vulncheck_kev

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

No annotations are present, so the description carries the full burden. It mentions the extended coverage and included data types (exploit maturity, ransomware) but omits behavioral details such as error handling, rate limits, or authentication requirements. The information provided is helpful but incomplete for a fully transparent description.

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 extremely concise—two sentences with no filler or redundancy. Every word contributes to the purpose and key differentiators.

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 lookup tool with one parameter and no output schema, the description covers the core functionality and data enhancements. However, the absence of an output schema means it could be improved by describing the return format or fields more explicitly.

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 sole parameter 'cve' has 100% schema description coverage with a clear example. The tool description does not add additional semantic meaning beyond what the schema already provides, so baseline score of 3 is appropriate.

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 states the tool checks VulnCheck's extended KEV catalog for a given CVE, highlighting its differentiation from CISA KEV with 80% more entries and additional data (exploit maturity, ransomware association). This effectively distinguishes it from sibling tools like kev_check.

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 implies usage for comprehensive KEV lookups but does not explicitly state when to use it versus alternatives like kev_check or kev_search. No when-not-to-use or alternative recommendations are provided.

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