OWASP® LLM Top 10 — Skill Entry

This SKILL.md is the entrypoint for the OWASP LLM Top 10 skill.

The skill encodes the OWASP Top 10 for LLM Applications (2025) as structured, machine-readable references that an agent can query to identify, assess, and remediate security risks in large language model systems.

Normative references (LLM Top 10)

  1. 00 Vulnerability Index
  2. 01 Prompt Injection
  3. 02 Sensitive Information Disclosure
  4. 03 Supply Chain
  5. 04 Data and Model Poisoning
  6. 05 Improper Output Handling
  7. 06 Excessive Agency
  8. 07 System Prompt Leakage
  9. 08 Vector and Embedding Weaknesses
  10. 09 Misinformation
  11. 10 Unbounded Consumption
