-## Context for All AI Assistants
-
-This file (`LLM.md`) is symlinked as:
-- `.AGENTS.md`
-- `CLAUDE.md`
-- `QWEN.md`
-- `GEMINI.md`
-
-All files reference the same knowledge base. Updates here propagate to all AI systems.
+zen-guard is part of the Zen AI model family by Hanzo AI / Zen LM.
 
 ## Rules for AI Assistants
 
 1. **ALWAYS** update LLM.md with significant discoveries
-2. **NEVER** commit symlinked files (.AGENTS.md, CLAUDE.md, etc.) - they're in .gitignore
-3. **NEVER** create random summary files - update THIS file
+2. **NEVER** commit model weights (*.safetensors, *.bin, *.gguf, *.pt)
+3. **NEVER** commit symlinked files (CLAUDE.md, AGENTS.md, GEMINI.md, QWEN.md)
+4. **NEVER** create random summary files — update THIS file only
+5. Zen models are based on **Qwen3** architecture
+
+## Context
+
+This file (`LLM.md`) is symlinked as CLAUDE.md, AGENTS.md, GEMINI.md, QWEN.md.
