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

No annotations are provided, so the description carries the full burden. It discloses the core behavior (parsing and explaining CVSS vectors) and supports multiple versions, but doesn't mention error handling, output format details, or performance characteristics like rate limits. It's adequate but lacks depth for a tool with no annotation coverage.

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 appropriately sized and front-loaded: the first sentence states the core purpose, followed by a structured 'Args:' section with a clear example. Every sentence earns its place with no wasted words.

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 moderate complexity (parsing structured CVSS data), no annotations, and an output schema exists (which handles return values), the description is reasonably complete. It covers purpose, usage, and parameter semantics adequately, though could benefit from more behavioral context like error cases.

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 description coverage is 0%, so the description must compensate. It adds meaningful semantics by explaining the 'vector' parameter as a CVSS vector string with an example (e.g., CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), which clarifies the expected format beyond the schema's basic string type. With only one parameter, this is sufficient.

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 with a specific verb ('parse and explain') and resource ('CVSS vector string'), including version coverage (v2, v3.x, v4.0). It distinguishes itself from sibling tools like 'calculate_risk_score' or 'lookup_cve' by focusing on vector interpretation rather than scoring, lookup, or other vulnerability analysis tasks.

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 clear context for when to use this tool: when you have a CVSS vector string to parse and explain. It doesn't explicitly state when not to use it or name alternatives, but the context is sufficiently clear given the specialized nature of CVSS vector parsing compared to sibling tools.

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