This guide provides essential best practices for building reliable, fault-tolerant applications in Go using DBOS durable workflows. It covers architectural patterns for integrating DBOS into existing Go code, defining complex workflows, managing steps, and utilizing queues for robust concurrency control. Essential reading for developers setting up, configuring, or testing mission-critical asynchronous processes.

Curated guidelines covering idiomatic Go error handling, interface design, concurrency patterns, context propagation, testing, and module management for reliable team codebases.

Collection of Go idioms and best practices for building robust, maintainable services, covering simplicity, zero values, interface returns, error handling, and concurrency when writing, reviewing, or refactoring Go code.

This skill simulates a senior Go developer, specializing in writing high-performance, production-grade Go applications. It covers advanced topics like concurrent programming using goroutines and channels, designing robust microservices with gRPC/REST, and optimizing code using pprof and benchmarks. It enforces idiomatic Go patterns, context propagation, and strict testing practices (table-driven, fuzzing, race detection).

Documented Go testing workflow covering TDD, table-driven cases, subtests, helpers, mocking, and HTTP handler verification so teams can ensure robust unit and integration coverage for their Go services.

A comprehensive guide for designing and implementing production-grade microservices using gRPC in Go. Covers best practices for API contract standardization with Protobuf and Buf, securing service-to-service communication via mTLS, and integrating deep observability using OpenTelemetry interceptors. Ideal for building high-performance, reliable internal APIs.

Expert guide for building durable distributed systems with the Temporal Go SDK, covering deterministic workflow rules, mTLS worker configuration, advanced patterns, and testing/observability strategies for production workloads.

Scans Go codebases for security vulnerabilities, highlighting risky patterns, insecure dependencies, and misconfigurations so auditors can catch issues before deployment.

This skill provides a comprehensive framework for measuring Go application performance. It guides users through writing robust benchmarks using `testing.B`, running tests with various flags (`-benchmem`, `-cpuprofile`), interpreting complex profiling data (pprof), statistically comparing results using tools like `benchstat`, and setting up CI regression detection. It is essential for deep performance analysis and making statistically sound optimization decisions.

A comprehensive guide for developing robust, Unix-native Command Line Interfaces (CLIs) using Go. It details best practices for command structure, flag handling, configuration layering (Viper), and argument validation using Cobra. Learn how to build, extend, and review professional-grade Go tools that behave predictably in shell environments.

Guidelines for writing clear, idiomatic Go code: line breaking, variable declarations, composite literals, control flow, and function design. Useful when reviewing Go code or setting project coding standards.

A comprehensive guide for writing, reviewing, and auditing concurrent Go code. It covers core principles of structured concurrency, including proper resource management for goroutines, safe use of channels, mutexes, and advanced synchronization primitives like errgroup and singleflight. Essential for avoiding common issues like goroutine leaks, race conditions, and context propagation failures.
