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 outputExecution Contract
1) Pre-PR (fast)
Run quick gate:
scripts/security-gate.sh --mode quickExpected behavior:
- Fails on high/critical findings from available scanners.
- Writes artifacts under
$TMPDIR/agentops-security/<run-id>/.
2) Pre-Release (strict)
Run full gate:
scripts/security-gate.sh --mode fullExpected 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 fullExpected behavior:
- Detects drift/regressions outside active PR windows.
- Failing run creates actionable signal in workflow summary/issues.
Triage Guidance
When gate fails:
- Open latest artifact in
$TMPDIR/agentops-security/and identify scanner + file. - Classify severity (critical/high/medium).
- Fix immediately for critical/high or create tracked follow-up issue with owner.
- Re-run
scripts/security-gate.shuntil 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
- For binary/internal black-box assurance plus offline repo-surface redteam, use:
- skills/security-suite/SKILL.md (includes security_suite.py and prompt_redteam.py)
- For dependency vulnerability and license scanning, use:
- deps — Dependency audit, vulnerability scanning, and license compliance
Examples
Scenario: Quick Security Gate Before Opening a PR
User says: /security
What happens:
- The skill runs
scripts/security-gate.sh --mode quick, which executes available scanners (semgrep, gosec, gitleaks) against the current working tree and flags high/critical findings. - Run
/deps vulnto scan for vulnerable dependencies (OWASP A06: Vulnerable and Outdated Components). - Scan artifacts are written to
$TMPDIR/agentops-security/<run-id>/for review, and the gate reports a pass/blocked verdict.
Result: The gate passes with no high/critical findings, confirming the branch is safe to open a PR.
Scenario: Full Security Gate for a Release
User says: /security --release
What happens:
- The skill runs
scripts/security-gate.sh --mode full, which performs a comprehensive scan including all scanner passes, test-inclusive toolchain checks, and stricter severity thresholds. - Artifacts are retained under
$TMPDIR/agentops-security/<run-id>/for audit trail and incident response, and a structured report is generated.
Result: The full gate blocks the release on two medium-severity findings in cli/internal/config.go; the operator triages and fixes them before re-running the gate to get a clean pass.
Troubleshooting
| Problem | Cause | Solution |
|---|---|---|
| Gate reports "scanner not found" and skips checks | Required scanner (semgrep, gosec, or gitleaks) is not installed | Install the missing scanner: brew install semgrep, go install github.com/securego/gosec/v2/cmd/gosec@latest, or brew install gitleaks. |
| Gate passes locally but fails in CI | CI environment has additional scanners or stricter config | Compare $TMPDIR/agentops-security/ artifacts from both environments; align scanner versions and config files across local and CI. |
| False positive blocking the gate | Scanner flags a non-issue as high/critical severity | Add a scanner-specific inline suppression comment (e.g., # nosemgrep: rule-id) or update the scanner config to exclude the pattern, then document the suppression reason. |
Artifacts directory $TMPDIR/agentops-security/ not created | Script lacks write permissions or $TMPDIR is not writable | Verify $TMPDIR is set and writable; the script auto-creates subdirectories on each run. |
| Nightly scan not detecting regressions | Nightly workflow is not configured or is pointing at stale branch | Verify .github/workflows/nightly.yml runs scripts/security-gate.sh --mode full against the correct branch (typically main). |
