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

Beyond readOnlyHint=false and destructiveHint=false, the description discloses that dismissal affects visibility everywhere rather than merely naming a state transition. It does not clarify whether dismissal is reversible, whether the recommendation remains stored, or how already-dismissed or non-pending recommendations are handled.

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 single short sentence front-loads the action and immediately gives its purpose without filler. Its wording is economical and easy to parse.

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 one-parameter mutation, the target and visible outcome are enough for basic selection and invocation. However, with no output schema, the definition leaves the acknowledgment or result, reversibility, error behavior, and relationship to apply_recommendation unspecified.

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%, and recommendation_id is already documented, so the baseline score applies. The description adds only that the identified recommendation should be pending; it supplies no ID format, discovery method, or validation behavior.

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 pairs the verb "dismiss" with the resource "a pending recommendation" and states the intended effect: it "stops showing everywhere." This is clearer than a restatement of the name, but it does not explicitly distinguish dismissal from the sibling apply_recommendation.

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?

"Pending" narrows the eligible target, and the visibility outcome implies using the tool when a recommendation should be suppressed. There is no explicit when-not guidance or comparison to help an agent choose dismissal over applying the recommendation or leaving it pending.

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