Outer loop vs inner loop: why your context-fetching agent shouldn't do dev, review, or verification

A Japanese long-form post lays out a two-loop architecture for multi-agent work: context-fetching agents (like a Grok Bot) belong to the 'outer loop' whose only job is gathering external context and handing it to the 'inner loop' (e.g. Cursor Projects) where a coordinator agent owns the work. Letting the outer loop do development, verification, or review collapses responsibility boundaries — like a manager who's never seen the kitchen jumping in to cook. The outer loop doesn't know on-the-ground facts and rules, so intervening makes both loops malfunction. The takeaway: designing clear responsibility boundaries between loops is the prerequisite for agents that fetch info and decide autonomously.
