Openclaw Signet Pro

OpenClaw Signet Pro

Everything in openclaw-signet (free) plus automated countermeasures.

Free version alerts. Pro version subverts, quarantines, and defends.

Detection Commands (also in free)

Sign Skills

Generate SHA-256 content hashes for all installed skills and store in trust manifest.

python3 {baseDir}/scripts/signet.py sign --workspace /path/to/workspace

Sign Single Skill

python3 {baseDir}/scripts/signet.py sign openclaw-warden --workspace /path/to/workspace

Verify Skills

Compare current skill state against trusted signatures. Reports exactly which files were modified, added, or removed.

python3 {baseDir}/scripts/signet.py verify --workspace /path/to/workspace

Verify Single Skill

python3 {baseDir}/scripts/signet.py verify openclaw-warden --workspace /path/to/workspace

List Signed Skills

Display the trust manifest with hashes, file counts, and quarantined skills.

python3 {baseDir}/scripts/signet.py list --workspace /path/to/workspace

Quick Status

One-line health check: verified, tampered, unsigned, quarantined counts.

python3 {baseDir}/scripts/signet.py status --workspace /path/to/workspace

Pro Countermeasures

Reject Unsigned Skills

Remove unsigned skills from the workspace. Moves them to .quarantine/signet/ with metadata recording why they were rejected.

# Reject all unsigned skills
python3 {baseDir}/scripts/signet.py reject --workspace /path/to/workspace

# Reject a specific unsigned skill
python3 {baseDir}/scripts/signet.py reject untrusted-skill --workspace /path/to/workspace

Quarantine a Tampered Skill

Disable a skill by renaming its directory with a .quarantined- prefix so the agent will not load it. Records tampering evidence (expected vs actual hashes, changed files) in .quarantine/signet/{skill}-evidence.json.

python3 {baseDir}/scripts/signet.py quarantine bad-skill --workspace /path/to/workspace

Unquarantine a Skill

Restore a quarantined skill to its original name. Warns that it should be re-signed before trusting.

python3 {baseDir}/scripts/signet.py unquarantine bad-skill --workspace /path/to/workspace

Snapshot a Verified Skill

Create a trusted backup of a signed skill. Only succeeds if the skill currently passes verification (hash matches manifest). Snapshots are stored in .signet/snapshots/{skill}/.

python3 {baseDir}/scripts/signet.py snapshot openclaw-warden --workspace /path/to/workspace

Restore from Snapshot

Restore a skill from its trusted snapshot. Verifies snapshot integrity before restoring. Updates the trust manifest to match the restored state.

python3 {baseDir}/scripts/signet.py restore openclaw-warden --workspace /path/to/workspace

Protect (Automated Sweep)

Full automated protection sweep. Recommended for session startup.

1. Verify all skills against the trust manifest
2. Auto-quarantine tampered skills (with evidence)
3. Optionally reject unsigned skills (--reject-unsigned flag, off by default)
4. Create/update snapshots of all verified skills

# Standard protection (quarantine tampered, snapshot clean)
python3 {baseDir}/scripts/signet.py protect --workspace /path/to/workspace

# Strict protection (also reject unsigned skills)
python3 {baseDir}/scripts/signet.py protect --reject-unsigned --workspace /path/to/workspace

Recommended Integration

Session Startup Hook (Claude Code)

{
  "hooks": {
    "SessionStart": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "python3 scripts/signet.py protect",
            "timeout": 30
          }
        ]
      }
    ]
  }
}

Heartbeat (OpenClaw)

Add to HEARTBEAT.md for periodic protection:

- Run skill signature protection (python3 {skill:openclaw-signet-pro}/scripts/signet.py protect)
