Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v1.0.0
Disambiguation5/5
Each tool has a clearly distinct purpose, even among related utilities like regex explain vs test or hash vs hmac. The descriptions sufficiently differentiate similar-sounding tools.
Naming Consistency3/5
Tool names mix verb-first (explain_regex, generate_uuid), noun-first (json_diff, http_status), and single nouns/verbs (hash, encode, hmac), breaking a consistent pattern. However, all use snake_case and are descriptive, so they remain readable.
Tool Count2/5
With 37 tools, this exceeds the 25+ threshold for 'too many' per the rubric. While each tool has a distinct function, the sheer number may overwhelm agents and increase selection difficulty.
Completeness4/5
The server covers a wide range of developer utilities—text, regex, data formats, datetime, validation, generation, and Markdown. Minor gaps exist (e.g., no XML handling or URL encoding-specific tool), but core utility coverage is strong.
Average 3.4/5 across 37 of 37 tools scored. Lowest: 2.7/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, description is the sole source of behavioral info. It states the tool returns current time but does not disclose output format, return type, or timezone validation. The mention of 'various format options' is misleading since no format parameter exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence and front-loads the core purpose. It is concise, though it sacrifices necessary detail for brevity, which is acceptable given the short form.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
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 and no annotations, the description should explain return format, timezone handling, and format options. It only gives a high-level statement, leaving the agent without enough information to predict behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already covers the timezone parameter with examples, so the description adds little value. The reference to 'format options' implies parameters that do not exist in the schema, creating confusion rather than clarity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly identifies the tool as retrieving the current time for any timezone, which distinguishes it from sibling tools like datetime_diff. However, 'various format options' is vague and unsubstantiated by the schema, leaving ambiguity about output behavior.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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, and no exclusions or prerequisites are mentioned. The description implies usage but does not explicitly state it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the basic function without revealing output format, randomness, or that it is configurable via type and count.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence with no wasted words. It is appropriately sized for a simple tool, though it could be more informative without losing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simplicity of the tool, the description omits key context like the return format. With no output schema, the description should at least hint at what the output looks like, but it does not.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
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 mention the 'type' or 'count' parameters. It fails to compensate for the lack of schema descriptions, though the schema itself provides clear names and an enum.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Generate') and resource ('lorem ipsum placeholder text'), clearly distinguishing it from sibling tools like generate_password or generate_fake_data. It is not a tautology and conveys exactly what the tool does.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. There is no mention of exclusions, context, or when a different tool would be more appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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, but it only states the action. It does not disclose what the tool returns (e.g., a formatted string), whether it validates SQL syntax, how it handles different dialects, or any error behavior. This leaves significant ambiguity for an 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence that front-loads the purpose with no redundant or vague wording. Every word earns its place, making it exemplary in conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 3 parameters, no annotations, and no output schema, the description is too sparse. It omits critical context such as the return value, behavior on invalid SQL, and how the dialect parameter alters output. This gap in contextual information makes the tool description incomplete for an agent to invoke it confidently.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema describes 'sql' and 'dialect' (67% coverage), and the description adds no additional parameter meaning. However, the existing schema descriptions are adequate, and 'indent' is self-explanatory from its name and default value. The description doesn't compensate for the missing 'indent' description, but the overall parameter understanding is acceptable.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('format and pretty-print') and the resource ('SQL queries'), which makes the tool's purpose immediately understandable. It implicitly distinguishes from sibling tools like format_json and analyze_sql by focusing specifically on SQL formatting, though it doesn't explicitly name alternatives.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidance is provided. The description only states what the tool does, with no mention of when to use it, when not to use it, or how it compares to alternatives such as analyze_sql or format_json. The usage context is left entirely to inference.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits, but it only says 'realistic fake data.' It fails to mention reproducibility via seed, count limits, randomness, or output format. This leaves significant behavioral uncertainty.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence with no unnecessary words. However, the trailing 'etc.' is vague and could be more specific by listing all available categories.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and no annotations, the description should explain return values and edge cases. It doesn't mention the response structure, error behavior, or how count affects results, leaving the tool under-specified for an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema provides descriptions for 2 of 3 parameters (type and seed), covering 67%. The description adds some value by aligning 'people, addresses, companies' with the type enum, but it doesn't mention seed or count, so it only partially compensates for the schema gaps.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: generating realistic fake data for testing, with examples of categories. It distinguishes from more specific generators like generate_password or generate_uuid by being broader, though it doesn't explicitly name sibling alternatives.