Of course there is an upper limit for AI. There's an upper limit for humans too. What you need is just boring project management. Have a proper spec, architecture and tasks split into manageable chunks with enough information to implement them. Then you just start watching TV and say "implement github issue #42" to Claude and it'll get on with it. But if you say "build me facebook" and expect a shippable product, you'll have a bad time.
