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

Annotations already cover read-only, idempotency, and destructive hints, so the description adds domain-specific behavior: proof and current versions are rechecked, and a changed statement or proof invalidates the decision. This is valuable behavioral context 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?

Four tightly written sentences with the action and key constraint front-loaded. Every sentence contributes either scope, behavior, or sibling distinction without padding.

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 the core decision and revalidation behavior, and annotations/no output schema reduce the need for return-value detail. However, with low schema coverage on six required parameters, an agent still lacks enough guidance on challengeId, revision, and claimVersionId relationships.

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?

Only the code parameter gets added semantic meaning — it must come from the reviewer. With six required parameters and only 33% schema description coverage, the description does not clarify claimVersionId, revision, challengeId, or how they relate to the recheck 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?

States a specific verb (approve), resource (exact sourced business claim), and scope (only reviewer-supplied code). It explicitly distinguishes itself from library/dossier approval, giving an agent a clear functional target.

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?

Provides a clear precondition — use only the code explicitly supplied by the reviewer — and an exclusion against library/dossier approval. It does not spell out when to choose this over request_business_claim_approval or apply_business_claim_approval, but the context is otherwise clear.

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