Comprehensive guide for creating, reviewing, and improving skills that extend Claude's capabilities with specialized knowledge, workflows, and tool integrations. Use this skill when: (1) Creating a new skill from scratch, (2) Reviewing or auditing an existing skill for quality and adherence to best practices, (3) Updating or refactoring an existing skill, (4) Understanding skill architecture, anatomy, and design patterns, (5) Troubleshooting skill loading, triggering, or packaging issues, (6) Learning how to effectively use bundled resources like scripts, references, and assets, (7) Planning what type of skill structure is appropriate for a given use case.

Agent creation guidelines and protocols for eliminating ambiguity while preserving flexibility. Provides agent architecture patterns, security guardrails, permission tiers, and orchestration patterns. Includes agent archetypes and integration guidelines. Scope: agent creation, agent structure, security patterns, orchestration. Excludes: skill creation, command creation (handled by component-specific skills). Triggers: agent, create agent, orchestrate, new agent.

Utility scripts for GitHub pull request management. Includes tools for fetching bot-generated review comments (linters, security scanners, dependabot), replying to review threads programmatically, listing merged pull requests with filtering, resolving conversations, and automating PR review workflows. Useful for batch processing comments, CI/CD integration, quality metrics tracking, release notes generation, and automated responses to bot reviewers.

Execute complex browser automation using Playwright Python. Use for video recording, multi-page navigation, data extraction. Triggers on "browser script", "record video of website", "extract data from webpage".

Build reliable third-party API integrations including OAuth, webhooks, rate limiting, error handling, and data sync. Use when integrating with external services (Slack, Stripe, Gmail, etc.), building API connections, handling webhooks, or implementing OAuth flows.

Builds end-to-end browser tests for critical user flows using Playwright or Cypress. Includes selector strategies, test data management, page objects, and visual regression testing. Use for "E2E testing", "browser tests", "Playwright", or "Cypress tests".

Write E2E tests with Playwright including Page Object Model, visual regression testing, and CI/CD integration. Use when testing user flows, integration testing, or visual regression testing.

Generate optimized images for Marp slides using Playwright MCP with theme-matching color palettes and guideline-compliant sizes

Integrate coverport into Go repositories with Tekton pipelines to enable e2e test coverage collection and upload to Codecov. Use this skill when users ask to integrate coverport, add e2e coverage tracking, or set up coverage instrumentation for Go projects.

This skill enables Claude to generate end-to-end (E2E) tests for web applications. It leverages Playwright, Cypress, or Selenium to automate browser interactions and validate user workflows. Use this skill when the user requests to "create E2E tests", "generate end-to-end tests", or asks for help with "browser-based testing". The skill is particularly useful for testing user registration, login flows, shopping cart functionality, and other multi-step processes within a web application. It supports cross-browser testing and can be used to verify the responsiveness of web applications on different devices.

Systematic code review with security, performance, and architecture analysis. Provides actionable fix suggestions and GitHub PR integration. Use when reviewing PRs, validating code changes, or checking code quality.

Integrate OpenAI ChatKit framework with custom backend and AI agents. Handles ChatKit server implementation, React component integration, context injection, and conversation persistence.

Playwright E2E 테스트 실행. Use when (1) "E2E 테스트", "런타임 테스트",(2) 구현 완료 후 브라우저 검증, (3) PR 전 통합 테스트.

Comprehensive E2E testing skill using Playwright MCP for systematic web application testing. This skill should be used when users need to test web-based systems end-to-end, set up test regimes, run exploratory tests, or analyze test history. Triggers on requests like "test my webapp", "set up E2E tests", "run the tests", "what's been flaky", or when validating web application functionality. The skill observes and reports only - it never fixes issues. Supports three modes - setup (create test regime), run (execute tests), and report (analyze results).

Use when implementing critical user workflows that span multiple pages/components - tests complete journeys end-to-end using Page Object Model, user-centric selectors, and condition-based waiting; use sparingly (10-15% of tests)

Playwright end-to-end testing for ScreenGraph using .env-driven configuration. Use when validating full user flows, running regression suites, or inspecting UI behavior with Cursor browser tools.

AI-powered testability assessment using 10 principles of intrinsic testability with Playwright and optional Vibium integration. Evaluates web applications against Observability, Controllability, Algorithmic Simplicity, Transparency, Stability, Explainability, Unbugginess, Smallness, Decomposability, and Similarity. Use when assessing software testability, evaluating test readiness, identifying testability improvements, or generating testability reports.
