate but leaves gaps: no mention of output type, success criteria, or error handling. For a tool this simple, completeness is marginal.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Parameter 'code' is an integer with 0% schema description coverage. The description adds examples (404, 429, 503), clarifying the meaning of the parameter, but does not specify valid range or format beyond those examples.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool explains HTTP status codes, with specific examples (404, 429, 503). Differentiates from sibling tools like http_status_classify by using 'explain' vs 'classify'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., http_status_classify). No context provided about prerequisites or typical scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
human_bytesAInspect
Format bytes to human size, or parse '1.5 GB' to bytes. When: Format or parse human byte sizes (1.5 GB).
| Name | Required | Description | Default |
|---|---|---|---|
| text | No | ||
| value | No | ||
| precision | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions the bidirectional behavior but does not disclose what happens with conflicting inputs (both text and value), precision application (formatting only or both), or error handling. The description is too terse for full transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with a clear purpose statement and a usage hint. Every word contributes value. No fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple conversion tool, the main functionality is covered. However, without an output schema, the description should explain what the tool returns (e.g., string for format, number for parse) and any limitations. It also lacks details on error handling or precision behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero description coverage, so the description must compensate. It hints at the roles of 'text' (parsing input) and 'value' (formatting input), and 'precision' (rounding), but does not explicitly map each parameter or explain expected formats. This is marginal improvement over raw schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the bidirectional functionality: formatting bytes to human-readable size and parsing human-readable strings to bytes. This clearly distinguishes it from sibling tools like base64_encode or hex_encode.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When:' clause that tells when to use it ('Format or parse human byte sizes'). It implies the context but does not explicitly state when not to use it or provide alternatives. Given the diverse sibling tools, this is sufficient for an agent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
identifier_validateBInspect
Validate identifier for python/javascript/typescript (keywords + syntax).
| Name | Required | Description | Default |
|---|---|---|---|
| name | Yes | ||
| language | No | python |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must carry full burden. It only mentions validation for keywords and syntax but does not disclose return format, error behavior, or non-destructive nature. Lacks essential behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
One-sentence description is extremely concise with no wasted words. Earns its place as a compact summary of purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 2-parameter validation tool with no output schema, the description fails to explain what the tool returns (e.g., boolean, errors) or what 'valid' means. Incomplete for agent to correctly interpret results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must add meaning. It implies 'name' is the identifier and 'language' selects rules, but does not detail what 'name' constraints are or how language affects validation. Adds minimal value beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Validate' and the resource 'identifier' with specific languages (python, javascript, typescript) and scope ('keywords + syntax'). It distinguishes well from sibling tools like email_validate or json_validate.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. No prerequisites, when-not-to-use, or comparisons with other validation tools in the sibling list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
import_list_analyzeAInspect
List imports from python/js source and flag duplicates. Note: best-effort / heuristic — not a full language parser.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | ||
| language | No | python |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It honestly states the heuristic nature, which is good transparency, but it does not explain how duplicates are flagged, whether it has side effects, or any limitations on input size or complexity. The note adds value but is not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, consisting of two short sentences. The primary action is front-loaded, and the critical caveat is provided as a separate note. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity, the description lacks important context: it does not describe the output format (how imports are listed, how duplicates are indicated), potential constraints (e.g., file size limits), or behavior on edge cases (e.g., syntax errors). With no output schema, the description should cover these aspects.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate by explaining parameters. However, it does not describe the 'text' parameter (the source code) nor the 'language' parameter beyond what the enum suggests. No additional meaning is added beyond the schema itself.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists imports from Python/JavaScript source and flags duplicates. This is a specific verb-resource combination, and there are no sibling tools that perform import analysis, so it is sufficiently distinguished.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context about when to use the tool by noting it is a best-effort heuristic and not a full language parser. This implicitly warns against relying on it for precise parsing, but it does not explicitly list when not to use it or suggest alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
ini_parseCInspect
Parse INI / simple key=value config into sections. When: Parse INI/section configs into structured maps.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must bear the burden of behavioral disclosure. It mentions parsing into sections and structured maps, but omits details on error handling, input format nuances (comments, whitespace), or output structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two short sentences, the first is informative and the second is slightly redundant. No extraneous content, but could be merged for efficiency.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lacks necessary details for a parser tool: input format assumptions, output shape, error behavior, and edge cases. With no output schema, the agent is left guessing about the return format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description compensates by stating the input should be INI/simple key=value config, but does not specify syntax details like comment handling or encoding. Minimal added meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool parses INI/simple key=value config into sections, identifying the resource and action. It distinguishes from sibling parsers like properties_parse, though could be more precise about the output structure.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'When' clause gives a brief usage context but does not specify when not to use or compare to alternatives like env_parse or properties_parse. Usage guidance is implied but lacks exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
ip_geolocationAInspect
Geolocate public IP: country, city, lat/lon, timezone, ISP.
| Name | Required | Description | Default |
|---|---|---|---|
| ip | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It accurately describes the core behavior (geolocation) and output fields, but omits details like data source, accuracy, rate limits, or error handling. Adequate for a simple read-only lookup.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single sentence with no filler. Every word is informative, front-loading the purpose and output. Ideal conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so the description covers the return fields adequately. It lacks mention of result format (likely JSON) or error conditions, but for a simple utility tool this is nearly sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description adds essential meaning by listing returned fields and implicitly defining the 'ip' parameter's purpose. It could be improved by specifying expected IP format (IPv4/IPv6) or validation hints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Geolocate public IP') and lists the returned data fields (country, city, lat/lon, timezone, ISP). This distinguishes it from sibling tools like dns_lookup or whois_lookup.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for geolocating public IPs but provides no explicit when-to-use or when-to-avoid guidance. No alternatives are mentioned, leaving the agent to infer context from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that concisely conveys purpose, classification categories, and use case without unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple classification tool with one parameter and no output schema, the description is reasonably complete. It lists the classification categories and hints at the SSRF use case, though it does not describe the output format or error handling.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% coverage and a single parameter 'ip' with no description. The tool name implies IPv4, and the description lists classification categories, but it does not explicitly specify parameter format, validation, or acceptable values.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description specifies a clear verb 'Classify' and resource 'IP' with explicit categories (private/loopback/link-local/global) and the use case 'SSRF helper', distinguishing it from sibling tools like ip_version_detect or geolocation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

| Name | Required | Description | Default |
|---|---|---|---|
| ip | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavior. It only implies classification output but does not describe output format, error handling, or edge cases like invalid IPs. The minimal disclosure is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with the action front-loaded. However, the second sentence is redundant ('When: Classify...' repeats the first sentence's content). Could be more concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
A simple tool with one parameter and no output schema. The description covers the core purpose but lacks details on output and error handling. Adequate but not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% parameter description coverage. The description only implies the 'ip' parameter is an IP address string, but does not specify format, allowed values, or examples. With low coverage, more detail is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it detects IPv4/IPv6 and classifies private/loopback/global, specifying the verb 'Detect' and resource. It differentiates from siblings like ipv4_private_check, but the second sentence is redundant, slightly reducing clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Includes 'When: Classify IPv4/IPv6 and private/global' which explicitly states usage context. However, it does not mention when not to use or provide alternatives, which is acceptable given the narrow scope.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
json_assert_pathsCInspect
Assert JSONPath expressions against JSON (exists/equals/type) — agent self-check.
| Name | Required | Description | Default |
|---|---|---|---|
| data | Yes | ||
| assertions | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior. It only mentions 'agent self-check' without explaining error handling, return format, or whether assertions are silent or produce output. This leaves significant ambiguity for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, using a single sentence that conveys the core functionality. It is front-loaded and avoids unnecessary words. However, it may be too brief for adequate understanding.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (2 params, no output schema, no annotations), the description covers the high-level purpose but lacks details on assertion semantics, return values, and error conditions. It is minimally complete but leaves gaps for an agent to infer.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description does not clarify parameter semantics. It mentions JSONPath and assertion types but fails to explain the structure of the assertions array or the meaning of fields like path, type, equals, exists. The description adds minimal value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool asserts JSONPath expressions against JSON data with operations like exists, equals, and type. It distinguishes from similar tools like jsonpath_query by implying assertion rather than querying, but does not explicitly differentiate from siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

| Name | Required | Description | Default |
|---|---|---|---|
| a | Yes | ||
| b | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavioral traits. It mentions 'deep-compare' but does not explain how it handles nested structures, array order, type differences, or whether it modifies anything. Critical details like performance, edge cases, and output behavior are missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence of nine words, highly concise. It conveys the core purpose without waste, but could be slightly front-loaded with more critical detail. Still, it is appropriately sized for a straightforward tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool performing deep comparison with no output schema, the description is too brief. It does not explain the output format (list of paths), return type, error handling, or behavior with invalid inputs. Given the complexity and lack of annotations, more detail is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must add meaning to parameters. It describes parameters as 'two JSON documents' but does not clarify that they are JSON strings, object representations, or valid JSON inputs. The schema only specifies 'string', lacking format constraints. Minimal value added.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the function: deep-compare two JSON documents and list differing paths. It uses specific verbs and resource, and distinguishes from siblings that might not list paths explicitly, though it could be more precise about the output format.

