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

With no annotations, the description carries the full burden. It correctly indicates this is a read operation ('Retrieve', 'returns'), mentions pagination, and lists filterable attributes. It does not disclose rate limits or error conditions, but the behavioral elements are well covered for a straightforward list endpoint.

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 extremely concise: two short paragraphs. The first sentence captures the core purpose, and the rest adds necessary context. No superfluous words, and it is well-structured for quick reading.

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 simplicity (6 optional params, no output schema), the description is complete. It covers the scope (own and shared accounts), pagination, and available filters. It could mention authentication implicitly, but 'authenticated client' suffices. No critical gaps.

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?

All 6 parameters have descriptions in the schema (100% coverage), so the description adds little extra meaning. It only restates that parameters can be used for filtering. Baseline 3 is appropriate; the description does not enhance understanding beyond the schema.

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 explicitly states the action ('Retrieve'), the resource ('list of websites'), and the types (main and addon). It clearly distinguishes from sibling tools like hosting_createWebsiteV1 or hosting_deploy* by focusing on listing. The verb 'retrieve' and scope (own and shared accounts) leave no ambiguity.

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 provides clear guidance on when to use the tool: to get a paginated list of websites. It mentions using query parameters for filtering, which is helpful. However, it does not explicitly state when not to use it or list alternatives among siblings. Nonetheless, the context is sufficient for an agent to decide.

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