# security-guidance Security review for Claude-generated code. Three layers: 1. **Pattern warnings** — instant regex-based reminders on `Edit`/`Write` for ~25 known-dangerous patterns (`yaml.load`, `torch.load(weights_only=False)`, `pickle.load` on untrusted data, raw `innerHTML`, hardcoded secrets, etc.). 2. **LLM diff review** — when Claude finishes a turn, the plugin sends the diff to a fast LLM call (Opus 4.7 by default) and feeds high-severity findings back to Claude so it can fix them be
