Xcode	16+	iOS app development (macOS only)
Java	17+	Android build toolchain

Setting Up the Gateway (`core/`)

cd core/
uv sync                    # Install dependencies
uv run antimatter-gateway start   # Run in dev mode

Gateway Dev Commands

Command	Purpose
`uv run antimatter-gateway start`	Start gateway
`uv run antimatter-gateway pair`	Generate pairing QR
`uv run antimatter-gateway status`	Check status
`uv run pytest`	Run tests
`uv run ruff check .`	Lint
`uv run mypy .`	Type check

Setting Up Adapters

AG Adapter (TypeScript)

cd adapters/ag/
npm install
npm run watch     # esbuild watcher
# Press F5 in VS Code to launch Extension Development Host

Command	Purpose
`npm run lint`	TypeScript type-check (`tsc --noEmit`)
`npm run build`	Production bundle
`npm run package`	Package `.vsix`

AG2 Adapter (Python)

cd adapters/ag2/
uv sync
uv run antimatter-ag2     # Dev mode

CC Adapter (Node.js)

cd adapters/cc/
npm install
npm run dev       # Watch mode

Setting Up the Android App

Open the android/ directory in Android Studio Koala or newer.
Wait for Gradle sync to complete.
Select the app run configuration.
Run on a connected device or emulator (API 26+).

Android Commands

cd android/

# Lint
./gradlew lintDebug

# Unit tests
./gradlew testDebugUnitTest

# Build debug APK
./gradlew assembleDebug

# Install on connected device
./gradlew installDebug

Setting Up the iOS App

cd ios/
open AntimatterApp.xcworkspace    # Xcode 16+
# ⌘R to build and run

SPM packages are resolved automatically by Xcode.

Working on the Documentation

The docs site is an Astro/Starlight project in docs-site/:

cd docs-site/
npm install
npm run dev       # Live preview at http://localhost:4321
npm run build     # Production build
npm run preview   # Preview production build

Documentation pages are in src/content/docs/ as .mdx files. Navigation is defined in astro.config.mjs.

Submitting a Pull Request

Fork the repository and clone your fork.
Create a feature branch from main:
Terminal window
```
git checkout -b feat/my-feature
```
Make your changes and ensure:
- Android: ./gradlew lintDebug passes with no new errors.
- TypeScript adapters: npm run lint passes.
- Python: ruff check . and mypy . pass.
Write a clear PR description explaining what changed and why.
Open the pull request against main.

Code Style

Component	Tool	Config
TypeScript	ESLint + Prettier	`adapters/ag/.eslintrc.js`
Python	Ruff + Mypy	`core/pyproject.toml`
Kotlin	Ktlint	`android/` (enforced by Gradle plugin)
Swift	SwiftFormat	`ios/.swiftformat`

Please configure your IDE to respect these rules. PRs that fail linting will not be merged.
