reopen_pull_request_comment

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action without detailing side effects, permissions, or conditions (e.g., whether the thread must already be closed). This lacks the transparency expected for a mutation tool.

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, concise sentence with no unnecessary words. It is entirely front-loaded and efficient.

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?

The tool is simple with two params and an action that is self-explanatory, but the description lacks any guidance on usage, alternatives, or prerequisites. While the presence of an output schema may cover return values, the description still leaves gaps in context that could be filled with a brief note (e.g., 'Use this to reopen a resolved thread.').

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 0%, and the description provides no information about the parameters (pull_request_id, comment_id) beyond their names in the schema. The description fails to compensate for the lack of schema-level descriptions, so the agent gains no additional meaning from it.

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 'Reopen a pull request comment thread' uses a specific verb ('reopen') and resource ('pull request comment thread'), making it clear what the tool does. It also distinguishes itself from sibling tools like resolve_pull_request_comment, which performs the opposite action.

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?

The description implies its usage context—reopening a previously resolved comment thread—but does not explicitly state when to use it versus alternatives. No exclusions or prerequisites are mentioned, so guidance is only implicit rather than explicit.

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