Report #1387

[agent\_craft] Agent edits a file, but later relies on its memory of the original file content, causing it to re-introduce deleted bugs or overwrite its own changes

Never rely on conversational history for the current state of a file. Always re-read the file \(or the specific modified function\) immediately before generating an edit or patch.

Journey Context:
LLMs treat context as a linear narrative. If an agent reads main.py, then modifies it, the context contains both the original read and the diff/patch. When asked to make another change, the LLM might attend to the original \(unmodified\) text in the context window rather than the post-edit state, leading to 'undoing' its own work. Re-reading forces the ground truth into the recency window.
