create_site

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

With no annotations provided, the description carries the full burden. It discloses that plan limits apply, which is useful, but it does not mention return values, idempotency, error handling, permissions, or potential side effects. The single sentence leaves most behavioral aspects undocumented.

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 one sentence, front-loaded with the verb, and contains no redundant words. It is appropriately sized for a simple create tool.

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 absence of an output schema and annotations, the description does not specify what the agent should expect after creation (e.g., the created site object or success message), nor does it address potential errors or prerequisites beyond plan limits. For a simple tool, it is minimally sufficient but has clear gaps in outcome and failure behavior.

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 schema already documents the only parameter 'url' as 'Site URL' (100% coverage), so the description adds no new parameter information. No format, uniqueness, or validation details are provided beyond the schema. The baseline of 3 is appropriate since the schema does the heavy lifting.

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 uses the specific verb 'Create' and identifies the resource 'site', clearly stating the action. It distinguishes from sibling tools like list_sites, update_site, and delete_site by focusing on creation. The parenthetical 'subject to plan limits' adds a relevant constraint without confusing the purpose.

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 usage (creating a site) but provides no explicit guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites. The plan-limit note hints at a condition but doesn't explain how to handle it or when to avoid the tool. Usage is inferred from the name and verb rather than stated.

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