+# AI Assistant Knowledge Base
+
+**Last Updated**: $(date +%Y-%m-%d)
+**Project**: $(basename "$REPO_PATH")
+**Organization**: $(basename "$(dirname "$REPO_PATH")")
+
+## Project Overview
+
+This repository is part of the $(basename "$(dirname "$REPO_PATH")") organization.
+
+## Essential Commands
+
+### Development
+```bash
+# Add common commands here
+```
+
+## Architecture
+
+## Key Technologies
+
+## Development Workflow
+
+## 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.
+
+## 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
+
+---
+
+**Note**: This file serves as the single source of truth for all AI assistants working on this project.
