3 hacks
Connect the Claude in Chrome extension so Claude can open your app, click through flows, read console errors, and iterate until the UI actually works.
Double-Esc /rewind back to after useful file reads, then re-prompt with what you learned—without the failed approach still in context.
"Never add comments" in CLAUDE.md plus "make this readable" in your prompt is a contradiction Claude has to resolve before it writes a line. Find those pairs and pick one.
