Available Tools
51 toolsai_text_chunkerB
Split large text into smaller semantic chunks for LLM context optimization or vector databases (RAG).
| Name | Required | Description | Default |
|---|---|---|---|
| text | Yes | The input text to chunk. | |
| strategy | No | The chunking strategy: 'character', 'word', 'sentence', or 'paragraph'. Defaults to 'paragraph'. | paragraph |
| chunkSize | No | The maximum character size of each chunk. Defaults to 1000. | |
| chunkOverlap | No | The number of overlapping characters between consecutive chunks. Defaults to 200. |
TDQS
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 does not explain how 'semantic' chunking works, what strategies actually do (e.g., are they truly semantic or just boundary-based?), performance characteristics, or any side effects. This leaves significant ambiguity for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is directly informative and front-loaded with the core action. Every word serves a purpose, with no repetition or fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite high schema coverage, the description does not explain the output format (e.g., array of chunk strings with metadata) or critical behavioral details like how semantic boundaries are determined. For a tool with 4 parameters and no output schema, the description should provide more context for an agent to use it effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% description coverage for all 4 parameters (text, strategy, chunkSize, chunkOverlap), including defaults and enum values. The description adds no additional meaning beyond the schema, so it meets the baseline of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb ('Split') and resource ('large text') and specifies the purpose ('for LLM context optimization or vector databases (RAG)'). It is distinct from sibling tools, which are data conversion, formatting, and utility tools, not related to text chunking.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides some context (LLM, RAG) but lacks explicit guidance on when to use this tool versus alternatives or when not to use it. It does not mention the different chunking strategies (character, word, sentence, paragraph) or how to choose chunkSize/chunkOverlap. The usage is implied 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.
data_csv_to_jsonB
Convert a CSV file or CSV string data to a JSON array.
| Name | Required | Description | Default |
|---|---|---|---|
| columns | No | If true, treats the first line as column names and outputs an array of objects. Otherwise outputs an array of arrays. Defaults to true. | |
| csvData | No | Raw CSV string data to parse. | |
| filePath | No | Local filesystem path to the CSV file. | |
| delimiter | No | The field delimiter character. Defaults to ','. | , |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states basic input and output. It does not disclose error handling, performance characteristics, encoding assumptions, or limitations like file size. The columns behavior is only in the schema, not reinforced in the description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence that efficiently conveys the tool's purpose without unnecessary words. It is front-loaded with the action and result.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Without an output schema, the description provides minimal context about the return format ('JSON array') but does not specify structure (array of objects vs arrays) or error cases. Given the tool's simplicity, it is moderately complete but could benefit from mentioning the 'columns' behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with detailed descriptions for each parameter, so the description adds no extra semantic value. Baseline 3 is appropriate as the schema already clarifies the parameters' meanings.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the conversion direction (CSV to JSON) and the input sources (file or string). It distinguishes itself from sibling tools like data_json_to_csv and data_xml_to_json by specifying the unique format conversion.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives, nor any mention of prerequisites or exclusion criteria. The description lacks context for choosing between filePath and csvData inputs.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
data_deduplicateB
Remove duplicate entries from a JSON array of objects or strings.
| Name | Required | Description | Default |
|---|---|---|---|
| key | No | Optional object property key to deduplicate by (e.g. 'id' or 'email'). If omitted, checks full object identity. | |
| arrayData | Yes | JSON string representing the array to deduplicate. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states the basic function. It does not disclose which duplicate is kept (first/last), error behavior for invalid JSON, or whether the input array is modified. Critical behavioral details are missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very concise (one short sentence). However, conciseness comes at the expense of missing essential details. It does not waste words, but it does not fully earn its place either.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has no output schema, so the description should explain the return value. It does not. Additionally, edge cases (empty array, invalid input) are unaddressed. For a tool with only two parameters, the description is incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description does not add meaning beyond the schema; it merely restates that the tool works with objects or strings, which is implied by the parameter types. No additional clarity on parameter format or constraints.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('remove duplicate entries') and the resource ('JSON array of objects or strings'). It effectively distinguishes from sibling tools like data_json_to_csv or data_diff_arrays, as none of them perform deduplication.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool over alternatives. It does not mention any prerequisites, context, or scenarios where deduplication is appropriate. The description is purely functional with no usage cues.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
data_diff_arraysA
Compare two JSON arrays of objects and return the differences (added, deleted, modified, unchanged).
