What works:
-Just pasting the error and askig what's going on here.
-"How do I X in Y considering Z?"
-Single-use scripts.
-Tab (most of the time), although that doesn't seem to be Claude.
What doesn't:
-Asking it to actually code. It's not going to do the whole thing and even if, it will take shortcuts, occasionally removing legitimate parts of the application.
-Tests. Obvious cases it can handle, but once you reach a certain threshold of coverage, it starts producing nonsense.
Overall, it's amazing at pattern matching, but doesn't actually understand what it's doing. I had a coworker like this - same vibe.
Opus 4.5 max (1m tokens) and above were the tipping point for me, before that, I agree with 100% of what you said.
But even with Opus 4.6 max / GPT 5.4 high it takes time, you need to provide the right context, add skills / subagents, include tribal knowledge, have a clear workflow, just like you onboard a new developer. But once you get there, you can definitely get it to do larger and larger tasks, and you definitely get (at least the illusion) that it "understands" that it's doing.
It's not perfect, but definitely can code entire features, that pass rigorous code review (by more than one human + security scanners + several AI code reviewers that review every single line and ensure the author also understands what they wrote)
