Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions what fields are returned (repo name, description, stars, language, topics) but doesn't cover important aspects like rate limits, authentication requirements, pagination behavior, or error conditions for a search API tool.

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 appropriately brief (two sentences) and front-loaded with the core purpose. Every sentence adds value: the first states what the tool does, the second describes the return format.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a search tool with 2 parameters, no annotations, and no output schema, the description is insufficient. It doesn't cover authentication needs, rate limits, error handling, or how results are sorted/filtered. The return format is mentioned but without schema details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50% (only 'query' has a description). The description doesn't add any parameter-specific information beyond what's in the schema. It doesn't explain search query syntax, result ordering, or what 'num_results' default of 10 means in practice.

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 ('Search GitHub repositories') and the resource ('GitHub repositories'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'search_google' or 'search_web' beyond mentioning GitHub specifically.

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 sibling search tools (compare_engines, search_academic, search_google, search_web). It mentions GitHub but doesn't explain why one would choose GitHub search over other search options.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
