list_sites

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

No annotations are available, and the description merely states the tool lists sites without disclosing behavioral traits such as read-only nature, authentication requirements, or potential side effects. This provides almost no transparency beyond the tool's name.

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 that front-loads the core purpose. However, it is too brief to be fully informative, trading completeness for brevity.

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?

With no output schema and minimal description, the tool definition is severely incomplete. It lacks details on the return format, the effect of the environment parameter, and any behavioral context, making it insufficient for an agent to invoke correctly.

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 input schema has one optional parameter (environment) with 0% schema description coverage, and the description does not mention or explain this parameter at all. The agent cannot understand or correctly use the environment filter without additional context.

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 lists WordPress sites configured for this MCP, using a specific verb and resource. It is easily distinguishable from sibling tools like list_plugins or list_themes, which focus on different entities.

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?

No guidance is provided on when to use this tool versus alternatives such as get_site_info or other list tools. There is no mention of appropriate contexts or exclusions.

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