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

Annotations already establish readOnlyHint=false, idempotentHint=true, and destructiveHint=false. The description adds genuinely new behavioral context beyond those annotations: the login requirement, the post-then-review model (先过后审), and the consequential side effect that claiming immediately publishes the product. No contradiction with the annotations exists.

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 compact sentence that front-loads the login prerequisite, then states the action, the immediate-publish consequence, and the code source. Every clause earns its place and nothing repeats what the schema or annotations already provide.

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 one-parameter tool with no output schema, the description covers the auth prerequisite, target resource type, the side effect of immediate publication, and code provenance. It omits failure behavior (e.g., invalid or already-used codes), which is a minor gap given the tool's simple surface area.

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 claimCode parameter is already described as 认领码. The description adds only marginal value beyond the schema by noting that the code is generally issued by admins, which documents provenance but not format, validation, or failure 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?

The description states a specific verb (认领/claim), resource (a product pre-recorded by admin or crawler), and mechanism (claim code) that binds the product to the current account. It is clearly about products and claim codes, but it does not explicitly contrast with the close sibling claim_creator_by_token, leaving sibling differentiation implicit rather than stated.

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?

The description conveys clear usage context: login is required, the claim code is generally issued by an admin, and the target product is pre-recorded rather than user-created. It does not provide explicit when-not guidance or name alternatives such as claim_creator_by_token or create_product, so exclusions are left to inference.

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