Report #82885

[agent\_craft] Agent relies on conversational history to track mutable state, leading to stale variable references

Maintain a structured, explicitly updated 'scratchpad' or state object at the top of the context. On every state change \(e.g., file created, dependency installed\), rewrite the entire scratchpad, not just append the change.

Journey Context:
When an agent creates a file app.py and later renames it to server.py, the conversational history contains both events. If the agent relies on reading the history, it might reference the old app.py. By maintaining a single source-of-truth state block that is overwritten on mutation, the agent always sees the current reality. The tradeoff is slightly higher token usage per turn to rewrite the state, but it eliminates state synchronization bugs.
