Server Quality Checklist

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

Latest release: v0.1.0
Disambiguation4/5
Most tools have clearly distinct purposes (e.g., get_contributors vs get_language_breakdown). Some overlap exists between get_repo_info, get_repo_stats, and generate_repo_summary, but descriptions clarify their roles. get_diff and get_pr_diff are similar but context-specific.
Naming Consistency4/5
Tools consistently use snake_case verb_noun patterns like list_, get_, search_, clone_, checkout_. Minor deviations like pull_latest are still readable and do not break the overall pattern.
Tool Count3/5
25 tools is at the upper edge of the borderline range. While many are focused, there is redundancy (e.g., get_repo_info and get_repo_stats could be consolidated), making the set feel heavier than necessary.
Completeness3/5
The server provides extensive read-only repo metadata and local git operations, but lacks write operations like creating/updating issues or PRs, and lacks push/commit capabilities. This leaves notable gaps for a server named 'ops'.
Average 2.9/5 across 25 of 25 tools scored. Lowest: 1.8/5.

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

Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations available, the description bears full responsibility for disclosing behavior such as read-only nature, return format, auth requirements, or side effects. 'Repo topics/tags.' offers none of this, leaving the agent completely uninformed about the tool's runtime characteristics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The phrase 'Repo topics/tags.' is extremely under-specified rather than concise. It omits essential information that would make its brevity useful, similar to the 'Process' example where minimal text does not serve the reader.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with a single parameter and no output schema, a complete description would be a single sentence stating it returns the topics/tags for a given repository. The current fragment leaves purpose, parameter expectations, and behavior entirely unstated, rendering the description insufficient even for a simple tool.
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?
The parameter owner_repo has no schema description (0% coverage), and the description does not compensate by explaining the expected format (e.g., 'owner/repo') or its role. The tool description fails to add any meaning to the bare property name.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Repo topics/tags.' is a noun phrase that identifies the resource but lacks an explicit verb such as 'get' or 'list'. It vaguely conveys the tool's subject matter but leaves the action ambiguous, though the name 'get_topics' provides some clue.
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 any alternatives, no contextual hints, and no exclusions. The description provides zero direction for selection among a large set of 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 provided, the description carries the full burden of disclosing behavior. It only states the output unit (percentages of bytes) but does not disclose whether the operation is read-only, requires authentication, has rate limits, or any other behavioral aspects. This is a minimal disclosure for a getter tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single short noun phrase, which is concise in word count but significantly under-specified. It does not form a complete sentence and omits critical operational context, making it more of an incomplete fragment than a valuable concise description.
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 tool has one required parameter and no output schema, the description is not complete. It fails to explain the input parameter, the full return shape (e.g., what languages are included, if any limits exist), or any edge cases. The description only gives a hint about the output metric, which is insufficient for selecting and invoking the tool correctly.
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 explain the 'owner_repo' parameter at all. The description adds no meaning beyond the parameter name, leaving the agent to infer that it likely is a repository identifier, but with no formatting or usage details.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Language usage as percentages of bytes' is a noun phrase that vaguely indicates the tool returns language usage broken down by byte percentages. It is not a clear verb+resource statement and lacks explicit differentiation from sibling tools like get_repo_stats or get_topics, though the focus on language usage provides some specificity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
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, no prerequisites, and no exclusion criteria. It does not mention that it should be used for analyzing language distribution in a repository or any similar usage context.
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 carry the full burden of behavioral disclosure. It only states the output value and does not clarify whether the operation is read-only, rate-limited, error-prone, or what input format is expected, which is a significant gap for safe invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely brief (five words), but this brevity is under-specification rather than conciseness. It reads as a truncated label rather than a well-formed sentence, offering minimal useful information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Without an output schema or annotations, the description is the sole source of context. It fails to describe the return format, potential errors, or the input parameter, making it incomplete for even a simple 1-parameter tool.
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?
The input schema has one required parameter, owner_repo, with 0% description coverage. The description does not elaborate on the expected format (e.g., 'owner/repo' syntax) and adds no value beyond the parameter name itself.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'License name for the repo.' is a noun phrase rather than a verb phrase, but it does identify the tool's output (license name) and distinguishes it from sibling tools focused on other repo attributes. It lacks a strong verb like 'retrieves' or 'gets', which would more clearly state the action.
