Core best practices for the Dinero.js money library. Use when writing, reviewing, or refactoring code that creates Dinero objects, performs arithmetic on monetary values, or handles money in JavaScript/TypeScript. Triggers on imports from 'dinero.js', monetary calculations, or price/cost handling logic.
Guide for building applications with Gea — a lightweight, reactive JavaScript UI framework with proxy-based stores, JSX components, and automatic DOM patching. Use when creating components, stores, or working with Gea's reactivity system.
Fast, accurate, DOM-free text measurement and layout library for JavaScript/TypeScript supporting multiline, rich-text, and variable-width layouts.
Prototype pollution testing for JavaScript stacks. Use when user input is merged into objects (query parsers, JSON bodies, deep assign), when configuring libraries via untrusted keys, or when hunting RCE gadgets via polluted Object.prototype in Node or the browser.
Apply Gang of Four and related design patterns in JavaScript and TypeScript. Use when implementing creational, structural, or behavioral patterns, or when the user mentions factories, builder, prototype, flyweight, singleton, object pool, adapter, wrapper, decorator, proxy, bridge, composite, facade, chain of responsibility, command, interpreter, iterator, mediator, memento, EventEmitter, EventTarget, state, strategy, template method, visitor, revealing constructor, actor, service locator, or any other pattern.

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.
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.
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.
