Install in OpenClaw
/install skill-guard
Description
Stage, scan, and install a ClawHub skill when the user requests a guarded ClawHub installation. Blocks installation on security findings or incomplete scans.
Usage Guidance
Install only if you are comfortable letting this helper download the requested skill, upload its staged text content to Snyk for analysis, and modify your OpenClaw workspace after a clean scan. Use trusted clawhub and uvx binaries, provide SNYK_TOKEN through a secret manager or environment, and review retained .skill-guard quarantine or backup directories if a scan or replacement fails.
Capability Assessment
Credentials
The required SNYK_TOKEN, clawhub/uvx tools, network access, and workspace file writes are proportionate to guarded installation, but users should understand that staged skill content is sent to Snyk's service for analysis.
Install Mechanism
The shell entrypoint only delegates to the Python helper, which validates slug and version inputs, uses argument-list subprocess calls, downloads through the ClawHub CLI, scans before promotion, and blocks malformed or incomplete results.
Instruction Scope
Runtime instructions are clear about staging, scanning, blocking findings, not executing downloaded skill content, and retaining quarantined files; the manifest does not add a separate machine-readable permission scope.
Persistence & Privilege
The helper creates a private .skill-guard state area, lock file, retained staging directories, and previous-skill backups; this persistence is disclosed and recovery-oriented, not a background service or hidden hook.
Purpose & Capability
The skill has high-impact authority to install or replace a ClawHub skill, but that authority is the stated purpose and is limited to a validated single slug with explicit --force for replacement.
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
Version History
v1.0.3
Harden guarded installs: validate inputs, remove scan bypasses, use private staging, require complete scanner results, and retain backups with rollback. Pin Snyk Agent Scan 0.6.3 and fix its parent-directory result handling. Adds regression and real-tool verification scripts. Requires Python 3.9+ and SNYK_TOKEN; authenticated cloud end-to-end verification remains pending.
v1.0.2
Added competitive comparison table. Emphasizes what skill-guard catches that VirusTotal and skillscanner miss: prompt injections, data exfiltration, hidden instructions, AI-specific threats.
v1.0.1
Pre-install security scanning for ClawHub skills
v1.0.0
Initial release: pre-install security scanning for ClawHub skills. Scan before you install — detect prompt injections, malware, secrets, and data exfiltration. Powered by mcp-scan (Invariant/Snyk).
