Comprehensive Go engineering guidelines for writing production-quality Go code. This skill should be used when writing Go code, performing Go code reviews, working with Go tools (gopls, golangci-lint, gofmt), or answering questions about Go best practices and patterns. