verify_domain

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only says 'verify domain.' It does not state whether verification is read-only, whether it modifies domain state, whether it has prerequisites, or what a successful or failed verification means.

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 one-sentence description is front-loaded with the core verb and resource and contains no filler or redundancy. It is concise, though extremely thin.

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?

An output schema exists, so return-value documentation is less critical, but the description still leaves essential invocation context missing: what methods are available, what zoid refers to, and how this differs from other domain verification tools. It is not complete enough for reliable autonomous use.

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 0% and the description adds almost no parameter meaning. It alludes to a method but does not document valid mode values, the meaning of zoid, or any domain_name formatting requirements. The required parameters are effectively undocumented.

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 identifies the action ('Verify domain') and mentions a method parameter, but 'using specified method' is vague and does not explain what kind of verification is performed. It also does not distinguish this generic verification from the more specific sibling tools such as verify_mx_record, verify_spf_record, and verify_dkim_key.

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?

No guidance is given on when to call verify_domain versus add_domain, get_domain_details, verify_mx_record, verify_spf_record, or verify_dkim_key. The agent is left to infer the intended selection criteria from the tool name alone.

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