## What it does

The skill lays down rules for menubar utilities: the app stays menubar-only unless told otherwise, with `LSUIElement` set to `true`. Transport and decoding logic belongs outside SwiftUI views, and state transitions live in a store layer such as `@Observable`. Tuist manifests are the source of truth, so hand-editing generated Xcode artifacts is off the table.

Files get fixed roles: `Project.swift` for the target and settings, then separate files for models, client, store, and the menu and row views. Local runs go through `run-menubar.sh` and `stop-menubar.sh`. The run script restarts an existing instance before relaunching and does not pop Xcode open; generation uses `tuist generate --no-open`, and builds use `TUIST_SKIP_UPDATE_CHECK=1 tuist xcodebuild build` rather than raw `xcodebuild`.

Work order matters. Confirm Tuist owns the project, then probe the backend with `curl` — response shape, auth, pagination. If the endpoint ignores `limit/page`, the skill advises pulling the full list and trimming it in the store. Layers go bottom to top: models, client, store, views last. `tuist run` often fails to resolve a macOS destination, which is why the scripts are the canonical launch path.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Dimillian/Skills --skill macos-menubar-tuist-app -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/macos-menubar-tuist-app/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/macos-menubar-tuist-app/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Dimillian/Skills --skill macos-menubar-tuist-app -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/macos-menubar-tuist-app/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Dimillian/Skills --skill macos-menubar-tuist-app -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/macos-menubar-tuist-app/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Dimillian/Skills macos-menubar-tuist-app
```

2. **Manually: put the files in place**
- File: `.github/skills/macos-menubar-tuist-app/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Dimillian/Skills --skill macos-menubar-tuist-app -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Dimillian/Skills --path macos-menubar-tuist-app
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/macos-menubar-tuist-app/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Dimillian/Skills --skill macos-menubar-tuist-app -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Dimillian/Skills/tree/HEAD/macos-menubar-tuist-app/SKILL.md

## When to use it
- build a menubar utility on Tuist without touching generated project files
- move networking and decoding out of SwiftUI view bodies
- survive API field changes without breaking model decoding
- fix local launch when `tuist run` cannot resolve the macOS target
- re-run build and script checks after edits

## Example prompts
- build a Tuist menubar app with models, client, store and menu views
- rewrite the API decoding so extra fields don't break it
- fix `run-menubar.sh` so it restarts the old instance and skips Xcode

description: Build, refactor, or review macOS menubar apps that use Tuist and SwiftUI. Use when creating or maintaining LSUIElement menubar utilities, defining Tuist targets/manifests, implementing model-client-store-view architecture, adding script-based launch flows, or validating reliable local build/run behavior without Xcode-first workflows.

# macos-menubar-tuist-app

Build and maintain macOS menubar apps with a Tuist-first workflow and stable launch scripts. Preserve strict architecture boundaries so networking, state, and UI remain testable and predictable.

## Core Rules

- Keep the app menubar-only unless explicitly told otherwise. Use `LSUIElement = true` by default.
- Keep transport and decoding logic outside views. Do not call networking from SwiftUI view bodies.
- Keep state transitions in a store layer (`@Observable` or equivalent), not in row/view presentation code.
- Keep model decoding resilient to API drift: optional fields, safe fallbacks, and defensive parsing.
- Treat Tuist manifests as the source of truth. Do not rely on hand-edited generated Xcode artifacts.
- Prefer script-based launch for local iteration when `tuist run` is unreliable for macOS target/device resolution.
- Prefer `tuist xcodebuild build` over raw `xcodebuild` in local run scripts when building generated projects.

## Expected File Shape

Use this placement by default:

- `Project.swift`: app target, settings, resources, `Info.plist` keys
- `Sources/*Model*.swift`: API/domain models and decoding
- `Sources/*Client*.swift`: requests, response mapping, transport concerns
- `Sources/*Store*.swift`: observable state, refresh policy, filtering, caching
- `Sources/*Menu*View*.swift`: menu composition and top-level UI state
- `Sources/*Row*View*.swift`: row rendering and lightweight interactions
- `run-menubar.sh`: canonical local restart/build/launch path
- `stop-menubar.sh`: explicit stop helper when needed

## Workflow

1. Confirm Tuist ownership
- Verify `Tuist.swift` and `Project.swift` (or workspace manifests) exist.
- Read existing run scripts before changing launch behavior.

2. Probe backend behavior before coding assumptions
- Use `curl` to verify endpoint shape, auth requirements, and pagination behavior.
- If endpoint ignores `limit/page`, implement full-list handling with local trimming in the store.

3. Implement layers from bottom to top
