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

Annotations already declare this is a non-read-only, non-destructive, idempotent, closed-world mutation, so safety is covered. The description adds nothing beyond that: it never says what dismissing does to the recommendation (hide, suppress, deprioritize), whether it is reversible via recommendations.restore, or how it affects future recommendations. Only the schema's 'reason' text hints that it sharpens future recommendations.

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?

A single front-loaded sentence with no filler. It is efficient, though its brevity reflects missing content rather than deliberate economy.

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?

With full schema coverage, an output schema, and annotations covering the safety profile, the description does not need to restate parameters or returns. However, for a mutation that sits alongside block/restore/feedback siblings, the missing reversibility and 'which action to pick' context leaves a real gap.

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 100%, so both parameters are already documented, including the purpose of 'reason'. The description adds no format, constraints, or examples beyond the schema, which is the baseline expectation when the schema carries full param semantics.

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 verb and resource ('Dismiss a recommended company'), which is enough to distinguish it from list/get style siblings. It does not contrast with the near-neighbor actions recommendations.block or recommendations.restore, so the distinction is only partly carried by the name.

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?

There is no guidance on when to dismiss versus block, when to leave feedback, or that recommendations.restore is the undo path. The agent must infer the entire decision from sibling names alone.

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