kbarbel640-del OpenClaw Sentinel Pro
Everything in openclaw-sentinel (free) plus automated countermeasures.
Free version detects threats. Pro version subverts, quarantines, and defends.
Detection Commands (also in free)
Scan Installed Skills
Deep scan of all installed skills for supply chain risks. Checks file hashes against a local threat database, detects obfuscated code patterns, suspicious install behaviors, dependency confusion, and metadata inconsistencies. Generates a risk score (0-100) per skill.
python3 {baseDir}/scripts/sentinel.py scan --workspace /path/to/workspace
Scan a Single Skill
python3 {baseDir}/scripts/sentinel.py scan openclaw-warden --workspace /path/to/workspace
Pre-Install Inspection
Scan a skill directory BEFORE copying it to your workspace. Outputs a SAFE/REVIEW/REJECT recommendation and shows exactly what binaries, network calls, and file operations the skill will perform.
python3 {baseDir}/scripts/sentinel.py inspect /path/to/skill-directory
Manage Threat Database
View current threat database statistics.
python3 {baseDir}/scripts/sentinel.py threats --workspace /path/to/workspace
Import a community-shared threat list.
python3 {baseDir}/scripts/sentinel.py threats --update-from threats.json --workspace /path/to/workspace
Quick Status
Summary of installed skills, quarantined skills, scan history, SBOM history, and risk score overview.
python3 {baseDir}/scripts/sentinel.py status --workspace /path/to/workspace
Pro Countermeasures
Quarantine a Skill
Disable a risky skill by renaming its directory with a .quarantined- prefix. The agent will not load quarantined skills. Records full evidence (findings, file inventory, hashes) in .quarantine/sentinel/{skill}-evidence.json.
python3 {baseDir}/scripts/sentinel.py quarantine bad-skill --workspace /path/to/workspace
Unquarantine a Skill
Restore a quarantined skill after investigation. Shows the original quarantine evidence before restoring.
python3 {baseDir}/scripts/sentinel.py unquarantine bad-skill --workspace /path/to/workspace
Reject a Skill
Permanently remove a skill with HIGH+ risk score (50+). The skill is moved to .quarantine/sentinel/ for forensic review, not deleted. Skills below the threshold are blocked from rejection — use quarantine instead.
python3 {baseDir}/scripts/sentinel.py reject bad-skill --workspace /path/to/workspace
Generate SBOM
Generate a Software Bill of Materials for all installed skills. Includes file inventory with SHA-256 hashes, declared dependencies, detected dependencies, and risk scores. Saved to .sentinel/sbom-{timestamp}.json.
python3 {baseDir}/scripts/sentinel.py sbom --workspace /path/to/workspace
Continuous Monitoring
Compare the current scan against the previous scan. Reports new threats, changed risk scores, new skills, and removed/quarantined skills. Saves scan results to .sentinel/scans/ for historical tracking.
python3 {baseDir}/scripts/sentinel.py monitor --workspace /path/to/workspace
Protect (Automated Sweep)
Full automated protection sweep in one command: scan all skills, auto-quarantine CRITICAL risk skills (score 75+), generate SBOM, update scan history, and produce a protection report. This is the recommended command for session startup.
python3 {baseDir}/scripts/sentinel.py protect --workspace /path/to/workspace
Recommended Integration
Session Startup Hook (Claude Code)
{
"hooks": {
"SessionStart": [
{
"hooks": [
{
"type": "command",
"command": "python3 scripts/sentinel.py protect",
"timeout": 30
}
]
}
]
}
}
Heartbeat (OpenClaw)
Add to HEARTBEAT.md for periodic protection:
- Run supply chain protection sweep (python3 {skill:openclaw-sentinel-pro}/scripts/sentinel.py protect)
After Installing New Skills
Run protect to auto-quarantine skills that contain malicious patterns.
Workspace Auto-Detection
If --workspace is omitted, the script tries:
OPENCLAW_WORKSPACEenvironment variable- Current directory (if AGENTS.md exists)
~/.openclaw/workspace(default)
What It Detects
| Category | Patterns |
|---|---|
| Encoded Execution | eval(base64.b64decode(...)), exec(compile(...)), eval/exec with encoded strings |
| Dynamic Imports | __import__('os').system(...), dynamic subprocess/ctypes imports |
| Shell Injection | subprocess.Popen with shell=True + string concatenation, os.system() |
| Remote Code Exec | urllib/requests combined with exec/eval — download-and-run patterns |
| Obfuscation | Lines >1000 chars, high-entropy strings, minified code blocks |
| Install Behaviors | Post-install hooks, auto-exec in __init__.py, cross-skill file writes |
| Hidden Files | Non-standard dotfiles and hidden directories |
| Dependency Confusion | Skills shadowing popular package names, typosquatting near-matches |
| Metadata Mismatch | Undeclared binaries, undeclared env vars, invocable flag inconsistencies |
| Serialization | pickle.loads, marshal.loads — arbitrary code execution via deserialization |
| Known-Bad Hashes | File SHA-256 matches against local threat database |
Risk Scoring
Each skill receives a score from 0-100:
| Score | Label | Meaning |
|---|---|---|
| 0 | CLEAN | No issues detected |
| 1-19 | LOW | Minor findings, likely benign |
| 20-49 | MODERATE | Review recommended |
| 50-74 | HIGH | Significant risk, review required |
| 75-100 | CRITICAL | Serious supply chain risk — auto-quarantined by protect |
