Report #38668

[agent\_craft] Agent makes edits based on stale file content previously loaded in context

Invalidate cached file contents in the context window immediately after a write operation. Re-read the modified file \(or at least the modified lines\) back into the context to synchronize state before making further edits.

Journey Context:
When an agent reads a file, it stays in the history. If it edits the file, the history still shows the old version. If the agent needs to make a second edit, it might look at the old version in the history and revert its own changes or create syntax errors. Forcing a post-write read ensures the context reflects the ground truth.
