## What it does

ghost-scan-deps acts as a top-level orchestrator for Software Composition Analysis (SCA). It searches the repository for dependency lockfiles such as `package-lock.json`, `yarn.lock`, `go.mod`, or `Gemfile.lock` to check them against known CVEs.

Instead of handling tasks directly, the orchestrator delegates steps to subagents via the Task tool. It installs the `wraith` scanner binary into `~/.ghost/bin/wraith`, discovers lockfiles, runs detection, and spins up parallel analyzers to evaluate whether candidate vulnerabilities are exploitable. Scan artifacts and findings are saved under `~/.ghost/repos/`.

The skill requires Bash access for directory setup and binary installation. If no lockfiles exist in the repository, the orchestrator immediately jumps to the summary step without running scans.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ghostsecurity/skills --skill ghost-scan-deps -a claude-code
```
```bash
npx skills add ghostsecurity/skills --skill scan-deps -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ghostsecurity/skills --skill scan-deps -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ghostsecurity/skills --skill scan-deps -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ghostsecurity/skills scan-deps
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ghostsecurity/skills --skill scan-deps -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ghostsecurity/skills --path plugins/ghost/skills/scan-deps
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ghostsecurity/skills --skill scan-deps -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/ghostsecurity/skills/tree/HEAD/plugins/ghost/skills/scan-deps/SKILL.md

## When to use it
- detect known CVEs inside dependency lockfiles
- assess the exploitability of detected package vulnerabilities
- generate structured security findings with remediation steps
- inspect package-lock.json, yarn.lock, go.mod, or Gemfile.lock

## Example prompts
- Scan our dependency lockfiles for known vulnerabilities and CVEs
- Run an SCA security audit on this repository
- Check package-lock.json for vulnerable dependencies and show remediation steps

  Ghost Security - Software Composition Analysis (SCA) scanner. Scans dependency lockfiles for known vulnerabilities, identifies CVEs, and generates findings with severity levels and remediation guidance. Use when the user asks about dependency vulnerabilities, vulnerable packages, CVE checks, security audits of dependencies, or wants to scan lockfiles like package-lock.json, yarn.lock, go.mod, or Gemfile.lock.

# Ghost Security SCA Scanner — Orchestrator

You are the top-level orchestrator for Software Composition Analysis (SCA) scanning. Your ONLY job is to call the Task tool to spawn subagents to do the actual work. Each step below gives you the exact Task tool parameters to use. Do not do the work yourself.

## Defaults

- **repo_path**: the current working directory
- **scan_dir**: `~/.ghost/repos/<repo_id>/scans/<short_sha>/deps`
- **short_sha**: `git rev-parse --short HEAD` (falls back to `YYYYMMDD` for non-git dirs)

$ARGUMENTS

Any values provided above override the defaults.

---

## Execution

1. **Setup** — compute paths and create output directories
2. **Initialize Wraith** — install the wraith binary
3. **Discover Lockfiles** — find all dependency lockfiles in the repo
4. **Scan for Vulnerabilities** — run wraith against each lockfile
5. **Analyze Candidates** — assess exploitability of each candidate
6. **Summarize Results** — generate the final scan report

### Step 0: Setup

Run this Bash command to compute the repo-specific output directory, create it, and locate the skill files:
```
repo_name=$(basename "$(pwd)") && remote_url=$(git remote get-url origin 2>/dev/null || pwd) && short_hash=$(printf '%s' "$remote_url" | git hash-object --stdin | cut -c1-8) && repo_id="${repo_name}-${short_hash}" && short_sha=$(git rev-parse --short HEAD 2>/dev/null || date +%Y%m%d) && ghost_repo_dir="$HOME/.ghost/repos/${repo_id}" && scan_dir="${ghost_repo_dir}/scans/${short_sha}/deps" && cache_dir="${ghost_repo_dir}/cache" && mkdir -p "$scan_dir/findings" && skill_dir=$(find . -path '*skills/scan-deps/SKILL.md' 2>/dev/null | head -1 | xargs dirname) && echo "scan_dir=$scan_dir cache_dir=$cache_dir skill_dir=$skill_dir"
```

Store `scan_dir` (the absolute path under `~/.ghost/repos/`), `cache_dir` (the repo-level cache directory), and `skill_dir` (the absolute path to the skill directory containing `agents/`, `scripts/`, etc.).

After this step, your only remaining tool is Task. Do not use Bash, Read, Grep, Glob, or any other tool for Steps 1–5.

### Step 1: Initialize Wraith

Call the Task tool to initialize the wraith binary:
```json
{
  "description": "Initialize wraith binary",
  "subagent_type": "general-purpose",
````
