 # Navi — Project Context for Claude
 
+## Working rules
+
+- **No unapproved steps.** Before implementing a change, propose the approach and wait for user confirmation. Do not make architectural decisions, add dependencies, or modify external interfaces without explicit approval.
+- **Check external libraries first.** When a task involves a third-party library (e.g. `gnexus-auth-client-py`), read the library source/docs before assuming behavior or inventing functionality.
+
 ## What this is
 Personal modular AI agent system. FastAPI backend + vanilla JS client. The agent is named Navi — female, loyal, uncensored personal assistant. Runs locally via Ollama.