|---|---|---|---|
| text | Yes | ||
| separator | No | . |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It only states the basic behavior of flattening without disclosing how arrays, null values, or circular references are handled. More detail is needed for a safe operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences: first states the operation, second gives usage context. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with no output schema and no annotations, the description is incomplete. It does not describe the output format or behavior with edge cases, leaving gaps for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It hints at the default separator (dot) but does not explain the 'text' or 'separator' parameters beyond their existence. Adds minimal value over the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action 'flatten' and the resource 'nested JSON', and specifies the output format 'dot-key map'. It distinguishes the tool from siblings like json_format or json_to_csv by focusing on flattening.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'When:' clause provides explicit guidance: 'Flatten nested JSON keys before comparing or exporting.' This tells the agent when to use the tool, though it lacks exclusion criteria or alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
json_formatBInspect
Pretty-print JSON with indent. When: Pretty-print JSON when the agent needs readable output.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | ||
| indent | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states 'pretty-print' which implies a non-destructive formatting operation, but does not disclose whether it validates JSON, what happens on invalid input, or any other behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short (two sentences) and front-loaded with the core purpose. It wastes no words, though it could add a bit more detail without losing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple tool and absence of output schema, the description should at least specify the output format (e.g., a formatted JSON string) and confirm it is read-only. It does not provide this, and with many JSON sibling tools, it lacks distinguishing guidance.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% with no parameter descriptions. The description mentions 'with indent' but does not explain that 'text' should be a JSON string or the unit/range of 'indent'. This forces the agent to infer parameter semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the action 'pretty-print JSON' and the resource 'JSON'. It also provides a use case 'when the agent needs readable output', which distinguishes it from other JSON tools like validation or conversion.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When' clause ('when the agent needs readable output'), offering some usage context. However, it does not explicitly exclude use cases or compare with alternatives (e.g., json_minify, json_validate), leaving room for ambiguity.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
jsonl_validateCInspect
Validate JSON Lines (NDJSON); optional per-line JSON Schema. When: Validate NDJSON / JSON Lines logs or datasets.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | ||
| schema | No | ||
| max_lines | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations present, so description carries full burden. It does not disclose error handling behavior, return format, whether validation stops at first error or accumulates, or performance implications. The description is too vague.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, very concise. However, conciseness sacrifices critical details. The structure is clear but under-specified for a validation tool. Could be longer to cover essential behavior.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Tool validates NDJSON with optional schema—medium complexity. No output schema, no error handling description, no mention of per-line behavior. Among many sibling validation tools (e.g., json_validate, csv_validate), description does not sufficiently complete the picture for an agent to use confidently.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description mentions 'optional per-line JSON Schema' which hints at the schema parameter, but does not explain the purpose of 'text' (expects JSON Lines?), 'max_lines' (default 200) is unmentioned. Adds minimal value beyond bare schema names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool validates JSON Lines (NDJSON) with optional per-line JSON Schema. It gives a use case (validate logs or datasets) and distinguishes from general JSON validation tools like 'json_validate'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions 'When: Validate NDJSON / JSON Lines logs or datasets' which implies usage context but does not provide explicit when-not-to-use or alternatives among sibling tools. No reasoning about trade-offs.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
json_mergeBInspect
Deep-merge two JSON objects (second overlays first).
| Name | Required | Description | Default |
|---|---|---|---|
| a | Yes | ||
| b | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description describes the merge behavior (deep-merge with overlay), which is adequate for a simple operation. However, it does not disclose whether inputs are expected as JSON strings (as schema implies) or already parsed objects, nor does it mention side effects, output format, or error handling. With no annotations, the description carries the full burden but leaves gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the key concept 'deep-merge'. Every word serves a purpose, and there is no unnecessary repetition or verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with no output schema and no annotations, the description is too brief. It omits output format (likely a JSON string), validation of inputs, and differentiation from siblings like json_merge_patch. The agent lacks enough context to confidently use the tool without guessing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has no descriptions for parameters a and b (0% coverage), and the description only mentions 'two JSON objects' without explaining that inputs must be JSON strings or providing format details. This adds little meaning beyond the schema's type field.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs a deep-merge of two JSON objects, specifying that the second overlays the first. This is specific and includes the verb 'merge' and resource 'JSON objects', but does not explicitly differentiate from the sibling json_merge_patch, which follows a different RFC.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidance is provided. The description does not indicate when to use this tool versus alternatives like json_merge_patch or json_equal, nor does it mention any prerequisites or conditions for use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and low parameter coverage, the description lacks essential context such as return type, error conditions, and usage constraints. It is insufficient for an agent to reliably invoke the tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, yet the description adds no meaning to the two parameters ('data', 'patch'). It does not specify expected format (e.g., JSON string), required structure, or examples, leaving the agent without critical guidance.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as applying RFC 6902 JSON Patch operations and lists the supported ops (add/remove/replace/test/move/copy), distinguishing it from sibling tools like json_merge_patch or json_format. However, the second sentence is redundant.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., json_merge_patch, json_pointer_get). The phrase 'When: Apply RFC 6902 ops' merely restates the purpose, not a usage condition.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

| path | Yes | e.g. $.store.book[*].author | |
| text | Yes | JSON text |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only says 'returns matching values' without specifying whether it returns all matches, first match, or format of the result. No mention of error handling (e.g., invalid path) or limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise at two sentences. However, it omits some useful detail (e.g., return format), so it's not maximally informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity and lack of output schema, the description provides the core functionality. However, it misses details like return type (e.g., array of values) and behavior on no matches, which are useful for completion.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with both parameters described in the schema. The description adds no additional meaning beyond the schema, so a baseline of 3 is appropriate.

json_to_yamlAInspect
Convert JSON text to YAML string. When: Convert JSON → YAML for config files agents write.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose any behavioral traits such as error handling, size limits, or whether the operation is read-only. For a conversion tool, this lack of detail reduces transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, very concise, and front-loaded with the core purpose. Every word serves a purpose without extraneous content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool and the absence of an output schema, the description is adequate but lacks details about output format (e.g., indentation, type preservation). For a config file use case, more context could be beneficial.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 0%, and the description only specifies that the parameter is 'JSON text', which adds basic meaning but does not elaborate on format requirements, validation, or edge cases. The single parameter is straightforward, but more detail would help.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Convert JSON text to YAML string', which is a specific verb and resource. The additional 'When' clause provides a concrete use case, differentiating from sibling conversion tools like yaml_to_json.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When' clause that gives context (config files agents write), indicating when to use the tool. However, it does not explicitly mention when not to use it or compare with alternatives, though the purpose is clear from the name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
json_type_summaryCInspect
Summarize JSON value types (counts per type in tree).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It mentions 'in tree' suggesting recursion, but does not disclose whether it handles nested structures, arrays, or empty inputs, nor the output format.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that conveys the core purpose without unnecessary words. However, it could benefit from slight expansion for completeness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (tree traversal, type counting) and the absence of output schema or annotations, the description is too sparse. It does not explain what counts are returned or how types are categorized.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'text' is not described in the schema (0% coverage). The tool description implies it expects a JSON string, but adds no details about valid formats or constraints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'summarize' and the resource 'JSON value types', further specifying 'counts per type in tree'. This distinguishes it from sibling tools like json_validate or json_format.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like jsonpath_query or json_schema_validate. The description implies use when summary is needed, but lacks explicit context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
json_validateCInspect

| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior. It states validation and return of parsed object or error, but does not detail error format, whether it throws an exception, or how the parsed object is structured. The behavioral disclosure is minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, directly stating the action and result. It is concise and front-loaded with the key purpose and return behavior. No unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter, the description is minimally sufficient. However, it lacks details on error handling and return structure, which would be helpful for an agent. Context is adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must add meaning. It mentions 'Validate JSON text' but does not explain the expected format of the 'text' parameter beyond being a string. The parameter semantics are barely enhanced by the description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description specifies 'Validate JSON text' with a clear verb and resource. It also indicates the return of a parsed object or error. However, it does not distinguish from sibling tools like jsonl_validate or json_schema_validate, which validate JSON Lines or against a schema. The purpose is clear but lacks differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives (e.g., jsonl_validate, json_schema_validate). There is no mention of prerequisites or context. The description offers no usage direction beyond the basic action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low schema coverage, no output schema, and the tool's simplicity (line ending normalization), the description is incomplete. It fails to specify the return value, error cases (e.g., invalid style parameter), or edge cases (e.g., empty input). An agent would lack confidence in using it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description should compensate. It mentions the enum values (lf/crlf/cr) for the style parameter but does not describe the required text parameter or how they interact (e.g., default behavior when style is omitted). The description adds minimal semantics beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it detects and normalizes line endings to lf/crlf/cr. This distinguishes it from sibling tools like unicode_normalize which handle Unicode normalization. However, it could be more explicit about the text resource (e.g., 'normalizes line endings in a text string').
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When:' hint: 'Detect/normalize CRLF vs LF.' This implies usage context for detecting CRLF vs LF inconsistencies. However, it does not explicitly state when not to use this tool or mention alternatives among siblings.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description should indicate the return format (e.g., a string containing markdown list). It does not address this, nor does it mention the structure of the TOC (e.g., nested list with links?). The tool is simple but still missing essential context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description should explain parameters. It does not describe the 'text' parameter (must be markdown content) or the 'max_level' parameter (controls heading depth). The description adds no semantic value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it builds a table of contents from markdown headings, specifying the verb and resource. It distinguishes itself from siblings like markdown_to_html and markdown_link_extract by focusing specifically on TOC generation, though it doesn't explicitly name them.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The phrase 'When: Build heading TOC from markdown docs' gives a basic usage context but lacks guidance on when not to use this tool or alternatives. It implies a specific scenario but offers no exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
markdown_to_htmlAInspect
Convert Markdown text to HTML. When: Render markdown → HTML for previews or emails.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry full behavioral disclosure. It only states the conversion action without detailing markdown flavor support, limitations, error handling, or side effects. For a conversion tool, this is insufficiently transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences: one for purpose and one for usage context. No superfluous content. Every word adds value, making it highly efficient for an agent to parse.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and no output schema, the description is minimally adequate. However, it lacks details about markdown spec, output behavior, and edge cases, which would be expected for completeness without annotations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description implies the single parameter 'text' is markdown content. This adds some meaning beyond the schema's raw type, but it does not specify format, encoding, or constraints, so baseline compensation is minimal.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose with a specific verb ('Convert') and resource ('Markdown text to HTML'). It adds a usage hint ('for previews or emails'), but does not differentiate from the sibling tool 'html_to_markdown' or other converters.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit context for when to use the tool ('Render markdown → HTML for previews or emails'). However, it does not mention when not to use it or suggest alternatives (e.g., for more complex conversions).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
mime_lookupAInspect
Lookup MIME type by file extension/path, or extensions by MIME. When: Map file extension ↔ MIME type.
| Name | Required | Description | Default |
|---|---|---|---|
| mime | No | ||
| path_or_ext | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It only states the basic function without detailing error handling, case sensitivity, partial matches, or output format. This lack of detail limits transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise: two short sentences with no wasted words. Key information is front-loaded, making it quickly scannable for an AI agent.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of an output schema and annotations, the description should compensate by explaining return values or behavior details. It does not mention what the tool returns (e.g., a string, list, or object), leaving the agent guessing about the output format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description mentions 'file extension/path' and 'MIME' but does not explicitly link them to the two parameters or clarify their relationship (e.g., which to use when). Both parameters are optional, and the description fails to guide selection.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the bidirectional mapping between file extension/path and MIME type, using specific verbs ('Lookup', 'Map'). This distinguishes it from the many sibling tools, none of which perform MIME lookups.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes 'When: Map file extension ↔ MIME type', providing explicit context for when to use the tool. However, it does not mention when not to use it or alternatives, though among siblings no alternative exists.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
nanoid_generateBInspect
Generate URL-friendly nanoid (like npm nanoid).
| Name | Required | Description | Default |
|---|---|---|---|
| size | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full transparency burden. It states the output is URL-friendly, implying safe characters, but does not disclose whether it is cryptographically secure, performance characteristics, or any side effects. Minimal but acceptable for a simple generator.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, making it concise and easily parseable. It front-loads the core action, but lacks any structural elements like examples or breakdowns. Still, it avoids unnecessary verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple one-parameter schema and no output schema, the description could have been sufficient, but it omits critical context: no parameter explanation, no usage guidance, and no details about the generated ID (e.g., character set, uniqueness). Incomplete for a reliable agent decision.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description does not mention the 'size' parameter at all, despite schema description coverage being 0%. It fails to explain how size affects the output or its allowable range (1-64, default 21). The agent gets no value beyond the raw schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool generates a URL-friendly nanoid, explicitly referencing 'like npm nanoid', which is a well-known library. This distinguishes it from sibling tools like uuid_generate or random_string by specifying the format.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool over alternatives (e.g., uuid_generate, random_string). It does not mention any context or prerequisites, leaving the agent to infer usage without explicit direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
nginx_config_lintAInspect
Lint nginx config snippets (braces, SSLv3, server_tokens, HSTS hints).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It lists example checks (e.g., braces, SSLv3) but does not explicitly state that the tool is read-only or non-destructive (though 'lint' implies analysis). The description lacks details on side effects, performance, or what happens on success/failure. It does not contradict any annotations since none exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence of 15 words, front-loading the main verb 'Lint' and immediately providing specific example checks. Every word adds value; no filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is adequate for a simple tool with one parameter, but it lacks information about the return value/format (e.g., list of errors or warnings) and does not specify whether it validates syntax or only the listed checks. Since there is no output schema, the description could be more complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has one required parameter 'text' with no description (0% coverage). The description adds meaning by specifying that the text is an nginx config snippet and mentions example lint checks, clarifying what kind of input is expected. Though it could be more explicit about the expected format, it significantly compensates for the schema's lack of parameter descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lints nginx config snippets and lists specific checks (braces, SSLv3, server_tokens, HSTS hints). It uses a specific verb ('Lint') and resource ('nginx config snippets'), and among the many sibling linting tools (e.g., dockerfile_lint, github_actions_lint), this is uniquely for nginx.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool should be used when you have nginx config snippets to lint, but it does not provide explicit guidance on when to use vs alternatives, nor does it state when not to use it. No exclusions or alternative tool suggestions are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
openapi_diffAInspect
Compare two OpenAPI specs and flag breaking vs non-breaking API changes.
| Name | Required | Description | Default |
|---|---|---|---|
| new | Yes | New OpenAPI JSON/YAML | |
| old | Yes | Previous OpenAPI JSON/YAML |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It adds the key detail of breaking vs non-breaking classification, which is non-obvious. However, it does not disclose how results are returned (e.g., list, summary, diff object) or error handling behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single, concise sentence of 12 words that conveys the core functionality without any fluff. It is well-structured and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool lacks an output schema and the description does not clarify what 'flag' means (e.g., return list, diff object, status). Given the complexity of diffing OpenAPI specs, more details about the output format are needed for the agent to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with clear parameter descriptions for 'old' and 'new'. The tool description restates these as 'two OpenAPI specs' but adds no additional semantic value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: compare two OpenAPI specs and classify changes as breaking or non-breaking. This distinguishes it from similar siblings like graphql_schema_diff or openapi_validate.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage in API migration or review scenarios but does not explicitly state when to use it versus alternatives like openapi_validate or graphql_schema_diff. No when-not-to-use guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
openapi_operations_listAInspect
List OpenAPI path operations (method, path, operationId, tags). When: List OpenAPI operations before validate/diff.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears the full burden of behavioral disclosure. It does not mention whether the tool is read-only, its safety profile, or any prerequisites. The behavior is implied but not explicitly stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two short sentences, front-loading the core purpose. Every word adds value, and there is no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the basic functionality and usage context, but lacks details about input format, return structure, and error cases. Given the simplicity of the tool and lack of output schema, more completeness would be beneficial.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter 'text' is not described in the schema (0% coverage) and the description does not explain what it represents. Users must infer it is the OpenAPI specification content, which is not explicit.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool lists OpenAPI path operations and specifies the fields returned (method, path, operationId, tags). It distinguishes from sibling tools like openapi_diff and openapi_validate by mentioning it's a precursor step.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states when to use the tool ('before validate/diff'), which is a clear usage context. However, it does not mention when not to use it or provide alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
openapi_validateAInspect
Validate OpenAPI 3.x document (JSON or YAML snippet).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It only says 'validate' without disclosing whether it returns a boolean, error messages, or any behavioral traits like side effects or limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded with key information, no redundant or extraneous content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Lacks details about return value or validation result format. As there is no output schema, the description could be more complete to help the agent understand what to expect.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage; the tool description adds that the 'text' parameter expects an OpenAPI 3.x document in JSON or YAML format, providing meaning beyond the raw schema type.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Validate OpenAPI 3.x document', specifying verb and resource. It also mentions 'JSON or YAML snippet', distinguishing it from sibling OpenAPI tools like openapi_diff and openapi_operations_list.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool over alternatives such as json_validate, yaml_validate, or other OpenAPI tools. No mention of prerequisites or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
package_manifest_auditAInspect
Audit package.json or pyproject.toml — license, risky scripts, loose ranges; emit semver_checks for batch. Note: best-effort / heuristic — not a full language parser.
| Name | Required | Description | Default |
|---|---|---|---|
| kind | No | auto | |
| text | Yes | Manifest file contents |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that the tool is best-effort/heuristic and not a full parser, which adds behavioral context. However, it does not explicitly state that the tool is read-only or safe, which would be helpful.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise: a single sentence plus a brief note. No wasted words, and the main action is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the tool's purpose, scope (manifest files), and limitation (heuristic). It mentions output direction ('emit semver_checks for batch') but does not detail the output structure. Given no output schema, this is sufficient but could be more explicit.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 50% (text param has description, kind does not). The description does not add any parameter-specific information beyond what the schema provides, failing to compensate for the missing schema documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool audits package.json or pyproject.toml for license, risky scripts, and loose ranges, and emits semver_checks for batch. This is specific and distinguishes it from sibling tools like dependency_versions_extract or requirements_audit.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for auditing manifest files but does not explicitly state when to use or avoid this tool. It mentions 'best-effort / heuristic' as a caution but lacks explicit alternatives or exclusion criteria.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
package_scripts_listBInspect
List scripts from package.json or pyproject.toml (poetry/PEP 621). When: List npm/poetry/PEP 621 scripts from manifests.
| Name | Required | Description | Default |
|---|---|---|---|
| kind | No | auto | |
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It does not disclose output format, file system interaction, or mutation behavior. The tool is likely read-only, but this is not confirmed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, but the second sentence repeats the first. It could be more concise and front-loaded. No structural issues beyond redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description should explain what the tool returns. It does not. Also, it does not specify whether 'text' is file content or a path, leaving ambiguity for a tool with only two parameters.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, meaning the description does not explain parameters. The 'text' parameter's role (content vs. path) is ambiguous, and 'kind' is not explained despite being an enum.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it lists scripts from package.json or pyproject.toml. It specifies the verb (list) and resource (scripts from manifests), but the second sentence is redundant, slightly lowering clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'When' prefix explicitly tells when to use this tool. There are no similar sibling tools, so alternatives aren't needed, but it lacks explicit exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
password_generateCInspect
Cryptographically secure random password.
| Name | Required | Description | Default |

