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

Annotations declare the safety profile (readOnlyHint=false, idempotentHint=true, destructiveHint=false), and the description adds behavior annotations do not: it is login-gated, it publishes the product immediately upon claiming, and it passes first but is reviewed afterward. That immediate-publish side effect is the key non-obvious trait.

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 short, front-loaded block that leads with the login gate and side effect before the claim-code note; every clause carries information, though the parenthetical about admin/crawler pre-recorded products adds a little noise.

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 single-parameter mutation with annotations present and no output schema, the description covers the prerequisites (login), the trigger (claim code), and the outcome (instant publish), leaving little an agent needs to know before calling it.

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 the sole parameter claimCode is already described, so baseline is 3; the description goes slightly beyond by stating where the code comes from (admin-issued), giving the agent a hint about acceptable input provenance.

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 (认领) and resource (产品), plus the mechanism (认领码), and distinguishes the target from sibling claims like claim_creator_by_token and claim_organization_profile by specifying it re-parents an admin/crawler pre-recorded product onto the current account.

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?

It gives useful invocation context — login required and that the claim code is usually issued by an admin — but never explicitly contrasts this tool with alternative claim paths, so the agent must infer when to pick it over claim_creator_by_token.

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