Skill UI

An expert tool for generating high-level system context documentation using the C4 Model. This skill helps define system boundaries by documenting key personas, user journeys, core features, and external dependencies. It provides a stakeholder-friendly overview, ideal for initial architectural planning and system scoping.

This comprehensive guide demonstrates the essential workflow for integrating with Customer.io using its SDK. It covers the core functions required for user lifecycle management: identifying and updating user profiles, tracking custom events (both authenticated and anonymous), and sending transactional emails. Ideal for developers performing quick customer journey mapping or initial platform setup.

This skill provides comprehensive guidance on building reliable, fast, and maintainable end-to-end (E2E) test suites. It ensures code quality by validating critical user journeys and catching regressions in complex workflows before deployment. Essential for setting up robust CI/CD pipelines, cross-browser compatibility, and establishing rigorous QA standards.

A comprehensive guide to production-ready error tracking using Sentry SDK in TypeScript and Python. Learn how to implement structured error context via scopes, manage user journeys with breadcrumbs, filter out noise and PII using beforeSend/beforeBreadcrumb hooks, and use custom fingerprinting for accurate issue grouping. Essential for robust observability.

Generates structured CodeTour `.tour` files in JSON format for detailed, step-by-step code walkthroughs. This tool is essential for onboarding new engineers, conducting architectural reviews, or documenting complex PR changes. It provides a guided narrative that directs users to specific files and line anchors, ensuring a structured and focused learning journey.

Master the art of creating, maintaining, and running robust end-to-end (E2E) tests for Flutter applications using the Patrol framework. This skill covers validating complex user journeys, testing interactions with native system features (like permissions and deep links), capturing UI regressions, and ensuring consistent cross-platform behavior across Android, iOS, and Web. Best practice guidelines for deterministic testing are included.

Generate a high-fidelity, multi-screen mobile prototype simulating a gamified experience, perfect for habit trackers, life management apps, or RPG concepts. The output features three distinct phone frames: cover/value proposition, daily quests dashboard, and detailed quest view, all presented on a single dark showcase stage. Ideal for visualizing user journeys and engagement mechanics.

This skill generates a comprehensive, actionable performance budget document for any web service or application. It moves beyond wish lists by establishing measurable performance constraints, covering key user journeys, Core Web Vitals (LCP, CLS, INP), backend SLOs (P95, P99), and architectural limitations. It guides teams on setting targets, measurement tools, and incident response processes when budgets are breached.

This skill automates end-to-end (E2E) functional testing for Android applications. It parses an XML specification defining a multi-step user 'journey.' The executor sequentially performs interactive UI actions (taps, swipes, text input) using ADB commands and verifies application states through assertions. It outputs a detailed, standardized JSON report, making it ideal for robust CI/CD integration and quality assurance.