| Name | Required | Description | Default |
|---|---|---|---|
| key | No | Optional unique key to match objects between arrays (e.g. 'id' or 'email'). | |
| arrayA | Yes | JSON string representing the baseline array. | |
| arrayB | Yes | JSON string representing the updated array to compare against A. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description explains the output categories (added, deleted, modified, unchanged) but does not disclose behavior when 'key' is omitted, how objects are matched by default, or edge cases like empty arrays or duplicate keys. With no annotations, more detail would be beneficial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with 15 words, highly efficient. No filler, every word contributes to understanding the tool's core functionality.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 3 parameters and no output schema, the description covers the main function and output categories. Missing details on default key matching and return format, but still provides a solid understanding of what the tool produces.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and the schema already describes each parameter adequately. The tool description does not add new semantic detail beyond the schema, so baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool compares two JSON arrays of objects and returns specific difference categories (added, deleted, modified, unchanged). This distinguishes it from sibling tools like developer_diff_json (which diffs arbitrary JSON) and developer_diff_files.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool over alternatives. Lacks information about prerequisites, limitations, or when not to use it (e.g., for non-array JSON structures).
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
data_json_to_csvB
Convert a JSON array of objects to a CSV string.
| Name | Required | Description | Default |
|---|---|---|---|
| filePath | No | Local filesystem path to a JSON file containing the array. | |
| jsonData | No | Raw JSON string (must represent an array of objects) to convert. | |
| delimiter | No | The field delimiter character to use. Defaults to ','. | , |
TDQS
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 basic output type (CSV string) but fails to disclose important behaviors like handling of nested objects, missing fields, error conditions, or performance implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
One sentence, 11 words, front-loaded with the core action. No superfluous content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so description should explain the output format (e.g., header row, quoting, escaping). It does not, leaving uncertainty about the resulting CSV structure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 100% coverage with clear descriptions for all three parameters. The description adds no additional meaning beyond schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (Convert) and the resource (JSON array of objects to CSV string). It directly distinguishes from sibling tools like data_csv_to_json, data_json_to_xml, etc.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives or when not to use it. The description implies conversion but lacks explicit context for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
data_json_to_xmlB
Convert a JSON object to an XML text string.
| Name | Required | Description | Default |
|---|---|---|---|
| jsonData | Yes | The JSON string representation of the object to convert. | |
| rootName | No | Optional root element name. Defaults to 'root' if input is an array or string. | root |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full burden. It describes the basic conversion but omits behavioral details such as handling of arrays, null values, or errors. For a simple conversion, this is adequate but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, concise and to the point. It wastes no words, but could be slightly more informative without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and a simple conversion, the description is minimally complete. It doesn't mention return format or edge cases, but the tool's purpose is clear. Sibling context doesn't demand more.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, with both parameters described well in the schema. The description adds no extra meaning beyond the schema, earning the baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Convert') and the resource ('JSON object to XML text string'), which is specific and distinguishes it from sibling tools like data_json_to_csv or data_xml_to_json.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. With many sibling tools for data conversion, the description should indicate typical use cases or limitations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
data_json_to_yamlA
Convert a JSON object or string to a YAML text string.
