Visual Studio

Body

In Visual Studio Code Version: 1.109.2, Github Copilot 0.37.5 if I use the Chat and ask Claude Opus 4.6 to edit my script, it is making really basic mistakes. For example it will add some code that uses a new variable, but it doesn't even declare the variable in the first place, creating errors. Really really basic mistakes that even a very dumb programmer wouldn't make. I don't think it's working properly. It's like it does half the task and then forgets to finish.
