ccc-security

ccc-security is a skill for Claude Code from KevinZai/commander. It costs 36 tokens per session (1,004 once invoked), scanned A, original, MIT.

A security review hub that starts Claude Code’s built-in security review and routes you to specialist checks for application security.

In plain words
What is it for?
It helps audit code, dependencies, secrets, OWASP Top 10 risks, prompt-injection defenses, CodeQL setup, repeated vulnerability patterns, and incident response.
Why use it?
It gathers several security tasks in one entry point, so you do not need to know which review to start with.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ccc-security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

$ccc-security — Security domain hub

Load ONE skill. Get the entire application security domain. 8 skills in one.

Integration note: This skill invokes Claude Code's built-in /security-review command as the entry point, then routes to specialist sub-skills for deeper analysis. It does not reimplement the security review — it extends it.

Sub-Skills

# Skill Focus
1 security-audit Comprehensive security audit — SAST, DAST, manual review
2 prompt-injection-defense Defend AI-powered apps against prompt injection attacks
3 dependency-audit Audit npm/pip/cargo dependencies for known vulnerabilities
4 secrets-scanner Scan codebase for hardcoded secrets, API keys, tokens
5 owasp-top-10 Check application against OWASP Top 10 vulnerabilities
6 codeql-integration Set up CodeQL for automated security analysis in CI
7 variant-analysis Find variants of known vulnerabilities across codebase
8 incident-response Security incident response playbook and remediation

No expressed intent? Present the top 3 sub-skills + "More…" as an AskUserQuestion picker (≤4 options).

Routing Matrix

Your Intent Route To
"Security audit" / "Review for vulnerabilities" /security-reviewsecurity-audit + owasp-top-10
"Prompt injection" / "AI app security" prompt-injection-defense
"Vulnerable dependencies" / "npm audit" dependency-audit
"Hardcoded secrets" / "API key scan" secrets-scanner
"OWASP" / "Top 10 check" owasp-top-10
"CodeQL" / "Automated security CI" codeql-integration
"Find all variants of this bug" variant-analysis
"Security incident" / "We were breached" incident-response

Protocol

  1. Always start with /security-review built-in — it provides the initial scan surface
  2. Route to specialist skills for deeper analysis per domain
  3. secrets-scanner and dependency-audit on every new project
  4. owasp-top-10 before every production release
  5. incident-response for active security events — stop all other work first

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ccc-security is a skill published in the GitHub repository KevinZai/commander (6 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 1,004 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
