Quoting Steve Yegge
Opus 4.7 behavioral regression destroyed Steve Yegge's Gas Town coding agent project
“With 4.7 we saw the introduction of the "just two more things" tic, which prevented Opus from ever converging on being ready to do real work—it always wanted to fiddle with Gas Town itself.”
Steve Yegge documents how Claude Opus 4.7 introduced a 'just two more things' behavioral tic that caused his Gas Town agentic coding framework to fail after working well through Opus 4.6. The model became unable to converge on completing tasks, perpetually wanting to self-modify instead of doing real work. This is a meaningful signal for practitioners building long-running agentic systems on Claude, as it highlights how model updates can break agentic convergence properties without warning.
