name: openclaw-skill-scanner description: Security gate for OpenClaw AgentSkills. Scans folder/ClawHub skills with cisco-ai-defense/skill-scanner before installation. Supports manual scans, staged installs, and auto-quarantine of high-risk skills via systemd. binaries: - uv - npx - git - systemctl env: - OPENCLAW_STATE_DIR - OPENCLAW_WORKSPACE_DIR

Skill Scanner Guard

Harden OpenClaw’s skill supply chain: - Scan skills with cisco-ai-defense/skill-scanner - Block only on High/Critical - Allow Medium/Low/Info but warn - Auto-scan on changes to ~/.openclaw/skills - Quarantine failing skills to ~/.openclaw/skills-quarantine

Quick start

Install skill-scanner (repo + uv env)

cd "$HOME/.openclaw/workspace"
# or wherever you keep repos

git clone https://github.com/cisco-ai-defense/skill-scanner
cd skill-scanner
CC=gcc uv sync --all-extras

Note: some environments try gcc-12 while building yara-python; forcing CC=gcc avoids that.

Workflows

1) Scan all user skills (manual)

User skills live at: - ~/.openclaw/skills

Run:

$HOME/.openclaw/skills/skill-scanner-guard/scripts/scan_openclaw_skills.sh

Outputs go to: - /home/rev/.openclaw/workspace/skill_scans/

2) Install a folder skill with scan gate (copy/clone workflow)

Use the wrapper instead of copying directly:

$HOME/.openclaw/skills/skill-scanner-guard/scripts/scan_and_add_skill.sh /path/to/skill-dir

Policy: - Block only if High/Critical exist (unless --force) - Still installs if only Medium/Low/Info exist, but prints a warning summary

3) Install from ClawHub with scan gate (staging install)

Install to a staging dir, scan, then copy into ~/.openclaw/skills only if allowed:

$HOME/.openclaw/skills/skill-scanner-guard/scripts/clawhub_scan_install.sh <slug>
# optionally
$HOME/.openclaw/skills/skill-scanner-guard/scripts/clawhub_scan_install.sh <slug> --version <version>

4) Auto-scan + quarantine on change (systemd user units)

Install the units (templates are in references/):

mkdir -p ~/.config/systemd/user
cp -a "$HOME/.openclaw/skills/skill-scanner-guard/references/openclaw-skill-scan."* ~/.config/systemd/user/

systemctl --user daemon-reload
systemctl --user enable --now openclaw-skill-scan.path

Behavior: - Any change under ~/.openclaw/skills/ triggers scripts/auto_scan_user_skills.sh - If High/Critical findings exist, the script moves failing skill directories to: ~/.openclaw/skills-quarantine/<skillname>-<timestamp> - Reports are written to: /home/rev/.openclaw/workspace/skill_scans/auto/

Inspect:

systemctl --user status openclaw-skill-scan.path
journalctl --user -u openclaw-skill-scan.service -n 100 --no-pager
ls -la ~/.openclaw/skills-quarantine

这是一个质量不错且非常实用的 OpenClaw 安全工具。它能在安装 skills 前自动扫描风险，对高危问题进行阻断或隔离，保护系统安全。文档完善、流程清晰、使用简单。稍有不佳的是脚本里有些硬编码路径可能在不同环境下出问题，以及依赖外部扫描工具。不过整体而言，这是一个值得信赖的安全加固工具。
