agency-hosting_listDomainsV1

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

No annotations are provided, and the description does not explicitly mention that the operation is read-only or free of side effects. It only says it returns a list, which implies no mutations but lacks explicit behavioral details such as pagination limits or error behavior.

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 concise, consisting of two sentences that clearly state the primary purpose first and then a usage tip. It is well-structured and front-loaded, with no redundant information.

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 lack of an output schema, the description provides a reasonable overview of what the tool does and the available filter. However, it does not specify the response structure or any pagination details beyond 'paginated', which limits completeness. The tool is simple enough that the description is adequate but not fully comprehensive.

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?

Each parameter has a description in the schema, but they are generic (e.g., 'Page number', 'Number of items per page'), and the website_uuids description merely restates the name ('Filter by website UIDs') without adding format or constraints. This adds some meaning but not comprehensive semantics.

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 returns a paginated list of domains for Agency Plan websites, which distinguishes it from other domain-related tools like domains_getDomainListV1. It is specific about the scope (Agency Plan websites) and the authenticated client's access.

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 a usage hint about using the website_uuids filter to narrow results, which indicates a use case. However, it does not explicitly compare this tool to sibling tools or state when to prefer this over alternatives, so the guidance is implied rather than explicit.

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