Report #15832

[agent\_craft] Agent hallucinates code or overwrites recent changes because it is relying on a stale version of a file stored earlier in its context window

Always re-read a file immediately before editing it, or use an editing tool that applies diffs/patches rather than rewriting the whole file from memory. Never trust the file state in the conversation history.

Journey Context:
In a multi-turn conversation, an agent might read main.py, do other things, then edit main.py. If another tool \(or human\) modified main.py in the interim, the agent's context holds a stale version. Rewriting from the stale version reverts changes. Re-reading ensures the context matches the filesystem state, or applying search-and-replace diffs avoids full-file rewrites.
