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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether the operation is read-only, requires authentication, has rate limits, or what the output resembles. 'Validation' hints at a lookup but does not explicitly cover side effects or prerequisites.

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 short, which is concise, but it is a fragment lacking a clear subject-verb-object structure. It fronts the domain terms but fails to provide a self-contained explanation, making it under-specified rather than effectively concise.

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 one parameter, no annotations, and 0% schema coverage, the description needs to explain what input is expected and how the tool behaves. It does neither, leaving the agent reliant on the output schema for return structure but with no guidance for calling the tool 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 single parameter `q` is completely undocumented in both the schema and the description. The description mentions 'covering prefix' but never links it to the input parameter, so an agent cannot determine what value to supply.

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 states the tool performs RPKI/ROA route-origin validation for a covering prefix, which is a specific domain action. However, it does not clearly articulate what the input should be or how it differs from other routing tools like asnprefixes or bgphistory, leaving some ambiguity.

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 guidance on when to use this tool versus alternatives such as asnprefixes or bgphistory. The description does not mention any exclusions or alternative tools, so the agent must infer usage context from the tool name alone.

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