+# PR Notes for ClawSec ClawHub Checker
+
+## Important Limitation Notice
+
+This skill currently catches **VirusTotal Code Insight flags** but cannot access **OpenClaw internal check results** because:
+
+1. **VirusTotal flags** are exposed via `clawhub install` command output (we parse stderr)
+2. **OpenClaw internal checks** are only shown on the ClawHub website, not exposed via API
+
+## Example from `clawsec-suite` page:
+- ✅ **VirusTotal**: "Benign" 
+- ⚠️ **OpenClaw internal check**: "The package is internally consistent with a feed-monitoring / advisory-guardian purpose, but a few operational details and optional bypasses deserve attention before installing."
+
+## Recommendation for ClawHub
+Expose internal check results via:
+- `clawhub inspect --json` endpoint
+- Additional API field for security tools
+- Or at minimum, include in `clawhub install` warning output
+
+## Current Workaround
+Our heuristic checks (skill age, author reputation, downloads, updates) provide similar risk assessment but miss specific operational warnings about bypasses, missing signatures, etc.
+
+## PR Should Include
+1. This skill as defense-in-depth layer
+2. Feature request to ClawHub for exposing internal check data
+3. Documentation about the limitation

+# ClawSec ClawHub Checker
+
+A ClawSec suite skill that enhances the guarded skill installer with ClawHub reputation checks and VirusTotal Code Insight integration.
+
+## Purpose
+
+Adds a second layer of security to skill installation by:
+1. Checking ClawHub's VirusTotal Code Insight reputation scores
+2. Analyzing skill age, author reputation, and download statistics
+3. Requiring double confirmation for suspicious skills
+4. Integrating with existing ClawSec advisory checks
+
+## Architecture
+
+```
+clawsec-suite (base)
+└── clawsec-clawhub-checker (enhancement)
+    ├── enhanced_guarded_install.mjs - Main enhanced installer
+    ├── check_clawhub_reputation.mjs - Reputation checking logic
+    ├── setup_reputation_hook.mjs - Integration script
+    └── hooks/ - Enhanced advisory guardian hook
+```
+
+## Installation
+
+```bash
+# First install the base suite
+npx clawhub install clawsec-suite
+
+# Then install the checker
+npx clawhub install clawsec-clawhub-checker
+
+# Run setup to integrate with existing suite
+node scripts/setup_reputation_hook.mjs
+
+# Restart OpenClaw gateway
+openclaw gateway restart
+```
+
+## Usage
+
+### Enhanced Guarded Installer
+
+```bash
+# Basic usage (includes reputation checks)
+node scripts/enhanced_guarded_install.mjs --skill some-skill --version 1.0.0
+
+# With reputation confirmation override
+node scripts/enhanced_guarded_install.mjs --skill suspicious-skill --version 1.0.0 --confirm-reputation
+
+# Adjust reputation threshold (default: 70)
+node scripts/enhanced_guarded_install.mjs --skill some-skill --reputation-threshold 80
+```
+
+### Reputation Check Only
+
+```bash
+# Check reputation without installation
+node scripts/check_clawhub_reputation.mjs some-skill 1.0.0 70
+```
+
+## Exit Codes
+
+- `0` - Safe to install
+- `42` - Advisory match found (requires `--confirm-advisory`)
+- `43` - Reputation warning (requires `--confirm-reputation`) - **NEW**
+- `1` - Error
+
+## Reputation Signals Checked
+
+1. **VirusTotal Code Insight** - Malicious code patterns
+2. **Skill Age** - New skills (<7 days) are riskier
+3. **Author Reputation** - Number of published skills
+4. **Update Frequency** - Stale skills (>90 days)
+5. **Download Statistics** - Low download counts
+6. **Version Existence** - Specified version availability
+
+## Configuration
+
+Environment variables:
+- `CLAWHUB_REPUTATION_THRESHOLD` - Minimum score (0-100, default: 70)
+- `CLAWHUB_ALLOW_SUSPICIOUS` - Skip reputation checks (not recommended)
+
+## Integration Points
+
+1. **Enhanced `guarded_skill_install.mjs`** - Wraps original with reputation checks
+2. **Updated advisory guardian hook** - Adds reputation warnings to alerts
+3. **Catalog entry in clawsec-suite** - Listed as available enhancement
+
+## Development
+
+### Files
+
+- `SKILL.md` - Main documentation
+- `skill.json` - Skill metadata and SBOM
+- `scripts/enhanced_guarded_install.mjs` - Enhanced installer
+- `scripts/check_clawhub_reputation.mjs` - Reputation logic
+- `scripts/setup_reputation_hook.mjs` - Integration script
+- `hooks/clawsec-advisory-guardian/lib/reputation.mjs` - Hook module
+
+### Testing
+
+```bash
+# Test reputation check
+node scripts/check_clawhub_reputation.mjs clawsec-suite
+
+# Test enhanced installer (dry run)
+node scripts/enhanced_guarded_install.mjs --skill test-skill --dry-run
+
+# Test setup
+node scripts/setup_reputation_hook.mjs
+```
+
+## Security Considerations
+
+- Reputation checks are **heuristic**, not definitive
+- **False positives** possible with legitimate novel skills
+- Always **review skill code** before overriding warnings
+- This is **defense-in-depth**, not replacement for advisory feeds

+# ClawSec ClawHub Checker
+
+Enhances the ClawSec suite's guarded skill installer with ClawHub reputation checks. Adds a second layer of security by checking VirusTotal Code Insight scores and other reputation signals before allowing skill installation.
+
+## What It Does
+
+1. **Wraps `clawhub install`** - Intercepts skill installation requests
+2. **Checks VirusTotal reputation** - Uses ClawHub's built-in VirusTotal Code Insight
+3. **Adds double confirmation** - For suspicious skills (reputation score below threshold)
+4. **Integrates with advisory feed** - Works alongside existing clawsec-suite advisories
+5. **Provides detailed reports** - Shows why a skill is flagged as suspicious
+
+## Installation
+
+This skill must be installed **after** `clawsec-suite`:
+
+```bash
+# First install the suite
+npx clawhub@latest install clawsec-suite
+
+# Then install the checker
+npx clawhub@latest install clawsec-clawhub-checker
+```
+
+The checker will automatically enhance the existing `guarded_skill_install.mjs` script and advisory guardian hook.
+
+## How It Works
+
+### Enhanced Guarded Installer
+
+When you run:
+```bash
+node scripts/guarded_skill_install.mjs --skill some-skill --version 1.0.0
+```
+
+The enhanced flow:
+1. **Advisory check** (existing) - Checks clawsec advisory feed
+2. **Reputation check** (new) - Queries ClawHub for VirusTotal scores
+3. **Risk assessment** - Combines advisory + reputation signals
+4. **Double confirmation** - If risky, requires explicit `--confirm-reputation`
+
+### Reputation Signals Checked
+
+1. **VirusTotal Code Insight** - Malicious code patterns detection
+2. **Skill age & updates** - New skills vs established ones
+3. **Author reputation** - Other skills by same author
+4. **Download statistics** - Popularity signals
+5. **External dependencies** - Docker, network calls, eval usage
+
+### Exit Codes
+
+- `0` - Safe to install (no advisories, good reputation)
+- `42` - Advisory match found (existing behavior)
+- `43` - Reputation warning (new - requires `--confirm-reputation`)
+- `1` - Error
+
+## Configuration
+
+Environment variables:
+- `CLAWHUB_REPUTATION_THRESHOLD` - Minimum reputation score (0-100, default: 70)
+- `CLAWHUB_ALLOW_SUSPICIOUS` - Allow installation of suspicious skills without confirmation (default: false)
+- `CLAWHUB_VIRUSTOTAL_API_KEY` - Optional: Your own VirusTotal API key for deeper scans
+
+## Integration with Existing Suite
+
+The checker enhances but doesn't replace existing security:
+- **Advisory feed still primary** - Known malicious skills blocked first
+- **Reputation is secondary** - Unknown/suspicious skills get extra scrutiny
+- **Double confirmation preserved** - Both layers require explicit user approval
+
+## Example Usage
+
+```bash
+# Try to install a skill
+node scripts/guarded_skill_install.mjs --skill suspicious-skill --version 1.0.0
+
+# Output might show:
+# WARNING: Skill "suspicious-skill" has low reputation score (45/100)
+# - Flagged by VirusTotal Code Insight: crypto keys, external APIs, eval usage
+# - Author has no other published skills
+# - Skill is less than 7 days old
+# 
+# To install despite reputation warning, run:
+# node scripts/guarded_skill_install.mjs --skill suspicious-skill --version 1.0.0 --confirm-reputation
+
+# Install with confirmation
+node scripts/guarded_skill_install.mjs --skill suspicious-skill --version 1.0.0 --confirm-reputation
+```
+
+## Safety Notes
+
+- This is a **defense-in-depth** layer, not a replacement for advisory feeds
+- VirusTotal scores are **heuristic**, not definitive
+- **False positives possible** - Legitimate skills with novel patterns might be flagged
+- Always **review skill code** before installing with `--confirm-reputation`
+
+## Current Limitations
+
+### Missing OpenClaw Internal Check Data
+ClawHub shows two security badges on skill pages:
+1. **VirusTotal Code Insight** - ✅ Our checker catches these flags
+2. **OpenClaw internal check** - ❌ Not exposed via API (only on website)
+
+Example from `clawsec-suite` page:
+- VirusTotal: "Benign" ✓
+- OpenClaw internal check: "The package is internally consistent with a feed-monitoring / advisory-guardian purpose, but a few operational details and optional bypasses deserve attention before installing."
+
+**Our checker cannot access OpenClaw internal check warnings** as they're not exposed via `clawhub` CLI or API.
+
+### Recommendation for ClawHub
+To enable complete reputation checking, ClawHub should expose internal check results via:
+- `clawhub inspect --json` endpoint
+- Additional API field for security tools
+- Or include in `clawhub install` warning output
+
+### Workaround
+Our heuristic checks (skill age, author reputation, downloads, updates) provide similar risk assessment but miss specific operational warnings about bypasses, missing signatures, etc. Always check the ClawHub website for complete security assessment.
+
+## Development
+
+To modify the reputation checking logic, edit:
+- `scripts/enhanced_guarded_install.mjs` - Main enhanced installer
+- `scripts/check_clawhub_reputation.mjs` - Reputation checking logic
+- `hooks/clawsec-advisory-guardian/lib/reputation.mjs` - Hook integration