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 says 'for testing' but doesn't explain exclusions or contrast with related generators. Users must infer usage from the description alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description claims the tool can generate ULID identifiers, but the input schema only allows version values '4' and '7' with no option for ULID. This mismatch overstates the tool's capabilities. It also does not disclose default behavior (count=1, version='4') or the 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence with no unnecessary words. However, it omits important behavioral details and includes a misleading ULID reference, which detracts from its value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with two optional parameters and no output schema, the description is insufficient. It fails to specify the return format, clarify the ULID discrepancy, or provide usage context, making it inadequate 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.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema covers both parameters thoroughly with descriptions for count and version, so the description adds no parameter-specific value. The mention of ULID may confuse the version parameter, but the schema already provides sufficient semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses the specific verb 'Generate' and clearly identifies the resource as 'UUID (v4 or v7) or ULID identifiers', distinguishing it from sibling generation tools like generate_password or generate_qr. The inclusion of ULID is misleading given the schema, but it does not obscure the core purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 use cases like creating unique identifiers for databases, nor does it contrast with generate_password or other generation tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 mentions hashing text and algorithms but does not state output format (e.g., hex-encoded string), behavior for edge cases, or that it is a pure read-only operation. Minimal detail beyond the core action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no filler. It efficiently communicates the core purpose, though it is sparse on details like output format.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
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 clarify what the tool returns (e.g., hex digest). It also mentions 'or other algorithms' which is not reflected in the enum, potentially misleading the agent. For a simple hash utility, the description is notably incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with descriptions for both 'text' and 'algorithm'. The description's mention of MD5, SHA-1, etc., largely repeats enum values and adds little beyond them. The phrase 'or other algorithms' may even imply a broader set than the schema allows, which could confuse.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: 'Hash text' with a list of algorithms. It is specific about the verb and resource, but it does not explicitly distinguish from sibling tools like hmac (keyed hash) or encode (encoding).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 hmac or encode. The description only states what it does, implying usage but offering no exclusions, prerequisites, or contextual cues.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 only states the action but does not describe the output format, whether nested headings are included, how the TOC is structured, or any edge-case behavior. This leaves the agent uncertain about the return value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence with no wasted words. It is appropriately short for a tool with one parameter, though it omits useful output details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given there is no output schema, the description must explain what the tool returns. It does not, leaving the result type and structure ambiguous. For a tool with one input, this is a significant gap in completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema describes the only parameter 'markdown' as 'Markdown text' (100% coverage). The description adds no additional meaning beyond that, so the baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool extracts a table of contents from a Markdown document. It uses a specific verb ('Extract') and resource ('table of contents'), making it distinct from siblings like markdown_to_html or extract_from_text.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided about when to use this tool versus alternatives. It does not mention any prerequisites, exclusions, or compare with other tools that might handle Markdown content.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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, but it only states the basic operation. It does not disclose the output format (e.g., hex vs base64), determinism, or that it is a pure function with no side effects. This is a significant gap for a security-related tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that front-loads the core purpose. It contains no fluff or redundancy, making it easy to parse and understand quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
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 is responsible for explaining the return value, but it only says 'Generate HMAC signature' without specifying the format or encoding. It also omits any mention of algorithm selection or error conditions, making it incomplete for an agent to predict the full behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description repeats the schema's parameter names ('text' and 'secret key') without adding new meaning. It does not elaborate on the 'algorithm' parameter, which is only partially covered by the schema (enum default). The description adds no guidance on parameter formats or valid values.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function with a specific verb ('Generate'), a distinct resource ('HMAC signature'), and context ('for text with a secret key'). This distinguishes it from siblings like 'hash' or 'encode', which serve different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 vs. alternatives. It does not mention that HMAC is for authenticated messages, nor does it contrast with general hashing or encoding tools. The intended use case is implied but never explicitly stated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosure. It simply says 'see matches' without describing how matches are returned (e.g., full match vs. groups, positions, or count), how flags affect behavior, or what happens with invalid patterns. It does not even explicitly state that the operation is read-only and safe.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that immediately communicates the core action. Every word is useful and there is no redundant or boilerplate content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple test tool with full schema coverage, the description is minimally adequate, but it lacks details about the return value structure and any usage context. Since there is no output schema, the description could have explained what 'see matches' entails (e.g., an array of match objects). The absence of such information makes it only partially complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with each parameter (pattern, text, flags) already explained. The tool description adds little beyond restating that it tests a regex against text, so it neither enhances nor detracts from the schema-provided semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a clear verb 'Test' with a specific resource 'regular expression against text' and indicates the outcome 'see matches'. However, it does not explicitly distinguish the tool from sibling tools like 'extract_from_text' which might also work with regex expressions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 'explain_regex' for understanding a pattern or 'extract_from_text' for using regex to pull data. The only implicit usage is testing a regex, but no exclusions or contextual scenarios are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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, but it only states the core transformation. It omits important traits such as error handling for invalid YAML, output formatting (e.g., compact vs. pretty), and whether the result is a string or object.