A comprehensive guide on utilizing Firebase Remote Config within Flutter applications. Learn how to implement dynamic feature flags, execute A/B testing, manage remote parameter defaults, and fetch real-time configuration values. This skill allows developers to modify app behavior and user experiences without requiring an app store update, ensuring fast iteration and efficient product testing.

Guides integrating Firebase Cloud Storage with Flutter apps, covering setup, uploads/downloads, metadata, error handling, and security best practices for file management workflows.

A comprehensive guide to structuring robust Flutter applications using industry-standard layered architecture (UI, Domain, Data). It details patterns like MVVM, Repository pattern, and Use Cases, ensuring clean separation of concerns, manageable state flow (unidirectional data flow), and testability. Ideal for scaffolding new, large-scale projects or refactoring legacy codebases.

A comprehensive guide to disciplined version control using Git. It outlines best practices for atomic commits, descriptive message formatting (feat, fix, refactor), adopting trunk-based development, and managing feature branches. Use this whenever making code changes, committing, or coordinating complex work streams to ensure code stability and traceability.

Guides multi-round investigation of any GitHub repository, combining API queries, discovery searches, and deep dives to produce structured markdown reports with summaries, timelines, metrics tables, and Mermaid diagrams for executive-ready briefs.

Accelerates GitHub cloning, release/raw/archive downloads, and other resource access for Mainland China users by rewriting URLs through githubproxy.cc or fallback ghfast.top, with an optional URL converter script for quick adaptation.

Provides a comprehensive guide to implementing Dependency Injection (DI) in Golang. It covers the principles of loose coupling, testability, and separation of concerns, detailing methods from manual constructor injection to using popular libraries like google/wire and uber-go/dig. Essential for structuring scalable, maintainable, and robust Go services.

This skill provides comprehensive guidance on idiomatic Go design patterns and best practices for writing production-ready code. It covers functional options, constructor design, graceful shutdown, resource management, dependency injection, and crucial architectural considerations, helping developers write robust and maintainable Go applications.

This comprehensive guide covers best practices for building robust, production-ready gRPC microservices in Go. It details proper protobuf organization, utilizing interceptors for cross-cutting concerns (logging, auth), implementing graceful shutdowns, handling gRPC status codes, and optimizing client connections with deadlines and retry policies. Essential for engineers designing reliable distributed systems.

A comprehensive guide detailing recommended naming conventions for various Go language elements, including packages, structs, interfaces, constants, functions, and error handling. Use this skill when writing, reviewing, or refactoring Go code to ensure adherence to idiomatic Go style.

This skill provides comprehensive observability tooling for Go services, covering the five essential signals: structured logging (slog), Prometheus metrics, OpenTelemetry tracing, continuous profiling, and RUM. Use it for proactive production monitoring, correlating logs with traces, setting up SLOs, and ensuring all new features are fully instrumented for robust diagnosis.

This guide serves as a comprehensive blueprint for architecting and structuring Golang projects. It covers best practices for defining project types (CLI, Service, Library, Monorepo), adhering to 12-Factor App principles, standardizing module naming conventions, and establishing optimal directory layouts (cmd/, internal/, pkg/). Use it when starting a new Go application or refactoring a complex codebase to ensure maintainability and scalability.
