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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds that it returns 'all' approval comments and that they apply to 'a queue item or user file', but does not disclose behavior when both file_id and item_id are provided, or the return format. No contradiction with annotations.

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, concise sentence (10 words) with no redundancy. It front-loads the action and resource, making it easy to parse quickly.

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 simple operation and strong annotations, the description is minimally viable but incomplete. It correctly states what the tool returns and the target types, but does not clarify parameter selection or behavior when both/neither parameter is supplied. An agent might struggle to know whether to pass file_id, item_id, or both.

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 0%, so the description must compensate. It hints that file_id corresponds to 'user file' and item_id to 'queue item', but it does not clarify whether these are alternatives, optional, or how to choose between them. The description adds some meaning but leaves key invocation details ambiguous.

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 approval comments for a queue item or user file, using a specific verb ('Retrieve') and resource ('approval comments'). This distinguishes it from sibling tools like add_queue_comment, delete_queue_comment, and update_queue_comment, making the purpose unambiguous.

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_queue_item or inspect_printer_queue. There are no explicit exclusions or context cues beyond the basic function, leaving the agent to infer usage from the name and description.

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