ai-agent-security skillA
ai-agent-security is agent-read markdown (skill) from sickn33/agentic-awesome-skills: Secure AI agents against prompt injection, tool abuse, and data exfiltration.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# AI Agent Security Protect agentic AI systems from adversarial input, unsafe tool execution, data leakage, and privilege abuse with layered security controls. ## Prerequisites - Python 3.10+ for guardrail code examples - Docker or Podman for sandbox execution - OpenTelemetry collector for audit logging - Familiarity with your agent framework (LangChain, CrewAI, Autogen, custom) - Access to policy engine (OPA/Cedar) for permission boundaries ## Threat Model — STRIDE for AI Agents AI agents introduce a unique threat surface. Apply STRIDE specifically to agentic components: | Threat | Agent-Specific Example | Control | |--------|----------------------|---------| | **Spoofing** | Attacker crafts input that mimics a trusted internal tool response | Signed tool responses, HMAC verification | | **Tampering** | Prompt injection modifies agent reasoning mid-chain | Input validation, prompt armoring | | **Repudiation** | Agent takes destructive action with no audit trail | Immutable structured logging | | **Information Disclosure** | Agent leaks PII, secrets, or internal architecture in responses | Output filtering, content classifiers | …

How to install
mdr add sickn33/agentic-awesome-skills/ai-agent-security@v2.0mdr add sickn33/agentic-awesome-skills/ai-agent-security@sha256:66776bd8ae1842abPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
