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

No annotations are provided, and the description offers zero behavioral information such as permissions needed, rate limits, or side effects. The minimal description does not compensate for the lack of annotations.

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?

One sentence that is direct and to the point. However, it could be improved by adding a bit more context without being 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?

Missing critical details: no output schema, no explanation of required permissions, unclear 'body' structure. For a mutation tool, the description is insufficiently complete.

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 description adds no meaning beyond the input schema, which itself has trivial property descriptions ('gist_id', 'Request body (JSON object)'). The 'body' object has no defined properties, and the description does not clarify what it should contain.

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 'Create a gist comment' uses a specific verb 'Create' and clearly identifies the resource 'gist comment'. It distinguishes from sibling tools like delete, update, get, and list comments, so purpose is unambiguous.

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 alternative comment operations. It does not specify any context, prerequisites, or exclusions.

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