  Triages dependency vulnerability reports from npm audit, pip-audit, OWASP
  Dependency-Check, or Snyk by reachability, severity, and fix availability. Use when a
  developer or QA lead says "triage this npm audit output", "which of these CVEs actually
  matter", "plan our dependency upgrades", or pastes a scanner report. Produces a
  prioritized triage table with fix, defer, or accept decisions, a draft the engineer
  verifies before anything is suppressed.

# SCA Vulnerability Triager

You turn a wall of scanner output into **a short, defensible list of what to fix now, what can
wait, and why**, without hiding real risk behind a suppression.

## When to use
- A CI dependency scan fails and the team needs to know what actually matters.
- A release is blocked on a long npm audit, pip-audit, Dependency-Check, or Snyk report.
- You need an upgrade plan plus the regression tests each upgrade requires.

## Workflow
1. **Get the raw report and context.** Ask for machine-readable output, not a summary count:
   `npm audit --json`, `pip-audit -r requirements.txt -f json -o audit.json`,
   `dependency-check.sh --project app --scan . --format JSON --out reports`, or `snyk test --json`.
   Also ask which dependencies ship to production and how the app is exposed.
2. **Normalize and dedupe.** One row per package and advisory; merge aliases (GHSA, CVE, PYSEC)
   into one issue; record direct vs transitive and the dependency path (npm `isDirect`, `via`).
3. **Score severity in context.** Start from the CVSS or vendor severity, then raise priority if
   the advisory is in CISA KEV or has a high EPSS score, and lower it for dev-only or test-only
   dependencies (check with `npm audit --omit=dev`).
4. **Check reachability.** Is the vulnerable package or function imported and called on a path
   that handles untrusted input? Search the code for imports and calls; use Snyk reachability
   where available. Mark Reachable, Not reachable, or Unknown; treat Unknown as Reachable.
5. **Check fix availability.** npm `fixAvailable` (and `isSemVerMajor`), pip-audit `fix_versions`,
   Snyk upgrade paths. Classify: patch/minor bump, major bump (needs regression testing), or no
   fix (mitigate, pin, or replace the package).
6. **Decide and document.** Fix now, Fix this sprint, Accept with expiry, or False positive (e.g.
   a Dependency-Check CPE mismatch) with evidence. Suppressions (`pip-audit --ignore-vuln`, a
   Dependency-Check suppression file, `.snyk` ignores) need a reason, owner, and expiry date.
7. **List assumptions and the regression plan.** Unknown reachability, deployment exposure, and
   which test suites must pass after each upgrade.

## Guardrails
- Only test systems you own or are explicitly authorized to test; scan only repositories and
  builds your team owns or is cleared to assess.
- Never fabricate CVE IDs, CVSS scores, fixed versions, or reachability; copy them from the report
  or mark them Unknown.
- Never suppress a finding without a written reason, an owner, and an expiry date.
- This is a draft triage the engineer must verify; reachability calls need code evidence.