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 siblings like get_repo_info or get_topics. The description does not mention any use case, prerequisites, or alternative tools, leaving the agent without decision support.
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 does not mention whether the operation is read-only, what kind of diff is returned (unified, name-only, etc.), or any side effects. The description adds minimal behavioral context beyond stating the obvious.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single short sentence, which is concise in length, but it under-specifies the tool's purpose and behavior. It is not front-loaded with the most important action; it reads more like a label than a useful explanation.
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 three required parameters, no output schema, and no annotations, the description is inadequate for an agent to understand what the tool returns or how to invoke it correctly. It lacks information about the diff format, whether both branches and commits are acceptable, and how repo_path is used.
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?
Schema description coverage is 0%, so the description must explain parameters. It does not describe 'base', 'head', or 'repo_path' roles, leaving the agent to infer meaning from parameter names alone. No compensation for the missing schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Diff between two branches or commits' indicates the tool computes a diff, but lacks an explicit verb like 'show' or 'get'. It names the resource (branches/commits) but does not distinguish it from sibling 'compare_branches' or 'get_pr_diff'.
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. Sibling tools like compare_branches or get_pr_diff likely overlap, but the description gives no context for 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 present, so the description carries the full burden. It only declares the output scope but does not disclose the response format, the meaning of 'recent', pagination, or any API behavior. This is insufficient for a tool with no other behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single short sentence, which is easy to read and front-loaded. However, the brevity sacrifices necessary detail, making it minimally viable but not exceptional.
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 annotations, no output schema, and a description covering only basic output, the tool is under-specified. The agent lacks information about parameter formats, response structure, or usage constraints, which is a significant gap for a tool with two parameters.
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 tool description does not explain the 'owner_repo' or 'limit' parameters. The schema only provides a default for 'limit', but no semantic meaning is given. The description adds no parameter insight, so the agent must guess.
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 returns the latest release plus recent release/tag history, making the primary function apparent. It lacks an explicit verb but the meaning is unambiguous. There are no sibling release-specific tools, so differentiation is not needed, though it could be more precise.
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 or when to prefer an alternative. It simply states the output without any context on scenarios or boundaries, leaving the agent without direction on 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?
With no annotations, the description must carry the full burden of behavioral disclosure. It only says 'Fetch', implying a read operation, but does not disclose return format, potential errors, authentication needs, or what 'quick metadata' specifically includes. This leaves significant gaps.
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, front-loaded sentence with no unnecessary wording. However, it is somewhat under-specified, though not to the extreme of a tautology. It earns a high score for conciseness but loses a point for lacking substance that could justify its brevity.
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 simple 1-parameter tool, the description gives only a vague idea. There is no output schema and no annotations, so the description needs to convey what metadata is returned and how the parameter is formatted. It fails to provide this, leaving the tool incomplete for the agent.
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?
The input schema has zero description coverage for the only parameter (owner_repo), and the description does not compensate by explaining the expected format (e.g., 'owner/repo'). The parameter name gives some hint, but the meaning is not explicitly clarified, failing the low-coverage compensation requirement.
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 ('Fetch') and resource ('metadata for a repo'), indicating what the tool does. However, 'metadata' is vague and does not distinguish it from sibling tools like get_repo_stats or get_topics, so it misses the differentiation criterion.
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 the many alternatives (e.g., get_repo_stats, get_contributors). There is no mention of scenarios, prerequisites, or exclusion criteria.
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 bears full responsibility for behavioral transparency. It only states the basic action and the inclusion of CI status, without disclosing pagination behavior, output structure, whether the operation is read-only, or any authentication requirements. The 'CI check status' phrase implies additional data but does not explain its representation.
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, front-loaded sentence with no redundant words. It is appropriately concise for a simple tool, though it could be more informative without becoming verbose.
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?
There is no output schema, and the description provides only a high-level action. It does not explain what the returned data contains (e.g., PR numbers, titles, CI status details), whether results are paginated, or how it handles edge cases like no open PRs. This leaves significant gaps for an agent making a selection decision.
