## 💎 What This Is

**hyperdroid-skill** is an elite Claude Code plugin for Android development—from debugging a misbehaving app to building entire custom ROMs. Whether you're a hobbyist flasher or a full-time ROM maintainer, these skills have you covered.

Instead of digging through Stack Overflow and XDA threads, get **domain expertise** directly:

- A **device debugger** who knows logcat, tombstones, and ANR traces inside-out
- A **fastboot specialist** who handles A/B slots, dynamic partitions, and brick prevention
- A **build engineer** who speaks Gradle, Soong, and `lunch` fluently
- A **LineageOS contributor** who knows Gerrit, repopick, and breakfast by heart

Works with Claude Code and any agent supporting the plugin ecosystem.

## 🔮 Skills

Skills are contextual knowledge bundles that auto-activate when relevant. Ask about "adb logcat"? The android skill loads. Mention "flash boot image"? Bootloader skill activates.

| Skill | Domain | Triggers |
|-------|--------|----------|
| `android` | Device Mastery | ADB, logcat, shell, app management, UI automation, debugging |
| `android-fastboot` | Danger Zone | Fastboot, partitions, A/B slots, recovery, Magisk, unlocking |
| `android-build` | Build Systems | Gradle CLI, SDK manager, AOSP envsetup/lunch/m, kernels |
| `lineageos` | Custom ROMs | breakfast/brunch, repopick, Gerrit, vendor blobs, porting |

### 🎯 `android` — Device Mastery

Everything about interacting with Android devices via ADB:

- **Connection** — USB, wireless (`adb tcpip`), multi-device targeting
- **Shell** — Commands, root access, file push/pull, port forwarding
- **App Management** — Install, uninstall, start/stop activities, permissions, intents
- **UI Automation** — Tap, swipe, text input, screenshots, screen recording
- **Debugging** — Logcat filtering, crash analysis, memory profiling, strict mode
- **System Inspection** — dumpsys, getprop, /proc exploration, service calls

### ⚠️ `android-fastboot` — Danger Zone

Fastboot and bootloader operations with appropriate safety warnings:

- **Fastboot Commands** — Flash, erase, boot, getvar, reboot modes
- **Bootloader State** — Unlock, lock, OEM commands, critical partitions
- **A/B Partitions** — Slot switching, dynamic partitions (super), metadata
- **Recovery** — TWRP, stock recovery, sideload, OTA survival
- **Root** — Magisk installation, boot image patching, module management
- **Brick Prevention** — Backup strategies, critical partition protection, recovery paths

### 🔧 `android-build` — Build Systems

Both app and ROM building expertise:

- **Gradle CLI** — Tasks, variants, dependency resolution, build optimization
- **SDK Tools** — sdkmanager, avdmanager, emulator management
- **AOSP Build** — envsetup.sh, lunch targets, m/mm/mmm, ninja
- **Device Trees** — Makefile structure, BoardConfig, device props
- **Kernel Building** — Defconfig, cross-compilation, module building

### 🌙 `lineageos` — Custom ROM Development

LineageOS-specific development workflows:

- **Source Management** — repo init/sync, local manifests, breakfast
- **Building** — brunch, target selection, signed builds
- **Gerrit Workflow** — repopick, topic branches, code review
- **Vendor Blobs** — extract-files.sh, proprietary-files.txt, TheMuppets
- **Device Porting** — Common trees, inheritance, bring-up process
- **Contributing** — Commit style, Gerrit etiquette, LineageOS standards

## 🦋 Agents

Agents are invoked via the Task tool with `subagent_type="hyperdroid:agent-name"`.

| Agent | Specialty |
|-------|-----------|
| `hyperdroid:crash-analyzer` | Autonomous crash investigation — collects logs, tombstones, ANR traces, analyzes native crashes, provides root cause diagnosis |

### Crash Analyzer

When your app or device is misbehaving, this agent:

1. Collects relevant logcat output with intelligent filtering
2. Retrieves tombstones and native crash dumps
3. Parses ANR traces and identifies blocked threads
4. Correlates crashes with recent changes
5. Provides actionable diagnosis and fix suggestions

```
> My app keeps crashing on startup
[crash-analyzer agent activates, gathers evidence, returns diagnosis]
```

## 🎯 Usage

Skills activate automatically based on context:

```
> Connect to my Android device wirelessly
[android skill activates — guides through adb tcpip setup]

> Flash the custom boot image I just built
[android-fastboot skill activates — provides safe fastboot workflow]

> Build LineageOS for my Pixel 8
[lineageos skill activates — walks through breakfast/brunch process]

> Why does my app crash when rotating the screen?
[crash-analyzer agent investigates lifecycle issues]
```

Or invoke directly:

```bash
/hyperdroid-skill:android              # Device interaction guidance
/hyperdroid-skill:android-fastboot   # Fastboot and recovery
/hyperdroid-skill:android-build        # Build system expertise
/hyperdroid-skill:lineageos            # Custom ROM development
```

## 💜 Philosophy

These skills embody the Android power-user methodology:

| Principle | What It Means |
|-----------|---------------|
| **Know the internals** | Understanding dumpsys, getprop, and /proc makes you dangerous |
| **Respect the danger** | Bootloader operations get explicit warnings — we don't brick devices |
| **Build from source** | Whether app or ROM, know your build system inside-out |
| **Debug systematically** | Logcat + tombstones + ANR traces = root cause, not guesswork |
| **Give back** | LineageOS thrives on contributors — learn the Gerrit workflow |

## 📚 Reference Materials

The `research/` directory contains extensive reference documentation used during skill development:

- **ADB mastery** — Every flag, every trick
- **Fastboot internals** — Partition tables, A/B mechanics
- **AOSP build system** — Soong, ninja, make
- **Kernel building** — Defconfigs, modules, GKI
- **Debugging tools** — Perfetto, simpleperf, memory analysis
