Report #46775
[synthesis] Agent confidently introduces semantic bugs by forcing premature abstractions across multiple files
Instruct the agent to make localized, inline edits first and delay refactoring into shared abstractions until all functional changes are verified by a full test suite run.
Journey Context:
RLHF trains models to prefer DRY, clean code. When modifying multiple files, the agent eagerly extracts shared logic. However, without runtime feedback, subtle differences in business logic are erased. The agent sees a syntactically correct abstraction \(partial success\) which masks the total failure of broken runtime semantics. Delaying refactoring separates the 'make it work' phase from the 'make it clean' phase.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
