Jetski is a code name.
replyAnd it was replaced (I expect, don’t know for sure) because GeminiCLI was built on a code base and language that didn’t scale in performance for what people were doing.
I know Gemini CLI was written in JS + React. Even the public version had a very slow startup time that some might blame on the stack. But Claude CLI is a similar stack and starts instantly, so idk, does Bun really make the difference?
replyInternally I didn't like Gemini CLI just because it didn't have the right skills/whatever preinstalled, so it always did stuff that made sense elsewhere but not at Google, like trying to grep through the entire monorepo. Jetski just worked.
