Security Skill

Purpose: Run repeatable security checks across code, scripts, authorized binaries, and repo-managed prompt surfaces.

Use this skill for a caller-requested repository scan, authorized binary assurance, dependency risk, secrets, or offline prompt-surface redteam.

Critical Constraints

• Scan only repositories, binaries, and prompt surfaces the operator owns or is explicitly authorized to assess. Why: a security review does not grant access to third-party systems or proprietary material.
• Keep collection read-only by default; do not exfiltrate secrets, execute destructive payloads, or mutate policy/baselines to manufacture green. Why: the assessment must not become the incident or erase its evidence.
• Treat missing/error scanners as a coverage gap, never a clean finding; use --require-tools when complete tool coverage is required. Why: absent evidence is not evidence of absence.
• Use the current agent and local shell; do not start another runtime or orchestration substrate unless explicitly requested. Why: repository scanning is a bounded operation, not permission to fan out.
• Run the selected scan once and report findings plus coverage gaps. Remediation, risk acceptance, reruns, and promotion are caller decisions.

Security Surfaces

1. Repository gate: scripts/security-gate.sh composes available scanners for quick/full/release checks.
2. Composable suite: scripts/security_suite.py provides static, dynamic, contract, baseline, and policy primitives for authorized binaries.
3. Offline redteam: scripts/prompt_redteam.py checks repo-owned prompt and tool-control surfaces against the attack pack.
