# soul-guardian 👻

Protects your agent's core files (SOUL.md, AGENTS.md, etc.) from unauthorized changes with automatic detection, restoration, and **user alerting**.

## Vercel Skills Installation

Install with the Vercel Skills CLI for this harness:

```bash
npx skills add prompt-security/clawsec --skill soul-guardian -a openclaw -y
```

## Operational Notes

- Required runtime: `python3`
- Optional runtime: `openclaw` for cron integration, `launchctl` for macOS scheduling, `bash` for the demo helper
- Side effects: can auto-restore protected files to their approved baseline and writes audit/quarantine state locally
- Network behavior: none by default
- Trust model: any scheduling is opt-in, but restore mode intentionally overwrites drifted files

## Release Artifact Verification

For standalone installs, verify the signed release manifest before trusting `SKILL.md`, `skill.json`, or the archive. The `skill.json` file is the package metadata/SBOM source, and the release pipeline signs `checksums.json` with the ClawSec release key.

```bash
set -euo pipefail

Only install or extract the archive after this verification succeeds.

## Quick Start (3 Steps)

### Step 1: Initialize baselines
```bash
cd ~/.openclaw/workspace
python3 skills/soul-guardian/scripts/soul_guardian.py init --actor setup --note "initial baseline"
```

### Step 2: Enable monitoring
```bash
python3 skills/soul-guardian/scripts/soul_guardian.py enable-monitoring
```
This shows you how to add monitoring to your workflow.

### Step 3: Add to HEARTBEAT.md (Recommended)

Add this to your HEARTBEAT.md for automatic monitoring:
