Skill UI

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.

Guides building production-ready user interfaces with thoughtful component architecture, consistent spacing, typography, color, and accessibility standards while avoiding generic AI aesthetics and over-configured patterns.

Enforces full, unabridged code and document generation by overriding LLM truncation safeguards, forbidding placeholder patterns, and managing token-limit splits so every requested deliverable is returned complete.

Guidance for building, extending, and reviewing production Go CLIs with Cobra+Viper: project layout, root command defaults, flag binding, validation, config layering, logging, and completion patterns for Unix-friendly tooling.

Explains Go slice/map/array/container internals, allocation patterns, generic collections, and safety guidance so engineers can pick or tune the right data structure for performance-critical code.

A comprehensive guide and utility for applying idiomatic Go patterns, serving as an architectural guide for building robust, production-ready Go applications. It covers best practices for functional options, graceful shutdown, error flow management, resource cleanup, concurrency, and dependency injection, helping developers avoid common pitfalls like using `init()` or unbounded resources. Ideal for code reviews and initial system design.

Guides Go distributed-system engineers through protobuf layout, interceptor design, error handling, TLS/mTLS setup, bufconn testing, and streaming RPC patterns so they can implement, review, and debug real-world gRPC servers and clients with production-grade operability.

This skill simulates a Go modernization engineer, continuously updating Go codebases to comply with the latest language features, standard library improvements, and idiomatic patterns. It scans for deprecated APIs, outdated Go patterns, and suggests best practice refactorings (e.g., using `slog`, advanced testing patterns). Use it during code review, large-scale refactoring, or when upgrading Go versions to ensure high code quality and maintainability.

Golang performance optimization patterns and methodology; applies when profiling or benchmarks highlight a bottleneck and you need targeted solutions for allocations, CPU, GC tuning, caching, pooling, or hot-path code reviews.

Monadic types from samber/mo provide Go projects with Option, Result, Either, Future, IO, Task, and State abstractions to keep nulls safe, errors composable, and side effects predictable whenever you adopt functional patterns or import github.com/samber/mo.

Guides Go developers through struct/interface design best practices, covering interface segregation, composition, dependency injection, type assertions, and choosing pointer vs value receivers to keep APIs clear and testable.

Provides shared GWS CLI behaviors for authentication, global flags, formatting, pagination, and safety patterns, plus zsh tips and community guidance for safely scripting workspace workloads.