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 explain the owner_repo parameter. While the parameter name hints at owner/repo, the format and expected value are undocumented. The description adds no meaning beyond the schema's field name and type.
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 lists open PRs and includes CI check status, using a specific verb and resource. It distinguishes from sibling tools like list_open_issues and get_pr_diff, though it doesn't explicitly name them. The mention of 'CI check status' is slightly ambiguous but doesn't 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?
The description provides no guidance on when to use this tool versus alternatives such as list_open_issues or get_pr_diff. It does not mention any prerequisites, filtering conditions, or cases where another 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 burden of behavioral disclosure. It only mentions the output content (forks with owner and star counts) and does not indicate whether the operation is read-only, whether authentication is required, how limit affects results, or any potential errors or pagination 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, succinct sentence that front-loads the verb and key output fields. Every word earns its place, with no unnecessary elaboration.
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 lack of annotations, output schema, and parameter descriptions, this minimal description is insufficient for an agent to reliably select and invoke the tool. It does not explain input formatting, limit semantics, or the overall output structure beyond listing forks.
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 explain the 'owner_repo' or 'limit' parameters. The agent cannot infer the required format of owner_repo (e.g., 'owner/repo') or how limit controls the number of forks returned. The description adds no semantic value beyond the schema's bare parameter names.
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 that the tool lists forks with owner and star counts, using a specific verb and resource. It distinguishes from siblings like get_contributors or get_repo_info, though it does not explicitly mention 'for a given repository'—this is implied by the required owner_repo parameter.
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 or contrasting with sibling tools such as get_repo_stats or list_pull_requests. The description simply states the function 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden of behavioral disclosure. However, it simply restates the tool name and mentions a label filter, without disclosing read-only behavior, pagination, default limits, authentication requirements, or sorting. It adds no meaningful behavioral context beyond what the name implies.
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 highly concise, using six words to convey the core action and an optional modifier. It is front-loaded with the primary purpose and contains no filler or redundancy. Every word earns its place, making it appropriately sized for a simple list operation.
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 and no annotations, the description is under-specified. It does not mention the required repository parameter, the structure of returned data, pagination behavior, or any limits. For a tool with a required parameter and zero schema/annotation support, this is a significant completeness gap.
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?
Schema description coverage is 0%, and the description only explains the optional label parameter ('optionally filtered by label'). The required owner_repo parameter is not explained at all, including its expected format (e.g., 'owner/repo'). The label mention adds some value, but the description fails to compensate for the complete lack of schema-level descriptions.
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 ('List open issues') and an optional filter (by label), which identifies the resource and operation. It does not explicitly mention 'for a repository,' but the required owner_repo parameter and sibling tool names (e.g., list_pull_requests) make the repository context implicit. It is distinguishable from sibling tools by focusing on issues.
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 like search_repos, list_pull_requests, or get_repo_info. There are no stated prerequisites, exclusions, or scenarios where this tool is preferable. The only hint is the 'open issues' scope, but no explicit when-to-use guidance is given.
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 exist, so the description must disclose behavioral traits. It only hints at mutation with 'optionally creating it' but does not explain side effects, such as whether uncommitted changes are blocked, what happens if the branch already exists, or whether the repository is modified locally.
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, front-loaded, with no filler. It is concise and to the point, though it sacrifices detail that would be necessary for complete understanding.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of annotations, an output schema, and detailed parameter descriptions, this tool with 3 parameters is drastically under-specified. The description provides almost no context about behavior, return values, or constraints, making it inadequate for an agent to invoke correctly.
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?
Schema description coverage is 0%, and the description does not clarify the parameters beyond the obvious. 'Optionally creating it' vaguely maps to `create_new`, but `repo_path` and `branch` are left undefined in terms of format or constraints.
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 ('Switch to a branch') and the resource (branch), with an additional capability ('optionally creating it'). It is specific and distinguishes itself from sibling tools that focus on listing or comparing branches.
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, nor are prerequisites mentioned (e.g., clean working tree, branch existence). The description implies usage by stating the action but lacks any context on appropriate conditions or alternatives.
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 disclosing behavioral traits. It states the output is weekly counts over a year but does not clarify aspects like whether weeks with zero commits are included, response format, pagination, or authentication requirements. This is a significant gap for a tool with no other behavioral metadata.
