Application security hub: built-in /security-review plus lanes for OWASP Top 10, secrets, dependency CVEs, prompt-injection defense, CodeQL CI, variant analysis and incident response. Use when asked to audit security, scan for secrets or vulnerable packages, harden an AI app, or handle a breach.

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

# $ccc-security — Find, prove, fix vulnerabilities

**CC Commander** · $ccc-security · a verified security findings report for the current repository, routed to the right specialist lane.

This skill extends Claude Code's built-in `/security-review`; it does not reimplement it. Lane commands and checklists live in [references/lanes.md](references/lanes.md). The user's selected model is preserved; the only tier routing here is the optional `fable` threat-model delegation in step 4.

## When to use / when not to

Use for: a security audit or OWASP check, secrets or credential scanning, dependency CVE and license audits, hardening an LLM-powered feature against prompt injection, wiring CodeQL into CI, hunting variants of a known bug, or running an active incident.

Not for: infrastructure and SaaS-account hardening before launch (use `$ccc-harden`), general code-quality review (use `$ccc-code-review`), or destructive-command guardrails for the session (use `$ccc-safety`).

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-security@sha256:a38c273b8b854e16

The line at the top of this page pins the label git:20261013.fbe187d, 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.
