Q CLI has so many issues though, injects so much junk into you shell profiles it can slow down your terminal invocations by seconds, and it doesn't support standard streamableHttp / SSE MCP servers.
just turn those off, it's just 2 includes one at the top and one at the bottom of your shell... file a ticket about making it optional or not. I believe that the shell integration / autocomplete is where they started the product so it's probably one of those core features in the product team's minds.
I generally like the integration but in some cases it's getting in the way of other ai that is runnin q to quit and all of a sudden its in q... I renamed it to amazonq and removed it from my zshrc and added it as a command to integrate, amazonqinit
