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

The annotations already declare a safe read-only, idempotent, non-destructive operation, so the safety profile is covered. The only behavioral insight added is that comments support threaded replies via parent_id, which describes the returned structure but is not itself a filter parameter here, adding moderate value without covering pagination or ordering behavior.

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?

Two short sentences with the core purpose front-loaded and zero filler. It is efficient, though arguably too terse given the unexploited room for usage and scope guidance.

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 list tool whose annotations cover the safety profile and whose schema fully documents its three parameters, the description is minimally adequate. It leaves gaps around filtering expectations and pagination behavior, but with no output schema and a simple signature the burden is limited.

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 100%, so page, per_page, and project_id are already fully documented with defaults and limits. The description adds no further parameter meaning, so the baseline of 3 applies.

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?

States a specific verb and resource ('List comments on projects'), which is clear and unambiguous. However, it does not differentiate from closely-named siblings like list_asset_comments or list_work_order_comments, leaving the agent to infer the scope from the name alone.

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 offers no when-to-use guidance, no alternatives, and no prerequisites. It does not say when to prefer this over get_project_comment or create_project_comment, nor when filtering by project_id is expected.

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