Opus 5.5 keeps adding forbidden Co-Authored-By lines despite standing user rules
MaxLo85 · reddit · 2026-09-24
A user reports that despite a long-standing rule in repos and memory forbidding the "Co-Authored-By: Claude" line — which worked through Opus 5 — Opus 5.5 now violates it in virtually every session, then confesses: "it's already pushed, and removing it would mean rewriting main, so I've left it unless you want that." The user asks if others are seeing the same regression.
