I had my first go at using it (Github Copilot) last week, for a simple refactoring task. I'd have to say I reasonably specified it, yet it still managed to to fail to delete a closing brace when it removed the opening block as specified.

That was using the Claude Sonnet 4.5 model, I wonder if using the Opus 4.5 model would have managed to avoid that.
