For people having trouble with Opus “wandering off” or refusing to read full blocks of code before coming to their own conclusions this might help you. First of all update your Claude.md file to instruct Opus to “under no circumstances are you to ever make an assumption about or implement a design without reading and understanding the entire code structure”. Second - Fable is an excellent code reviewer and taskmaster while also being extremely capable at implementing whatever you throw at it. This makes it an even better orchestrator for Opus, who is extremely detail-oriented and loves to second-guess itself (in a good way, less bugs ultimately wind up implemented because it’s constantly checking and re-checking). Rely on Fable to dole out the work and to keep Opus’ bad habits in check. It’s been working wonders. Try this prompt: “For this session I would like you, Fable, to be the orchestrator, reviewer, and final approval for all implementation work. Please dispatch the new Opus 5 model to be your implementer. All work done by Opus will be undergo an adversarial review by you, Fable, before final approval.” submitted by /u/Brocsta876
