Mine would be: "Show me everywhere this API is used incorrectly across the entire codebase", current tools can find syntax errors but can't identify logical misuse.
Curious what capabilities would transform your workflow if technical limitations weren't a factor.
I know there's often this weird mentality that WYSIWYG editors are for noobs, but I don't mind. They have their place. I love visual UI work. Dreamweaver was helpful for its time. Figma is great but doesn't produce functional components.

This is possible these days with (you guessed it) LLMS, likely with RAG. In fact I've made MCPunk https://github.com/jurasofish/mcpunk with exactly this in mind. There's a nack to wielding it effectively (bullying the LLM just right, feeling when it's bullshitting, etc) but it feels like this kind of capability will soon be commoditised. Super handy for code review like "Hey pal are the changes in the currently checked out branch logically consistent with the rest of the codebase"
