get_trending_repositories

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It does not mention that the tool is read-only, any rate limits, or data freshness, but the operation is inherently a safe read, which is implied by the purpose. For a simple fetch, this is minimally adequate.

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 three short sentences, but the first two essentially repeat the same information. It is concise but could be slightly more efficient. Still, it is front-loaded and easy to read.

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 tool has no parameters and no output schema, the description adequately explains the tool's purpose, sorting, and suitable use cases. It does not describe the output format or limitations, but for a simple trending list, this 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?

There are zero parameters, so the input schema is trivially complete. According to the guidelines, baseline 4 applies, and the description adds no additional parameter details, which is acceptable.

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 retrieves trending repositories for the current week, sorted by popularity. It explicitly mentions the verb 'get' and the resource 'trending repositories', distinguishing it from sibling tools like 'find_repositories' which likely handle general search.

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 explains it is suitable for understanding technology trends and popular projects, providing clear context for when to use it. While it doesn't explicitly mention when not to use or compare to alternatives, the use case is well-defined.

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