Native SwiftUI WebKit integration with the new WebView struct and WebPage observable class. Covers WebView creation from URLs, WebPage for navigation control and state management, JavaScript execution (callJavaScript with arguments and content worlds), custom URL scheme handlers, navigation management (load, reload, back/forward), navigation decisions, text search (findNavigator), content capture (snapshots, PDF generation, web archives), and configuration (data stores, user agents, JS permissions). Use when embedding web content in SwiftUI apps instead of the old WKWebView + UIViewRepresentable/NSViewRepresentable bridge pattern. This is a brand new API — do NOT use the old WKWebView wrapping approach.
Skill for creating Lucid agents with JavaScript handler code. Shows three options: MCP tool with SIWE, SDK with your wallet, or viem with custom signing. Teaches JS handler code contract, paymentsConfig, and identityConfig. Activate when: user wants to create Lucid agents with inline JS handlers (no generate API, no self-hosting). The agent will be hosted on the Lucid platform.
Debug TypeScript/JavaScript with Bun inspector
Use when mocha test structure, hooks, and async testing patterns for JavaScript testing.
Use this agent when you need to review JavaScript or Stimulus frontend code changes with a special eye for race conditions. The agent should be invoked after implementing JavaScript features, modifying existing JavaScript code, or when creating or modifying Stimulus controllers. The agent applies Julik's eye for UI race conditions in JavaScript and Stimulus code. Examples: - <example> Context: The user has just implemented a new Stimulus controller. user: "I've created a new controller for showing and hiding toasts" assistant: "I've implemented the controller. Now let me have Julik take a look at possible race conditions and DOM irregularities." <commentary> Since new Stimulus controller code was written, use the julik-frontend-races-reviewer agent to apply Julik's uncanny knowledge of UI data races and quality checks in JavaScript and Stimulus code. </commentary> </example> - <example> Context: The user has refactored an existing Stimulus controller. user: "Please refactor the controller to slowly animate...
TypeScript/JavaScript testing practices with Bun's test runner. Activate when working with bun test, .test.ts, .test.js, .spec.ts, .spec.js, testing TypeScript/JavaScript, bunfig.toml, testing configuration, or test-related tasks in Bun projects.
TypeScript/JavaScript project workflow guidelines using Bun package manager. Triggers on `.ts`, `.tsx`, `bun`, `package.json`, TypeScript. Covers bun run, bun install, bun add, tsconfig.json patterns, ESM/CommonJS modules, type safety, Biome formatting, naming conventions (PascalCase, camelCase, UPPER_SNAKE_CASE), project structure, error handling, environment variables, async patterns, and code quality tools. Activate when working with TypeScript files (.ts, .tsx), JavaScript files (.js, .jsx), Bun projects, tsconfig.json, package.json, bun.lock, or Bun-specific tooling.
Use when developing custom Checkstyle checks, filters, and plugin integrations for project-specific Java code standards.
Develop custom WebF native plugins based on Flutter packages. Create reusable plugins that wrap Flutter/platform capabilities as JavaScript APIs. Use when building plugins for native features like camera, payments, sensors, file access, or wrapping existing Flutter packages.
Write TypeScript and JavaScript code like a top engineer using functional programming principles. Use when writing new code, reviewing existing code, or refactoring TS/JS projects. Applies pure functions, immutability, function composition, higher-order functions, declarative style, and avoiding shared state using native patterns only (no external libraries). Always analyzes the existing codebase first to understand patterns and conventions before making changes or suggestions.
Write and review API documentation comments using TSDoc and JSDoc best practices. Use when the user asks for docs, doc comments, TSDoc, JSDoc, @param/@returns help, or documentation quality improvements in JavaScript or TypeScript code.
Create and register Stimulus controllers for interactive JavaScript features. Use when adding client-side interactivity, dynamic UI updates, or when the user mentions Stimulus controllers or JavaScript behavior.
