lessons from shipping a native mac app on a multi-agent workflow: 5 things i'd do differently

The developer shipped v3.0 of Buffer, a native Swift/AppKit clipboard manager for Mac, which was built using a multi-agent workflow. This workflow involved Claude Code as the main driver and a second model, Opencode, as a dedicated reviewer for the same diffs. The release includes an interactive image canvas with pinch/pan/zoom for copied screenshots, clipboard noise filtering, history tiers, and in-app update notes.
