Git pauses on the branches you protect.02Sphinx asks.A reviewer that never saw your chat reads the diff and asks what the change does when things go wrong.03You answer.Get it wrong and you learn why, then try a new scenario. Get it right and the push continues.Works with Codex, Claude Code, Cursor, OpenCode, and Pi, or plain Git. Your answers never reach the coding agent, and .env files and keys are never opened. In a hurry?