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Very concise but lacks structured parameter details; fronts purpose but omits critical parameter information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Incomplete for a tool with 2 parameters and many siblings; does not specify output characteristics or constraints like supported character sets.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameter descriptions in schema (0% coverage) and description does not explain 'length' or 'symbols' parameters, failing to add value beyond names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly indicates it generates a cryptographically secure random password, distinguishing it from sibling tools like nanoid_generate or random_string.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this vs alternatives; lacks when-not or context for selection among sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
password_strengthBInspect
Offline password strength heuristic (length/classes/common). When: Offline password strength heuristic (not a cracker).
| Name | Required | Description | Default |
|---|---|---|---|
| password | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must fully disclose behavior. It mentions 'offline' and 'heuristic' but omits important traits like return format (score/boolean/detail), performance characteristics, or whether it checks against common password lists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short (two sentences) but contains repetition of 'Offline password strength heuristic.' It could separate purpose from usage more clearly, but it is reasonably concise for a simple tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and a single parameter, the description should explain what the tool returns (e.g., a score, enum, or text). It fails to do so, leaving the agent guessing about the result format and completeness of the assessment.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% (no descriptions in schema), and the description adds nothing about the 'password' parameter beyond what the schema already indicates (it's a string). The description fails to specify format, constraints, or expected behavior for various inputs.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it's an offline password strength heuristic using length, character classes, and common patterns. This distinguishes it from siblings like password_generate or hash functions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly says 'When: Offline password strength heuristic (not a cracker),' providing clear context for when to use it. However, it doesn't exclude alternatives or provide detailed comparison with similar tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
path_normalizeAInspect
Normalize filesystem path (resolve . and ..) for posix or windows. When: Resolve . and .. in filesystem paths.
| Name | Required | Description | Default |
|---|---|---|---|
| path | Yes | ||
| style | No | posix |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions the style parameter (posix/windows) but does not describe edge cases, error handling, or behavior for invalid paths. For a simple utility, this is adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the action ('Normalize filesystem path'), and contains no unnecessary words. Every part serves a purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description should cover behavior thoroughly. It explains purpose and style but lacks details on return format, error behavior, or edge cases (e.g., empty path, root path). Minimal but functional for a simple tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must add value. It does clarify the 'style' parameter by mentioning posix and windows, but does not explain the 'path' parameter format or what normalization entails beyond resolving . and .. . Partial improvement over schema alone.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool normalizes filesystem paths by resolving '.' and '..' for both posix and windows. It uses a specific verb ('normalize') and distinguishes from sibling tools like 'path_safety_check' which focuses on safety, not normalization.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes 'When: Resolve . and .. in filesystem paths', which explicitly states a use case. However, it does not mention when not to use or compare with alternative tools. Given the lack of directly competing siblings, the guidance is present but could be more explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
path_safety_checkCInspect
Check filesystem path for traversal / absolute / sensitive system paths.
| Name | Required | Description | Default |
|---|---|---|---|
| path | Yes | ||
| allow_absolute | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It states the tool 'checks' but does not specify whether it returns a boolean, throws errors, or modifies the path. This is insufficient for a security tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no waste, but it is under-informative. It could benefit from adding parameter details without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has two parameters, no output schema, and no annotations. The description lacks details on return behavior or parameter semantics, making it incomplete for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description should explain parameters. It does not describe the 'path' parameter format or the effect of 'allow_absolute'. The latter defaults to false, implying absolute paths are flagged, but this is not stated.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool checks filesystem paths for traversal, absolute paths, and sensitive system paths. This distinguishes it from sibling tools like path_normalize, which focus on normalization rather than security checks.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries the burden. It discloses output attributes but does not cover error behavior, handling of malformed PEM, or multiple blocks. This is minimally acceptable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single, front-loaded sentence with no redundancy. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite simplicity, the description omits return format, handling of no matches, and any prerequisites. With no output schema, more detail is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description clarifies that the single 'text' parameter is the input containing PEM blocks. With 0% schema documentation, this adds necessary meaning beyond the schema's 'string' type.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'List' and the resource 'PEM blocks', and specifies the output attributes (label, DER size, SHA256 fingerprint). This differentiates it from siblings like base64_decode (raw decode) and x509_parse (certificate parsing).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one required parameter 'text' with 0% description coverage. The description does not clarify what 'text' should contain (e.g., raw content of requirements.txt, a file path, or a URL). This is a critical omission for effective tool selection and invocation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool audits Python requirements.txt files specifically for unpinned, VCS, and deprecated packages. Among sibling tools like 'package_manifest_audit' (for other formats) and 'dependency_versions_extract', it distinguishes itself by targeting Python requirements.txt and specific audit checks.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use when auditing Python requirements.txt files but does not explicitly state when to use this tool versus alternatives like 'dependency_versions_extract' or 'package_manifest_audit'. No when-not-to-use or exclusion criteria are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
reverse_dnsCInspect
Reverse DNS (PTR) lookup for IP address.
| Name | Required | Description | Default |
|---|---|---|---|
| ip | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description should disclose behavioral traits like output format, error handling, rate limits, or side effects. It only states the basic operation, leaving the agent uninformed about what to expect or whether the tool is safe.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise (one sentence) but lacks structure or additional detail. It is not verbose, but the brevity sacrifices clarity on nuances like return format and usage context.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description should provide more complete context including expected output (e.g., domain name or record) and possible failure modes. The current description leaves significant gaps for an agent to make informed decisions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The sole parameter 'ip' is a string with 0% schema description coverage. The description adds no extra meaning (e.g., supported formats, validation rules) beyond the parameter name. The type 'string' alone is insufficient for an agent to construct valid input.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Reverse DNS (PTR) lookup for IP address' clearly states the specific operation (PTR lookup) and the resource (IP address). It is distinct from sibling tools like dns_lookup and whois_lookup, which cover different DNS and IP-related functions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives (e.g., for forward DNS lookups, use dns_lookup). There is no mention of prerequisites, limitations, or recommended contexts.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
robots_txt_validateCInspect
Validate robots.txt syntax and User-agent rules.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility. It fails to mention whether the tool returns errors, warnings, or a simple pass/fail, nor does it describe any side effects or required permissions. The description only states the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is front-loaded with the action verb. However, it is overly terse and could include more useful information without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one input, no output schema), the description should provide enough context for an agent to understand the output format or validation behavior. It falls short by not describing what the validation result looks like or any examples.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one required parameter 'text' with type string, but the description does not explain it at all. With 0% schema description coverage, the description should clarify what the parameter expects (e.g., full robots.txt content) but it does not.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Validate robots.txt syntax and User-agent rules,' which includes the specific verb 'validate' and the resource 'robots.txt'. It distinguishes itself from sibling tools as no other tool deals with robots.txt files.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. Although there are no sibling robots.txt tools, the description does not offer any context about appropriate usage scenarios or limitations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
secrets_scanAInspect
Scan text for hardcoded secrets (API keys, tokens, private keys). Returns redacted findings.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | ||
| min_entropy | No | Entropy threshold for heuristic strings |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It states that the tool returns 'redacted findings', implying it modifies the text to hide secrets, but does not clarify if the input is modified or if it is read-only. It also lacks details on performance, rate limits, or permissions. This is adequate but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two sentences, front-loaded with the core action and output. Every word adds value, with no fluff or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple scanning tool with no output schema, the description covers the basic function and return value. However, it could mention that results are likely a list or structured output, and how redaction is performed. Overall, it is mostly complete for the complexity level.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 50%; only min_entropy has a description. The description does not explain the 'text' parameter format or constraints, nor does it add value to min_entropy beyond what schema provides. The description should compensate for the missing param description but fails to do so.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool scans text for hardcoded secrets like API keys, tokens, and private keys, and returns redacted findings. It provides specific verb+resource and lists examples, distinguishing it from sibling tools which are mostly encoding/decoding or general utilities.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide any guidance on when to use this tool versus alternatives or when not to use it. There is no mention of prerequisites, edge cases, or comparisons to similar tools like html_security_scan or password_strength.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
semver_compareBInspect
Compare two semver strings (less / equal / greater).
| Name | Required | Description | Default |
|---|---|---|---|
| a | Yes | ||
| b | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the behavioral burden. It only states the comparison outcome but does not mention error handling (e.g., invalid semver), side effects, or safety (read-only).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single, clear sentence with no extraneous information. Efficiently communicates the core functionality.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema is provided, and the description does not specify the return format (e.g., integer -1/0/1 or string 'less'/'equal'/'greater'). Error handling and edge cases are omitted. Incomplete for a comparison tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description implies 'a' and 'b' are semver strings but adds no format constraints or examples. This is insufficient for an agent to know proper input format (e.g., must be valid semver).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'compare' and the resource 'two semver strings' with explicit outcomes 'less / equal / greater'. It distinguishes well from sibling tools like semver_satisfies or semver_parse.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus alternatives (e.g., semver_satisfies for range checks). The agent must infer from context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
semver_incBInspect
Bump a semver version by major/minor/patch. When: Bump major/minor/patch when cutting a release.
| Name | Required | Description | Default |
|---|---|---|---|
| release | No | patch | |
| version | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full behavioral burden. It states the tool bumps a version, but does not disclose whether it validates the input format, what happens on invalid input, or what the output format is. This lack of detail reduces transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, with two short sentences that are front-loaded. Every word is meaningful and there is no redundancy. It earns its place efficiently.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no output schema, so the description should explain what the tool returns. It does not mention the output format or behavior, leaving the agent without complete information for simple usage like reading the resulting version.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must add meaning. It mentions 'major/minor/patch' which relates to the 'release' parameter enum, but does not describe the 'version' parameter at all. It adds minimal value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'bump' and the resource 'semver version', specifying the possible increments (major/minor/patch). It distinguishes the tool from siblings like semver_compare or semver_parse by indicating it is used for incrementing versions when cutting a release.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes 'When: Bump major/minor/patch when cutting a release', which provides explicit context for when to use the tool. It does not explicitly state when not to use, but the context makes it clear this is for incrementing, not comparing or parsing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
semver_max_satisfyingBInspect
Pick the highest version that satisfies a semver range (npm-style).
| Name | Required | Description | Default |
|---|---|---|---|
| range | Yes | ||
| versions | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It does not state what happens if no version satisfies the range (e.g., returns null or throws), nor any side effects or permissions. The npm-style hint is useful but insufficient for full transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single sentence with 10 words, front-loading the core purpose. Every word is necessary, and no redundant information is present.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low complexity (2 simple params, no output schema), the description is mostly adequate. However, it fails to indicate the return value (string version or null) and does not mention edge cases like invalid range or empty versions list.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It adds the semantic detail that the range is 'npm-style', which clarifies the expected format. However, it does not describe the 'versions' array beyond the schema definition, leaving the full burden on parameter names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('pick') and identifies the resource ('highest version') with the constraint ('satisfies a semver range'). It clearly distinguishes from sibling tools like semver_satisfies (checks boolean) and semver_sort (orders versions). The phrase '(npm-style)' further clarifies the semver variant.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives like semver_satisfies_batch or semver_compare. The usage is implied by the tool's name and description, but there is no 'when to use' or 'when not to use' advice.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
semver_parseBInspect
Parse semver string into major, minor, patch, prerelease.
| Name | Required | Description | Default |
|---|---|---|---|
| version | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior. It lists output components but omits crucial details: output format (object or array?), behavior on invalid input, and whether build metadata is included. This leaves ambiguity for the AI agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence with no extraneous words. Every part adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description lacks details about the return structure and error handling. For a parse tool without an output schema, this information is critical for the agent to use the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds minimal meaning beyond the schema, stating the input should be a 'semver string'. With 0% schema description coverage, more detail (e.g., expected format, validation criteria) is needed to compensate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states that the tool parses a semver string into its components (major, minor, patch, prerelease). This distinguishes it from sibling tools like semver_compare and semver_inc, which have different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for decomposing a version string, but provides no explicit guidance on when to use this tool over alternatives like semver_sort or semver_satisfies. Given the many semver siblings, more guidance would be helpful.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
semver_range_intersectsCInspect
Heuristic check whether two semver ranges share any sample versions (conflict hint).
| Name | Required | Description | Default |
|---|---|---|---|
| range_a | Yes | ||
| range_b | Yes | ||
| samples | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries full burden. It mentions 'heuristic' suggesting imprecision but does not elaborate on the algorithm (e.g., sample generation vs. exact intersection check). The role of the 'samples' parameter is ambiguous: does the tool use those samples, or does it generate them? This lack of detail limits transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, which is concise, but it omits necessary details such as return type, parameter explanations, and usage context. While conciseness is valued, here it sacrifices completeness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 3 parameters (2 required) and no output schema, the description should explain return values, parameter formats, and edge cases (e.g., invalid ranges). It does not mention what the function returns (likely a boolean) or how the 'samples' parameter affects the heuristic check. This is incomplete for an agent to use reliably.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds no meaning beyond the schema. With 0% schema description coverage, it should explain range_a, range_b (semver range format), and samples (is it inputted sample versions or generated ones?). The description only mentions 'two semver ranges' and 'sample versions' without clarifying parameter roles or formats.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: checking if two semver ranges intersect ('share any sample versions') as a conflict hint. The verb 'check' and resource 'two semver ranges' are specific, and it distinguishes from sibling semver tools like semver_satisfies (version vs range) and semver_compare (version comparison). However, it could explicitly state the output type (boolean) for full clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus its siblings. For example, it does not mention that semver_satisfies_batch checks versions against a range, or that semver_max_satisfying finds a version. This lack of contextual guidance makes it harder for an agent to choose the correct tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and limited description, the agent lacks information about the return format, error behavior, or result structure, making it incomplete for confident use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has no descriptions (0% coverage), and the tool description only adds the 'max 50' constraint without explaining the meaning of 'version', 'range', or 'id' fields, forcing reliance on common semver knowledge.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it performs batch semver range checks for dependency audits with a max of 50, distinguishing it from its sibling 'semver_satisfies' which is likely for single checks.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences with no extraneous text. Each sentence provides essential information: what the tool does and when to use it.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple sorting tool, the description covers purpose and usage context. However, it does not describe the return value (the sorted list) or error handling, which are important for the agent to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description only implicitly references the 'reverse' parameter via 'ascending or descending,' and does not explain the 'versions' array format or valid semver strings. Minimal value added beyond the schema structure.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?