| Name | Required | Description | Default |
|---|---|---|---|
| jsonData | Yes | The JSON string representation of the object to convert. |
TDQS
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 accurately describes the transformation but lacks details on side-effects (likely none), error handling, or input validation. The description is adequate but minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that immediately states the action and outcome. No unnecessary words or details.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple with one parameter and no output schema. The description covers the core conversion purpose. However, it does not mention output format details or any limitations, leaving minor gaps. Overall, it is nearly complete for a low-complexity tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema covers 100% of parameters with a description of 'jsonData'. The description adds 'object or string', which may be ambiguous since the schema expects a string. This adds marginal value but also potential confusion. With full schema coverage, baseline score applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb 'Convert' and clearly states the resource: 'a JSON object or string to a YAML text string.' It distinguishes from sibling tools like data_json_to_csv and data_yaml_to_json.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
While the purpose is clear, there is no explicit guidance on when to use this tool versus alternatives. The description does not mention when not to use it or provide criteria for selection among 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.
data_xml_to_jsonA
Convert an XML string to a structured JSON object.
| Name | Required | Description | Default |
|---|---|---|---|
| xml | Yes | The XML text string to convert. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, and the description only says 'convert' without detailing behavioral traits such as handling of namespaces, attributes, or potential errors. This is insufficient for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no wasted words. It is maximally concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter tool, the description covers the basic purpose but lacks details on output format specifics or error scenarios, making it adequate but not complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with a clear parameter description. The tool description adds no extra meaning beyond what the schema provides, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action (convert) and resource (XML string to structured JSON object), which distinguishes it from sibling tools like data_json_to_xml.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage (when you need XML to JSON conversion) but does not explicitly provide when-to-use or alternative guidance among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
data_yaml_to_jsonB
Convert a YAML string to a structured JSON object.
| Name | Required | Description | Default |
|---|---|---|---|
| yaml | Yes | The YAML text to convert. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility for behavioral disclosure. It only states conversion without mentioning error handling (e.g., invalid YAML input), limitations, or side effects. This is insufficient for a simple conversion tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence of 10 words, which is concise and front-loaded. However, it lacks any structured breakdown or additional context, so not a perfect 5.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple one-parameter conversion tool without an output schema, the description adequately states purpose and parameter. However, it would benefit from mentioning behavior on invalid YAML or the output format, making it minimally complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and the single parameter 'yaml' is described as 'The YAML text to convert.' The tool description adds no new meaning beyond what the schema provides, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool converts a YAML string to a structured JSON object. It uses a specific verb ('Convert') and resource ('YAML string to structured JSON object'), and among sibling data conversion tools, it uniquely addresses YAML-to-JSON conversion.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like data_csv_to_json or data_json_to_yaml. The description does not provide any context for selection among the many data conversion tools listed.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
developer_code_detectorB
Detect the programming language of a raw code snippet using heuristic analyzers.
| Name | Required | Description | Default |
|---|---|---|---|
| code | Yes | The raw programming code snippet to analyze. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavioral traits. While it mentions 'heuristic analyzers,' it lacks details on accuracy, supported languages, or edge cases like ambiguous snippets. This minimal disclosure is insufficient for an agent to anticipate behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence with no extraneous information. While concise, it could be more informative about the tool's behavior and limitations.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of an output schema, the description should explain what the tool returns (e.g., language name, confidence score). It does not, nor does it mention supported languages or error handling, making it incomplete for an agent to fully understand the tool's capabilities.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema fully describes the single 'code' parameter (100% coverage), so the description adds no extra semantic value beyond what the schema already provides. 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.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: detecting the programming language of a raw code snippet. It uses a specific verb ('Detect') and resource, and it uniquely distinguishes itself from sibling tools, none of which perform language detection.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, nor does it mention any limitations or prerequisites. It simply states what it does, leaving the agent without context for appropriate use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
developer_cron_parserA
Parse a cron expression to validate it, explain its scheduling, and list its next execution dates.
