Report #9201

[agent\_craft] Agent generates a large code patch, but the context window has drifted from the actual file state, causing the patch to fail application

Always re-read the specific lines of the target file immediately before generating a patch or edit. Do not rely on the file's state as it exists earlier in the context window.

Journey Context:
In multi-turn edits, an agent might read a file, make an edit, then make another edit based on the original read. If the first edit changed lines, the second edit's line numbers or context might mismatch the new state. Re-reading the file right before the edit ensures the diff applies cleanly against the current state, avoiding merge conflicts and failed tool calls.
