Suggest a subdomain from a prompt

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

Annotations provide readOnlyHint=true, but description does not clarify that it's a read-only operation (it calls it a 'generation', which could imply state change). No details on idempotency (annotations indicate idempotentHint=false, but behavior not explained) or whether slug is guaranteed unique.

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?

Single sentence, concise and front-loaded with action verb. No wasted words, but could benefit from brief additional usage context.

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 simplicity of tool (one param, no output schema), description covers basic purpose and input. However, missing details on output format (what does the slug look like?), uniqueness guarantee, and integration with check_subdomain make it slightly incomplete.

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?

With only one parameter, schema coverage is 0%, but description adds meaning: 'prompt' is a natural-language description for generating a slug. Clearly states input is a natural-language prompt, which schema does not convey.

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 generates a friendly subdomain slug from a natural-language prompt, using verbs 'generate' and 'suggest'. It distinguishes from sibling 'check_subdomain' by focusing on generation rather than validation.

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 implies use when needing a subdomain suggestion, but lacks explicit guidance on when to use vs alternatives like manual naming or check_subdomain. No mention of prerequisites or constraints.

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