## What it does

The skill triggers when you are designing, prototyping or rewriting a desktop app for macOS and Windows (optionally Linux) and it has to feel native to users. Inside: the architecture philosophy, layer breakdown, IPC contract, WebView survival notes, memory truths and native conventions. The material comes from Raycast's public write-up on their 2.0 rewrite and was checked by reverse-engineering their shipping macOS binary.

How it works: you start with `references/01-philosophy.md` and its eight tenets, then load only the file you need — `02-architecture.md` for layers, `03-webview-survival.md` for flicker and stutter in hidden windows, `04-ipc-contract.md` for typing IPC across Rust, Swift, C# and TypeScript, `05-memory-truths.md` for memory measurements, `06-native-conventions.md` for what gives a webpage away. Before recommending an architecture it runs your project through `checklists/decision-tree.md`, and before you claim the app feels native it runs `checklists/ship-readiness.md`, a 30-item audit.

Worth knowing: the skill talks you out of some paths. Reach for Electron and just theme it, or pick Tauri because it is lighter, and it will tell you that you lose control over the system WebView, the window class and the material APIs. Fine for utilities, not for an app where every window animation has to match the OS. It also stays away from pure web apps and mobile.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add yetone/native-feel-skill --skill native-feel-cross-platform-desktop -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/native-feel-cross-platform-desktop/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/native-feel-cross-platform-desktop/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add yetone/native-feel-skill --skill native-feel-cross-platform-desktop -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/native-feel-cross-platform-desktop/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add yetone/native-feel-skill --skill native-feel-cross-platform-desktop -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/native-feel-cross-platform-desktop/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install yetone/native-feel-skill native-feel-cross-platform-desktop
```

2. **Manually: put the files in place**

gemini skills install https://github.com/yetone/native-feel-skill
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/native-feel-cross-platform-desktop/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add yetone/native-feel-skill --skill native-feel-cross-platform-desktop -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/yetone/native-feel-skill/tree/HEAD/SKILL.md

## When to use it
- pick an architecture for a desktop app on macOS and Windows
- debug why a WebView flickers or freezes when the window is hidden
- type IPC across Rust, Swift, C# and TypeScript from one contract
- check whether 400 MB in Activity Monitor is a real number
- strip the UI habits that make an app read as a webpage

## Example prompts
- Design the architecture for a cross-platform desktop app that feels native — which layers do I need?
- Why does my WKWebView freeze when the window is hidden? What do I fix?
- Run my project through the decision tree: should I even use this architecture?

# Native-Feel Cross-Platform Desktop

You are advising on the architecture of a cross-platform desktop app that must *feel native*. This skill captures the philosophy, architecture, and concrete pitfalls — distilled from Raycast's public technical deep-dive on their 2.0 rewrite and verified by reverse-engineering the shipping `Raycast Beta.app` binary on macOS.

## How to use this skill

1. **Start with the philosophy in `references/01-philosophy.md`.** It frames the central tension this architecture resolves — *how to get cross-platform DX and near-native performance at the same time* — and gives you eight tenets that name the structural moves. Every concrete decision later flows from one of those tenets. If the user is making a decision that contradicts a tenet, surface the tenet by number and short name and explain the trade-off.
2. **Match the user's question to a reference file.** Don't dump the whole skill — load only what's needed:
   - Architecture / "which layers should I have?" → `references/02-architecture.md`
   - "Why does my WebView flicker / stutter / freeze when hidden?" → `references/03-webview-survival.md` (the highest-density file — every item is a real bug with a real fix)
   - "How do I type my IPC across Rust/Swift/C#/TS?" → `references/04-ipc-contract.md`
```
