Report #83543

[agent\_craft] Agent writes a file but later acts as if the file is still in its original state because the context window is dominated by the pre-write state

After a mutating tool execution \(write, delete, move\), immediately re-read the affected file or directory to refresh the context window with the ground truth.

Journey Context:
Agents often read a file, decide on an edit, write the edit, and then move on. But the context window still contains the original file content from the read step. If the agent needs to make a second edit, it will base it on the stale pre-edit version, leading to overwrites or conflicts. While returning the diff helps, the safest pattern is to force a re-read of the mutated artifact to synchronize the agent's context with the filesystem reality.
