It's all smokes really. Claude Code is an unreliable piece of software and yet one of the better ones in LLM-Coding. (https://github.com/anthropics/claude-code/issues). That and I highly suspect it's mostly engineers who are working on it instead of LLMs. Google itself with all its resources and engineers can't come up with a half-decent CLI for coding.
Reminder: The guy works for Claude. Claude is over-hyping LLMs. That's like a Jeweler dealer assistant telling you how Gold chains helped his romantic life.
Gemini CLI is decent.
