Summary

  • Add UserMemory model and user_memories table for storing per-user facts/preferences
  • Add save_user_memory LangChain agent tool so users can say "remember that..." and the agent persists it
  • Inject saved memories into the system prompt on every conversation turn for automatic recall
  • Exact-match dedup prevents duplicate memories

Test plan

  • Send "Remember that my favorite color is blue" — verify tool_start/tool_end SSE events for save_user_memory
  • Start a new conversation, ask "What's my favorite color?" — agent answers from memory
  • Verify SELECT * FROM user_memories shows the saved fact
  • Confirm duplicate messages refresh updated_at instead of creating a new row

Add user memory feature for cross-conversation recall c95800e65d 
Give the LangChain agent a save_user_memory tool so users can ask it to
remember preferences and personal facts. Memories are stored per-user in
a new user_memories table and injected into the system prompt on each
conversation turn.