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence with no wasted words. It is appropriately sized for a simple conversion tool, though it largely restates the tool's name.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of annotations and an output schema, the description is too minimal to be fully useful. It does not explain expected return values, error conditions, or edge cases, leaving the agent without enough context for robust invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has a single parameter 'yaml' with description 'YAML text', achieving 100% schema coverage. The description adds no additional meaning beyond the schema, so the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Convert YAML to JSON' uses a specific verb and resource, clearly stating the tool's function. It inherently distinguishes from siblings like json_to_yaml by specifying the transformation direction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 json_to_yaml or csv_to_json. The description simply states the conversion with no context, prerequisites, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 lists what is counted but not how counts are performed (e.g., whitespace tokenization, whether characters include spaces, or reading speed assumption). This leaves ambiguity about the exact output.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is front-loaded with the primary action and lists all output categories. It is free of unnecessary words or repetition, making it maximally concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and no annotations, the description should indicate what the tool returns (e.g., a JSON object with word_count, char_count, etc.) and any relevant counting rules. It does not, leaving the agent without critical information for interpreting results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The only parameter 'text' is fully documented in the schema as 'Text to analyze', giving 100% coverage. The description reiterates the tool's purpose but adds no additional input-format constraints, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description is clear and specific: 'Count words, characters, sentences, and estimate reading time' names the exact resources and actions. It distinguishes itself from sibling tools like slugify or convert_case, which perform transformations rather than analyses.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
There is no guidance on when to use this tool versus alternatives. It does not mention any exclusions, prerequisites, or context where another sibling tool (e.g., extract_from_text) might be more suitable.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 only states 'calculate the difference' without detailing timezone handling, input validation behavior, error cases, or the exact return format. For a computation tool, this lacks the transparency needed to anticipate unexpected behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence that immediately conveys the tool's purpose. It is front-loaded with the verb and resource, contains no fluff, and every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
This simple tool has no output schema, so the description should explain what the difference looks like (e.g., units, format). It does not, leaving the agent to guess whether the result is in seconds, days, or a human-readable string. The two parameters are well-defined in the schema, but the missing return-value documentation makes the description incomplete for an agent to confidently use the tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already describes both parameters ('from' and 'to') with 100% coverage, so the description does not need to add much. It does say 'between two dates/times', which aligns with the parameters but adds no new semantic detail beyond the schema. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('calculate') and the resource ('difference between two dates/times'), which is specific and unambiguous. It naturally distinguishes itself from sibling tools like datetime_now by focusing on the subtraction operation, so the agent knows exactly what the tool is for.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. It does not mention any exclusions, prerequisites, or alternative tools, leaving the agent to infer usage solely from the name and description. This is a clear gap given the many sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full burden of behavioral disclosure. It only states the basic encode/decode function, without addressing how HTML entity encoding treats special characters, behavior on invalid input, or whether encoding is fully reversible. This leaves the agent unaware of 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, tightly worded sentence that efficiently conveys the core function and supported formats. There is no redundancy or filler, exemplifying concise and structured communication.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
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 and no annotations, the description is too thin. It fails to mention the return value format, potential error conditions, or any broader usage context, leaving critical information absent for an agent to invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides descriptions for all three parameters, achieving 100% coverage. The description adds no additional semantic value beyond what the schema already states, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function as 'Encode/decode text' and specifies the exact formats supported (base64, URL, hex, HTML entity encoding). This distinguishes it from sibling tools like hash or hmac, which perform one-way cryptographic operations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description offers no guidance on when to use this tool versus alternatives, nor does it mention any exclusions or prerequisites. The agent is left to infer from the tool name and sibling list, which is insufficient for effective selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 behavior such as error handling, handling of invalid SQL, output format, or limitations. It only lists what is extracted.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that clearly states the tool's function without unnecessary words. Every element serves a purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with one parameter, and the description conveys the core functionality. However, it lacks details on behavioral aspects (e.g., does it parse complex queries? Does it return errors?) and there is no output schema, limiting completeness for a fully effective tool description.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and the parameter 'sql' is documented in the schema. The description adds context about what is extracted but does not elaborate on parameter format or constraints beyond the schema. