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

The annotations already declare this as a read-only, idempotent, non-destructive operation, so the description need not repeat safety details. It adds useful context that the returned record includes full sites, zones, and IP values, but it does not describe error behavior or access requirements.

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 very concise and front-loads the resource and returned contents. It is a fragment rather than a complete sentence, but there is no wasted wording.

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?

For a simple one-parameter getter with annotations and no output schema, the description gives a basic sense of what comes back. It is still thin on how the ID is used, what happens if the list is missing, and how this differs from listing all site lists.

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 has 100% description coverage and defines the sole parameter as the list ID. The description adds little beyond indicating that one site list is returned, so the schema remains the primary source of parameter meaning.

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 identifies a singular site list and says it includes full sites, zones, and IP values, which is clearer than the bare title. It implies retrieval of one record but does not explicitly differentiate this from the sibling list_site_lists tool.

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?

There is no explicit guidance on when to use this tool versus list_site_lists or when not to use it. The singular phrasing implies fetching one record, but no alternatives or conditions are stated.

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