A comprehensive toolkit for building robust, structured logging pipelines in Golang. It provides advanced modules for handler composition (slog-multi), throughput control (slog-sampling), attribute transformation (slog-formatter), and integrates with major backend logging sinks (e.g., Sentry, Loki, Datadog, Elasticsearch). Use this when building complex Go applications that require deterministic log routing, sampling, and data sanitization.

A comprehensive skill for performing deep security audits and writing secure code in Go. It guides developers through identifying vulnerabilities like SQL injection, XSS, path traversal, and crypto misuse. The framework incorporates advanced techniques such as STRIDE/DREAD threat modeling, data flow tracing, and multi-stage review modes (Audit, Review, Coding), ensuring defense in depth for robust Go applications.

A comprehensive guide to tracking the rapidly evolving Go programming ecosystem. It curates official documentation (go.dev, pkg.go.dev), essential newsletters, active communities (r/golang, Slack), influential developers, and top blogs. Use this skill when you need to stay current with Go language updates, discover new libraries, or connect with the development community.

Provides a comprehensive guide to the `stretchr/testify` library for Go testing. It covers essential features like readable assertions (assert/require), mocking dependencies, setting up test suites, and advanced patterns (e.g., JSONEq, Eventually). Use this when writing robust unit tests, ensuring failures are self-explanatory, and managing complex test lifecycles in Go projects.

A comprehensive guide to advanced design patterns in Go, focusing on writing highly testable and clear code. It covers principles like keeping interfaces small and composable, defining contracts where they are consumed, preferring concrete return types, utilizing generics over 'any', and mastering the use of struct embedding and field tags for serialization.

A comprehensive guide for systematically debugging Golang programs. This skill helps users find and fix the root cause of bugs, crashes, deadlocks, race conditions, and performance bottlenecks. It covers advanced techniques like pprof profiling, using Delve, implementing test-driven debugging, and follows a rigorous methodology to ensure deep root cause analysis before proposing any fix. Ideal for production environments and complex concurrency issues.

Comprehensive Go testing guidance that spans table-driven subtests, testify suites, mocking, unit/integration tests, benchmarks, coverage, fuzzing, goleak leak detection, snapshot checks, and GitHub Actions CI to keep production suites reliable.

A comprehensive guide for building scalable and performant GraphQL APIs using Golang. Covers best practices including defining schema (SDL), implementing robust resolver patterns, handling pagination with Relay cursors, and critically, utilizing DataLoaders to prevent N+1 database query issues. Essential for backend engineers designing high-quality services.

This guide details the usage of go.uber.org/dig, a powerful reflection-based container for Dependency Injection in Golang. It covers advanced patterns like using `Provide`/`Invoke` for service registration, grouping parameters with `dig.In`, managing multiple outputs with `dig.Out`, and handling named/grouped dependencies. This is essential for reliably wiring complex application graphs at startup.

A robust application framework for Go that combines a reflection-based Dependency Injection container (built on dig) with advanced features. It provides lifecycle hooks (OnStart/OnStop), a module system, and signal-aware run loops. It is ideal for building complex, long-running services like HTTP servers, daemons, and workers that require structured startup and graceful shutdown.

Google Wire is a robust tool for managing dependency injection in Go. It resolves the application's entire dependency graph at compile time, generating plain, type-safe Go constructor calls. This approach eliminates the need for runtime reflection or heavy dependency containers, ensuring that dependency errors are caught immediately during the build process rather than during application execution. Ideal for building large, scalable, and maintainable Go microservices.

A comprehensive skill for building robust Command Line Interface (CLI) applications in Go using the spf13/cobra library. This skill covers the entire lifecycle of a CLI, including defining command/subcommand trees, managing persistent and local flags, implementing complex argument validators, and utilizing the hook chain (PreRunE, RunE, etc.). It is essential for creating professional, Unix-native command-line tools.
