Skill UI

This skill generates robust, production-grade End-to-End (E2E) and Component tests using the Cypress framework in JavaScript or TypeScript. It supports local execution and cloud testing environments. Use this skill when you need to write Cypress test cases, set up the Cypress environment, or utilize core commands like `cy.get`, `cy.visit`, and `cy.intercept` for functional validation.

This skill helps users deeply understand the root causes of developer attrition, moving beyond basic pricing models. It addresses six key types of churn—including DX issues, integration failures, and market shifts—and provides a framework for calculating a developer health score to identify at-risk users proactively. Ideal for product managers and marketing teams focused on growth and retention.

A comprehensive skill for systematically monitoring developer conversations across technical platforms like GitHub, Reddit, and Stack Overflow. It helps track brand mentions, competitor positioning, and unsolved technical problems to gather unfiltered product feedback and high-intent leads.

This skill provides a comprehensive framework for creating, writing, and optimizing newsletters tailored for developer audiences. It covers content strategy (e.g., 70-20-10 rule), defining newsletter types (curated links, product updates), crafting engaging subject lines, and structuring technical emails for maximum readability and engagement.

This comprehensive guide provides strategies for optimizing the developer onboarding experience. Learn how to get developers to their "first value" (Time-to-First-Value) as quickly as possible using optimized quickstarts, tutorials, and structured sample apps. It covers measuring TTFV, identifying common blockers (like hidden prerequisites), and determining the best mix of interactive vs. static documentation to maximize product adoption rates.

Learn how to transform your technical documentation from a mere resource into a powerful marketing and conversion channel. This skill covers optimizing information architecture, structuring compelling quickstarts, and applying developer-centric principles to attract, convert, and retain developers, enhancing overall product adoption.

EAS Observe is a comprehensive tool for monitoring performance metrics in production Expo applications. It tracks critical performance data, including app startup time, navigation performance across routes, and custom user events. Developers can integrate it into their Expo project using the `expo-observe` package and query detailed reports via the EAS CLI, ensuring optimal user experience and stability.

A portable, framework-agnostic system designed for robust field-side observability in React or React Native apps. It establishes a strongly typed event taxonomy, ensures best-effort, non-blocking data fan-out across multiple analytics providers, and enforces consent gates for all telemetry data. This system complements synthetic testing by capturing real user vitals (LCP, INP, CLS) and behavioral events in production.

This skill guides the structured development process for implementing new features or fixes based on Product Requirement Documents (PRDs) or predefined issues. It emphasizes best practices, including Test-Driven Development (TDD), regular type-checking, running comprehensive test suites, and completing the cycle with a formal review process.

A comprehensive guide and generator for writing robust, production-grade unit and integration tests using JUnit 5 in Java. It covers advanced features like parameterized tests, Mockito mocking, lifecycle management, and nested test structures. Use this skill when you need to write clean, reliable, and highly structured Java test suites.

This skill is designed to identify subtle and complex logic bugs within a single code file or function. It employs a semi-formal execution tracing methodology, systematically breaking down the suspected bug into five stages: Premises (expected state), Trace (execution path), Divergence (actual deviation), Trigger (reproduction case), and Remedy (fix). It is ideal for scenarios where users suspect code is wrong but cannot specify a concrete failure point.

Neon Object Storage provides S3-compatible, branch-aware object storage directly integrated with your Neon Postgres project. It ensures that files (images, documents, user uploads) remain perfectly synchronized with the database schema across all development branches (dev, preview, staging, production). Use this skill when you need a single backend for both database rows and file assets, eliminating the need for separate cloud storage providers.
