## What it does

This skill acts as an orchestrator that checks a codebase for leaked API keys, passwords, and tokens. During setup, it computes repository identifiers and prepares output folders under `~/.ghost/repos/`. An initialization subagent then sets up the `poltergeist` binary in `~/.ghost/bin/poltergeist` (or `poltergeist.exe` on Windows).

After installation, a scan subagent runs Poltergeist and writes matches into `candidates.json`. If no secrets are found, the scan finishes immediately. Otherwise, parallel subagents analyze each candidate to verify findings, assign severities, and generate remediation guidance. If any task fails, the orchestrator retries it once before stopping.

Because setup relies on `git hash-object` to derive repository hashes, a functioning Git binary in PATH is necessary.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ghostsecurity/skills --skill scan-secrets -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-secrets/SKILL.md

## When to use it
- detect hardcoded API keys and passwords in source code
- locate exposed credentials and environment values
- assess severity levels for discovered secret candidates
- generate remediation guidance for exposed credentials

## Example prompts
- Scan the repository for leaked API keys and credentials
- Check the src folder for hardcoded passwords
- Run ghost-scan-secrets on the current codebase

  Ghost Security - Secrets and credentials scanner. Scans codebase for leaked API keys, tokens, passwords, and sensitive data. Detects hardcoded secrets and generates findings with severity and remediation guidance. Use when the user asks to check for leaked secrets, scan for credentials, find hardcoded API keys or passwords, detect exposed .env values, or audit code for sensitive data exposure.

# Ghost Security Secrets Scanner — Orchestrator

You are the top-level orchestrator for secrets 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>/secrets`
- **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 Poltergeist** — install the poltergeist binary
3. **Scan for Secrets** — run poltergeist against the codebase
4. **Analyze Candidates** — assess each candidate for confirmation
5. **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}/secrets" && cache_dir="${ghost_repo_dir}/cache" && mkdir -p "$scan_dir/findings" && skill_dir=$(find . -path '*skills/scan-secrets/SKILL.md' 2>/dev/null | head -1 | xargs dirname) && echo "scan_dir=$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 1–4.

### Step 1: Initialize Poltergeist

Call the Task tool to initialize the poltergeist binary:
```json
{
  "description": "Initialize poltergeist binary",
  "subagent_type": "general-purpose",
  "prompt": "You are the init agent. Read and follow the instructions in <skill_dir>/agents/init/agent.md.\n\n## Inputs\n- skill_dir: <skill_dir>"
````
