How this skill gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

AI/ML Security
When to Activate
- Red-teaming an LLM/chatbot/copilot for direct & indirect prompt injection and multi-turn jailbreaks.
- Testing a RAG pipeline for document/embedding poisoning, embedding inversion, and cross-tenant retrieval leakage.
- Auditing an AI agent / MCP server for tool poisoning, excessive agency, and command injection (RCE).
- Scanning a model artifact (HuggingFace, `.pt/.pkl/.bin/.gguf`) for deserialization payloads before loading it.
- Assessing a model API for extraction/distillation, membership inference, and adversarial-suffix robustness.
- Mapping findings to OWASP LLM Top-10 (2025) + MITRE ATLAS for a report.
