Specialist development utilities — testing, optimization, and tooling skills that aren't specific to project documentation
npx claudepluginhub ichabodcole/project-docs-scaffold-template --plugin toolboxTrigger on any request to build a mockup, prototype, or rough visual of a UI — especially when the goal is design exploration before implementation. Use when someone wants to SEE what something could look like: sketching out a flow, visualizing multiple UI states (idle/loading/error/success), comparing two layout options, or building a clickable preview before writing real code or a proposal. Also invoke proactively when reading a proposal, investigation, or design resolution that contains complex or undecided UI — suggest a prototyping step before locking in an implementation plan. The output is a self-contained interactive HTML file, not production code. Do NOT invoke for implementing real UI components, adding states to existing code, reviewing designs, or answering general UX questions.
Write and run Maestro flows for automated testing of mobile apps, WebViews, and web browsers. Covers flow file YAML syntax, element selectors, CLI commands, simulator/emulator setup, web browser testing, debugging, and project structure. Use when the user needs to automate mobile UI testing, write Maestro flow files, set up simulators for testing, debug failing flows, or test web apps with Maestro. Triggers when user says "test the mobile app", "write a Maestro flow", "run Maestro tests", "set up iOS simulator for testing", "automate mobile UI", "debug Maestro flow", "Maestro web testing", or wants to create or run automated tests with Maestro. For cross-browser web testing (Firefox, Safari), use Playwright instead.
This skill should be used when the user asks to "optimize screenshots", "convert screenshots to WebP", "compress images for the repo", "save screenshots as WebP", or when capturing documentation screenshots that should be stored efficiently. Converts PNG screenshots to WebP format using sharp-cli via npx.

Use this agent when you need expert assistance with React Native development tasks including code analysis, component creation, debugging, performance optimization, or architectural decisions. Examples: <example>Context: User is working on a React Native app and needs help with a navigation issue. user: 'My stack navigator isn't working properly when I try to navigate between screens' assistant: 'Let me use the react-native-dev agent to analyze your navigation setup and provide a solution' <commentary>Since this is a React Native specific issue, use the react-native-dev agent to provide expert guidance on navigation problems.</commentary></example> <example>Context: User wants to create a new component that follows the existing app structure. user: 'I need to create a custom button component that matches our app's design system' assistant: 'I'll use the react-native-dev agent to create a button component that aligns with your existing codebase structure and design patterns' <commentary>The user needs React Native component development that should follow existing patterns, so use the react-native-dev agent.</commentary></example>