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses the specific verb 'Extract' and clearly states the resource (SQL query) and the extracted elements (tables, columns, JOINs, structure). It distinguishes this tool from siblings like format_sql (formatting) and extract_from_text (generic text extraction).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 over alternatives, and no exclusions or alternative tool mentions. The usage is only implied from the description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It simply states the purpose without disclosing the return format, behavior on invalid regex, or whether flags are supported. The description gives no behavioral context beyond the action itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no wasted words. It is front-loaded with the verb and resource, and effectively communicates the tool's purpose in a concise manner.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Although the tool is simple with one parameter, there is no output schema and the description does not specify what the explanation looks like (e.g., string, list, natural language sentences). For a tool that explains regex, some detail about 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.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents the 'pattern' parameter as 'Regex pattern to explain'. The description adds no additional syntax or format details, making a baseline score of 3 appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'explain' with a clear resource 'regular expression' and specifies the output format 'in plain English'. It distinguishes itself from sibling tools like test_regex which tests regex behavior.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives no guidance on when to use this tool versus alternatives. It does not mention when not to use it or provide any context about choosing this over sibling tools like test_regex or extract_from_text.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry behavioral disclosure, but it only states 'secure random' without specifying return format, cryptographic randomness, statelessness, or how the 'type' and 'length' parameters interact. This is insufficient for an agent to predict behavior beyond the basic operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no wasted words. Every token contributes meaning, making it highly concise and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple, but without an output schema or annotations, the description leaves out useful context such as the return format (e.g., a plain string) and when to prefer it over siblings like generate_fake_data. It is adequate for basic use but has clear gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already describes 'length' clearly and provides self-explanatory enum values for 'type', so the description adds little. It mentions passwords and passphrases but omits 'pin', and does not explain parameter syntax or constraints beyond the schema. With 50% schema coverage, the description only partially compensates, earning a middle score.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Generate') and resource ('secure random passwords or passphrases'), clearly distinguishing it from sibling tools like generate_uuid or generate_lorem. The only minor gap is omitting the 'pin' type from the schema, but the core purpose is unmistakable.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 instead of alternatives, nor any exclusions or prerequisites. The phrase 'secure random' hints at security-sensitive contexts, but no explicit when/when-not guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It only states the general transformation but does not disclose expected behaviors like lowercasing, character replacement rules, or handling of non-ASCII characters. This leaves critical ambiguities for an agent deciding on output.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no wasted words. It conveys the essential purpose efficiently and is appropriately sized for a simple utility.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with one parameter and no output schema, so the description and schema are largely adequate. However, lacking behavioral details (e.g., case normalization, character handling) makes it incomplete for an agent that needs to predict exact output, especially since no annotations exist to fill gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage for the single 'text' parameter ('Text to slugify'). The description adds the context of 'URL-safe' but does not provide additional detail beyond what the schema already states, so it meets the baseline.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Convert text to a URL-safe slug' uses a specific verb and resource, clearly stating the tool's function. It distinguishes from siblings because no other tool mentions slugification, and the term 'slug' is unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 vs alternatives, nor any exclusions or prerequisites. While the purpose is clear, the description does not explicitly state context or mention alternatives such as convert_case or encode.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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, but it only states the basic conversion action. It does not explain how input text is parsed, how edge cases are handled, or what 'and more' includes, leaving significant behavioral ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, front-loaded with the action verb, and lists formats efficiently. Every word serves a purpose, with 'and more' compactly covering the remaining schema enum values without unnecessary repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with two required parameters and no output schema, the description adequately conveys the core purpose and supported formats. However, it omits details about return type and how the tool handles ambiguous or mixed-case input, which are minor gaps given the tool's simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with both parameters described, so the baseline is 3. The description restates some enum values as human-readable case names but adds no additional semantics beyond what the schema already provides for the 'text' and 'to' parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'Convert text between' with a specific list of case formats, making the tool's purpose unmistakable. The verb 'convert' and resource 'text' are clear, and the enumerated formats distinguish it from sibling tools like encode or slugify.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives no guidance on when to use this tool versus alternatives, nor does it mention any context or exclusions. It only implies usage by listing conversion formats, which is not enough for an agent to decide between this and related tools like slugify.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions returning base64 PNG or SVG, but omits the 'terminal' format available in the schema, providing incomplete and slightly misleading information about output behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is front-loaded with the core action and includes essential input/output details. There is no wasted wording.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
