Security Skill

Purpose: Run repeatable security checks across code, scripts, hooks, and release gates.

Use this skill when you need deterministic security validation before merge/release, or recurring scheduled checks.

Quick Start

/security                      # quick security gate
/security --full               # full gate with test-inclusive toolchain checks
/security --release            # full gate for release readiness
/security --json               # machine-readable report output

Execution Contract

1) Pre-PR (fast)

Run quick gate:

scripts/security-gate.sh --mode quick

Expected behavior:

• Fails on high/critical findings from available scanners.
• Writes artifacts under .agents/security/<run-id>/.

2) Pre-Release (strict)

Run full gate:

scripts/security-gate.sh --mode full

Expected behavior:

• Full scanner pass before release workflow can continue.
• Artifacts retained for audit and incident response.

3) Nightly (continuous)

Nightly workflow should run:

scripts/security-gate.sh --mode full

Expected behavior:

• Detects drift/regressions outside active PR windows.
• Failing run creates actionable signal in workflow summary/issues.

Triage Guidance

When gate fails:

1. Open latest artifact in .agents/security/ and identify scanner + file.
2. Classify severity (critical/high/medium).
3. Fix immediately for critical/high or create tracked follow-up issue with owner.
4. Re-run scripts/security-gate.sh until gate passes.

Reporting Template

Security gate run: <run-id>
Mode: <quick|full>
Result: <pass|blocked>
Top findings:
- <scanner> <severity> <file> <summary>
Actions:
- <fix or issue id>

Notes

• Use this as the canonical security runbook instead of ad-hoc scanner commands.
• Keep workflow wiring aligned with this contract in:
  • .github/workflows/validate.yml
  • .github/workflows/nightly.yml
  • .github/workflows/release.yml
