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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions generating a 'patch priority ranking' which implies some processing logic, but doesn't describe how the ranking is determined, what data sources are used, whether it's a read-only analysis or has side effects, or any performance considerations. This leaves significant gaps for a tool that performs comparative analysis.

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 - a single sentence that efficiently communicates the core functionality. Every word earns its place with no redundancy or unnecessary elaboration. It's front-loaded with the main purpose.

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?

Given the tool has an output schema (which should document the ranking format), the description doesn't need to explain return values. However, for a comparative analysis tool with no annotations, the description should provide more context about the comparison methodology, data sources, or limitations. It's minimally adequate but leaves important questions unanswered.

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 has 0% description coverage for its single parameter 'cve_ids'. The description doesn't mention parameters at all, providing no additional semantic context beyond what the bare schema indicates. However, with only one parameter that's clearly an array of CVE identifiers, the baseline of 3 is appropriate as the schema structure is simple and self-explanatory.

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's purpose: comparing multiple CVEs by risk score and generating a patch priority ranking. It specifies the verb 'compare' and resource 'CVEs', but doesn't explicitly differentiate from sibling tools like 'lookup_cve' or 'search_cves' which might have overlapping functionality.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, context for comparison, or differentiate from siblings like 'get_epss_score' or 'parse_cvss' that might handle risk scoring aspects. The agent must infer usage from the purpose alone.

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