| Name | Required | Description | Default |
|---|---|---|---|
| expression | Yes | The 5-field or 6-field cron expression to parse (e.g. '*/5 * * * *'). | |
| iterations | No | Number of upcoming execution times to calculate. Defaults to 5. |
TDQS
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 key behaviors (validate, explain, list dates) but does not detail error handling on invalid expressions, output format, or any side effects. Adequate but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with 17 words, front-loaded with the main action. Every part is necessary; no wasted text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description should explain return values more thoroughly. It mentions listing dates and explaining scheduling but omits format and validation failure behavior. Completeness is adequate for a simple utility tool but has gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, with both parameters having clear descriptions. The overall description does not add extra semantics beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool parses a cron expression and performs three specific actions: validate, explain scheduling, and list next execution dates. There are no sibling tools with similar purpose, so no differentiation needed.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for parsing cron expressions but provides no explicit guidance on when to use it versus alternatives, nor any exclusion criteria. Given no sibling cron tools, lack of guidance is less critical but still a gap.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
developer_diff_filesA

| contentB | Yes | The modified text content to compare. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It only states the basic function without disclosing any behavioral traits such as size limits, performance characteristics, or side effects. This is insufficient for a tool with no annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence front-loads the action and output type. No wasted words; efficient and clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that the tool has no output schema, the description could explain the output format more thoroughly, but 'Git-style line-by-line diff' provides enough context for an agent to understand what to expect. Missing details on return value structure (e.g., array of lines, string) reduce completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with all parameters described. The description adds no further meaning beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'compare' and resource 'two text contents', and specifies output as 'Git-style line-by-line diff'. This distinguishes it from sibling tools like developer_diff_json which compare JSON objects.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description does not explicitly state when to use this tool versus alternatives like developer_diff_json. However, the name and description imply it is for plain text files, and the sibling for JSON diffs is different enough that an agent could infer usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
developer_diff_jsonB
Perform a structural, nested properties diff comparison between two JSON objects.
| Name | Required | Description | Default |

| jsonA | Yes | JSON string of the baseline object. | |
| jsonB | Yes | JSON string of the updated object. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavior. It mentions 'structural, nested properties' but does not clarify output format, case sensitivity, handling of identical objects, depth limits, or performance characteristics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-formed sentence with no unnecessary words. It could be slightly more informative but earns high marks for efficiency.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is insufficient for complete understanding. It omits output format (e.g., list of changes), behavior for identical objects, error handling, and any limitations. No annotations or output schema exist to fill gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% (both jsonA and jsonB have descriptions), so the baseline is 3. The description adds minimal value beyond the schema, only reiterating the 'structural, nested' nature without enriching parameter meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'perform' and the resource 'diff comparison between two JSON objects', and adds specificity with 'structural, nested properties', which effectively distinguishes it from siblings like data_diff_arrays (array diffs) and developer_diff_files (file diffs).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives (e.g., data_diff_arrays for arrays, developer_diff_files for files). No context about prerequisites or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

| minify | No | If true, outputs minified JSON. If false, pretty-prints it. Defaults to false. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden. It states validation and formatting/minification, which is adequate but doesn't disclose error handling (e.g., behavior on invalid JSON) or output structure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence of 8 words, with no unnecessary words. Every part is essential.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Without an output schema, the description adequately covers the tool's core functionality. It could be slightly more explicit that the output is a formatted/minified JSON string, but the current text is sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description adds value by grouping operations (validate, format, minify) and indicating the tool's purpose, going beyond what individual parameter descriptions provide.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool validates, formats (pretty-prints), or minifies JSON strings. This sets it apart from sibling tools that convert between formats (e.g., data_json_to_csv) or perform other operations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden for behavioral disclosure, but it only states the conversion operation. It does not mention side effects (e.g., file overwriting), error handling, output behavior when outputPath is omitted, or 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence with no unnecessary words. It is front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is too brief given the tool has 4 parameters, no output schema, and important behavioral details (e.g., what happens if outputPath is not provided) are missing. While the tool is simple, the description should still cover key behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3. The description does not add new meaning beyond the schema; it repeats the supported formats already defined in the enum.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool converts an image to a different format and lists supported formats (png, jpeg, bmp). It effectively distinguishes from sibling tools like image_resize or image_compress, though it does not 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.
