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

# xtool Plugin

## Overview

This plugin provides guidance for Xcode-free iOS development using xtool. It helps build SwiftPM-based iOS apps on Linux, Windows, and macOS without requiring Xcode.

## Skills Included

### using-xtool (Main Skill)

Auto-detects when working with:
- xtool projects or configuration
- SwiftPM iOS apps
- iOS development on non-macOS platforms
- App extensions (widgets, share, keyboard, etc.)

## Key Patterns

### xtool is NOT XcodeGen

This is the most critical distinction. xtool:
- Uses `xtool.yml` (not `project.yml` or `Project.swift`)
- Uses standard SwiftPM `Package.swift`
- Uses `xtool dev` command (not `xtool build` or `xtool run`)
- Places extensions in `Sources/` (standard SwiftPM, not `Extensions/`)

### Project Structure

```
MyApp/
├── Package.swift          # SwiftPM package definition
├── xtool.yml              # xtool configuration
├── Sources/
│   ├── MyApp/             # Main app target
│   └── MyWidget/          # Extension targets
└── *-Info.plist           # Optional custom plists
```

### App Extensions Pattern

Extensions require:
1. `.library` product + target in Package.swift (not `.executable`)

How to install

The exact contents, by fingerprint
mdr add 2389-research/xtool/CLAUDE.md@sha256:9bfae99dcde77579

The line at the top of this page pins the label git:20260102.aa21abb, 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.
