How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition โ†’

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:

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.

Quick Start (3 Steps)

Step 1: Initialize baselines

cd ~/.openclaw/workspace
python3 skills/soul-guardian/scripts/soul_guardian.py init --actor setup --note "initial baseline"

Step 2: Enable monitoring

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:

## Soul Guardian Check
- Run `python3 skills/soul-guardian/scripts/soul_guardian.py check --actor heartbeat --output-format alert`
- If any output is produced, relay it to the user immediately as a security alert

That's it! Soul Guardian will now:

  • โœ… Detect unauthorized changes to protected files
  • โœ… Auto-restore SOUL.md and AGENTS.md to approved baseline
  • โœ… Alert you when drift is detected and handled

What it protects (default policy)

| File | Mode | Action on drift | |------|------|-----------------| | SOUL.md | restore | Auto-restore + alert | | AGENTS.md | restore | Auto-restore + alert | | USER.md | alert | Alert only | | TOOLS.md | alert | Alert only | | IDENTITY.md | alert | Alert only | | HEARTBEAT.md | alert | Alert only | | MEMORY.md | alert | Alert only | | memory/*.md | ignore | Ignored |

Commands

Check for drift (with alert output)

python3 skills/soul-guardian/scripts/soul_guardian.py check --output-format alert
  • Silent if no drift
  • Outputs human-readable alert if drift detected
  • Perfect for heartbeat integration

Watch mode (continuous monitoring)

python3 skills/soul-guardian/scripts/soul_guardian.py watch --interval 30

Runs continuously, checking every 30 seconds.

Approve intentional changes

python3 skills/soul-guardian/scripts/soul_guardian.py approve --file SOUL.md --actor user --note "intentional update"

View status

python3 skills/soul-guardian/scripts/soul_guardian.py status

Verify audit log integrity

python3 skills/soul-guardian/scripts/soul_guardian.py verify-audit

---

Alert Format

When drift is detected, the `--output-format alert` produces output like:
