GuavaGuard 🛡️ — Part of the guard-scanner Ecosystem
Runtime security scanner and monitor for your OpenClaw agent.
🔗 Looking for full static scanning? →
clawhub install guard-scanner(150+ patterns, 23 categories, 4,000+ downloads)
GuavaGuard watches tool calls in real-time and warns when it detects dangerous patterns — reverse shells, credential exfiltration, sandbox escapes, and more.
Quick Start
# 1. Install the full security scanner suite
clawhub install guard-scanner # Static scanner (150+ patterns)
clawhub install guava-guard # Runtime monitor (12 patterns)
# 2. Pre-install safety gate
npx guard-scanner ./skills --self-exclude --verbose
# 3. Enable the runtime hook
openclaw hooks install skills/guava-guard/hooks/guava-guard
openclaw hooks enable guava-guard
# 4. Restart gateway, then verify:
openclaw hooks list # Should show 🍈 guava-guard as ✓ ready
