get_comments_by_id

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the description adds little behavioral context beyond the existing safety profile. It does not mention authentication, error behavior, response shape, or any call-relevant side effects.

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 short and front-loaded with the core purpose, followed by the endpoint and parameter documentation. Every line adds useful information without waste.

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?

For a single-parameter read-only getter with an output schema and strong safety annotations, the description is sufficiently complete. It states what is fetched, how to call it, and what the id parameter means, leaving no critical gap for correct 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?

The input schema provides only a string named 'id' with no description, so the description carries the semantic burden. 'The id/slug of the resource' usefully clarifies that the parameter accepts either an ID or a slug, which is meaningful for a one-parameter tool.

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 states a specific verb and resource: 'Get a comment or reply.' The endpoint path GET /comments/{id} and the 'or reply' clarification distinguish this single-resource fetch from related comment endpoints like replies lists or reaction summaries.

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 such as get_comments_by_id_replies or get_comments_recent_by_comment_type_by_type. The description only restates the operation without giving context, prerequisites, or exclusions.

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