+# Claude Code Instructions
+
+**MANDATORY: Read AGENTS.md instead of this file.**
+
+This project uses a unified configuration file for all LLM coding agents.
+
+## Instructions
+
+1. **Read and follow AGENTS.md** - All project guidelines are located there
+2. **Do not modify this file** - Only update AGENTS.md
+3. **Do not create or modify other agent-specific files** - Use AGENTS.md as the single source of truth
+
+This approach ensures consistent behavior across all LLM coding agents without managing separate configuration files.
+
+---
+
+If you need to update project guidelines, edit AGENTS.md, not this file.
