what task did you stop doing yourself once this clicked

For months I treated it like a search engine, typing little questions and getting little answers back. The change for me was handing over an entire messy task, messy files included, and just describing what done looks like. The first time it came back with something I would have actually shipped, I sat there staring at the screen for a minute.

Now I catch myself before starting anything repetitive and ask whether its worth writing out as a proper handoff instead. Curious what the moment was like for everyone else. Was there a specific task where you realised you would never go back to the old way?
