Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/transilienceai/communitytools --skill cve-risk-score
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads cve-risk-score automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

CVE Risk Score

Fetch and display CVE risk scores from the National Vulnerability Database (NVD) whenever a CVE ID appears in conversation.

Trigger

This skill MUST be invoked automatically whenever a CVE ID (pattern CVE-YYYY-NNNNN) is mentioned by the user or discovered during research/scanning. Do not wait for explicit invocation.

Workflow

  1. Extract CVE IDs from the user's message or tool output (regex: CVE-\d{4}-\d{4,})

  2. Run the lookup script:

    python3 tools/nvd-lookup.py CVE-XXXX-XXXXX [CVE-YYYY-YYYYY ...]
    
  3. Present the results in a concise table format:

    CVE IDScoreSeverityCWEDescription
    CVE-XXXX-XXXXX9.8CRITICALCWE-79...
  4. Continue with the user's original task — the score lookup is supplementary context, not a blocking step.

Output Format

When presenting CVE risk scores inline, use this compact format:

CVE-2024-12345: 9.8 CRITICAL (CWE-79) — Remote code execution via ...

For multiple CVEs, use a markdown table.

Rules

  1. Always invoke — every CVE ID mentioned triggers a lookup. No exceptions.
  2. Non-blocking — fetch scores in parallel with other work when possible.
  3. Accurate data only — display exactly what NVD returns. Never estimate or fabricate scores.
  4. Graceful degradation — if NVD is unreachable or the CVE has no score yet, say so explicitly (e.g., "Not yet scored by NVD").
  5. Rate limiting — the script handles rate limits internally. For bulk lookups (5+), warn that NVD throttles unauthenticated requests.
  6. API key — if NVD_API_KEY is set in .env, the script uses it for higher rate limits.

Integration

This skill complements other skills:

  • cve-poc-generator: After seeing the risk score, the user may want a full PoC and report
  • reconnaissance / source-code-scanning: When these skills discover CVEs in dependencies, auto-lookup their scores
  • coordination: CVE scores inform priority and severity classification in findings