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 and no annotations, the description should explain all return possibilities and any relevant behavior. It fails to mention the 'terminal' format and provides no info about error handling or size constraints, leaving important gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the parameters are already well-described. The description adds minimal value beyond the schema, though it does clarify that 'base64' likely refers to a PNG image, which is helpful for interpreting the format enum.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Generate a QR code'), the resource ('QR code'), and the input ('from text or URL'). It even mentions output formats, making the tool's purpose unmistakable and distinguishing it from any sibling tool.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage by stating the input and output, but it does not explicitly specify when to use this tool versus alternatives, nor does it mention any exclusions or prerequisites. With no sibling QR tool, some guidance is implied but not articulated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavior disclosure. It only states the conversion itself, adding no context about output format, error handling, markdown features supported, or side effects. The description is essentially the same as the tool name, providing no additional transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence with no filler. It is front-loaded with the action and resource, making it immediately clear and appropriately sized for a simple conversion tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter converter with no output schema, the description is almost complete: it states the input (Markdown) and the result (HTML). However, it lacks any mention of edge cases or behavior details, though these are less critical given the tool's simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% (the 'markdown' parameter is described as 'Markdown text'). The description adds no extra parameter information, but the schema already fully documents the input. This meets the baseline of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Convert') and resource ('Markdown to HTML'), clearly stating the tool's function. It distinguishes from sibling tools like csv_to_json or yaml_to_json by specifying the exact format transformation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. There is no mention of context, exclusions, or comparisons to related tools (e.g., other format converters). The description simply states the conversion without any usage direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden for behavioral disclosure. 'Generate color palettes' implies a non-destructive operation but gives no details about return format, side effects, or constraints. It does not disclose what a palette looks like (e.g., array of hex codes, number of colors) or any dependencies, leaving significant gaps 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, front-loaded with the action verb and listing relevant palette types. Every word earns its place; there is no fluff or repetition. 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.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description should clarify what the tool returns, but it does not. The tool is low-complexity (2 params), yet an agent would not know whether the output is a list of hex codes, a count, or an object. The description is too sparse to be considered complete for safe invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema already describes the 'color' parameter well (hex or CSS name) and lists the 'type' enum. The description merely echoes some enum values ('complementary, analogous, triadic') without adding meaning beyond what the schema provides. It does not explain what each palette type produces or add any new details about parameter usage, so it adds minimal value over the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function with a specific verb and resource: 'Generate color palettes'. It lists several palette types (complementary, analogous, triadic, split-complementary) which distinguishes it from sibling tools like check_contrast, which is about contrast checking. This makes it unambiguous what the tool does.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for generating color palettes, providing clear context without explicit exclusions or alternatives. While no alternative is named, the purpose is specific enough that an agent would know when to choose this tool over other utility tools. It lacks a 'when not to use' note but is otherwise clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 states the output is a unified diff but doesn't explain details such as line-by-line comparison, handling of whitespace, or what happens with identical texts. This is minimal for a tool with no annotation support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that directly states the tool's purpose without any redundant information. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with two string parameters, and the description conveys its core purpose. However, without an output schema or annotations, the lack of detail about the diff format (e.g., context lines, exit behavior) leaves some ambiguity for an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already describes both parameters ('Original text' and 'Modified text') providing 100% coverage. The description adds no additional parameter-level detail, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool compares two texts and produces a unified diff. The verb 'compare' and resource 'two texts' are specific, and 'unified diff' distinguishes it from sibling tools like json_diff, which targets JSON specifically.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description gives no explicit guidance on when to use this tool over alternatives like json_diff. The context is implied: use it for any text comparison, but no exclusions or prerequisite conditions are provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the extraction scope but fails to mention return format (e.g., array of matches), behavior on multiple/no matches, or whether extraction is case-insensitive or deduplicated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that lists the core functionality and entity types without any wasted words, making it immediately scannable.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple two-parameter extractor, the description covers the input semantics but omits the return shape, which is especially important since no output schema is provided. The missing output details leave some ambiguity for an agent consuming the result.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%: both 'text' and 'type' have explicit descriptions and the enum lists all allowed values. The description adds minimal value beyond the schema, merely mapping 'phones' to 'phone numbers' and restating the entity types.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Extract') and explicitly enumerates the target entity types (emails, URLs, numbers, hashtags, mentions, phone numbers), clearly distinguishing the tool from siblings like test_regex and extract_markdown_toc.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use the tool—whenever you need to extract these entity types from text—but it does not explicitly mention alternatives, prerequisites, or when-not-to-use conditions relative to sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the actions but does not disclose return format, error handling for invalid JSON, or any side effects, leaving significant ambiguity for a validation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, immediately front-loaded with the core purpose, and contains no filler or redundant words. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
