Get Comment

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

With no annotations, the description must carry behavioral disclosure. 'Get' implies a non-mutating read, which is useful, but the description does not mention possible not-found behavior, required permissions, or what subset of comment data is returned. This is acceptable for a simple read but adds no extra behavioral context.

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?

A single, front-loaded sentence with no filler or redundancy. Every word adds semantic value.

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 (one required parameter) and an output schema exists, so the description need not spell out return values. The only missing context is explicit sibling differentiation and error behavior, already accounted for in other dimensions.

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 provides only a bare 'id' string with 0% description coverage. The tool description's 'by ID' tells the agent that this parameter is the comment identifier, compensating for the empty schema description. It does not specify ID format or source, so not a 5.

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?

Description states a precise action ('Get'), a specific resource ('comment'), and a clear scope ('single ... by ID'). This unambiguously differentiates it from siblings like get_all_comments, create_comment, and delete_comment.

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 phrase 'single comment by ID' provides clear context for when to call this tool: when the agent already has a comment ID and needs exactly one comment. It does not explicitly list exclusions or alternatives, so it stops short of a 5.

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