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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the calculation method and data sources but lacks details on permissions, rate limits, error handling, or the nature of the output (e.g., format, interpretation). This is inadequate for a tool with potential complexity in scoring algorithms.

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 a single, efficient sentence that front-loads the core functionality. Every word earns its place by specifying the action, score range, and data sources without redundancy or unnecessary elaboration.

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's complexity (composite scoring from multiple sources) and no annotations, the description is minimal. However, the presence of an output schema mitigates the need to explain return values. It adequately covers the purpose but lacks behavioral and usage details, making it borderline complete.

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 input schema has 0% description coverage, and the description does not explain the 'cve_id' parameter beyond what's implied by the tool's purpose. It adds no syntax, format, or validation details. However, with only one parameter and a clear context (CVE-based risk calculation), the baseline is met without compensating for the coverage gap.

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 action ('calculate') and the resource ('composite 0-100 risk score'), specifying the data sources used (CVSS, EPSS, KEV, PoC). It distinguishes from siblings like 'get_epss_score' or 'parse_cvss' by combining multiple metrics into a composite score, though it doesn't explicitly name those alternatives.

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?

No explicit guidance on when to use this tool versus alternatives is provided. The description implies it's for calculating a comprehensive risk score, but it doesn't specify scenarios, prerequisites, or exclusions compared to sibling tools like 'compare_cves' or 'generate_vuln_report'.

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