devops_pull_request_create_comment

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

While the description indicates a write operation ('create') and annotations confirm non-read-only, it does not disclose additional behavioral details such as side effects, required permissions, or response characteristics. An output schema exists but is not referenced.

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 sentence of 11 words, conveying the essential purpose without any fluff. Every word earns its place.

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 comprehensive schema descriptions and existence of an output schema, the description covers the core purpose adequately. It could mention the response or side effects, but for a mutation tool, it is sufficiently 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 input schema provides descriptions for all 5 parameters (100% coverage), so the description adds little beyond clarifying that the comment is 'initial' for a new thread. The baseline of 3 is appropriate as the schema does the heavy lifting.

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 action (create), resource (a new thread with initial comment), and context (in specified pull request). It effectively distinguishes from sibling tools like reply or update comments.

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 creating a new comment thread but does not provide explicit guidance on when to use this tool versus replying to an existing thread or other alternatives. No exclusions or context are given.

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