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. There are no explicit exclusions, prerequisites, or comparison to siblings such as image_compress or image_resize.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

| Name | Required | Description | Default |
|---|---|---|---|
| fileData | No | Base64 encoded image data. | |
| filePath | No | Local path to the image file. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so description bears full burden. It only states the action without disclosing behavior on non-JPEG files, missing EXIF, invalid paths, or read-only nature. Minimal behavioral insight 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, front-loaded with key info, no redundant words. Every word earns its place. Exceptionally concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple tool (2 params, no output schema), the description adequately covers purpose and scope. Could mention return format or error cases, but not essential for this extraction task.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with basic descriptions. The description adds value by listing example metadata (camera, GPS, capture date), helping agents understand what the tool returns beyond schema-provided parameter definitions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses specific verb 'Extract' and resource 'EXIF metadata tags from JPEG images' with examples (camera, GPS, capture date). It clearly distinguishes this tool from siblings that handle image compression, conversion, OCR, resizing, and other operations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use (extracting EXIF data from JPEG images) but no explicit guidance on when not to use, file format restrictions, or alternatives. Context is clear but lacks exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It mentions Tesseract OCR but does not disclose limits (size, accuracy, timeout), failure modes, or that it returns plain text only. The description is insufficient for an agent to anticipate tool behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the core action and resource. It is concise, but the second sentence could be integrated more smoothly. Still, every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 3 parameters, no output schema, and no annotations, the description should clarify return format, error handling, and prerequisites like Tesseract installation. It lacks these details, leaving the agent underinformed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds context beyond the schema by mentioning Tesseract and confirming both local file path and base64 data are supported, which enhances parameter understanding.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool extracts text from images using Tesseract OCR, specifying supported formats (PNG, JPEG) and input methods (file path or base64). It effectively distinguishes from sibling tools, none of which perform OCR.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for text extraction from images and mentions input options, but lacks explicit guidance on when to use this tool over alternatives or exclusions. No sibling tool performs similar function, so context is clear but not explicitly stated.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
image_resizeB

| outputPath | No | Optional local path where the resized image should be saved. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries full burden. It does not disclose side effects, such as whether the original file is modified, or how it handles the oneOf requirement for filePath vs fileData. The optional height and output path are not explained beyond what's in the schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single sentence that is concise and to the point. It could be slightly improved by noting the optional height or the oneOf input methods, but it is not verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 5 parameters and no output schema, the description is too minimal. It doesn't explain the oneOf constraint, the optional height scaling, or expected return value. It lacks completeness for an agent to fully understand tool behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description adds no additional meaning beyond what the schema already provides for each parameter. It merely restates the purpose without clarifying constraints like oneOf or optional scaling.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool resizes images to specific width and height, using specific verb+resource. This distinguishes it from siblings like image_compress or image_convert_format, which have different purposes.

No annotations provided, so description carries full burden. It states it returns 'feed items in a structured JSON array' but lacks details on error handling, rate limits, redirect behavior, or authentication requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence that is front-loaded and contains zero unnecessary words; every piece of information earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a low-complexity tool (1 param, no output schema, no nested objects), the description is fairly complete, covering input, action, and output format, though it omits error scenarios.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% with one parameter, and description adds no extra meaning beyond what the schema already provides ('The URL of the RSS/Atom feed'). Baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description uses specific verb 'Parse' and resource 'RSS or Atom feed XML URL', clearly distinguishing it from sibling 'utility_url_parser' which deals with general URL parsing.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Description implies usage for parsing RSS/Atom feeds but does not provide explicit when-to-use or when-not-to-use guidance compared to siblings like 'web_extract_links' or 'web_extract_metadata'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
web_sitemap_generatorA
Fetch and parse a sitemap.xml URL, extracting all listed URLs.
