[agent\_craft] Agent tries to maintain complex state — counters, data structures, intermediate results — purely within conversation text

Externalize all mutable state to code: write progress to JSON files, maintain variables in executed scripts, store intermediate results in temp files. The context window is for reasoning and instructions; code execution is your state store. Never trust the model to accurately track state across turns via conversation text alone.

Journey Context:
Agents frequently try to track state like 'files processed: \[a.py, b.py, c.py\]' or 'error count: 3' purely in conversation text. This is fragile for three reasons: \(1\) the model can miscount or lose track of list items across long conversations, \(2\) summarization destroys this state entirely, \(3\) there's no way to verify the state is correct — it's just text the model generated. The right pattern is to treat the workspace as the agent's external memory: write a \_progress.json file, maintain a running Python script with variables, or append to a log file. This is the 'code as state' pattern: the context window holds the reasoning about what to do next, and the filesystem holds the facts about what has been done. OpenHands \(formerly OpenDevin\) implements this by giving the agent a sandboxed runtime where the workspace IS the persistent memory. The tradeoff is that reading state back requires a tool call, but this is a feature, not a bug — it guarantees the state is fresh and verified.
