coverage

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

With no annotations present, the description carries the full disclosure burden. It usefully reveals the returned content domains (coverage, refusals, licence and privacy terms), but says nothing about whether this is a read-only operation, whether output is static, or any auth/rate-limit characteristics.

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?

Two tight sentences with the resource scope front-loaded and the call trigger second. 'What this server covers and refuses' is slightly terse/oblique wording, but nothing is wasted.

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 parameterless metadata tool with no output schema, the description adequately conveys purpose, content domain, and when to invoke it. The only minor gap is that return format or structure is not hinted at, which is low-stakes here.

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 defines zero parameters, so per the rubric the baseline is 4. There are no parameters whose meaning the description needs to clarify, and no undocumented input is hidden.

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 names a specific, unusual resource: the server's coverage/refusal rules plus licence and privacy terms. That is clearly distinguishable from the sibling tools find_notices_near and read_notice, which retrieve notices rather than describe server scope.

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?

It gives an explicit trigger condition: 'Call this before answering questions about what kinds of notice can be found here.' That is a clear when-to-use instruction, though it does not state when-not to call it or name the siblings as alternatives.

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