cvss-score-extraction from cxcscmu/skilllearnbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add cxcscmu/skilllearnbench/cvss-score-extraction@git:20260424.d50cf5a

Pins git:20260424.d50cf5a in mdr.lock. Pin the fingerprint instead.

Extract CVSS scores from Trivy vulnerability data with proper source priority fallback (NVD > GHSA > RedHat).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# CVSS Score Extraction

## Source Priority

```
NVD (most authoritative) → GHSA → RedHat → N/A
```

Always prefer CVSS v3 scores. Fall back to v2 only if v3 unavailable.

## Implementation

```python
def get_cvss_score(vuln_data):
    """Extract best available CVSS v3 score. Returns float or 'N/A'."""
    cvss = vuln_data.get('CVSS', {})
    for source in ['nvd', 'ghsa', 'redhat']:
        if source in cvss:
            score = cvss[source].get('V3Score')
            if score is not None:
                return score
    return 'N/A'
```

## Trivy CVSS Data Format

```json
"CVSS": {
  "nvd": {
    "V2Score": 7.5,
    "V3Score": 9.8,
    "V3Vector": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"
  },
  "ghsa": {
    "V3Score": 9.8
  }
}
```

## Score Severity Mapping

| Score | Severity |
|-------|----------|
| 9.0-10.0 | CRITICAL |
| 7.0-8.9 | HIGH |
| 4.0-6.9 | MEDIUM |
| 0.1-3.9 | LOW |

How to install

The exact contents, by fingerprint

mdr add cxcscmu/skilllearnbench/cvss-score-extraction@sha256:3735b49cda9cdc53

The line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
