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

With no annotations provided, the description carries full burden. It effectively discloses the return format (unified diff, patches, addition/deletion stats) and notes the default limit of 50 files. However, it omits safety information (read-only status), authentication requirements, or error handling behavior.

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 efficient sentences with zero waste: usage trigger, return value description, and parameter requirements. Information is front-loaded and logically sequenced.

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?

Strong coverage given no output schema exists: describes return values (diff format, stats) and compensates by differentiating from siblings. Missing only edge-case handling and auth details, which would elevate it to 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 coverage is 100%, establishing baseline 3. The description lists required vs optional parameters but adds no semantic meaning beyond the schema (e.g., doesn't explain IID vs PR number, or provide format examples).

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?

Clearly states the tool retrieves 'actual code changes' (diffs) for review, distinguishing it from metadata-focused siblings. Specific about output format (unified diff, patches, stats). Loses one point because 'Use this when you need to review' frames purpose as usage context rather than direct functional definition.

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 defines when to use ('when you need to review the actual code changes') and explicitly names alternatives via 'See also: get_pull_request, comment_on_pull_request', clearly delineating this tool's scope from sibling tools.

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