security

security is a skill for Claude Code from rube-de/cc-skills. It costs 40 tokens per session (2,129 once invoked), scanned A, original, MIT.

A security-review workflow that checks software dependencies, source code, and stored credentials for common security problems.

In plain words
What is it for?
Use it to audit Node.js, Python, Rust, Go, Java, Kotlin, or Ruby projects, including each project inside a monorepo, and create a structured GitHub issue.
Why use it?
It brings together the security checks suited to the project's programming language and reports issues by severity.

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

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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DLC: Security Scan

Run security checks against the current project and create a GitHub issue with findings.

Before running, read ../dlc/references/ISSUE-TEMPLATE.md now for the issue format, and read ../dlc/references/REPORT-FORMAT.md now for the findings data structure.

Step 1: Detect Project Type

Scan the repository root for project indicators:

Indicator Project Type Primary Tool
package.json / package-lock.json / bun.lockb Node.js npm audit / bun audit
requirements.txt / pyproject.toml / Pipfile Python pip-audit
Cargo.toml Rust cargo audit
go.mod Go govulncheck
pom.xml / build.gradle Java/Kotlin dependency-check
Gemfile Ruby bundler-audit

If multiple indicators exist, treat as a monorepo and scan each.

Step 2: Run Security Tools

For each detected project type, run tools in this priority order. Use the first available tool; skip unavailable ones.

Dependency Audit

Select the tool based on availability (command -v), not exit codes — audit tools exit non-zero when vulnerabilities are found, which is a valid result to capture.

# Node.js — select by availability
if command -v npm >/dev/null 2>&1; then
  npm audit --json 2>/dev/null
elif command -v bun >/dev/null 2>&1; then
  bun audit 2>/dev/null
fi

# Python
command -v pip-audit >/dev/null 2>&1 && pip-audit --format=json 2>/dev/null

# Rust
command -v cargo-audit >/dev/null 2>&1 && cargo audit --json 2>/dev/null

# Go
command -v govulncheck >/dev/null 2>&1 && govulncheck ./... 2>/dev/null

Dependency Staleness

Check for packages significantly behind the latest stable release — these accumulate security patches without formal CVEs.

Select tools based on availability (command -v), not exit codes — staleness tools exit non-zero when outdated packages are found, which is a valid result to capture.

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.

security is a skill published in the GitHub repository rube-de/cc-skills (10 stars, last pushed 4d ago), licensed MIT. It adds 40 tokens to every session and 2,129 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
