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

With no annotations provided, the description carries full burden and comprehensively lists all returned fields (iid, title, state, etc.) to compensate for the missing output schema. It also notes required parameters. However, it does not explicitly confirm this is read-only or mention authentication requirements/rate limits.

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?

Three tightly constructed sentences: use case first, return values second, requirements and cross-references third. Every sentence delivers unique value with no redundancy or filler, despite covering extensive information about returns and siblings.

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?

Despite lacking an output schema and annotations, the description achieves completeness by enumerating all 13+ returned data fields explicitly. With 100% schema coverage on 3 parameters and clear sibling differentiation, no critical gaps remain for a retrieval operation of this scope.

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?

Schema description coverage is 100%, establishing a baseline of 3. The description mentions that owner, name, and pull_iid are required, but this merely echoes the schema without adding semantic context, syntax examples, or validation rules beyond what the schema already provides.

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 tool retrieves 'full pull request context' using the specific verb 'get' plus resource 'pull request'. It distinguishes from siblings by referencing list_pull_requests, comment_on_pull_request, and merge_pull_request, clarifying this is for retrieval versus those actions.

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?

Explicitly states when to use ('when you need full pull request context before reviewing or merging') and names three specific alternatives via 'See also', providing clear guidance on when to use listing, commenting, or merging tools instead.

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