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 conveys the core functionality without any unnecessary words. It is front-loaded with the key information (weekly counts and time range) and achieves high efficiency.
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 one parameter and no output schema, the description gives a basic understanding of what is returned, but it lacks details about the exact structure of the response and edge cases. The absence of annotations and output schema means the agent must infer behavior from the minimal text, leaving some ambiguity.
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 input schema has one parameter, owner_repo, with 0% description coverage. The description does not mention or explain this parameter, relying entirely on the self-explanatory name. It fails to add any additional meaning about the parameter's format or relationship to the returned data.
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 returns weekly commit counts over the last year, providing a specific resource and time range. It implicitly distinguishes from sibling tools like list_commits by indicating aggregated counts rather than individual commits. However, it lacks an explicit verb, relying on the tool name for action.
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 such as list_commits or get_repo_stats. The description does not mention any exclusions or prerequisites, leaving the agent to infer appropriate usage from the name and context.
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 that a raw diff is returned, without detailing error handling, authentication requirements, or the exact format of the diff. Minimal behavioral context is given.
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 or redundant information. Every word contributes to the core meaning.
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?
As a simple read tool with no output schema and no annotations, the description is too minimal. It does not specify the return value's structure beyond 'raw diff', nor does it mention likely error conditions, making it incomplete for an agent to invoke confidently.
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?
The schema has 0% description coverage for its two parameters, and the tool description does not clarify their format or usage. 'owner_repo' could be interpreted as a combined string or separate values, and no compensation is made for the missing parameter documentation.
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 ('Return') and the specific resource ('the raw diff for a given PR'), making it unambiguous. The mention of 'PR' distinguishes it from sibling tools like get_diff or compare_branches.
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 get_diff or compare_branches. It simply states what it does without any 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?
With no annotations, the description must disclose behaviors (e.g., read-only, API rate limits, authentication requirements, or return format details). It only lists output fields without any behavioral context, leaving the agent unaware of potential side effects or constraints. This is a significant gap, especially for an API-bound 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 fragment with no wasted words. It efficiently conveys the core output without verbose phrasing, making it easy to parse quickly.
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 (one param, no output schema, no annotations), and the description lists the returned stats, which is adequate for a basic understanding. However, it omits how the parameter relates to the output, lacks usage context, and does not clarify edge cases (e.g., 'timestamps' for what events). It is minimally viable but with clear gaps.
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 has a single parameter 'owner_repo' with 0% description coverage, so the description must compensate. It does not mention the parameter at all, nor does it explain the expected format (e.g., 'owner/repo'). However, the single parameter name is self-explanatory, mitigating some ambiguity.
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 enumerates the specific data returned (stars, forks, watchers, open issue/PR counts, size, timestamps), making the tool's purpose clear and distinguishing it from sibling tools like get_repo_info or get_contributors. It lacks an explicit verb like 'retrieves', but the list of metrics strongly implies the action and resource.
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 'use this for quantitative metrics' or 'use get_repo_info for qualitative details.' No exclusions or preferred contexts are mentioned, so the agent must infer usage from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the core behavior (computing ahead/behind counts) and implies a read-only operation. However, with no annotations, it does not clarify whether the counts are commit-based, whether remote fetching occurs, or any side effects beyond the schema's repo_path.
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 short sentence with no filler, fully front-loaded, and to the point. Every word earns its place, making it highly 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?
No output schema exists and annotations are absent, so the description must explain the return shape and operational context. It only says 'counts' without specifying whether these are commit counts, and it omits prerequisites like local repository state or whether branches must exist.
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?
Schema description coverage is 0%, and the description only mentions 'between two branches,' which maps to branch_a and branch_b but adds no detail about ordering or repo_path. The parameter names are self-explanatory, but the description fails to clarify whether ahead/behind is relative to branch_a or branch_b.
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 that the tool computes ahead/behind counts between two branches, which is a specific and distinguishable operation. It distinguishes itself from sibling 'get_diff' by focusing on counts rather than diff content, though it lacks an explicit verb like 'returns'.
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 get_diff or list_commits. The description does not mention any exclusions, prerequisites, or scenarios for use, leaving the agent without 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?