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 names the core operations and the schema covers parameters. However, with no annotations or output schema, the lack of return type and error behavior leaves the description incomplete for validation use-cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema provides 100% parameter coverage with descriptions for both json and indent, so the baseline is 3. The description adds no additional parameter-level meaning beyond what the schema already contains.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses specific verbs (format, validate, pretty-print) with the resource (JSON), clearly stating the tool's purpose. It distinguishes from sibling tools like json_diff and json_query, which operate on JSON differently.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage is implied by the action verbs: use when you need to format, validate, or pretty-print JSON. However, there is no explicit guidance about when to prefer this over alternatives or any exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 only says 'compare' and 'show differences', but does not specify whether the comparison is deep, how key ordering is handled, or what the output format looks like. This is a significant gap 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that is immediately clear, front-loaded with the action, and contains no unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
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 two string parameters, the description provides a minimally viable high-level understanding. However, it fails to explain what 'differences' means concretely (e.g., list of paths, unified diff, boolean), leaving the agent uncertain about the return value. Given the simplicity, a score of 3 is appropriate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already describes both parameters as 'First JSON string' and 'Second JSON string' (100% coverage). The description adds minimal extra meaning beyond 'JSON objects', so it meets the baseline but does not enhance understanding beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
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 'JSON objects', with an outcome of 'show differences'. It effectively distinguishes this tool from sibling diff_text (which is for text) and format_json (which is for formatting).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for comparing JSON content, but it does not explicitly state when to prefer this tool over alternatives or mention any exclusions. Sibling diff_text exists, but no guidance is provided to differentiate use cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. It only states that it queries JSON, but does not describe return value, error handling (e.g., invalid JSON, missing path), or whether it is read-only. Minimal behavioral context beyond the operation itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that front-loads the core concept and provides an illustrative example. Every word contributes value, with no unnecessary filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with full schema coverage, but there is no output schema and no behavioral details. The description does not explain what is returned or what happens on error, making it minimally viable but not complete for an agent that needs to anticipate edge cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, with both 'json' and 'path' well-defined in the schema. The description adds a concrete example of the path format, but no additional semantic value beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Query JSON with dot-notation path (e.g. 'users.0.name')' clearly states the verb (query) and resource (JSON), making the tool's purpose explicit. It also distinguishes itself from siblings like format_json and json_diff, which are formatting or diff tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The example path implies usage, but the description provides no explicit guidance on when to use this tool versus alternatives, nor does it mention any exclusions. Since no sibling tool directly competes, the implied usage is acceptable but not fully explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 lists the checks performed but omits return format, error handling, network side effects, or rate limits—critical behavioral information for an API that may perform MX lookups.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, front-loaded with the primary action and resource, and lists features succinctly without any redundant wording.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with one parameter, but there is no output schema or annotations. The description covers what validations are performed but not the structure of the result or error behavior, leaving the AI agent partially in the dark for invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema covers 100% of the parameter with a clear description ('Email address to validate'), so the baseline is 3. The description adds tool-level features but no additional parameter-specific semantics beyond what the schema already states.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific verb+resource ('Validate an email address') and enumerates distinct validation aspects (syntax, MX records, disposable detection, typo suggestions), clearly differentiating it from sibling tools like validate_ip or test_regex.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage is implied: the tool is meant for validating email addresses. The description does not provide explicit when-to-use or alternative guidance, but the sibling context makes its purpose clear. No exclusions 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, but it only restates the core transformation without disclosing edge-case handling, delimiter assumptions, error behavior, or whether the result is a raw string or parsed object.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Six words, zero fluff, direct statement of function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity, one fully documented parameter, and no output schema, the description plus schema provide adequate understanding, though a note on output shape (array of objects) would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single 'csv' parameter is fully described in the schema as 'CSV text with headers', and the description adds no additional semantic detail, so the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses the specific verb 'Convert' with clear subject 'CSV data' and result 'JSON array', distinctly differentiating it from sibling conversion tools like yaml_to_json and json_to_yaml.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the use case (converting CSV to JSON) but does not explicitly state when to choose this tool over alternatives or mention any exclusions or prerequisites beyond the schema's header requirement.