I've gone from asking the tools how to do things, and cut and pasting the bits (often small) that'd be helpful, via using assistants that I'd review every decision of and often having to start over, to now often starting an assistant with broad permissions and just reviewing the diff later, after they've made the changes pass the test suite, run a linter and fixed all the issues it brought up, and written a draft commit message.

The jump has been massive.