No annotations are present, so the description must carry the full burden of disclosing behavior. It states only the output categories, omitting details about error handling, ignored files, or the exact format of the status output, which limits transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, compact sentence that directly presents the core functionality without any redundant phrasing. It is well-structured and front-loaded, showing respect for the reader's attention.
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 one parameter and no output schema, the description gives a basic sense of what to expect (status split into categories), but it lacks context about the required repo_path parameter, potential errors, or what the actual output looks like. It is minimally viable but not fully complete.
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?
The schema lists a single required parameter, repo_path, but the description does not mention it. With 0% schema description coverage, the description fails to compensate by explaining what the parameter means or how it should be used, providing no value beyond the schema field name.
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 identifies the tool as reporting working-tree status, explicitly split into staged, unstaged, and untracked files. This distinguishes it from sibling tools focused on branches, commits, or diffs, making the purpose 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?
The description offers no guidance on when to use this tool versus alternatives like get_diff or list_commits. There is no mention of prerequisites, typical scenarios, or exclusions, leaving the agent to infer usage from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
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 output ordering but omits whether the operation is read-only, how pagination works, if the sort is descending, or any rate-limit considerations. This is minimal 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, front-loaded sentence with no fluff. It efficiently communicates the core function and ordering without wasting words, making it easy to parse 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?
Given the low complexity (2 params, no output schema), a minimal description could suffice, but this one omits critical context: the repository identifier format, the return value shape, and any assumption about the default limit. It leaves the agent with too many unknowns for confident 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?
Schema description coverage is 0%. The description's phrase 'top contributors' implicitly suggests the limit parameter sets the number of contributors, but it does not explain owner_repo format (e.g., 'owner/repo') or clarify limit's behavior beyond the schema default. The description fails to compensate for the missing parameter documentation.
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 returns top contributors ranked by commit count. This specific verb-resource combination distinguishes it from sibling tools like list_commits (which lists commit records) and get_repo_stats (which provides broader repository statistics).
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 such as get_commit_activity or list_commits. There is no mention of preferred use cases or exclusions, leaving the agent without decision support.
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 full responsibility for disclosing behavior. It only says 'show,' which implies a read operation, but it does not clarify return format, pagination, rate limits, or whether the operation requires authentication. This is insufficient for a tool with no structured safety metadata.
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, succinct sentence with no redundant or filler words. It is appropriately sized for the minimal function it describes, though it sacrifices informative content for brevity.
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 tool has two parameters, no output schema, and no annotations, the description is too minimal to be complete. It omits return value details, parameter semantics, and any operational context that would help an agent determine if this tool is suitable.
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 input schema has 0% description coverage, and the description only marginally hints at the 'n' parameter via 'last N commits.' It does not explain 'repo_path' or add any semantic detail beyond the parameter names. The description fails to compensate for the lack of schema documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Show the last N commits' clearly identifies the action (show) and the resource (commits) with a specific scope (last N). It is easily distinguishable from sibling tools like list_pull_requests or get_commit_activity, which focus on different aspects of repository history.
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, no exclusions, and no mention of prerequisites. It is a bare statement without context on typical use cases or conditions.
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 burden of behavioral disclosure. It adds value by noting the 'no-op if already cloned' idempotency and the sandboxed workspace destination. However, it doesn't disclose other aspects like network requirements, authentication, or error behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence with no filler. Every word contributes to the core purpose and key nuance (no-op behavior). Efficient and appropriately sized.
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 clone tool with no output schema and no annotations, the description is minimal but not entirely inadequate. It covers the destination and idempotency, but leaves the parameter unexplained and lacks usage context, which is a noticeable gap given the low schema coverage.
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 compensate by explaining the 'owner_repo' parameter format or meaning. The word 'repo' only appears generically, with no hint that the parameter should be 'owner/repo' or similar.
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 (clone), the resource (a repo), and the destination (sandboxed workspace). It also differentiates itself from sibling tools like pull_latest and checkout_branch by specifying the sandboxed environment and idempotent 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 (e.g., pull_latest or list_branches). The description implies cloning a repo but doesn't state prerequisites, scenarios, 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?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only lists what is included but does not reveal whether the operation is read-only (the name 'generate' could even be slightly misleading), how the aggregation is performed (e.g., parallel calls, potential rate limits), or any edge cases like README truncation. This is a significant transparency gap for a composite 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 listing the exact components included in the summary. Every word earns its place, and there is no redundant information. The structure is front-loaded and easy to parse.