The schema has 0% description coverage, so the description must compensate. It mentions the shell options but does not elaborate on the 'text' parameter or the exact meaning of the shell enum values (e.g., whether they accept aliases). Very little added value beyond the schema structure.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action 'Shell-escape' and the resource 'string', specifying the target shells (posix, powershell, cmd). It is distinct from sibling encoding/quoting tools due to its explicit shell focus.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The phrase 'When: Safely quote strings for posix/powershell/cmd' indicates when to use the tool. However, it does not provide explicit exclusions or alternatives, though no direct sibling tool exists for shell escaping.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
spdx_license_checkBInspect
Validate SPDX license expression against common license IDs.
| Name | Required | Description | Default |
|---|---|---|---|
| expression | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. The description only says 'validate' and 'against common license IDs,' but it does not specify the output format (e.g., boolean, error messages), whether it modifies anything, or how it handles invalid input. The behavioral information is minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that directly conveys the tool's purpose. It contains no redundant information and is efficiently written.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description is too sparse. It does not explain what 'common license IDs' are, how validation results are returned, or whether the tool handles complex expressions. A user would need external knowledge to fully understand the tool's behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has one parameter 'expression' with no description (0% coverage). The description adds meaning by specifying it is an 'SPDX license expression,' which clarifies the parameter's purpose. However, it does not provide examples or format constraints, leaving room for improvement.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool validates SPDX license expressions against common license IDs. The verb 'validate' and the specific resource 'SPDX license expression' make the purpose unambiguous, distinguishing it from general validation tools among siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool should be used when needing to verify an SPDX license expression, but it provides no explicit guidance on when to use it over other validation tools, nor does it mention prerequisites or alternative tools. The purpose is clear enough for basic usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
sql_danger_scanAInspect
Scan SQL text for dangerous patterns (DROP/TRUNCATE/DELETE without WHERE). Note: best-effort / heuristic — not a full language parser.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses its heuristic nature and limitation of not being a full parser. However, with no annotations, it lacks detail on additional behaviors such as whether it modifies data or requires specific permissions. The disclosure is adequate but minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with two short sentences, no redundant information, and the key caveat is front-loaded. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one input and no output schema, the description covers the core functionality and a limitation. However, it does not specify what the output looks like (e.g., list of issues, boolean), which could be helpful for completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% with only one parameter 'text'. The description adds meaning by explaining that the text should be SQL code to scan for dangerous patterns, which is sufficient for a single string parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool scans SQL text for dangerous patterns like DROP/TRUNCATE/DELETE without WHERE. It uses specific verbs and resources, and the heuristic nature distinguishes it from more comprehensive SQL tools among siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool vs alternatives like sql_format or sql_tables_extract. The mention of 'best-effort/heuristic' implies limitations but doesn't direct the agent to alternative tools for more thorough analysis.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
sql_formatAInspect
Format SQL text (never executed; reindent + keyword case).
| Name | Required | Description | Default |

