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

Annotations already indicate this is a write operation (readOnlyHint=false) and non-destructive (destructiveHint=false). The description adds that authentication is required and that it records feedback, which is useful context. However, it does not disclose other behavioral traits like idempotency (already false in annotations) or potential side effects, so it provides only modest value beyond the 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 three short sentences, front-loaded with the primary purpose. Every sentence adds value: purpose, scope, and a key differentiation from sibling tools. No wasted words.

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 tool's complexity (7 parameters) and the excellent schema coverage, the description provides the essential context: what it does, when it applies, and how it differs from similar actions. It mentions authentication and the feedback nature. It lacks detail on the response format, but no output schema is present and for a write operation, this is acceptable. Overall, it is complete for an agent to invoke it correctly.

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 input schema has 100% coverage with descriptions for all parameters. The description redundantly mentions 'rating' and 'work quality' but does not add new meaning beyond the schema. The baseline is 3 because the schema does the heavy lifting.

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 action ('Add a review/rating') and the target resource ('for a completed task'). It explicitly distinguishes itself from approve/reject, which are sibling tools, by noting it 'records feedback' rather than approving or rejecting.

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 specifies the context of use ('for a completed task') and provides a clear differentiation from approve/reject by stating it is separate. It does not explicitly list alternative tools or edge cases where it should not be used, but the distinction is sufficient for an agent to select it appropriately.

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