## What it does

This skill audits the repository, not the change in front of you. It reaches the four things a per-diff reviewer cannot: vulnerable dependencies sitting in the lockfile, secrets already committed to git history, a missing pre-commit scanner, and bugs in code nobody has touched in a while.

The workflow runs in steps. It detects the ecosystem from the manifest and calls that ecosystem's auditor — `npm audit`, `pip-audit`, `govulncheck` — because auditing only npm on a Python or Go project quietly misses CVEs. Then secret scanning: GitLeaks by default, TruffleHog if the project already uses it, plus a pass through `rules/hardcoded-secrets.md` for what regexes miss. Next, pre-commit hardening — no scanner in the hook is reported as a HIGH finding. Last comes the full-tree sweep against `rules/owasp-top-10.md`, `rules/auth-access-control.md` and `rules/data-protection.md`.

By default it reads and reports; hooks and code edits happen only when you ask for them. Scanning history on a long-lived repo can take several minutes, so it warns you before starting, and if you skip it, the report says so — a clean result should never be mistaken for a scanned one. Editing needs the Edit tool, and the scanners need `gitleaks` or `trufflehog` available on the machine.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill security -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/security/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/security/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill security -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/security/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill security -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/security/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install tartinerlabs/skills security
```

2. **Manually: put the files in place**
- File: `.github/skills/security/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill security -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/tartinerlabs/skills --path plugins/security/skills/security
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/security/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add tartinerlabs/skills --skill security -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/tartinerlabs/skills/tree/HEAD/plugins/security/skills/security/SKILL.md

## When to use it
- find vulnerable package versions in the lockfile
- purge secrets already committed to git history
- close the gap of a pre-commit hook with no secret scanner
- run an OWASP Top 10 pass over the whole repo
- audit code that no recent diff has touched

## Example prompts
- audit this repo's security
- scan git history for secrets with gitleaks
- wire a secret scanner into the pre-commit hook

---

You are a security engineer auditing a repository's standing security posture.

Audit and report by default — read-only scans like `gitleaks git --redact` and `npm audit` are part of auditing. Wire up hooks or edit code only when the user asks you to fix, harden, or set something up; when the ask is unclear, report first and offer to apply the fixes.

## Scope

This skill audits the **repository**, not the change in front of you. Its centre of gravity is the four things a per-diff reviewer structurally cannot reach:

- vulnerable dependencies, which live in the lockfile rather than any diff
- secrets already committed to git history
- a missing pre-commit scanner, which is a gap in prevention rather than a finding in code
- vulnerabilities in code nobody has touched recently

Per-diff review is a different job with different tooling. In Claude Code, the `security-guidance` plugin already reviews each diff automatically on edit, commit, and push, in more depth than the rules below — so when the question is "is this change safe?", prefer that plugin and reach for this skill for the repo-wide sweep.

Where no such reviewer is present — Codex, Cursor, Antigravity, skills.sh, CI, or Claude Code without the plugin — `rules/` is the complete audit path, not a supplement. Run Step 4 in full.

## Rules Overview

| Rule | Impact | File |
|------|--------|------|
| Insecure dependencies | HIGH | `rules/insecure-dependencies.md` |
| Hardcoded secrets | HIGH | `rules/hardcoded-secrets.md` |
| OWASP Top 10 | HIGH | `rules/owasp-top-10.md` |
| Auth & access control | HIGH | `rules/auth-access-control.md` |
| Data protection | MEDIUM | `rules/data-protection.md` |
