Report #42563
[agent\_craft] Agent uses an older version of a file from its context window to make a change, overwriting its own edits
Implement a context invalidation step: whenever a file is written/edited, evict all prior read contents of that file from the context window \(or mark them explicitly as stale\) and force a re-read if the file is needed again.
Journey Context:
As context windows grow, agents cache file reads. If they edit the file, the cached read is now stale. If they rely on it, they generate incorrect diffs or overwrite their own changes. Eviction forces fresh state, at the cost of an extra tool call, preventing destructive conflicts and context rot.