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 states the core computation but does not specify the output format (e.g., ratio number, pass/fail), how invalid hex colors are handled, or any other operational details. This leaves significant ambiguity about 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that front-loads the action and resource. Every word serves a purpose, and there is no redundant or tangential content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a two-parameter tool with no output schema, the description covers the purpose but omits the return value and any edge-case behavior. Without an output schema, the agent must infer what the tool returns, which is a moderate gap. The simplicity of the tool partially compensates.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides 100% coverage with descriptions for both parameters ('Foreground color (hex)' and 'Background color (hex)'). The description only restates the roles of the parameters without adding deeper semantics such as format specifics, defaults, or constraints beyond what the schema already states.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'check' and identifies the resource as 'WCAG color contrast ratio' between foreground and background colors. It clearly distinguishes this from sibling tools like color_palette, which generates color palettes rather than checking contrast.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly conveys that the tool is for computing WCAG contrast between two colors, giving a clear usage context. It does not explicitly mention alternatives or exclusions, but the use case is obvious from the title and description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses the core behavior (parsing into description and computing next run times) but omits important behavioral details such as handling of invalid expressions, timezone assumptions, and output structure. Since this is a read-only parser, the lack of side-effect warnings is less critical, but timezone/error behavior would be valuable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that front-loads the primary action and clearly states the two outputs. Every word contributes value with no redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is moderately complex (cron parsing and scheduling), the schema covers parameters, but there is no output schema and the description does not specify the return structure or edge-case behaviors like timezone handling and error responses. This leaves gaps for an agent needing to interpret results or handle invalid inputs.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% for both parameters, so the baseline is 3. The description adds no parameter-specific semantics beyond what the schema already provides, such as example format for 'expression' and meaning for 'count'.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific verb ('Parse') and resource ('cron expression'), and specifies two concrete outputs: a human-readable description and next run times. This distinguishes it from siblings like parse_semver and datetime tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for interpreting cron expressions but does not explicitly state when to use this tool over alternatives or provide exclusions. No alternatives are mentioned, though no obvious sibling overlaps with cron functionality.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries the full burden. It states the tool returns meaning, category, and usage guidance, which is a basic disclosure of behavior. However, it does not describe the format of the response, any potential variations in output, or whether the tool performs any side effects. This is adequate for a read-only lookup but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that is front-loaded with the action and resource. Every word adds value, and there is no redundant or verbose language.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the low complexity (one parameter, no output schema, no annotations), the description is nearly complete: it tells the user what inputs are expected (via schema) and what outputs to expect (meaning, category, usage guidance). It does not elaborate on the structure of the output, but for a simple lookup, this is sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already documents the single parameter 'code' with a clear description and examples (e.g., 404, 502), achieving 100% schema coverage. The tool description adds no additional parameter-specific guidance, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Look up') and the resource ('HTTP status code'), with specific outputs ('meaning, category, usage guidance'). It is distinct from sibling tools, which cover regex, hashing, encoding, etc., so there is no ambiguity about what this tool does.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage: when you need information about an HTTP status code. However, it provides no explicit guidance on when to prefer this tool over alternatives, nor does it mention any exclusions or prerequisites. For a simple lookup utility, the implied context is acceptable but not explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 only states the conversion, without mentioning error handling for invalid JSON, output format details, or any potential edge cases. The agent is left to infer how the tool behaves beyond the basic transformation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that directly states the tool's purpose with no unnecessary words. It is minimal but effective for a simple conversion tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with only one parameter and no output schema. The description covers the core purpose, and the output (YAML) is implied. However, it lacks details on invalid input behavior and return value specifics, which are not compensated for by annotations or an output schema, so it is not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema provides 100% coverage with the parameter 'json' described as 'JSON string'. The description adds no additional semantic information beyond the schema, making the baseline of 3 appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Convert JSON to YAML' uses a specific verb and clearly states the resource transformation. It is distinct from siblings like yaml_to_json and format_json, 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.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly indicates the tool's function, implying it should be used when JSON needs to be converted to YAML. It does not explicitly state exclusions or alternatives, but the sibling tool 'yaml_to_json' supplies contextual contrast. This is clear context without explicit when-not guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It states the validation and identification functionality but does not disclose edge-case behaviors, error handling, or return format. However, for a read-only validation tool, the description is reasonably adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that directly states the core functionality. No unnecessary words or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
