Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden. It offers no auth requirements, rate-limit context, or whether the tool reaches out to an external service (NVD), and doesn't disclose anything about caching or failure modes for unknown CVE IDs.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded purpose sentence followed by a clean bullet list of returned fields. Efficient and easy to scan, though the bullet list is largely redundant with the output schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value enumeration in the description is redundant, and the field list is the only substantive content. The description lacks sibling differentiation and identifier-format guidance, leaving it minimally adequate given the tool's role in a crowded CVE-intelligence family.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the single cve_id parameter has no description anywhere. The description doesn't clarify the expected CVE identifier format, so an agent must infer it, which is a real gap despite the low parameter count.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Retrieve detailed vulnerability intelligence from NVD'), which names the source and scope. However, it never distinguishes itself from close siblings like get_complete_cve_intelligence or get_tenable_cloud_vulnerability, leaving the agent to guess which retrieval tool to pick.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use, when-not-to-use, or alternative guidance is provided. With siblings such as get_complete_cve_intelligence and search_security_intelligence present, an agent has no basis for choosing this tool over them.

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