Essential command-line tools and system utilities.
Visual UI testing expert using Playwright MCP for browser automation. Use when testing responsive layouts, verifying UI changes, checking breakpoints, debugging visual/CSS issues, or validating component rendering. Triggers on "test UI", "check layout", "verify design", "responsive", "breakpoint", "visual test", "screenshot".
Generate production-ready Playwright E2E tests from natural language specifications or requirements. Creates TypeScript test files following best practices including data-testid locators, proper async/await usage, test isolation, and the AAA (Arrange-Act-Assert) pattern.
Browser automation with Playwright for computer use. Click, type, scroll, screenshot, and execute JavaScript. Use for web testing, automation, and visual verification tasks.
Automatically run relevant tests after code changes
Guide for writing comprehensive tests and achieving >= 95% coverage. Use this when asked to write tests, fix test coverage, or debug failing tests.
This skill should be used when performing browser-based exploratory testing of web applications, including functional testing, visual inspection, accessibility checks, and performance analysis. Triggers when testing web UIs, checking for browser bugs, validating WCAG compliance, or measuring Core Web Vitals.
Use when testing frontend applications. AI-assisted browser testing with Playwright MCP. Fast, deterministic, no vision models needed.
Intelligent unit test generator for frontend projects that detects existing test frameworks and generates comprehensive tests for functions, components, and modules. Use when you need to: (1) Add unit tests to existing codebases, (2) Set up testing infrastructure for new projects, (3) Generate test cases for specific functions or components, (4) Ensure architectural consistency in testing approach across projects. Supports Jest, Vitest, Mocha with React, Vue, Angular frameworks.
JavaScript/Node.js testing best practices with Vitest. Use when writing tests, achieving test coverage, or working with JavaScript/TypeScript test files.
Playwright automation best practices for web scraping and testing. Use when writing or reviewing Playwright code, especially for element operations (click, fill, select), waiting strategies (waitForSelector, waitForURL, waitForLoadState), navigation patterns, and locator usage. Apply when encountering unstable tests, race conditions, or needing guidance on avoiding deprecated patterns like waitForNavigation or networkidle.
Create formal spec-driven MoonBit APIs and test suites. Use when asked to set up a spec.mbt, spec-driven tests, or a formal contract-first workflow (e.g., "set up a formal spec & test suite for Yaml in MoonBit"), including moon.mod.json/moon.pkg.json scaffolding and guidance to implement in separate files.
Web application testing toolkit using Playwright with Python. Use for verifying frontend functionality, debugging UI behavior, capturing browser screenshots, viewing browser logs, and automating web interactions.
Chrome DevTools for debugging, performance analysis, and browser automation. Use when debugging web apps, analyzing performance, inspecting network requests, or automating browser interactions.
Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
Create comprehensive test suites by discovering and adapting to any testing framework, following project test patterns and ensuring robust coverage. Use when writing tests, improving coverage, validating functionality. Triggers: 'test', 'coverage', 'unit test', 'integration test', 'E2E', 'spec', '테스트', '커버리지', '단위 테스트', '통합 테스트', '테스트 작성', working with *.test.*, *.spec.*, test/, __tests__/.
General-purpose browser automation skill for Playwright. Use this skill when the user wants to automate browser tasks like testing login flows, scraping data, taking screenshots, filling forms, clicking elements, or any interactive web automation. This skill provides smart utilities for session management, error handling, and development server detection. NOT for scheduled monitoring (use web-monitor-bot instead).
Automate browser interactions with Playwright MCP. Use for web scraping, form filling, testing, or any browser-based automation tasks.
Debug failing Playwright E2E tests by analyzing error messages, stack traces, screenshots, and Playwright traces. Provides actionable solutions for common test failures including timeouts, selector issues, race conditions, and unexpected behaviors. Optionally uses Playwright MCP for live debugging.
通过理解文件内容与使用场景的上下文，智能地在你的电脑中整理文件和文件夹：查找重复文件、建议更合理的目录结构，并自动执行清理任务。在无需手动费力整理的情况下，降低认知负担，让你的数字工作空间保持整洁有序。当准备归档旧项目、希望自动清理与重建目录结构时，使用该技能。
Perform safe code refactoring with reference checking and validation. Uses Julie's rename_symbol for workspace-wide renames and fuzzy_replace for precise edits. Activates when user wants to refactor, rename, or safely modify code.
Manage likec4.config.json includes and image aliases. Ensures relative paths and preserves existing configuration.
Use when adding features or fixing bugs. Follow RED/GREEN/REFACTOR cycle. Write failing test first, implement minimal code to pass, then refactor.
コードをリファクタリングするスキル。 以下の状況で使用: (1) ユーザーが「このコードをリファクタリングして」と依頼した時 (2) ユーザーが明示的に「/code-refactor」を実行した時 (3) コードの改善・整理を求められた時
