Report #92170

[agent\_craft] Agent makes edits to a file but then reasons based on the old version of the file still in its context

After a file-editing tool is executed, immediately re-read the modified file \(or the modified section\) into the context to overwrite the stale state, or implement a state-tracking mechanism that invalidates cached file contexts upon mutation.

Journey Context:
LLMs treat context as immutable truth. If an agent reads a file, edits it, and then tries to write another edit based on the original read, it will often produce incorrect diffs or overwrite its own changes. This is a classic stale-state bug. Re-reading the file post-edit guarantees the agent's context matches the actual filesystem state, preventing cascading edit failures.
