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

Annotations declare readOnlyHint and openWorldHint, and the description is consistent with both while adding genuine context: include_poc performs a live GitHub query, and exploit signal is described as live. It does not discuss latency, rate limits, or what happens when a CVE is unknown, but the live-network behavior of the optional flag is disclosed, which the annotations alone would not convey.

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 payload list is front-loaded in the first sentence and the Args block is terse. Every clause carries information, though the '(live)' qualifier appears twice and the second occurrence is redundant.

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?

With no output schema, the description correctly enumerates the returned fields so an agent knows what to expect, and annotations cover the read-only safety profile. Missing details are minor: no guidance on unknown-CVE behavior or the cost/latency of the live PoC query.

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?

Schema coverage is 0%, so the description carries the burden and largely meets it: cve_id gets an explicit format example ("CVE-2025-12345") and include_poc is explained as a live GitHub PoC lookup (default true, which the schema supplies). The only gap is that the description never says what happens if cve_id is malformed/unknown.

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?

States a specific verb (enrich) and resource (single CVE) and then enumerates exactly what intelligence is returned: CVSS, KEV, EPSS, CISA SSVC fields, P1-P4 priority with rationale, affected products/versions, and live exploit signal. The 'single CVE' scope cleanly separates it from corpus-wide siblings like search_vulns.

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?

Usage is implied: you call this to get the full picture on one known CVE id. The description does give the condition for the optional flag ('include_poc: also query GitHub for public PoC/exploit repos'), but never states when to prefer this over siblings such as search_vulns or verify_cve_claim, nor any prerequisite for having a valid CVE id.

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