pm_update_comment

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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It only indicates a PATCH operation (implying partial update) but does not mention what happens if the comment does not exist, required permissions, error conditions, or the response format. The minimal HTTP method hint is inadequate.

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 extremely short (one line), but this conciseness comes at the cost of essential information. It fails to provide a meaningful summary of the tool's purpose or behavior, making it under-specified rather than efficiently concise.

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 three parameters, 0% schema coverage, no annotations, and an existing output schema, the description is severely incomplete. It omits critical details about parameters, behavioral cues, and usage context, leaving the agent inadequately informed for correct tool selection and invocation.

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 does not explain any of the three parameters. The payload parameter (type: object, additionalProperties: true) is especially opaque, and no guidance is given on expected fields or usage of x_user_id. The description adds zero value beyond the schema.

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 is 'PATCH /comments/{comment_id}.' which essentially restates the HTTP method and endpoint without clarifying that the tool updates an existing comment's content or properties. This is nearly a tautology, providing minimal semantic value beyond the name.

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 given on when to use this tool versus its siblings (e.g., pm_create_comment, pm_delete_comment, pm_list_comments). The description lacks any context about prerequisites, alternatives, or appropriate scenarios.

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