droid
This skill should be used when the user asks to "test Android app", "automate Android emulator", "tap button on Android", "take Android screenshot", "interact with Android UI", "ADB automation", "fill Android form", "swipe on emulator", "validate Android UI flow", or needs to control an Android device/emulator via ADB. Provides a unified CLI with JSON output optimized for LLM consumption.
What this skill does
# Droid Unified Android testing tool with **JSON output** for LLM-friendly automation. ## CLI Discovery The CLI is located at `./droid-cli/` relative to this SKILL.md file. | Platform | Script | | ---------------- | ------------------------------------------ | | Unix/Linux/macOS | `droid` | | Windows | `droid.cmd` (`droid.ps1` also available) | ## Prerequisites - Bun runtime (https://bun.sh) - ADB (Android Debug Bridge) in PATH - Connected Android device or running emulator - USB debugging enabled on device ## Quick Start ```bash # Check device connection droid info # Screenshot + UI elements (most useful command) droid screenshot # Tap by text (no coordinates needed!) droid tap -t "Book Now" # Fill a form field in one command droid fill "Email" "[email protected]" # Wait for element to appear droid wait-for -t "Success" -s 5 ``` ## Core Commands ### screenshot Capture screenshot AND UI elements. Returns element coordinates for tapping. ```bash droid screenshot droid screenshot --clickable # Only clickable elements droid screenshot --no-ui # Fast, no element dump ``` **Response:** `{"ok":true,"screenshot":"/tmp/screenshot.png","elements":[{"text":"Book","class":"Button","clickable":true,"x":540,"y":350,"bounds":[400,300,680,400]}]}` ### tap Tap by text or coordinates. ```bash droid tap -t "Book Now" # By text droid tap -t "State" --prefer-input # Prefer input fields over labels droid tap -t "Submit" --clickable # Only clickable elements droid tap 540 960 # By coordinates ``` ### fill Fill text field in one command (tap + clear + type + hide-keyboard). ```bash droid fill "Enter your email" "[email protected]" ``` ### wait-for Wait for element to appear (with timeout). ```bash droid wait-for -t "Welcome" -s 10 # Returns: {"ok":true,"found":true,"element":{...}} or {"ok":true,"found":false,"timeout":true} ``` ## Form Workflow Commands ### clear / type / hide-keyboard ```bash droid clear # Clear focused field droid type "[email protected]" # Type into focused field droid hide-keyboard # Dismiss keyboard (use instead of 'key back') ``` ### key Send key events. | Key | Purpose | |-----|---------| | `back` | Navigate back | | `enter` | Submit/confirm | | `move_home` | Cursor to start of text | | `move_end` | Cursor to end of text | | `delete` | Backspace | | `app_home` | Android home screen | ```bash droid key back droid key move_home ``` ## Other Commands | Command | Purpose | Example | |---------|---------|---------| | `swipe` | Scroll | `droid swipe up` | | `longpress` | Long press | `droid longpress -t "Item"` | | `launch` | Launch app | `droid launch com.example.app` | | `current` | Current activity | `droid current` | | `info` | Device info | `droid info` | | `wait` | Wait ms | `droid wait 1000` | | `select-all` | Select text | `droid select-all` | See `references/commands.md` for full documentation. ## Testing Workflow ### Recommended Pattern ```bash # 1. Screenshot to see current state droid screenshot # 2. Read the screenshot image with Claude's Read tool # 3. Tap by text when possible droid tap -t "Book Now" -w 1000 # 4. Verify the action worked droid wait-for -t "Booking Confirmed" -s 5 ``` ### Form Filling Pattern ```bash # Use fill command for efficiency droid fill "Email" "[email protected]" droid fill "Password" "secret123" droid tap -t "Sign In" --clickable droid wait-for -t "Welcome" -s 10 ``` ### Tips - **Use `--prefer-input`** when tapping form fields to avoid hitting labels - **Use `--clickable`** when tapping buttons to ensure element is interactive - **Use `hide-keyboard`** not `key back` to dismiss keyboard - **Use `wait-for`** instead of blind `wait` for reliable verification ## Error Handling All errors return JSON with `"ok":false`: ```bash droid tap -t "NonexistentButton" # {"ok":false,"error":"No element found matching 'NonexistentButton'"} ```

contribute
IncludedLocal-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".
architectural-analysis
IncludedUser-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).
mcp

Capabilities: build MCP servers, integrate external APIs, discover/execute MCP tools, manage multi-server configs, design agent-centric tools. Actions: create, build, integrate, discover, execute, configure MCP servers/tools. Keywords: MCP, Model Context Protocol, MCP server, MCP tool, stdio transport, SSE transport, tool discovery, resource provider, prompt template, external API integration, Gemini CLI MCP, Claude MCP, agent tools, tool execution, server config. Use when: building MCP servers, integrating external APIs as MCP tools, discovering available MCP tools, executing MCP capabilities, configuring multi-server setups, designing tools for AI agents.
react-native-skia
IncludedDesign, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.
plaid
IncludedProduct Led AI Development — guides founders from idea to launched product. Six capabilities: Idea (discover a product idea), Validate (pressure-test the idea against fatal flaws, problem reality, competition, and 2-week MVP feasibility), Plan (vision intake + document generation), Design (translate image references into a design.md spec), Launch (go-to-market strategy), and Build (roadmap execution). Use when someone says "PLAID", "plaid idea", "help me find an idea", "product idea", "idea from my business", "idea from my expertise", "plaid validate", "validate my idea", "pressure-test", "is this idea good", "find fatal flaws", "validate the problem", "plan a product", "define my vision", "generate a PRD", "product strategy", "plaid design", "design from image", "translate image to design", "create design.md", "extract design tokens", "plaid launch", "go-to-market", "launch plan", "GTM strategy", "launch playbook", "plaid build", "build the app", "start building", or "execute the roadmap".
nextjs-framer-motion-animations
IncludedAdds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
