Install in OpenClaw
/install skill-guard
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 letting this skill run shell commands that stage, scan, and install other skills. Review safe-install.sh first, avoid --force unless you intend to replace an existing skill, and install uv through a trusted package manager or verified installer when possible.
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 stated purpose is to stage, scan, and then install other skills; using shell commands, temporary staging, external scan tools, and the OpenClaw skills directory is coherent with that purpose.
Instruction Scope
The documented install-anyway and force-overwrite paths affect installed skills, but they appear user-directed rather than hidden or automatic.
Install Mechanism
The skill depends on external CLIs and documents a curl-to-shell uv installer; the reported sourcing of $HOME/.local/bin/env is a hardening concern but not evidence of exfiltration or deception.
Credentials
The described file operations are scoped to /tmp/skill-guard-staging and the OpenClaw skills workspace, with no artifact-backed evidence of broad local indexing, credential harvesting, or unrelated network transfer.
Persistence & Privilege
Installing or overwriting a skill creates normal OpenClaw skill persistence, but no cron, background worker, privilege escalation, or system-level persistence was shown.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install skill-guard - After installation, invoke the skill by name or use
/skill-guard - Provide required inputs per the skill's parameter spec and get structured output
