Here's what it did with my Why are some of my extensions or keybindings' when clauses broken in VS Code 1.77's official and insiders releases? :
It changed the meaning by removing the word "when" and "commands" in "when certain contributed commands [...]". And it stripped out the markdown links (even though your prompt clearly tells it to maintain them).
When given my How do set(var ${var} value) and set(var "${var}" value) work in CMake?, it just nuked everything and replaced it with "How does the behavior of the variable "foo" differ when it is set without and with quotes in CMake?", which is just a completely different question. Thanks I guess :/
When given my Why isn't the remaining visible code of a folded block in VS Code highlighted for me?, it nuked the markdown links again, and made a bunch of wording choice changes that I'd reject in the edit-suggestion review queue as making no improvement.
