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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the action ('Resolves') but doesn't clarify what 'resolves' entails (e.g., marking as closed, locking the thread, permissions required, side effects, or whether it's reversible). For a mutation tool with zero annotation coverage, this lacks critical behavioral details.

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 a single, direct sentence with no wasted words, efficiently conveying the core action. It's front-loaded with the verb and target, making it easy to parse quickly.

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 this is a mutation tool (implied by 'Resolves') with no annotations and no output schema, the description is insufficiently complete. It doesn't explain the outcome (e.g., what 'resolved' means, confirmation message format, or error conditions), leaving gaps in understanding the tool's full behavior and results.

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%, with all parameters clearly documented in the schema (e.g., repositoryId, pullRequestId, threadId, fullResponse). The description doesn't add any parameter-specific details beyond what the schema provides, so it meets the baseline of 3 for high schema coverage without extra value.

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 action ('Resolves') and target ('a specific comment thread on a pull request'), making the purpose immediately understandable. It doesn't explicitly distinguish from sibling tools like 'repo_reply_to_comment' or 'repo_update_pull_request', but the verb 'resolves' suggests a distinct operation focused on thread closure rather than modification or reply.

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?

No guidance is provided on when to use this tool versus alternatives, prerequisites (e.g., needing comment thread IDs from other tools), or contextual constraints. The description is purely functional without usage context, leaving the agent to infer when resolution is appropriate based on general knowledge.

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