Analysis
This article brilliantly demystifies the context window limitations of Claude Code, offering developers a highly practical guide to maintaining AI memory across sessions. By mapping out exactly where and how to store instructions, it transforms a frustrating context loss into a seamless, automated workflow. It is an incredibly empowering read for anyone looking to build complex, multi-session projects with AI Agents.
Key Takeaways
- •Claude Code starts with a fresh Context Window every session, meaning past conversations are not automatically saved.
- •When the context reaches 95% capacity, an automatic 'compaction' runs, which erases session-specific verbal instructions.
- •Information must be actively placed in designated areas like CLAUDE.md, auto memory, or file outputs to survive across sessions.
