It's not an IDE, it's a way to run agents. In particular, the Antigravity CLI positioned as Gemini CLI's successor is a shell with superpowers, not something you would use for code development.
Any CLI-based coding agent can equally well be described as "a shell with superpowers", and people were using Claude Code for non-coding tasks (e.g. sysadmin) before OpenClaw appeared and made that it's main purpose.
