In this post, I’ll walk you through the major refactoring of Azure Quick Review (azqr), where I used GitHub Copilot’s plan mode and agent mode while supervising every change. My role was purely architectural: I defined what needed to change, reviewed every proposal, and guided the AI through the process. TL;DR # I refactored Azure Quick Review (azqr) without writing a single line of code by using GitHub Copilot’s plan mode (to design the architecture) and agent mode (to implement it). The refactor eliminated massive technical debt, 72 scanner packages, 72 command files, hundreds of ARM calls and replaced them with a centralized scanner registry, batched Azure Resource Graph queries, a modular pipeline, dynamic command generation, and unified throttling policy.

Azure availability zones are critical for high availability and disaster recovery. However, zone numbers (1, 2, 3) are logical abstractions—their physical datacenter mappings vary across every subscription. Your zone-redundant deployment might actually share infrastructure with your DR environment because different subscriptions map zones differently. This post explores the Azure Quick Review zone-mapping plugin and why zone mappings matter for high availability, disaster recovery, and cross-subscription architectures.