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 provides enough context for an agent to understand its purpose and likely return values. It does not elaborate on the meaning of 'type' and 'range', but these are self-explanatory in the IP context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single 'ip' parameter, which already describes it as the IP address to validate. The description adds no additional semantic detail beyond the schema, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool validates an IP address and provides additional details (version, type, range). It uses a specific verb and resource, and distinguishes itself from siblings like validate_email and calculate_cidr.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for IP validation but does not explicitly mention alternatives or when not to use it. The context is clear, but there is no direct guidance on choosing this over sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry behavioral transparency. It discloses the output content (header, payload, expiration) and implies a read-only decode operation, but it does not address signature verification, malformed token handling, or whether expired tokens still decode—important behavioral gaps for a security-related tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
A single, front-loaded sentence with no filler. It states verb, object, and outcome efficiently.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with one fully documented parameter, and the description covers the primary purpose and output categories. However, there is no output schema and the description omits edge-case behavior (invalid tokens, signature verification), leaving some ambiguity for an agent invoking the tool autonomously.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema fully documents the single `token` parameter with 100% description coverage, so the description adds no extra parameter semantics beyond naming the JWT token. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'Decode' and a specific resource 'JWT token', and states the outcome ('to see its header, payload, and expiration'). This clearly distinguishes it from sibling encode/hash tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context: use this tool when you need to inspect the header, payload, or expiration of a JWT. It does not explicitly name alternatives or exclusions, but the JWT-specific scope is sufficient guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations present, the description carries the full burden of behavioral disclosure. It merely lists operations without stating what the tool returns (e.g., parsed components, boolean, or comparison result), how errors are handled, or any side effects. The ambiguity of 'compare' (since only one version parameter exists) further 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that lists the core actions and a key detail (range syntax). Every word earns its place, with no filler or repetition of schema information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
This is a relatively simple tool with two parameters and no output schema, so the description doesn't need extensive detail. However, the lack of any indication of return values or behaviors for the 'parse' and 'compare' operations leaves the agent uncertain about what to expect after invocation, making it incomplete for a no-output-schema scenario.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already provides descriptions for both parameters, giving 100% coverage. The description adds valuable semantic context by specifying the range syntax (npm-style ^, ~, >=, etc.), which clarifies how the 'range' parameter is interpreted and goes beyond the schema's generic example.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states the tool performs three related semver operations: parsing, comparing, and checking range satisfaction. This clearly distinguishes it from sibling tools, which are unrelated text/data/format utilities, and leaves no ambiguity about the domain.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The mention of 'npm-style ^, ~, >=, etc.' provides clear context for when the tool is applicable (npm/semver range checking). It does not explicitly name alternatives or exclusion criteria, but no sibling tool overlaps with semver functionality, so this context is sufficient for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
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 the core behavior: it calculates and returns range, broadcast, and host count. It doesn't mention edge cases like invalid input or IPv6 support, but for a pure calculation tool this is adequate transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is front-loaded with the action and resource, followed by the expected outputs. Every word earns its place with no filler or repetition.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple: one parameter, no output schema. The description explains the purpose and the computed values, which is sufficient for an agent to invoke it correctly. It could mention error handling or IP version support, but these are minor gaps given the tool's straightforward nature.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already describes the 'cidr' parameter with an example. The description adds no additional parameter semantics beyond the schema. With 100% schema description coverage, the baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb and resource: 'Calculate network details from CIDR notation' and lists concrete outputs (range, broadcast, host count). This clearly distinguishes it from sibling tools like validate_ip or convert_case.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage context is implied: you use this tool when you have a CIDR and need network details. There are no sibling tools that overlap, so exclusion guidance is unnecessary, but the description doesn't explicitly state when to use it vs alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. It adds useful context about supported glob syntax (**, ?, character classes, brace expansion), but does not state the return type (e.g., boolean), case sensitivity, or error behavior. This is a basic but not exhaustive disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that front-loads the core purpose and adds a parenthetical with feature details. Every word earns its place; there is no redundancy or extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with two fully documented parameters and no output schema, the description is mostly complete. It explains the tool's core function and glob syntax support. However, it omits explicit statements about return values (e.g., true/false) and potential edge cases, which would be helpful but are not critical for understanding basic usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema already provides 100% coverage with descriptions for both parameters ('pattern' and 'path'), including an example. The tool description does not add significant parameter-specific meaning beyond reinforcing that the pattern supports glob features. Baseline of 3 is appropriate as the schema handles parameter semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function with a specific verb ('Test') and resource ('file path matches a glob pattern'). It also enumerates supported glob features, distinguishing it from regex-based tools like test_regex. The purpose is unambiguous and directly reflects the tool name.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear context: it is for testing glob patterns, which implicitly indicates when to use it. However, it does not explicitly mention alternatives (e.g., test_regex for regex) or exclusions. The context is specific enough for a simple utility.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
