Zwischen Information

Claude Code moves fast – by reading less than it should, building on assumptions it never checked, and stopping the moment the output looks plausible. Everything looks done. Then you start reading: files changed without being fully understood, fixes stacked on fixes; none of them verified. That's vibe code in short. Zwischen puts a second AI inside your Claude Code session. Every read, tool call, file write, and next step gets reviewed before it executes. If the move is easy/cheap instead of correct, it's blocked. The agent is forced to go back and do the work. You choose the adversarial model – GPT, Gemini, DeepSeek, or Claude. We call the adversary "Frank." His job: keep Claude honest during the session, before the shortcuts turn your team into a full time AI clean-up crew.
