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

No annotations are provided, so the description carries the full burden. 'Return' communicates a read-only info operation and the description lists the output dimensions (scope, coverage, provenance, counts), which is useful. It does not explicitly state side-effect-freeness, freshness, auth requirements, or whether the catalog is filtered differently from other CVE tools, but it does not contradict annotations and is a straightforward retrieval.

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?

A single, front-loaded sentence names the action, resource, and output content without wasted wording. It is appropriately sized for a zero-parameter info tool.

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 parameters and an output schema present, the description covers the agent's needs: it names exactly what catalog aspects will be returned. No additional caveats or return-value detail is necessary for this simple retrieval tool.

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 tool has zero parameters, so there is no parameter semantics burden on the description. Baseline 4 applies because there is nothing for the description to clarify about inputs.

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 begins with the specific action 'Return' and identifies a concrete resource: the Medium/High/Critical CVE catalog's scope, coverage, provenance, and counts. This clearly distinguishes it from sibling tools like recipes_cve_get and recipes_cve_search, which target individual CVEs or search results rather than catalog-level metadata.

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 when-to-use or when-not-to-use statement and no mention of alternative tools. However, the phrasing 'complete ... catalog scope, coverage, provenance, and counts' implies this is the catalog-wide overview tool, so a capable agent can infer usage from context, but the contrast with cve_get/cve_search is left implicit.

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