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

Annotations already mark destructiveHint=true, and the description adds meaningful behavioral detail by disclosing the overwrite behavior and the state precondition. This goes beyond the structured annotations without contradicting them.

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?

Three concise sentences, with the main purpose first and every sentence adding a meaningful constraint or parameter detail. No filler or redundancy.

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 description covers purpose, parameter semantics, valid timing, and destructive overwrite behavior. An output schema exists, so return values do not need to be explained. Nothing essential is missing for correct invocation.

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?

With 0% schema description coverage, the description compensates well by defining rating's allowed values ('good' or 'bad') and comment's optional free-text nature. ticket_id is only implied through the phrase 'ticket is completed or failed', leaving a small gap, but the most error-prone parameters are clarified.

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 clear action — leaving feedback on a finished task — and distinguishes it from siblings by tying it to ticket completion/failure and overwrite semantics. No other sibling is about feedback, so there is no ambiguity.

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?

It explicitly restricts usage to tickets that are completed or failed and warns that calling again overwrites the previous rating/note. It does not name alternatives, but none of the siblings is a feedback tool, so the timing and idempotency guidance is sufficient.

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