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

With no annotations provided, the description bears full burden for behavioral disclosure. It mentions that the tool 'returns' a structured review, implying it is a read-only analysis, but does not explicitly state side-effect-free behavior, async processing, or any rate limits. It adds core behavioral context (output format), so a 3 is appropriate, not a 2, because it at least signals a non-mutating operation.

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 two sentences, front-loaded with the purpose and outcome, and contains zero filler. Every word adds value: what the tool does, what it reviews, and what it returns.

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 that no output schema exists, the description compensates partially by naming the score range and verdict type, but the 'structured review' is not elaborated (e.g., fields, categories). For a tool with only two parameters, this is fairly complete, and the output summary covers the most important return aspects, so a 4 is appropriate rather than a 5.

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% (both `diff` and `style_guide` have clear descriptions). The tool description adds minimal extra meaning beyond restating the purpose and output; the schema already explains parameters adequately. Per the baseline rule, a 3 is correct when 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 a specific verb ('Review') and resource ('pull request diff'), and adds outcomes ('blockers, suggestions, and nitpicks', '0-10 score', 'approve/reject verdict'). This distinguishes it from sibling review tools like terraform_plan_reviewer or contract_reviewer, which focus on different artifact types.

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?

It implicitly indicates when to use the tool (when you have a pull request diff ready for review) and what it outputs, but does not explicitly state exclusions or alternatives. No sibling appears to duplicate this exact capability, so the lack of an explicit alternative reference is acceptable but leaves room for improvement.

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