1# Closed-Loop Analytics Upgrade
2 
3## Principle
4 
5A workflow is not a closed loop until it checks whether the change worked and updates the playbook from that evidence.
6 
7For marketing skills, that means pulling analytics after the change window. Manual opinions are useful. Platform truth wins.

9## Core pattern

111. **Input**: usage logs, recommendations, shipped changes, platform analytics, owner feedback, and cost/runtime data.
122. **AI action**: compare baseline vs candidate, find repeatable signals, and propose a skill/playbook patch.
133. **Output**: candidate patch to a prompt, skill, connector, brief template, scoring rubric, or next-action rule.
144. **Judgment**: success rate, speed, cost, quality, human correction rate, and actual performance delta.
155. **Self-improvement**: promote only if it beats baseline. Otherwise keep testing, rollback, or mark unproven.
