get_activity_comments

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

Without annotations, the description implies a read operation but does not explicitly state read-only behavior or disclose potential side effects. The description is minimally transparent, accurately reflecting that it retrieves data, but lacks details such as whether results are paginated or sorted.

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, clear sentence with no wasted words. It is front-loaded with the action and target, making it efficient for an agent to parse.

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 the tool's simplicity (one parameter, no nested objects, no output schema), the description is mostly complete. It states what the tool does and the parameter is documented. However, it lacks explicit clarification of the return format or any behavior when no comments exist.

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 schema already fully describes the single parameter 'activityId' with its required type and description. The tool description adds no additional meaning beyond the schema, so a baseline score of 3 is appropriate given 100% schema coverage.

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 tool retrieves all comments for an activity, using a specific verb 'Get' and resource 'comments'. It distinguishes itself from sibling tools like get_activity_details or get_activity_weather by focusing exclusively on comments.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites such as the activity needing to exist or whether the user must own the activity. An agent would have no context for appropriate usage.

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