The OWASP Agentic Skills Top 10 (AST10) is the first comprehensive security framework for AI agent skills. It documents the 10 most critical security risks in agentic AI skills across all major AI agent platforms, providing evidence-based mitigations and prevention strategies.
The OWASP Agentic Skills Top 10 (AST10) documents the 10 most critical security risks in agentic AI skills across all major AI agent platforms. Skills represent the execution layer that gives agents real-world impact: they define not just what resources agents can access, but how they orchestrate multi-step workflows autonomously.
While significant attention has been devoted to securing large language models (LLMs) and the Model Context Protocol (MCP) tool layer, the intermediate behavior layer—embodied in agentic skills—has emerged as a particularly vulnerable and under-protected component of the AI agent ecosystem. This project exists to close that gap.
Mental Model: MCP = how the model talks to tools; AST10 = what those tools actually do.
MAESTRO Mapping: Each AST10 risk is mapped to the Cloud Security Alliance's MAESTRO 7-layer threat model for agentic AI systems, enabling targeted threat localization and cross-layer risk analysis.
