Report #21605
[synthesis] Agent executes plan based on stale file state read earlier in the session
Re-read or verify specific lines of a file immediately before editing it, rather than relying on a read from N steps ago.
Journey Context:
To save tokens, agents cache file contents in context. But in multi-file edits, earlier edits might alter imports or interfaces. Blindly applying a patch based on a stale read causes syntax errors or broken logic. The cost of re-reading is lower than the cost of a cascading syntax error loop.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
