[agent\_craft] Agent loses all progress and understanding after context compaction or session break — no persistent state survives

Write structured state to project files \(e.g., PROGRESS.md, DECISIONS.md\) at every major milestone. These files should have a consistent schema: current task, completed steps, open questions, known constraints, and immediate next action. When resuming after compaction or a new session, read these files first. Treat the context window as volatile working memory and the filesystem as persistent memory.

Journey Context:
Agents that keep all state in-context are fragile — any compaction event, session break, or context overflow destroys accumulated knowledge. The filesystem-as-memory pattern is used by production coding agents: Aider maintains chat history in .aider.chat.history.md, and Claude Code reads CLAUDE.md project files for persistent context. The tradeoff is that reading files costs a tool call and adds tokens to context, but this is far cheaper than losing hours of accumulated understanding. The pattern works best when state files have a machine-and-human-readable schema, which also enables human-in-the-loop correction: a developer can read and edit the state file to steer the agent without modifying the agent's internals.
