This skill provides comprehensive guidelines for structured concurrency in Go. It covers best practices for managing goroutine lifecycles, preventing leaks, and choosing between channels, mutexes, and atomic operations. It details patterns like fan-out/fan-in, error handling with `errgroup`, and deduplication with `singleflight`, ensuring correct and leak-free concurrent code.

A comprehensive guide to best practices for using context.Context in Go. Learn how to correctly propagate cancellation signals, handle timeouts and deadlines, and manage request-scoped values across API boundaries, ensuring robust and efficient concurrent application design.

A comprehensive guide for setting up production-grade CI/CD pipelines for Go projects using GitHub Actions. It covers all critical stages: unit testing (with race detection), linting, static application security testing (SAST), vulnerability scanning, automated dependency updates (Dependabot/Renovate), Docker image builds, and automated releases via GoReleaser. Ideal for DevOps engineers establishing or improving Go project quality gates.

This comprehensive guide dives deep into the internals of Go's built-in data structures (slices, maps, arrays) and standard library packages. It covers critical topics like capacity growth mechanics, preallocation strategies, pointer types (unsafe/weak), and the optimized usage of specialized containers (heap, list, ring). Use this resource to select the correct structure for optimal performance and memory safety in expert Go development.

A comprehensive guide for writing safe, explicit, and observable database code in Go. It covers best practices for using standard libraries like `database/sql`, `sqlx`, and `pgx`. Key topics include parameterized queries, context propagation, transaction management, connection pooling, and ensuring data integrity while avoiding common pitfalls like ORMs and SQL injection.

Provides a comprehensive guide to Dependency Injection (DI) in Go. It covers the principles of loose coupling, testability, and separation of concerns, contrasting manual constructor injection with popular DI libraries (Wire, Dig, FX). Ideal for designing service architectures, refactoring coupled code, or understanding the principles of Inversion of Control in Go applications.

A comprehensive guide to best practices for managing dependencies in Go projects. It covers the use of go.mod, go.sum, and essential commands like go mod tidy and govulncheck to ensure secure, stable, and reproducible builds. Use this skill when adding, upgrading, removing, or auditing external Go modules to maintain project integrity.

This skill provides comprehensive guidance on idiomatic Go patterns for building production-ready, robust applications. It covers best practices like functional options, proper constructor design, resource management (timeouts, graceful shutdown), error handling, concurrency patterns, and architectural styles (DDD, Hexagonal). Use it when structuring complex Go APIs, defining service boundaries, or auditing existing code for common anti-patterns and performance pitfalls.

A comprehensive guide and skill for generating and auditing high-quality technical documentation for Go projects. It covers writing accurate godoc comments, READMEs, CONTRIBUTING, and CHANGELOGs for both libraries and CLIs, adhering to professional best practices. Supports multi-agent orchestration for large-scale codebases.

This skill provides comprehensive guidelines for writing idiomatic, robust, and production-ready error handling in Go. It covers best practices for error creation, proper wrapping using `%w`, inspection techniques with `errors.Is` and `errors.As`, adhering to the single handling rule, and utilizing structured logging with `slog`. Use it when auditing, reviewing, or writing new Go code to ensure reliable error propagation and logging.

A comprehensive guide for designing, implementing, and reviewing scalable microservices using gRPC in Go. It covers critical best practices including structured protobuf organization, implementing interceptors for cross-cutting concerns, managing connection deadlines, handling standardized gRPC status codes, and ensuring graceful shutdown for robust distributed systems.

A comprehensive guide to achieving high code quality in Go projects using `golangci-lint`. This skill covers the entire development lifecycle, including setting up the essential `.golangci.yml` configuration, running automated linters (style, security, complexity), automatically fixing issues, interpreting detailed lint output, and correctly suppressing false positives using `//nolint` directives. Ideal for enforcing best practices in CI/CD pipelines and maintaining legacy codebases.
