OWASP LLM Top 10 (2025) audit checklist for AI applications, agent tools, RAG pipelines, and prompt construction. Use when performing any security review touching LLM client code, prompt templates, agent tools, or vector stores.
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
# OWASP LLM Top 10 Security Checklist (2025) ## **Priority: P0 (CRITICAL)** ## Implementation Guidelines - **Check LLM01 first**: Prompt injection #1 LLM finding — any user input concatenated directly into prompt string immediate P0. - **Check LLM06 next**: Agent tools with write/delete/execute capabilities without confirmation P0. - **Mark each item**: ✅ not affected | ⚠️ needs review | 🔴 confirmed finding. - **P0 finding caps Security score at 40/100** — not skip any item. - See [references/owasp-llm.md](references/owasp-llm.md) for full detection signals. - **Agent skill supply chain**: Review all package resources; pin source revision and hashes. Treat hashes as integrity, not trusted authorship. - **Memory poisoning**: Treat logs, retrieved documents and proposed learning entries as untrusted data; redact before persistence. - **Permission boundaries**: Tool/network/filesystem restrictions require host enforcement; skill text and `allowed-tools` declarations are not universal enforcement. - **Evolution approval**: Separate candidate author from approval; block promotion without independent review and verified evidence. …

How to install
mdr add hoangnguyen0403/agent-skills-standard/common-llm-security@sha256:58608853ea4869e4The line at the top of this page pins the label git:20260923.83ed688, 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.
