Last time we covered context compaction — solving “how much the current session can remember”. But a coding assistant needs another kind of memory: long-term memory across sessions.

You close Claude Code and reopen it tomorrow. What should it know?

  • You prefer TypeScript over JavaScript
  • You said last time “don’t use the underscore library”
  • This project uses Vitest, not Jest
  • You once corrected one of its misunderstandings

Context compaction can’t handle these. The session ends, the history clears, tomorrow is a fresh window. If the AI needs you to re-explain everything each time, it isn’t an assistant — it’s a burden.
