Self-taught dev moves assistant from n8n to LangGraph — asks what to change
A self-taught developer migrated a local-first voice and chat assistant from n8n workflows to a LangGraph Python service, with MCP tool servers for Gmail, Calendar and Spotify plus approval prompts before risky actions. The thread asks for design feedback on the migration, and the useful answers focus on keeping the verifier cheap and splitting tools into read vs. write with different approval levels.
