tl;dr you have to rewrite all your stack to get the performance you want out of Opus 5 but then it rocks. I see all the posts of people complaining about how bad Opus 5 is. And it is true, the verbosity (which then eats context, which causes drift) is tough. But when you edit your agent definitions, skills, and change the process to suit Opus 5 (and see the https://platform.claude.com/docs/en/build-with-claude/prompt-engineering/prompting-claude-opus-5)… . It starts to work quite well. They’ve also trained it so it doesn’t make as many “bad” unrecoverable decisions, but it does seem like they’ve lowered the temperature as well. It pairs really well for work with a fable planner…. submitted by /u/OldFartNewDay
