Generate Free Subdomain

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

With no annotations, the description carries the full burden of behavioral disclosure. It conveys that a subdomain is generated, but does not disclose consequences (e.g., is it permanent? any limits?), return format, or whether it consumes any quota. This is minimal transparency for a creation tool.

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 a single, concise sentence with no redundant phrasing. It efficiently states the core action and purpose without wasted words.

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 no output schema and no annotations, the description is too brief to fully inform an agent. It does not explain what the resulting subdomain format is, whether it requires any prior setup, or what the response contains. This is inadequate for a tool with zero structured context.

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 tool has zero parameters, so the baseline score is 4. The description does not need to explain parameter meaning since none exist, and the empty schema fully covers the input structure.

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 'Generate a free subdomain for testing' clearly identifies the action (generate), resource (free subdomain), and purpose (testing). It distinguishes from sibling tools like hosting_subdomains_create by specifying 'free' and 'testing', though it does not explicitly explain the difference from a regular subdomain creation.

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 gives only a vague usage context ('testing') but does not provide explicit guidance on when to use this tool versus alternatives like hosting_subdomains_create. It lacks any mention of when not to use it or what prerequisites exist (e.g., an active hosting plan).

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