create_domain

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

The description mentions creation and optional parameters, but does not detail side effects or behaviors beyond the annotations. Given annotations already mark it as non-read-only, the added value is moderate.

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 two sentences, front-loading the purpose and then detailing the structure. Every sentence adds value with no redundancy.

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 tool's complexity (one nested parameter) and lack of output schema, the description adequately covers input format and a key recommendation. It could be improved by mentioning output or success criteria, but it is largely sufficient.

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 input schema has a generic 'items' array with no property details. The description compensates by specifying that each dict contains 'name', optional 'hosted_dns' (default false), and optional 'create_default_addresses' (default true), which is essential for correct usage.

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 'Create domain(s)', indicating the action of creating one or more domains. It distinguishes from 'update_domain' or 'activate_domain' implicitly but could be more explicit.

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 includes a recommendation from Migadu regarding 'hosted_dns=False', providing usage context. However, it does not specify when to use this tool over alternatives like 'activate_domain' or contrast with update operations.

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