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

With no annotations, the description carries the behavioral burden and does disclose meaningful traits: free, one per wallet, no payment, and prerequisite to purchase. However, it does not state what claiming actually returns, whether it consumes an entitlement, or other side effects beyond the one-time limit.

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?

The description is two short sentences with no wasted words. The key facts—free, one per wallet, no payment—are front-loaded, and the purchase prerequisite is stated immediately.

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 definition is adequate for selecting and invoking the tool given the rich schema and clear prerequisite, but there is no output schema and no description of the success response or deliverable format. An agent is left inferring what the claimed audit actually returns.

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%, and each parameter, especially the signature parameter, is already well documented with the exact message format and repeat-claim 409 behavior. The main description adds no additional parameter-level meaning, so the baseline of 3 applies.

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 clearly identifies the tool as a free one-per-wallet claim for a real SEO + link/OG audit, with the verb 'Claim' and a specific resource. It also explicitly differentiates from the paid sibling webcap_audit by saying 'Claim it before buying webcap_audit.'

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 gives a clear usage context: claim the free trial before purchasing webcap_audit, and notes the one-per-wallet limit. It does not enumerate exclusions such as what to do after already claiming, but the prerequisite relationship is explicit.

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