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

Annotations already declare readOnlyHint=true, so the safe read nature is established. The description adds the REST endpoint, but no additional behavioral details such as pagination, ordering, or whether replies are included. Overall, it provides only marginal extra context beyond the annotation.

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 two short sentences, immediately front-loaded with the action. The REST endpoint line adds useful reference without redundancy. No wasted words.

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 simple read-only tool with one parameter, the description covers the core purpose. However, it doesn't mention response shape or potential limitations like pagination, which an agent might need. Given the lack of output schema, a bit more context could be added, but it's still mostly complete.

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 fully documents the only parameter, task_id, with a clear description. The tool description does not add further semantic meaning beyond what the schema provides. Following the rubric, high schema coverage yields a baseline of 3.

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 'Get the comments on a task,' using a specific verb and resource. It distinguishes from sibling tools like get_task and get_list_comments by focusing on task-specific comments. The REST endpoint reinforces the scope.

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 does not explicitly state when to use this tool over alternatives like get_list_comments. It only provides the purpose, which implies usage when a task_id is available. No exclusions or alternative recommendations are given, so the guidance is minimal.

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