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

With no annotations provided, the description carries full burden and successfully discloses return format ('JSON array of PR objects with number, title, state...') and default pagination behavior ('default 100'). Lacks explicit safety declaration (read-only), though implied by 'check/review' verbs.

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?

Four well-structured sentences covering use case, return value, parameters, and sibling references. No redundant information; every sentence provides distinct value. Appropriate length for the tool's complexity.

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 no output schema and no annotations, the description adequately compensates by detailing the return structure and fields. Workflow context (checking before creating) is present. Minor gap: doesn't mention if results are sorted or filterable beyond the limit parameter.

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?

Compensates effectively for 0% schema description coverage by documenting all 3 parameters: identifies required fields ('owner', 'name') and optional field with default ('limit' default 100). Minor gap: doesn't explain semantic meaning of 'owner'/'name' (repository owner/repo name), but requirement status and defaults are clearly specified.

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?

States specific actions ('check existing PRs', 'review PR status') and distinguishes from siblings by contrasting with 'creating a new one' and referencing 'create_pull_request' and 'merge_pull_request' in the see-also section. Clearly identifies the resource (PRs) and scope (existing vs new).

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 to check existing PRs before creating a new one') and provides clear alternatives via 'See also: create_pull_request, merge_pull_request'. Establishes workflow context (check before create) that guides agent decision-making.

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