verify_domain

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

No annotations are provided, so the description must disclose behavior. It states 'Trigger DNS verification' but does not explain if it is synchronous, idempotent, or error handling for missing records. Adequate but lacks depth.

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?

Very concise, three short sentences plus parameter listing. The 'Args:' header is slightly redundant but not harmful. Effectively front-loaded with key instructions.

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?

With an output schema present, the description covers the essential usage: prerequisite steps and parameter source. It lacks details on errors or async nature, but for a simple trigger, it is reasonably complete.

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 coverage is 0%, so description adds meaning. It explains that 'domain_id' comes from 'list_domains', providing source context. However, it could specify format or constraints (e.g., required format).

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 the tool triggers DNS verification for a domain, using a specific verb and resource. It distinguishes itself from siblings like 'get_domain_records' and 'create_domain' by focusing on the verification step.

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?

Explicitly instructs to call after adding DNS records and to use 'get_domain_records' first for prerequisite records. This provides clear when-to-use and what-to-do-before guidance, differentiating it from other tools.

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