swiftui-macos SKILL.md skillA
swiftui-macos from kageroumado/swiftui-macos-skill is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add kageroumado/swiftui-macos-skill/swiftui-macos@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Expert SwiftUI guidance for macOS apps — covers writing and reviewing code with runtime-level understanding of observation, concurrency, performance, and platform integration. Use when user asks to "build a SwiftUI view", "review my SwiftUI code", "fix observation issues", "bridge AppKit", "architect state management", "debug view updates", or works on any macOS SwiftUI project — building features, reviewing existing code, debugging view updates or performance, fixing concurrency issues…
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
Guide SwiftUI development for macOS apps. Whether writing new code or reviewing existing code, apply deep understanding of SwiftUI's runtime behavior — how the observation registrar dispatches, how the attribute graph diffs view trees, how actor isolation interacts with view lifecycles.
## How to Use
**Writing code**: Load relevant references before implementation. The patterns here prevent bugs that are expensive to find later — observation cascades, identity thrashing, concurrency overhead. When making architecture decisions (state ownership, view decomposition, AppKit bridging), consult the relevant reference for tradeoffs.
**Reviewing code**: Check each reference area systematically. Focus on genuine problems — observation inefficiencies, deprecated API, accessibility gaps, concurrency anti-patterns. Don't flag obvious issues or invent problems.
**Partial scope**: Load only what the task needs. Not every change requires all eight references.
## References
| Reference | Load when |
|---|---|
| `references/observation.md` | `@Observable`, `@State`, `ForEach`, data-driven views, `Observations {}` streams |

How to install
mdr add kageroumado/swiftui-macos-skill/swiftui-macos@sha256:39b6ddd4311af34aThe line at the top of this page pins the label v1.0.0, 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.