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | The sitemap XML URL, or the homepage URL (the tool will auto-check standard sitemap paths if a page is passed). |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses an important behavioral aspect: it can accept a homepage URL and auto-check standard sitemap paths. However, since no annotations are provided, it does not explicitly state that the operation is read-only or safe, though 'fetch and parse' implies no side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that conveys the core functionality without unnecessary words. It is front-loaded and efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the main functionality and parameter flexibility. However, since no output schema exists, it only hints at the output ('extracting all listed URLs') without specifying the format (e.g., array of strings). This is a minor gap for a low-complexity tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and the schema itself provides detailed parameter semantics (e.g., accepting homepage URLs). The description adds no additional parameter information beyond what the schema already conveys, resulting in a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Fetch and parse' and the resource 'sitemap.xml URL', with the outcome 'extracting all listed URLs'. This distinguishes it from sibling tools like web_extract_links or web_rss_parser, which have different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives, nor are there any exclusions or prerequisites mentioned. The description only states what the tool does without contextual usage advice.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
web_to_markdownA
Fetch a web page, clean up clutter (scripts, styles, footer, navigation), and convert the main body to Markdown.
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | The URL of the webpage to scrape and convert. |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses that scripts, styles, footer, navigation are removed, but no annotations exist. Lacks details on rate limits, authentication, error handling, or JavaScript execution. Adequate but not exhaustive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
One sentence, front-loaded, no wasted words. Every part is essential and clearly communicates the tool's function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Simple tool with one parameter and no output schema. Description covers main behavior and output format. Could mention limitations like dynamic content handling, but remains fairly complete for its simplicity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Single parameter 'url' with schema description 'The URL of the webpage to scrape and convert.' Schema coverage is 100%, so baseline 3. Description adds no extra semantics beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states verb (fetch, clean, convert), resource (web page), and output (Markdown). Differentiates from sibling tools like web_extract_links and web_extract_metadata by specifying conversion and clutter removal.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Implied usage for converting web content to Markdown, but no explicit when-to-use or alternatives. With 40+ sibling tools, guidance on when to prefer this over others (e.g., web_extract_metadata) is missing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
web_youtube_transcriptA
Extract text transcripts and captions with timestamps from a YouTube video URL.
| Name | Required | Description | Default |
|---|---|---|---|
| url | Yes | The URL of the YouTube video. | |
| languageCode | No | The preferred language code for transcripts (e.g. 'en', 'es'). Defaults to 'en'. | en |
TDQS
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 mentions transcripts with timestamps but omits critical details: what happens if no transcript exists, how it handles autogenerated vs manual captions, rate limits, or authentication. The description is too sparse for a transparent understanding.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, concise sentence that front-loads the action and resource. Every word contributes meaning, with no redundancy or filler. It is optimally brief for the information conveyed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple (2 parameters, no output schema), so the description is adequate for basic understanding. However, it lacks information about return format beyond timestamps, error handling, or supported languages. For a transcript extraction tool, more context (e.g., fallback behavior) would be appropriate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% parameter description coverage, documenting both 'url' and 'languageCode'. The description adds only 'with timestamps' as output context, which does not enhance parameter understanding. With full schema coverage, the baseline is 3; the description does not improve parameter semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Extract' and the resource 'text transcripts and captions with timestamps from a YouTube video URL'. It uniquely identifies the tool's function, and among sibling tools (e.g., data utilities, web extractors), none overlap in purpose, ensuring distinction.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool is for extracting YouTube transcripts but lacks explicit guidance on when to use it versus alternatives, prerequisites (e.g., URL validity, caption availability), or exclusion criteria. No sibling tool directly competes, so the lack of alternatives is mitigated, but usage context is minimal.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Each tool targets a distinct operation, with clear category prefixes and unique action-noun combinations. No two tools appear to do the same thing.
Tools follow a consistent category_operation pattern, but the operation style varies (e.g., verb_noun, noun_to_noun, noun_noun). This minor inconsistency does not hinder understanding.
With 51 tools, the set is large but justified by the broad utility scope of a 'kitbag'. However, the count is on the high side, potentially overwhelming for an agent.
The toolkit covers a wide range of common tasks: data conversion, image processing, PDF handling, web scraping, developer utilities, and more. No obvious gaps for a general-purpose utility server.