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description mentions 'reindent + keyword case', which maps to parameters. However, it does not explain the effect of boolean or enum values, nor explicitly names the 'text' parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses 'Format SQL text' with a specific verb and resource, clearly distinguishing it from siblings (e.g., sql_danger_scan, sql_tables_extract) by adding 'never executed' and listing 'reindent + keyword case'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use vs alternatives. Usage is implied for SQL formatting, but no when-not-to or exclusionary hints are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
sql_tables_extractAInspect
Extract table names from SQL (FROM/JOIN/INTO/UPDATE/TABLE). When: Heuristic extract of SQL table names (best-effort).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must convey behavioral traits. It mentions 'best-effort', indicating limitations, but does not detail error handling, performance, or edge cases. This is adequate but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short and to the point, using only two sentences. It front-loads the purpose. Could be slightly improved with structure, but efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool is simple with one required parameter and no output schema, the description is minimally complete. It lacks examples or details about the return format, which would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description does not add detail about the 'text' parameter beyond implying it is SQL input. No mention of expected format, encoding, or size limits.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool extracts table names from SQL, listing specific SQL keywords (FROM/JOIN/INTO/UPDATE/TABLE). This distinguishes it from sibling tools like sql_format or sql_danger_scan, which have different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes 'When: Heuristic extract of SQL table names (best-effort).', which gives some context on when to use it (heuristic cases). However, it does not explicitly state when not to use it or mention alternatives for more robust parsing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
ssl_cert_fetchBInspect
Fetch live TLS certificate from host:port (expiry, issuer, SAN).
| Name | Required | Description | Default |
|---|---|---|---|
| host | Yes | ||
| port | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It describes a network operation ('Fetch live') but does not disclose latencies, failure modes (e.g., unreachable host, timeout), or whether it might be blocking. This is insufficient for an agent to anticipate side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single sentence conveys the core action and key outputs with no extraneous words. It is well front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description hints at return fields (expiry, issuer, SAN) but does not specify the structure (e.g., whether a full certificate object or just those fields). For a tool that likely returns structured certificate data, more detail on the output format would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It mentions 'host:port' but does not clarify that 'host' is required and 'port' defaults to 443, nor explain constraints (port range). The parameter names are self-explanatory, but additional detail would reduce ambiguity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Fetch') and resource ('live TLS certificate'), and lists key data points (expiry, issuer, SAN). It clearly distinguishes from siblings like dns_lookup (DNS records) or x509_parse (parsing a PEM string).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for retrieving current certificate details from a live host, but lacks explicit guidance on when to use vs. alternatives (e.g., x509_parse for existing certificates) or when not to use (e.g., if offline). No context on prerequisites or limitations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
string_truncateBInspect
Truncate text with ellipsis. When: Truncate long strings with ellipsis for UI/logs.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | ||
| ellipsis | No | ... | |
| max_length | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It only states the basic truncation behavior ('truncate text with ellipsis') but omits details like truncation at exact character count (max_length), handling of shorter strings, or behavior of custom ellipsis. No additional behavioral traits are disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at two sentences, with the purpose front-loaded. Every sentence earns its place, though it could be slightly more detailed without losing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, low schema coverage, and no annotations, the description is severely incomplete. It fails to explain return value (truncated string), behavior when text is shorter than max_length, edge cases, or error handling, leaving the agent under-informed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must add parameter meaning. It does not explain 'text', 'ellipsis', or 'max_length' at all, providing no value beyond the schema field names and defaults.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Truncate text with ellipsis', specifying the action (truncate) and resource (text) with ellipsis addition. It uniquely identifies the tool's purpose among siblings, as no other truncation tool exists in the list.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes 'When: Truncate long strings with ellipsis for UI/logs', providing context for usage in UI/log truncation. However, it does not explicitly mention when not to use it or compare with alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
template_fillBInspect
Fill {{variable}} placeholders in a template string.
| Name | Required | Description | Default |
|---|---|---|---|
| template | Yes | ||
| variables | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. However, it only says 'Fill {{variable}} placeholders' without explaining behavior such as whether replacement is global, case-sensitive, or what happens if a variable is missing. The description does not sufficiently inform the agent about side effects or constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, focused sentence that is concise and front-loaded. It contains no unnecessary words or fluff, making it efficient for an agent to parse.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity, the description is too sparse. It does not mention the return value (the filled string) or provide enough context for safe usage, such as handling of missing variables or special characters. An output schema is missing, so the description should fill that gap but does not.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, and the description does not adequately compensate. It implies that 'template' should contain '{{variable}}' patterns, but it does not clarify the expected format of the 'variables' object (e.g., key-value mapping) or any constraints on the parameters. The description adds minimal meaning beyond the names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: filling '{{variable}}' placeholders in a template string. It uses a specific verb ('Fill') and resource ('template string'), and the tool is distinct from all siblings, which are unrelated string utilities.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives an implied usage context (when you need to substitute variables in a template), but it does not provide explicit guidance on when to use or avoid this tool, nor does it mention any alternatives. It is minimally adequate but lacks depth.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple two-parameter tool, the description provides the essential purpose and modes. However, it omits details like return value, non-alphabetic handling, and potential limitations. Adequate but leaves gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description lists the enum values for 'mode' but does not explain each mode's transformation rules (e.g., what 'title' or 'snake' means). The 'text' parameter has no description either. Minimal added value over the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Convert case' and lists all seven modes, matching the schema enum. It distinguishes from sibling tools by the specific resource (case conversion) and the explicit modes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. The description only states what it does, not when or when not to use it.

