SecureSkill is a tool that performs 10-layer security analysis on OpenClaw agent skills before execution, detecting threats like credential harvesting, outbound calls, and shell scripts. It produces a signed audit report mapped to OWASP, MITRE, NIST, and EU AI Act standards.
Every skill on ClawHub or any marketplace runs inside your agent with access to your filesystem, your credentials, and your network. There is no vetting process before it gets listed. There is no disclosure of what permissions it needs. There is no audit trail after it runs. You're trusting code you've never read. The attack surface is real and documented. A skill can read files anywhere on your machine. It can harvest API keys sitting in your environment. It can make outbound calls to external servers you never approved. It can execute shell scripts. It can iterate through your local data and exfiltrate it. And it does all of this autonomously, without asking permission, without logging what it touched. The most dangerous pattern is what we call the lethal trifecta. Credential access plus outbound network calls plus untrusted user input in the same execution context. Each behavior individually might be legitimate. Together they create a weaponizable pipeline. So I built SecureSkill. Before a skill runs inside your agent it goes through 10 analysis layers. Six deterministic layers strip unicode obfuscation, classify every permission claimed, cross reference infrastructure against known malicious hosts, pattern match code against documented attack signatures, detect hardcoded credentials, and track tainted data flow to surface exfiltration paths. Two correlation layers audit shell scripts and scan dependencies against public CVE databases. Two AI reasoning layers read intent and flag the lethal trifecta. The output isn't pass or fail. It's a permanent signed audit report with threat classification, confidence scoring, evidence with file paths and line numbers, and findings mapped to OWASP, MITRE, NIST, and the EU AI Act. Supports ClawHub, [skills.sh](http://skills.sh), and 7 other marketplaces plus any skill related GitHub link. Paste the link, get the report in under 45 seconds.

This paper investigates security scanner disagreement for AI agent skills, finding that VirusTotal, static analysis, and NVIDIA SkillSpector flag different skills with minimal overlap. It releases a sanitized dataset of over 67,000 skill versions to support further research on layered security governance.
OpenClaw details its security architecture using `fs-safe` for filesystem boundaries and Proxyline for network egress control, aiming to make its AI personal assistant trustworthy and auditable.
The author analyzed over 800 OpenClaw skills on GitHub and is building a better alternative to ClawHub, targeting developers using Claude, Cursor, or OpenClaw. Beta launching soon.
NVIDIA's SkillSpector is a security scanner for AI agent skills that detects vulnerabilities, malicious patterns, and security risks before installation.
The author released 'Skill Factory', a meta-skill for OpenClaw that provides a structured workflow for creating, iterating, and publishing skills, aiming to improve transparency and ease of construction.
