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 provides best practices for creating, reviewing, and auditing documentation for Go projects. It covers writing principles (e.g., Intent over paraphrase, Concision), structuring documentation (godoc comments, README, CHANGELOG), and workflow orchestration for both libraries and CLI applications. Ideal for technical writers and developers ensuring code is discoverable and maintainable.

A comprehensive guide and toolset for Go code quality assurance using `golangci-lint`. It enables developers to run multiple linters in parallel, configure best practices via `.golangci.yml`, automate fixes, and interpret complex lint output. Ideal for maintaining code standards, setting up CI/CD pipelines, and cleaning up legacy codebases.

This skill automatically modernizes Go codebases by identifying and replacing outdated patterns, deprecated APIs, and non-idiomatic code. It conducts comprehensive scans across language features, standard library upgrades, testing patterns, and tooling (including running lint checks). It ensures the codebase adheres to the latest Go best practices, improving safety, correctness, and readability for modern Go versions.

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.

A comprehensive guide for optimizing Golang applications, covering systematic approaches to identifying and resolving bottlenecks. It details best practices for reducing memory allocations, improving CPU efficiency, tuning GC, and managing concurrency. The methodology emphasizes profiling first (using pprof, fgprof) and following an iterative cycle: Benchmark → Diagnose → Improve → Benchmark.

This skill acts as an expert guide to the Go ecosystem, helping developers select production-ready libraries and frameworks. It emphasizes prioritizing the standard library, assessing library maturity, and ensuring the simplest, most performant choice for any given Go project.

A comprehensive guide for setting up robust and scalable Go projects. It covers best practices for directory structure (cmd, internal, pkg), module naming conventions, adopting 12-Factor App standards, and choosing appropriate architectural patterns (Clean, Hexagonal, DDD). Ideal for starting new services, libraries, or monorepos in Go.

Defensive Golang guidance for avoiding panics, nil traps, append aliasing, overflow, float comparison bugs, and resource leaks. Useful for writing safer code and reviewing runtime risks.

A type-safe dependency injection toolkit specifically designed for Go. It provides a robust service container for managing application dependencies, supporting various service lifecycles (Lazy, Eager, Transient, Value). This tool helps developers establish clean composition roots, manage complex service relationships, and organize large-scale Go projects following best architectural practices.

A comprehensive, type-safe in-memory caching library for Go, designed for advanced system architecture. It supports nine sophisticated eviction algorithms (like W-TinyLFU, LRU, LFU, ARC) to optimize cache hit rates based on specific access patterns. Key features include TTL management, loader chains for read-through caching (with singleflight deduplication), sharding, and Prometheus metrics. Ideal for high-frequency services needing to reduce database load and latency.
