Adaptive Task Routing assesses conversation, model and reasoning resources at meaningful task boundaries. It shows the action to take now before a concise reason, distinguishing task-fit settings from whether a switch is worthwhile. Keeping a suitable setup and retaining provisionally under uncertainty are separate outcomes. Default ask confirms proposed changes or material blockers; retention and nonblocking defer continue only already authorized work. Plan-only requests never authorize implementation. Auto applies only justified, authorized, callable and verifiable changes. Compact uses a plain heading and one conversation sentence. Verified keep shows only the observed current AI; detailed adds task-fit alternatives, minimum settings and upgrade rationale. Ordinary changes ask only about the target setting. Actual savings and reliability improvements require evidence.