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 tool's complexity (aggregating seven data categories) and the absence of an output schema, the description is woefully incomplete. It does not explain what 'stats' means, whether the README is full or summarized, how the output is structured, or any dependencies on repository availability. The agent is left without crucial context for a tool that likely has a rich return value and multiple potential failure points.
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 has one parameter, owner_repo, with no description, and the tool description does not mention it at all, resulting in 0% schema description coverage. The parameter name is somewhat self-explanatory, but the description does not clarify the expected format (e.g., 'owner/repo') or provide any additional meaning beyond the schema title. This fails to compensate for the lack of schema documentation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool aggregates multiple repo data components (stats, contributors, languages, topics, license, latest release, README). This specific verb+resource combination distinguishes it from sibling tools that return individual pieces, making the 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 Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage as an all-in-one summary tool by listing all the data types it aggregates, but it does not explicitly say when to use it versus calling individual sibling tools like get_repo_stats or get_contributors. There is no explicit exclusion or alternative guidance, only the implied context of aggregation.
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 full burden. It exposes the useful behavior that renames are followed, which is a genuine behavioral trait. However, it does not mention the return format, pagination, or any potential performance caveats, leaving the agent without a complete picture.
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 single sentence is perfectly concise and front-loaded, stating the core purpose and adding a key nuance without unnecessary words. It earns its place 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?
For a simple two-parameter read-only tool, the description covers the main intent but omits details about the output shape (since no output schema exists) and does not clarify parameter formats. It is minimally viable but leaves room for improvement, especially given the lack of annotations.
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 has no parameter descriptions and the description gives no additional detail about filepath or repo_path format (e.g., absolute vs relative, whether filepath is relative to repo_path). With 0% schema description coverage, the description should compensate but does not.
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 returns commit history for a specific file, and the parenthetical 'follows renames' adds a distinctive behavior. It lacks an explicit verb but is specific enough to distinguish from broader tools like list_commits.
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 when a user needs a file's commit history, but it does not contrast with alternatives like list_commits or get_diff. There are no explicit 'when not to use' guidelines, so it remains at the 'implied usage' level.
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 responsibility for disclosing behavioral impact. Saying 'Run git pull' implies a mutating operation but does not mention potential side effects (e.g., local changes, merge conflicts, network requirements) or that the working directory may be updated. This is insufficient for a state-changing 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 short sentence that delivers the essential information without any fluff. It is front-loaded and 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 tool with one parameter, the description is minimally viable. It correctly identifies the operation and context, but given the absence of annotations and output schema, it could be more complete by noting potential failure modes or expectations (e.g., clean working tree). Still adequate for a straightforward command.
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 has one parameter (`repo_path`) with 0% description coverage, and the description does not explain what `repo_path` means or how to format it. The name is somewhat self-explanatory, but the description fails to add any semantic value beyond the schema field name.
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 (run `git pull`) and the target (an already-cloned repo), using a specific verb and resource. It distinguishes itself from sibling tools like `clone_repo` by explicitly scoping to already-cloned repositories.
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 phrase 'already-cloned repo' implies usage when the repository exists locally and needs updates. However, it does not explicitly mention when to use this tool over alternatives, nor does it provide exclusions or prerequisites beyond 'already-cloned.'
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 full responsibility for behavioral disclosure. It reveals only that the tool searches; it does not mention how a limit is applied, whether pagination exists, what fields are returned, rate limits, or authentication needs. This is a minimal description that leaves important runtime behavior undisclosed.
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 states the action and resource. There is no wasted text or redundancy; every word contributes to the core meaning. Appropriate for a simple search 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?
The tool has no output schema and no annotations, so the description must explain what the agent can expect. It only says 'search' and does not specify the result structure, the default result count, sorting behavior, or error conditions. For a tool that will return a list of repositories, this is incomplete context for an AI agent deciding whether and how to invoke it.
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?
