verify_domain

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

There are no annotations, so the description carries the full burden. It discloses that this is a POST action that triggers verification, but it does not explain what happens after triggering, whether verification is asynchronous, what failures may occur, or what the response represents. For an action-style tool, more behavioral detail is needed.

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 a single, well-structured sentence that front-loads the action and timing, with the endpoint included parenthetically. Every part earns its place, and there is no redundant wording.

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 simple one-parameter trigger with no output schemaiving, the description is largely complete: it names the action, the precondition, and the endpoint. It could be improved by noting whether verification is asynchronous and what the caller should expect in the response, but those are not critical for basic invocation.

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 single parameter 'id' is fully documented in the schema with 'The domain id.' The description does not add meaningful parameter-level detail beyond that, but because schema coverage is 100%, the baseline score of 3 is appropriate.

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 action ('trigger verification') and the resource ('a domain'), and adds a timing condition. It does not explicitly distinguish itself from the similar sibling 'verify_domain_claim', so it falls short of full sibling differentiation.

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 provides clear context for when to use the tool: after DNS records are in place. It does not explicitly name alternatives or exclusions, but the condition is specific enough to guide an agent toward the correct usage.

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