getTrendingRepos

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get trending/popular repositories' and does not mention authentication, rate limits, the criteria for 'trending', or any side effects. For a tool with no annotation coverage, this is a significant gap.

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 short phrase, which is concise but under-specified. It earns its place as a clear label, but it could easily include a sentence about usage or parameters without becoming verbose.

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

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

The tool has no annotations, no output schema, and only a minimal one-line description. The meaning of the relays parameter and the expected response shape are left undocumented, making the context incomplete for an agent.

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

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

The schema already provides descriptions for limit and timeRange, but relays lacks a description, and the tool description does not compensate. With 67% schema coverage (not high), the description should have clarified the missing parameter, but it adds no parameter information at all.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Get trending/popular repositories' uses a specific verb ('Get') and resource ('repositories'), and the 'trending' qualifier helps distinguish it from sibling repo-listing tools like listRepos or exploreRepos. However, 'popular' is somewhat vague, and no further details are given about what constitutes trending or popular.

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 this tool is for when you want trending/popular repositories, but it provides no explicit guidance on when to use it versus the many sibling tools (e.g., listRepos, searchRepos, exploreRepos). No alternatives or exclusions are mentioned.

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