I don't know what they have done to Claude, but when using through copilot it's truly awful compared to using it straight from the API.

I have always just used the API, but I decided to give copilot a go on the weekend because of the cheap price. And I am seeing weird behavior like I have never seen before... It will somehow fail to use the file editing tool and then spend an absolutely huge amount of time/tokens building a python script to apply the edit in a sub process... And it will spin it's wheels on stuff the API routinely just gets right in one shot.

This might have been bad timing. Copilot API broke things last weekend with caused a lot of tool calls in various agent harnesses to start failing like the edit tool.
