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

Annotations already declare this is a mutation (readOnlyHint=false) that is non-destructive and not open-world. The description adds genuinely useful operational context — the $0.05 cost and API key requirement — but says nothing about whether a dismissal is reversible, what happens to the underlying entity record, or whether the pending item can be restored.

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?

One sentence with the action front-loaded and cost/auth constraints tucked into a trailing parenthetical. Nothing wasted, nothing buried.

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?

An output schema exists, so return values need not be described, and the cost/auth note covers operations. Still missing is the consequence of dismissal (irreversibility, effect on the entity) and any routing guidance among the three clarification-related siblings, which leaves the definition thin for a paid mutation tool.

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 only 50%: request_id and idempotency_key are documented in the schema, but clarification_id (the sole required param) and reason are bare. The description mentions clarification types but does not explain what clarification_id references or what reason is used for, so it fails to compensate for the coverage gap.

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?

States a specific verb and resource ('Dismiss a pending entity clarification') and gives a concrete example of the clarification type ('not_person, etc.'). It is distinguishable from resolve_clarification and bulk_dismiss_clarifications by implication, but never names those siblings or draws the boundary explicitly.

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?

Only the word 'pending' hints at when this applies. There is no guidance on when to dismiss rather than resolve a clarification, no mention of bulk_dismiss_clarifications for multiple items, and no stated preconditions beyond an API key.

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