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

The description adds the meaningful behavioral fact that no authentication is needed, which is not already captured by the readOnlyHint and destructiveHint annotations. This is valuable because many sibling tools require session logins, so the agent knows this call can be made directly.

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 two short sentences with no filler. The key authentication trait is stated first, followed by the core purpose, making it efficient and immediately scannable.

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 read-only list operation with only one optional parametercars and safety annotations already present, the description is largely complete. It conveys public access, the resource type, and the action, though it does not describe the shape of the returned resource list.

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?

Schema description coverage is 100%, and the single 'page' parameter is already documented in the input schema. The tool description does not add extra meaning about pagination behavior or page format, so it does not exceed the baseline for high schema coverage.

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 identifies the operation as 'List public NHIS resources/documents', with a specific verb and resource. However, it does not explicitly distinguish this tool from the closely named sibling nhis_edi__public__notices__list, so it falls short of full sibling differentiation.

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 notes that 'No credential or login required' but gives no explicit guidance on when to choose this tool over alternatives. It does not mention exclusions, preferred contexts, or how it relates to sibling list tools such as nhis_edi__public__notices__list.

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