Schema description coverage is 0%, so the description must compensate. It does explain that the query parameter represents a 'keyword,' but it adds no meaning about the limit parameter, its default of 5, or how results are ordered/filtered. The description provides only marginal insight beyond the raw parameter names.
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 and resource: 'Search GitHub for repositories matching a keyword.' It clearly distinguishes from sibling tools that operate on individual repositories (e.g., get_repo_info, list_pull_requests). The scope is unambiguous as a repository discovery/search action.
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 phrase 'matching a keyword' establishes a clear usage context for searching across repositories. While it does not explicitly name alternatives or exclusions, the tool's search-oriented purpose is clear and distinct from the repo-specific sibling tools. Some implicit guidance comes from the sibling list, but the description itself is adequate for basic use.
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 full burden. It transparently states that the tool lists all local and remote branches and highlights the current one, which implies a read-only operation. However, it does not explicitly disclose that it makes no changes, nor does it mention permissions or rate limits. For a simple list operation, this is adequate but lacking in 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 sentence, front-loaded with the action and resource, and contains no wasted words. It efficiently conveys the core functionality.
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?
This is a simple tool with one parameter and no output schema. The description sufficiently conveys what the tool does and what it returns (a list of branches). It does not explain the output format, but given the simplicity, the description is complete enough for an agent to understand its 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?
Schema description coverage is 0% (the only parameter 'repo_path' has no description in the schema), and the tool description does not elaborate on this parameter. While the parameter name is somewhat self-explanatory, the description fails to compensate for the missing schema documentation by not specifying the expected format or meaning of 'repo_path'.
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 ('List'), resource ('branches'), and scope ('all local and remote branches, plus the current one'). This distinguishes it from sibling tools like list_pull_requests or get_status. The mention of 'current one' adds useful specificity.
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 by the tool's purpose: an agent would call this when needing to view available branches. However, there is no explicit guidance about when to use this tool versus alternatives such as checkout_branch or compare_branches, nor any exclusions outlined. This meets the baseline for implied usage.
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?
With no annotations provided, the description reveals an important behavioral trait: requires admin and falls back to 'unknown' on failure. This adds meaningful context beyond the schema, although it does not describe the return format or any side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, well-structured sentence that conveys the core purpose and key caveat without redundancy. It is highly concise and front-loads the main action.
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 description covers the basic purpose and the admin/fallback behavior, but it lacks essential context such as the format of `owner_repo`, the exact structure of the returned status, and any additional constraints. For a simple tool with no output schema, this leaves some gaps.
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?
Schema description coverage is 0%, and the description does not explain the `owner_repo` parameter format or semantics beyond the name itself. The agent may not know whether to use 'owner/repo' or another format, so the description fails to compensate for the lack of schema details.
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 specifies the tool's function: retrieving branch protection status for the default branch. It is specific and distinct from sibling tools that deal with branches, diffs, or PRs, clearly indicating what resource and action are involved.
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?
It provides a contextual cue (requires admin) but does not explicitly state when to use this tool versus alternatives or when not to use it. The purpose is clear enough that an agent could infer usage, but there is no direct guidance on 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?
With no annotations, the description carries the full burden. It discloses the truncation behavior and return type, which is useful. However, it lacks details on error handling (e.g., missing README), truncation length, or any authentication requirements. For a read operation, this is adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence, front-loaded with the action 'Return', and every word adds value. There is no unnecessary fluff or repetition.
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 one-parameter tool with no output schema or annotations, the description is adequate but has gaps: it does not specify truncation limits, behavior for missing READMEs, or whether the output is raw markdown or plain text. It provides enough for basic use but is not fully self-contained.
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?
Schema description coverage is 0%, and the description does not explain the 'owner_repo' parameter. While the name is somewhat self-explanatory, the format (e.g., 'owner/repo' vs. separate fields) is not clarified, and the description adds no value 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 tool returns README text, with the specific purpose of enabling summarization. This distinguishes it from sibling tools that focus on other repository data, as none explicitly mention README retrieval.
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 phrase 'so the caller can summarize it' provides clear context for when to use this tool: when README content is needed for summarization. However, it does not explicitly mention alternatives or exclusions, but the purpose is distinct enough among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
