verify_domain

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

With no annotations, the description must carry behavioral disclosure. It mentions checking DNS records, but does not state side effects, async behavior, failure modes, whether ownership gets persisted, or what happens after verification. The access note is operational context, not behavioral transparency.

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 core description is short and front-loaded, with the access note placed after. The wording has slight redundancy ('Trigger domain verification' and 'Checks DNS records...'), but overall it is compact and structured.

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?

Given the large sibling set with many similar domain-verification tools, the description lacks crucial routing information. It does not explain how verify_domain differs from start_domain_verification, check_domain_verification, or verify_domain_with_credentials, and there is no output schema to clarify the response.

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 the single param 'id' is already documented as 'Domain ID to verify'. The description adds no extra meaning to the parameter, so 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 states a specific action ('Trigger domain verification') and resource ('domain'), and explains the goal ('confirm domain ownership'). However, it does not distinguish itself from closely named siblings like start_domain_verification, check_domain_verification, or verify_domain_with_credentials.

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 provides authentication prerequisites but no guidance on when to use this tool versus the many domain-related alternatives. It neither names competing tools nor gives selection criteria, so an agent cannot confidently choose it over similar siblings.

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