No annotations are provided, so the description carries full burden. It only says 'wrap to a maximum line width,' but does not disclose how existing newlines are handled, whether words are broken, default behavior, or other edge cases.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no fluff. The first sentence states the purpose directly, though the second sentence is somewhat redundant. It is appropriately concise for a simple tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity and the absence of an output schema, the description should cover at least basic behavior and parameter details. It fails to mention edge cases, default width, or how the tool handles pre-existing line breaks, making it incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It mentions 'maximum line width' which hints at the width parameter, but does not explain the default (80), the units, or that text is the input. The description adds minimal value over the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Wrap text to a maximum line width,' which clearly identifies the verb and resource. It distinguishes from siblings like string_truncate, but the additional 'When:' phrase adds little new information.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description only hints at usage with 'When: Hard-wrap text to a column width.' It does not explicitly state when to use this tool versus alternatives like string_truncate or other text formatting tools, nor does it mention when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
time_convertAInspect
Convert unix seconds or ISO-8601 to both formats.
| Name | Required | Description | Default |
|---|---|---|---|
| value | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description accurately characterizes the conversion behavior without contradicting any annotations (none provided). It implies a stateless transformation, which is transparent for this kind of utility. No behavioral surprises beyond the stated purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that immediately conveys the core functionality. Every word contributes meaning, and the key information (input types, output) is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple conversion tool with one parameter and no output schema, the description is largely complete. It could benefit from clarifying the output format (e.g., an object containing both representations), but the basic idea is clear.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema provides only the parameter name 'value' with type string (0% description coverage). The description fills the gap by specifying valid inputs: 'unix seconds or ISO-8601'. This adds essential meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool converts between Unix seconds and ISO-8601, specifying both input types and the output as both formats. This distinguishes it from siblings like datetime_parse which parse arbitrary date strings, and timezone_convert which adjusts timezones.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains what the tool does but provides no guidance on when to use it versus alternatives such as datetime_parse or time_convert-like tools. With many sibling tools, explicit context for selection would be beneficial.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
time_nowBInspect
Current UTC unix timestamp and ISO-8601.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description reveals the tool returns UTC unix timestamp and ISO-8601. With no annotations, this is the only behavioral info. It lacks details on precision (seconds vs milliseconds) or output format (e.g., object or string). Acceptable but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise: two key pieces of information in a few words. No wasted text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter, no-output-schema tool, the description is minimally sufficient. However, it does not specify the output structure or whether the timestamp is in seconds. A bit more detail would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist, so the description need not add param info. Baseline score of 4 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it returns the current UTC unix timestamp and ISO-8601 string. It distinguishes itself from siblings like datetime_parse and time_convert by focusing on the current time. However, it could explicitly say 'current time' to avoid ambiguity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives. Among many time-related siblings, there is no mention of use cases or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
timezone_convertBInspect
Convert datetime between IANA timezones (e.g. UTC to Asia/Shanghai).
| Name | Required | Description | Default |
|---|---|---|---|
| value | Yes | Unix seconds or ISO datetime | |
| to_timezone | Yes | e.g. Asia/Shanghai | |
| from_timezone | No | UTC |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose behavioral traits such as input validation, error handling, or output format. The burden is on the description, which only states the basic function.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single front-loaded sentence with no wasted words. Clearly communicates the action and a concrete example, being as concise as possible.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 3 parameters, no output schema, and no annotations, the description is too brief. It fails to explain input format requirements, output structure, or error conditions, leaving the agent underinformed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 67% (value and to_timezone described, from_timezone has default only). The description adds no new parameter context beyond the example, so it meets but does not exceed the baseline for moderate coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool converts datetime between IANA timezones with a specific example, distinguishing it from sibling tools like time_convert or datetime_parse.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool vs alternatives like datetime_parse or time_convert. The name and description imply purpose but lack context for selection among many time-related siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
timezone_listAInspect
List common IANA timezone names for conversion.
| Name | Required | Description | Default |
|---|---|---|---|
No parameters | |||
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries full burden. It minimally states the action 'list' but does not disclose any behavioral traits such as whether the list is static, sorted, or if any side effects exist. For a simple listing tool this is adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no superfluous content. Every word is informative and necessary.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given zero parameters and no output schema, the description is functional but incomplete. It does not mention the output format (e.g., array of strings) or any ordering. For a list tool, some explanation of the return structure would enhance completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, so schema description coverage is 100%. The description adds no parameter-level information because none exist. Per guidelines, baseline is 3 when schema coverage is high and no param info is added.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description uses specific verb 'list' and resource 'common IANA timezone names' explicitly stating the tool's function. It clearly distinguishes from sibling tools like 'timezone_convert' which converts times, and 'timezone_now' for current time.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit instructions on when to use this tool versus alternatives. Usage is implied by the name and description, but no exclusions or contextual triggers are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
todo_comment_extractCInspect
Extract TODO/FIXME/HACK/XXX comments with line numbers.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description must disclose behavioral traits. It mentions line numbers but omits output format, case sensitivity, multi-line handling, and whether extraction is regex-based or exact match. This is insufficient for an agent to invoke reliably.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that conveys the core action efficiently. However, it could be slightly more structured (e.g., bullet points) without losing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description must explain return values. It mentions line numbers but not the format (list, object, string) or whether results are sorted. This leaves critical gaps for an agent expecting structured output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The sole parameter 'text' has 0% schema description coverage. The description adds no specifics about the expected input format or constraints (e.g., encoding, size limits). It does not compensate for the lack of schema documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (extract), the specific comment types (TODO/FIXME/HACK/XXX), and that line numbers are included. This distinguishes it from other sibling extraction tools like extract_emails or extract_urls.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. It does not mention prerequisites, exclusions, or context for use, leaving the agent to infer appropriateness.

toml_schema_validateBInspect
Validate TOML config against JSON Schema (Draft 7) in one step.
| Name | Required | Description | Default |
|---|---|---|---|
| toml | Yes | TOML document text | |
| schema | Yes | JSON Schema (Draft 7) | |
| max_errors | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only states the action and does not reveal what happens on validation failure, how errors are reported, the effect of the max_errors parameter, or any side effects. The description is insufficient for an agent to understand the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is concise and front-loaded with the action verb 'Validate'. It contains no fluff and every word serves a purpose. It efficiently conveys the core function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool complexity (validating TOML against JSON Schema with a configurable error limit) and the lack of output schema, the description is too brief. It omits important details like return format, the meaning of max_errors, and how validation errors are presented. A more complete description would cover these aspects.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 67% (2 of 3 parameters have descriptions in the schema). The description does not add any additional context to the parameters; it merely repeats the general purpose. Since coverage is below 80%, the description should compensate but does not. The max_errors parameter is not mentioned at all.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Validate' and specifies the resource: 'TOML config against JSON Schema (Draft 7) in one step.' It distinguishes from sibling tools like toml_validate (which likely validates only TOML syntax) and json_schema_validate (which validates JSON against schema). This provides a specific and actionable purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description lacks any guidance on when to use this tool versus alternatives or when not to use it. It does not mention that users could separately validate TOML syntax with toml_validate and then apply json_schema_validate. The one-step nature is implied but no explicit usage context is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
toml_to_jsonBInspect
Parse TOML and return JSON-compatible object.
| Name | Required | Description | Default |

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and description lacks behavioral details such as error handling, performance, or side effects. Only states basic purpose.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, direct and clear. Could be more structured but efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema and minimal description leave questions about return format, error handling, size limits. Incomplete for a simple conversion tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Single parameter 'text' is self-explanatory, but description adds no additional meaning beyond schema. Schema description coverage is 0%, so description should compensate, but it doesn't.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb (Parse), resource (TOML), and output (JSON-compatible object). Distinguishes from sibling conversion tools like json_to_toml, yaml_to_json, etc.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use vs alternatives. Usage is implied by the conversion nature, but no when-not or alternative tools mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
toml_validateAInspect
Validate TOML text; return parsed object or error.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It clearly states the core behavior: validating TOML text and returning either a parsed object (success) or an error (failure). This adequately conveys that the tool is non-destructive and returns a standard result, though it could mention that the operation is stateless and has no side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise at 9 words, yet covers the essential purpose and outcome. It has no unnecessary information, but for a tool with a single parameter, slightly more detail (e.g., what constitutes a valid TOML file) would not hurt conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool (one required parameter, no output schema), the description covers the main functionality. However, it lacks information about the error format or the structure of the parsed object, which might be needed for integration. It is minimally viable but leaves some ambiguity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter, 'text', is described only by its name. The description does not add any additional context such as expected TOML format version, character encoding, or constraints. With 0% schema description coverage, the description fails to compensate for the lack of detail in the input schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Validate' and resource 'TOML text', and specifies the outcome ('return parsed object or error'). It effectively distinguishes from sibling tools like toml_schema_validate (schema validation) and toml_to_json (conversion), making the tool's purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives such as json_validate, yaml_validate, or toml_schema_validate. It does not mention that this is for syntax validation only, nor does it direct users to other tools for schema or format conversion.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
trailing_whitespace_scanAInspect
Scan text for trailing whitespace and tab characters. Note: best-effort / heuristic — not a full language parser.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
While no annotations are provided, the description adds the heuristic/best-effort note, indicating limitations. However, it does not describe what the output looks like or any other behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise, front-loaded sentences. Every word adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple scan tool with one parameter and no output schema, the description covers the core functionality and limitations. Some missing detail on output format, but adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single text parameter is obvious from the context, but the description adds no additional meaning beyond the schema. Baseline score applies given schema coverage is 0% but parameter is self-explanatory.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool scans text for trailing whitespace and tab characters, using a specific verb and resource. It distinguishes itself from sibling tools by its narrow focus.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives among the many sibling tools. Lack of context about when it is appropriate or not.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
tsconfig_lintBInspect
Lint tsconfig.json structure (compilerOptions, strict hints).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. 'Lint' suggests read-only checking, but does not explicitly state whether it modifies anything, what side effects occur, or whether it requires network access. Behavioral traits are underspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, no unnecessary words. Information is front-loaded and efficiently delivered.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema and no description of return values. For a linter, the output format (e.g., list of errors/warnings) is crucial but omitted. Incomplete for a tool with single parameter and no sibling differentiation beyond purpose.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage 0% and only one parameter 'text' (string). Description only mentions 'tsconfig.json structure' and 'compilerOptions, strict hints', but does not clarify that 'text' should be the raw JSON content. Adds minimal meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the tool lints tsconfig.json structure, specifically compilerOptions and strict hints. Verb 'lint' and resource 'tsconfig.json' are specific. Among sibling lint tools, it uniquely targets TypeScript config.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implies usage when you need to check a tsconfig.json, but does not provide explicit when-to-use or when-not-to-use guidance, nor alternatives. Lacks context for exclusion or comparison with other lint tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

