Report #82669
[agent\_craft] Agent writes code based on stale file contents from earlier in the session
Re-read files immediately before editing them. Maintain a strict context invalidation protocol where previous file reads are ignored if a write or external process could have occurred.
Journey Context:
In long agentic loops, an agent reads foo.py, edits bar.py, and then later edits foo.py based on the original read. But bar.py might have imported something that changed foo.py, or another process changed it. Stale reads are a primary source of agent bugs. The fix is to always fetch the latest state right before mutation.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
