get_user_profile

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

The word 'Get' and the qualifier 'public' imply a read-only operation, but the description does not explicitly state that it does not modify data, whether authentication is required, or any rate-limit considerations. Without annotations, the behavioral burden falls on this text.

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?

A single sentence with no filler. The core purpose and targeted resource are articulated first, making it immediately scannable for an agent.

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 definition is largely complete for a simple single-parameter lookup: the output schema exists and can cover return details, and the description gives enough selection and invocation context. Slightly more detail about auth or what 'profile information' includes would push it higher.

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, and the description does not directly document the 'username' parameter. However, the parameter name is semantically obvious, and 'for a GitHub user' adds enough context to understand the parameter is a GitHub username.

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?

Uses a specific verb and resource: 'Get public profile information for a GitHub user.' It clearly distinguishes itself from sibling tools focused on repositories, files, commits, issues, and pull requests.

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?

No guidance on when to use this tool versus alternatives. It does not mention when not to use it or point to more appropriate sibling tools for repository-related user data.

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