listSites

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

No annotations are provided, and the description only says 'List Netlify sites' without disclosing any behavioral traits such as pagination, read-only guarantees, rate limits, or response format. The verb 'list' implies a read operation, but no explicit transparency is given.

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 directly states the purpose. It is appropriately short and front-loaded, with no filler, though it omits some contextual detail that could be valuable.

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 annotations, the description should explain return values or operational details. It doesn't mention the filter parameter, response shape, or any behavior beyond listing. For a simple tool it is workable, but it lacks completeness for an agent to fully understand invocation and output.

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 fully describes the only parameter 'filter' with its enum values and description, achieving 100% schema coverage. The description adds no additional parameter meaning, so the baseline score of 3 applies.

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 'List Netlify sites' clearly states the action (list) and resource (Netlify sites). It distinguishes itself from siblings by indicating a plural list operation versus create/get/delete actions.

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 about when to use this tool versus alternatives like getSite or when not to use it. There is no mention of context or exclusions, leaving the agent to infer typical list usage.

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