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

Annotations already declare destructiveHint=true and idempotentHint=true, but the description adds substantial value beyond them: login requirement, explicit irreversibility, an instruction to confirm with the user before invoking, and a concrete failure case (organization_import_claim_unavailable for already-claimed items).

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?

Dense but front-loaded, using bracketed sections for login, chain, and pitfalls; every sentence carries information. The formatting is compact and slightly jargon-heavy, but there is no filler.

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 an irreversible single-parameter mutation with no output schema, the description covers auth, reversibility, user-confirmation, the surrounding workflow, and the error condition, so an agent has everything needed to invoke it safely.

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% with a single contactId parameter, so the schema already documents the input fully. The description reinforces what the id represents (pending claim item) but adds no syntax or format detail beyond the schema, matching the baseline-3 expectation.

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: mark a pending claim item as ignored, with parenthetical intent ('not me' / 'don't want to be listed by this org'). This clearly distinguishes it from the sibling claim_organization_profile, which does the opposite action on the same resource.

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 an explicit combo chain: list_my_organization_claims → user says 'this isn't me' → this tool → then claim_organization_profile for the remaining items. The triggering condition and the alternative are both stated, leaving nothing to inference.

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