What it does

Cve Risk Score is an agent skill from transilienceai/communitytools. Retrieve CVE risk scores from NVD. Auto-invoked whenever a CVE ID is mentioned to display CVSS score, severity, CWE, and description.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `reference/nvd-api-reference.md`).

It sits in Security, covering Vulnerability scanning. The repository describes itself as: Open-source Claude Code skills, agents, and slash commands for AI-powered penetration testing, bug bounty hunting, and security research. The licence is MIT.

When your agent uses it

  • Tasks that involve Vulnerability scanning

Example prompts

  • “/cve-risk-score”

Requirements

  • Python 3
  • A credential in NVD_API_KEY

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Extract CVE IDs from the user's message or tool output (regex: CVE-\d{4}-\d{4,})
  2. Run the lookup script
  3. Present the results in a concise table format
  4. Continue with the user's original task — the score lookup is supplementary context, not a blocking step.

What it can do on your machine

Read from SKILL.md and the folder at commit 95fdc12. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • NVD_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cve Risk Score loads about 565 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 264 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~565

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:46
    *API key** — if `NVD_API_KEY` is set in `.env`, the script uses it for higher rate limits.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Retrieve CVE risk scores from NVD. Auto-invoked whenever a CVE ID is mentioned to display CVSS score, severity, CWE, and description.

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:

    bash
    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
