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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description reinforces this with 'Writes nothing.' It adds context about what the tool reports, but it does not disclose much beyond the annotation and the high-level result.

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 sentences only, with the core purpose front-loaded and the safety/non-mutation note placed at the end. There is no filler or redundant explanation.

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 single-parameter read-only tool with an output schema and clear annotations, the description is largely sufficient. It could be more complete by explaining how competitors are selected, but this is a minor gap given the low complexity.

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 coverage is 100%, so the single applicationId parameter is already described as a UUID value wrapper. The description does not clarify what that applicationId refers to or how it connects to the competitor study, so it adds no extra meaning over the schema.

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 states a specific action (reads), a specific resource (competitors' trademark prosecutions), and a specific outcome (refusals drawn and wording that survived). It also distinguishes the tool from mutation-oriented siblings by adding 'Writes nothing.'

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 gives no explicit guidance on when to use this tool versus related tools such as trademark_run_clearance or trademark_get_clearance_report. It references competitors but does not explain the prerequisite or relationship to trademark_set_competitors.

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