approve_pull_request

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 merely states the action 'Approve' without explaining side effects, permissions, reversibility, or what the response contains, leaving the agent without essential safety or behavioral context.

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?

While the description is extremely short, it is under-specified rather than concise. The single sentence does not earn its place because it merely restates the tool name and provides no useful information, making it wasteful despite its brevity.

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 tool has a simple schema and an output schema, but the description is too brief to be complete. It does not explain what 'approving' entails, the conditions under which it can be performed, or any behavioral implications. The agent cannot confidently invoke this tool based solely on the description.

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 one parameter (pull_request_id) with 0% description coverage, and the description does not mention or explain the parameter at all. The description fails to compensate for the lack of schema metadata, leaving the agent with no additional semantic understanding beyond the type and title.

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 'Approve a pull request.' is a direct restatement of the tool name 'approve_pull_request' with no additional clarification. It is a tautology, adding no information beyond what the name already conveys.

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 like unapprove_pull_request or request_pull_request_changes. There is no mention of 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.
