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 states it 'List[s]' data, implying a read-only operation, but lacks details on permissions, rate limits, data freshness, or output format. For a tool with 5 parameters and no annotation coverage, this is a significant gap in transparency.

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, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized and front-loaded, making it easy to parse quickly, with every word contributing to clarity.

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 complexity of 5 parameters, 0% schema coverage, no annotations, and no output schema, the description is incomplete. It doesn't explain parameter meanings, behavioral traits like data access or limitations, or what the output entails, making it inadequate for effective tool selection and invocation.

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 0%, so the description must compensate for undocumented parameters. It mentions 'stargazer countries/regions' but doesn't explain parameters like 'exclude_unknown', 'from', or 'to', leaving their purposes unclear. The description adds minimal value beyond the schema's property names, failing to address the coverage gap.

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 ('List') and resource ('stargazer countries/regions for a repository'), making the purpose specific and understandable. However, it doesn't explicitly differentiate from sibling tools like 'repo_stargazers_history' or 'repo_stargazers_organizations', which also involve stargazers but focus on different aspects, so it misses full sibling differentiation.

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. It doesn't mention scenarios like analyzing geographic distribution of stargazers, nor does it reference sibling tools such as 'repo_stargazers_history' for temporal data or 'repo_stargazers_organizations' for organizational insights, leaving usage context implied at best.

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