verify_domain_claim

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

No annotations are provided, so the description carries the full burden. It does disclose the core behavior: a state-changing POST that triggers DNS verification. However, it does not say whether the operation is idempotent, what it returns, or what happens if the claim is already verified or not pending.

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?

One concise sentence front-loads the action and resource, with the endpoint parenthetically for precision. There is no filler or redundant restatement of schema fields.

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-required-parameter trigger with no output schema, the description provides the essential invocation details: action, endpoint, and precondition. It falls slightly short of full completeness because it does not mention how to confirm the verification result, especially since there is no output schema or annotation guidance.

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?

The schema already documents the only parameter, id, as 'The domain id' with 100% coverage. The description's URL path confirms id is the domain id but adds no further meaning beyond the schema, 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 uses a specific verb ('Trigger') and a specific resource ('DNS verification for a pending domain claim'), then reinforces it with the exact endpoint. This clearly distinguishes it from sibling tools like verify_domain and get_domain_claim by scoping the action to pending claims.

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 explicitly states the precondition ('pending domain claim') and frames the action as a trigger, so an agent knows this is not for general domain verification or for creating claims. It does not name alternative tools for checking claim status or initiating a claim, which prevents a full 5.

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