單元測試

Use when adding Jest testing configuration to Nx projects, running `nx g @nx/jest:configuration`, setting up testing infrastructure, or troubleshooting tests that fail after running the Jest generator. Ensures proper TypeScript moduleResolution (nodenext), testing enhancement libraries (jest-dom, user-event, MSW), and monorepo pattern adherence. Triggers: "add tests", "setup Jest", "configure testing", "Jest not working", "moduleResolution error", "tests failing after generator"

Docker 환경에서 Playwright E2E 테스트 실행. 브라우저 미종료 문제 해결, 스크린샷, 로그 캡처 지원.

Optimize CTA copy, hero sections, and button text for higher conversions using therapy-appropriate frameworks (PAS, AIDA, BAB). Maintains empathetic, non-salesy tone while driving action. Creates A/B test variations, scores conversion potential, and ensures CRPO compliance. Use when user mentions "CTA", "conversion rate", "improve button text", "more bookings", or asks about improving page performance.

Validates tests for test theater anti-patterns. Use when reviewing test code, writing new tests, or when user asks to check tests for quality issues. Ensures tests verify real behavior, not just provide false confidence.

Use this skill when writing or updating SQL queries (query.sql) or Python ETL scripts (query.py) following Mozilla BigQuery ETL conventions. ALWAYS checks for and updates existing tests when modifying queries. Coordinates downstream updates to schemas and tests. Works with bigquery-etl-core, metadata-manager, and sql-test-generator skills.

Enumerate and exploit network services including SMB, FTP, SSH, RDP, HTTP, databases (MySQL, MSSQL, PostgreSQL, MongoDB), LDAP, NFS, DNS, and SNMP. Use when testing network service security or performing port-based exploitation.

Generate real Cassandra 5.0 test data using Docker containers, export SSTables with proper directory structure, validate parsing against sstabledump, and manage test datasets. Use when working with test data generation, dataset creation, SSTable export, validation, fixture management, or sstabledump comparison.

Run all tests for the Gambit game engine. Use when the user wants to run tests, verify functionality, or check that code changes haven't broken anything.

指定されたコンポーネントの全テスト（unit, a11y, vrt, interaction）を実行し、結果をレポートする。

Proactively diagnose and fix code bugs. Use when errors occur, tests fail, or performance issues arise. Analyzes stack traces, identifies root causes, and provides working fixes.

Use when tests have race conditions, timing dependencies, or inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes, eliminating flaky tests from timing guesses

Expert TypeScript/JavaScript development guidance. Use when planning or writing TypeScript/JavaScript code, setting up TS/JS projects, configuring build tools (pnpm, Vite, TypeScript), implementing tests (Vitest), adding logging (pino for services, chalk/console for CLIs), working with React/Tailwind/Xstate, or following FP patterns. Covers stack decisions, tooling setup, testing strategies, and logging patterns for both services and CLI tools.

Reads Vintage Story logs after manual testing by the user.

Build, run, test, and debug Apple platform apps (iOS, macOS) headlessly using xcede CLI. Use when working with Xcode projects or Swift packages outside of Xcode IDE. Covers building for devices/simulators/Mac, running apps, executing tests (XCTest/Swift Testing), debugging with lldb, and configuring projects via .xcrc files.

Testing methodologies, patterns, and best practices for unit, integration, and E2E tests. (project)

Test-Driven Development workflow. Use when implementing new features with tests first. Activated by "TDD", "test first", "write tests".

Use when writing or changing tests, adding mocks, or tempted to add test-only methods to production code - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

Debug Neovim/LazyVim configuration issues. Use when: user reports Neovim errors, keymaps not working, plugins failing, or config problems. Provides systematic diagnosis through hypothesis testing, not just checklists. Think like a detective narrowing down possibilities.

Integrate new DEX aggregators, swappers, or bridge protocols (like Bebop, Portals, Jupiter, 0x, 1inch, etc.) into ShapeShift Web. Activates when user wants to add, integrate, or implement support for a new swapper. Guides through research, implementation, and testing following established patterns. (project)

Evaluate and improve Claude skills for clarity, completeness, testability, and architectural coherence.
