I let Claude take the wheel with various non-professional projects which often means heavy subagent workflows. Prompts like this easily eat through my 5x Max plan limits:

> I want you to look for UI issues related to transitions. Look for jumps, reverts, or anything that doesn't follow UI/UX best practices. You might need to figure out how best to even record and review UI transitions. Do all testing locally on a local dev server, but make sure to undo any database changes you make in the process of testing. Be exhaustive and report back with an .html report that highlights the visual issues and proposed solutions so I can review each one. Ultracode on.

Which means I have up to 10 Opus 5.5 medium agents running concurrently for long stretches of time.

I want to be clear I don't think that using Claude in this way gets you the best possible results. But when the app is fully vibecoded then audit prompts like the one above can be seen as a definite net positive. Making Claude think really hard about various improvement routines will get you better results in that one aspect than Claude's first attempt to build something from scratch did.
