Description
Scan ClawHub skills for security vulnerabilities BEFORE installing. Use when installing new skills from ClawHub to detect prompt injections, malware payloads, hardcoded secrets, and other threats. Wraps clawhub install with mcp-scan pre-flight checks.
Usage Guidance
Install only if you are comfortable reviewing and running a shell script that stages, scans, deletes, moves, and installs skill directories. Avoid --skip-scan and --force unless you fully intend those effects, use only normal ClawHub slugs, and prefer verified package-manager installation for dependencies like uv.
Capability Analysis
Type: OpenClaw Skill Name: skill-guard Version: 1.0.2 This skill, 'skill-guard', is designed to enhance security by scanning other OpenClaw skills for vulnerabilities before installation. The `SKILL.md` documentation clearly outlines its purpose and methods, without any prompt injection attempts. The `scripts/safe-install.sh` script uses legitimate tools (`clawhub`, `uvx`, `mcp-scan`) to download skills to a temporary staging area (`/tmp`), scan them, and only install them if no security issues are detected. It does not exhibit any malicious behaviors such as data exfiltration, unauthorized remote control, or persistence mechanisms. While the installation instructions for its `uv` dependency suggest `curl | sh`, this is a common method for that specific tool and is an instruction for the user, not an action performed by the skill's core logic for a malicious payload.
Capability Assessment
Purpose & Capability
The purpose is coherent: it stages ClawHub skills, scans them with mcp-scan, and installs only after a clean result in the default path.
Instruction Scope
The script includes a user-selectable --skip-scan path that installs without scanning, while the top-level documentation strongly presents the tool as a pre-install security gate.
Install Mechanism
It relies on external CLIs and documents a curl-to-shell uv installer; that is disclosed dependency guidance, but users should verify the installer source.
Credentials
The script performs rm -rf operations using the supplied skill slug without validating it as a simple slug or checking path boundaries, creating avoidable local deletion risk if a malformed slug is used.
Persistence & Privilege
Installing or overwriting skills under the OpenClaw workspace is expected for the tool, but --force can replace existing skill content and should be treated as destructive.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install skill-guard
  3. After installation, invoke the skill by name or use /skill-guard
  4. Provide required inputs per the skill's parameter spec and get structured output
