get_developer_profile

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

No annotations are provided, so the description must convey behavioral traits. It details the return content including an activity score with per-dimension breakdown. However, it does not mention potential side effects (none expected), authentication needs, or rate limits, which would increase 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 efficiently structured: a one-sentence purpose, a bulleted list of return contents, and an Args line. Every sentence provides value with no redundancy or clutter.

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 an output schema and the description already enumerates the returned data (languages, stars, commit activity, etc.), the description is complete. It includes the unique activity score range and breakdown, covering all key aspects without needing further elaboration.

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 has 0% description coverage, but the description explicitly lists the 'username' parameter with a clear explanation: 'GitHub username to analyze'. This adds essential meaning beyond the type 'string' in the schema.

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 starts with 'Get enriched GitHub developer profile with activity scoring', which is a specific verb+resource combination. It clearly distinguishes from sibling tools like 'search_developers' (search) and 'rank_candidates' (ranking), as this tool focuses on a single enriched profile.

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 usage for individual developer profiles by listing single username and rich return data. While no explicit 'when to use vs alternatives' is stated, the context from sibling tool names suggests this is for detailed single-profile analysis, not for bulk or comparative operations.

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