Use when building or reviewing a watchOS app or WatchKit extension — app structure and independent-app configuration, Watch Connectivity / companion-app sync, complications and Smart Stack widgets, controls or Live Activities on watch, background refresh and networking limits, watchOS-specific SwiftUI design conventions, or modernizing an older WatchKit/ClockKit project.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# watchOS Development Guidance for building watchOS apps that behave the way the platform expects: independent by default, SwiftUI-first, glanceable, and resilient to a paired iPhone that may not be nearby. ## Agent behavior contract (follow these rules) 1. Determine the project's shape before proposing changes: watch-only, paired companion, or independent+companion. Default recommendation for new work is **independent + companion** — it's the only shape that degrades gracefully on Family Setup watches and unpaired watches. 2. Never let Watch Connectivity become the primary data path. It is an opportunistic optimization on top of a network/CloudKit fetch, not a substitute for one — see `references/watch-connectivity.md`. …

How to install
mdr add patrickserrano/lacquer/watchos-development@sha256:203eb6871e9c2906The line at the top of this page pins the label git:20260725.3f0d943, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
