# Upgrade Setup

> Power-user tool — normally invoked via /checkup. Re-apply current best practices to an existing onboarding-agent setup. Detects the original setup, computes per-section diffs against the latest templates, asks for per-change confirmation with a unified-diff preview, backs up everything it will touch, and never touches content outside the plugin's delimited sections. Supports --dry-run.
