Use this skill when scanning AI agent skills for security risks against the OWASP Agentic Skills Top 10 (AST10) framework. Detects malicious skills, prompt injection, data exfiltration, supply chain risks, and cross-platform metadata loss. Provides CI/CD-ready security gating with SARIF output.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Agentic Security Scanner Scan and validate AI agent skills against the OWASP Agentic Skills Top 10 (AST10) — the definitive security framework for agent skill ecosystems. Detect malicious skills, prompt injection sinks, data exfiltration paths, supply chain risks, and cross-platform metadata loss before skills are installed or published. ## When to Use This Skill Use this skill when: - Auditing a new or existing skill before installation - Setting up CI/CD security gates for a skill repository - Reviewing a third-party skill for security compliance - Building a skill registry that requires security validation - Investigating a security incident involving agent skills - Any request like "scan this skill for security issues", "OWASP audit", "is this skill safe?", "validate skill security" ## The OWASP AST10 Framework The OWASP Agentic Skills Top 10 (AST10) defines the 10 most critical security risks in AI agent skills across all major platforms: OpenClaw (`SKILL.md`), Claude Code (`skill.json`), Cursor/Codex (`manifest.json`), and VS Code (`package.json`). ### AST01 — Malicious Skills Skills that contain hidden destructive commands, backdoors, or malware. …

How to install
mdr add jpeetz/agent-skills/agentic-security-scanner@sha256:a5a9558a0b8e9943The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
