Skill UI

This skill provides comprehensive guidelines for Go language naming conventions. It covers best practices for packages, structs, constants, constructors, errors, and more. Use it when writing new Go code, refactoring existing code, or debating proper naming styles (e.g., MixedCaps vs snake_case) to ensure adherence to Go's idiomatic style.

Guides Go engineers through production observability by covering structured logging with slog, Prometheus metrics, OpenTelemetry tracing, continuous profiling, RUM event tracking, alerting, and Grafana dashboards for observable services.

This skill acts as a Go ecosystem expert, providing recommendations for production-ready libraries and frameworks. It guides developers through selecting the simplest, most performant, and idiomatic Go solution, prioritizing the standard library first and only suggesting external dependencies when they provide clear, necessary value.

This comprehensive guide provides best practices for structuring and initializing Golang projects. It covers standard layouts for various project types (CLI tools, microservices, libraries, monorepos), adhering to 12-Factor App principles, and mastering Go module naming conventions. Use this resource when starting a new Go project or refactoring an existing codebase to ensure scalability, maintainability, and architectural soundness.

This skill teaches defensive programming techniques for Go, aiming to prevent common runtime bugs, panics, and silent data corruption. It covers critical topics such as nil safety (interfaces, maps, slices), handling slice aliasing via append, numeric overflow prevention, and correct resource management using defer.

Guides Go developers through samber/do v2 usage for setting up dependency injection containers, registering providers, invoking services, managing lifecycles, and organizing scoped modules during refactors or service orchestration.

Guides Go engineers on using samber/hot for in-memory caches with TTL, loader chains, sharding, and metrics, plus choosing eviction algorithms to fit work-set and stability needs.

Provides samber/lo helpers for Go developers to write declarative, type-safe collection transforms, covering Map, Filter, Reduce, GroupBy, chunking, and parallel/mutable/iterator variants with zero dependencies when the stdlib falls short.

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.

Build declarative reactive streams in Go with samber/ro, leveraging 150+ type-safe operators, cold/hot observables, subjects, rich plugins, automatic backpressure, and context-aware error propagation for real-time and asynchronous pipelines.

A comprehensive guide and set of tools for performing deep security audits and implementing secure coding practices in Golang. It covers threat modeling (STRIDE), data flow tracing, input validation, cryptography, secrets management, and vulnerability prevention for critical areas like SQL injection and authentication.

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.
