A minimal open-source framework called Agent Kernel uses just three markdown files (memory.md, context.md, instructions.md) to give any AI agent persistent state, context accumulation, and behavioral rules without requiring a database or vector store. The approach is gaining traction on HN (24 points, 9 comments) as a zero-dependency pattern for adding statefulness to Claude Code, Cursor, and similar tools. Builder-relevant as a lightweight alternative to full memory frameworks like MemGPT.