With no annotations, the description carries full burden but only repeats the tool's name. It does not disclose what normalization does, side effects, invalid input handling, or return format.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely short (one phrase) but under-specified, not conciseness. Every sentence should add value; this one barely adds beyond the name.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, output schema, or schema descriptions, the tool description fails to provide the necessary behavioral and contextual information for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description adds no parameter explanations. It lists the enum values but doesn't differentiate them or describe the 'text' parameter.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs Unicode normalization and lists the four normalization forms (NFC, NFD, NFKC, NFKD), distinguishing it from sibling encoding/decoding tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs siblings or which normalization form to choose. The description lacks context for appropriate usage scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
unified_diff_parseCInspect
Parse unified diff — files changed, lines added/removed.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavior. It describes core functionality but omits details like input format requirements, error handling, and the structure of the parsed output. As a parse tool with no output schema, the agent lacks critical behavioral information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise (one sentence), but it lacks structural elements like usage notes or examples. While it front-loads the verb, the brevity sacrifices clarity for a tool that parses a specific format.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool that parses a non-trivial format (unified diff), the description is severely incomplete. No output schema, no input format details, and no error handling information. The agent cannot reliably use this tool based solely on the description.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'text' has 0% schema description coverage and no extra explanation in the tool description. The agent is given no additional meaning, such as expected format (e.g., 'must be valid unified diff text') or encoding hints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's action ('Parse') and resource ('unified diff'), and mentions specific outputs ('files changed, lines added/removed'). It differentiates from the sibling 'text_diff' which computes diffs rather than parsing them.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, such as 'text_diff'. There is no mention of prerequisites or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
unit_convertCInspect

| category | No | optional: length, weight, temperature, data, speed, time | |
| from_unit | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It does not mention whether the operation is read-only, error handling, or constraints like unit format validity. Simply stating 'Convert units' is insufficient for an agent to anticipate behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that efficiently conveys the tool's purpose. Every word is necessary, and it avoids redundancy. It could be slightly more structured by separating categories, but overall it is concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, no annotations, and low schema coverage, the description is severely incomplete. It fails to explain the output format, error cases, or supported unit range. The agent would likely need additional context or trial-and-error to use this tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With only 25% schema description coverage (only the 'category' field has a description), the description adds minimal meaning. It lists categories but does not clarify the format or accepted values for 'from_unit' and 'to_unit' (e.g., case sensitivity, abbreviation vs. full name). This gap leaves the agent underinformed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool converts units and lists six categories (length, weight, temperature, data, speed, time), distinguishing it from sibling tools like currency_convert and time_convert. However, it could be more specific about the scope (e.g., 'Convert physical quantities between units').
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. With many conversion siblings (e.g., currency_convert, time_convert), the description should explicitly state that currency and time are not covered (since time_convert exists) and mention that unit_list provides supported units. The lack of such context hinders correct selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

No annotations are provided, so the description must cover transparency. It indicates a read-only list operation, which is likely safe. However, it does not elaborate on output format or error conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single clear sentence with no filler, front-loading the purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description is minimal. It does not specify the structure of the output (e.g., mapping of categories to units). For a simple tool it may suffice, but lacks full context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, and the schema has 100% coverage (empty). The description adds the context of 'per category', which is helpful but not required. Baseline 4 for 0 params.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It discloses three normalization behaviors (lowercase host, sort query, drop fragment) but omits other potential behaviors such as handling of invalid URLs, default port removal, or encoding normalization. The description is minimal and leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short and front-loaded, using a single sentence with parenthetical details. Every word serves a purpose, though it could be slightly more structured to list actions clearly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (3 parameters, no output schema, no annotations), the description is incomplete. It does not mention the return value (the normalized URL string), error handling for invalid URLs, or edge cases. The description covers only the basic normalization steps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It mentions 'sort query' and 'drop fragment' which map to two parameters, but does not explain their defaults or the semantics of the required 'url' parameter. The description adds minimal value beyond parameter names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden for behavioral disclosure. It only lists categories checked but does not explain whether the tool fetches the URL, how it validates, or what the output format is. This is insufficient for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no fluff. Every word is essential, achieving maximum conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool without output schema or annotations, the description is adequate but lacks details on return type or behavior. It covers the core purpose but leaves gaps in expected output and usage conditions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% for the single 'url' parameter, so description must compensate. It adds context that the URL will be checked for SSRF risks, but does not specify required format (e.g., protocol, encoding). A 3 is appropriate as some meaning is added.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool checks a URL for SSRF risk, specifically naming localhost, private IP, and metadata hosts. This verb+resource combination distinguishes it from sibling tools like url_parse or ipv4_private_check.

The description mentions a specific behavior (attributes as @attr) but does not disclose other important traits such as input validation, error handling, or handling of namespaces, CDATA, or comments. For a straightforward conversion tool, this is adequate but lacks detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is exceptionally concise with two sentences. The first sentence clearly states the core functionality, and the second adds a usage guideline. No unnecessary words or fluff. Well-structured and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Considering the tool has only one parameter, no output schema, and no annotations, the description covers the essential purpose and usage context. It does not detail output format, error conditions, or limitations, but for a simple conversion tool this is fairly complete. The sibling tools also support the context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has one parameter 'text' with 0% description coverage. The description does not add any additional meaning or constraints to the parameter beyond the schema. Since coverage is low, the description should compensate but fails to do so, leaving the parameter's expected format and semantics ambiguous.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Convert XML document to JSON (attributes as @attr).' It specifies the action (convert), the source format (XML), target format (JSON), and a key detail about attribute handling. This distinguishes it well from sibling conversion tools like csv_to_json, yaml_to_json, etc.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description includes a 'When: Convert XML → JSON for agents that prefer JSON tools.' This provides clear guidance on when to use the tool, but does not explicitly mention when not to use it or provide alternatives. The context is sufficient but could be more comprehensive.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
xml_validateCInspect
Validate XML markup (well-formed check).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It only states 'well-formed check', implying read-only operation, but does not disclose return format, error handling, or side effects. Lacks sufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is one sentence, very concise. However, this brevity sacrifices critical details that could be added without much verbosity (e.g., what the tool returns). It is appropriately short but under-informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and simple input, the description should explain return value (boolean, error list, etc.) and behavioral aspects. It only covers purpose, leaving agents without necessary context to use the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, and the description does not clarify the 'text' parameter beyond the schema's type. The description mentions XML markup but does not explicitly map to the parameter or specify constraints (e.g., encoding, size limits).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb (validate) and resource (XML markup), with a specific scope (well-formed check). It distinguishes from sibling XML tools like xml_format (formatting) and xml_to_json (conversion).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives (e.g., json_validate, yaml_validate). No mention of prerequisites, limitations (e.g., no schema validation), or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
yaml_schema_validateBInspect
Parse YAML then validate against JSON Schema (Draft 7).
| Name | Required | Description | Default |
|---|---|---|---|
| yaml | Yes | ||
| schema | Yes | ||
| max_errors | No |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the two-step process (parse then validate) and the schema version (Draft 7). However, it does not describe the output format (e.g., errors vs success), failure behavior, or any limitations beyond Draft 7. With no annotations, this is minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single sentence that is concise and front-loaded with the core purpose. No wasted words; every word adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's two-step complexity, no output schema, and lack of parameter descriptions, the description is incomplete. It fails to specify return value (e.g., validation result), how max_errors affects output, or the relationship between parsing and validation steps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides parameter names only (0% description coverage). The description does not explain what each parameter expects (e.g., 'yaml' as YAML string, 'schema' as JSON Schema string) or the role of 'max_errors'. The only added value is noting Draft 7 for the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (Parse YAML then validate) and the resource (YAML against JSON Schema Draft 7). It distinguishes from siblings like yaml_validate (syntax only) and json_schema_validate (JSON input) by combining both steps.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage context (when you have YAML and need JSON Schema validation) but does not explicitly state when not to use it or mention alternatives. It lacks guidance on which sibling tool to choose for different use cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
yaml_to_jsonCInspect
Parse YAML and return JSON-compatible object.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must fully disclose behavior. It only mentions parsing and returning an object, but not error handling, output format details, or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence (7 words) is very concise but at the expense of necessary details. Could be restructured to include more information without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 1-param tool with no output schema or annotations, the description lacks details on input expectations, error conditions, and return value structure, making it incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% and description does not add meaning beyond implying 'text' is YAML content. No format or constraints specified.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool parses YAML and returns a JSON-compatible object. It differentiates from siblings like yaml_validate or json_to_yaml, though not explicitly.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives like yaml_validate or json_to_yaml. No context or prerequisites mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
yaml_validateBInspect
Validate YAML text; return parsed object or error.
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes |
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries full burden for behavioral disclosure. It only states it returns parsed object or error, but lacks details on error types, handling of malformed YAML, idempotency, or any side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence with no extraneous words. It conveys the core action and output efficiently, though it could be slightly more structured with bullets for readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple input and no output schema, the description is adequate but incomplete. It does not specify YAML version support or distinguish from sibling tools that also parse YAML, leaving some ambiguity for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description adds no meaning beyond the parameter name 'text'. It simply says 'Validate YAML text', which does not elaborate on what valid inputs look like, encoding, or length constraints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Validate', the resource 'YAML text', and the outcome 'return parsed object or error'. This distinguishes it from siblings that only validate schema or convert formats, as it returns the parsed object itself.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like yaml_to_json or yaml_schema_validate. It does not include any when-to-use or when-not-to-use instructions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
