Implement n8n credential types including API key, OAuth2, and header-based authentication patterns. Use this skill when creating *.credentials.ts files, implementing ICredentialType interfaces, configuring OAuth2 flows, setting up credential testing, injecting authentication headers, or following credential security best practices. Apply when building any n8n node that requires API authentication, token management, or secure credential handling.
Railway authentication and token management. Use when logging into Railway, creating API tokens, setting up CI/CD authentication, or verifying Railway credentials.
Documentation Guardian. Detects stale docs and enforces update rules.
Manage device adoption and onboarding, maintain device inventory, and monitor device configurations across your UniFi Protect infrastructure.
Automates Langfuse Cloud dashboard interactions using Playwright MCP. Captures screenshots for documentation, extracts metrics for monitoring, navigates trace details for investigation, and handles authentication. Use when documenting workflows, creating compliance screenshots, monitoring dashboard metrics, or investigating traces visually. MUST use Playwright MCP tools (mcp__playwright__*) for browser automation.
Mobile device emulation and responsive testing with Playwright. Use when testing mobile layouts, touch interactions, device-specific features, or responsive breakpoints.
Browser automation via Playwright MCP. Use for verification, browsing, web scraping, testing, screenshots, and all browser interactions.
Generate Vitest configuration files for fast unit testing of JavaScript/TypeScript projects. Triggers on "create vitest config", "generate vitest configuration", "vitest setup", "unit test config".
Performance testing using Chrome DevTools, Lighthouse, and Core Web Vitals monitoring. Use for performance profiling or optimization validation.
Interactive browser automation via Chrome DevTools Protocol. Use when you need to interact with web pages, test frontends, or when user interaction with a visible browser is required.
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.
Increase test coverage from 0% to 80%+ in ANY project, ANY testing framework
Browser automation for visual testing, accessibility audits, and DOM inspection using Playwright. Use this skill when users need to: (1) Run accessibility (a11y) audits on websites and generate reports, (2) Take screenshots of web pages (full-page or elements), (3) Compare screenshots to detect visual changes, (4) Inspect or select DOM elements interactively to get context for modifications, (5) Connect to an existing browser session or navigate to URLs for testing. Triggers on: "a11y audit", "accessibility check", "screenshot", "visual diff", "compare screenshots", "element picker", "inspect element", "DOM context", "what's on this page", "browser automation".
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.
Chrome DevTools QA workflow for the Sketch Magic kid-first UI. Use when validating Console/Network/Performance, investigating “tap doesn’t work”, /api/convert failures, mobile touch issues, or when a proof video must be backed by DevTools evidence.
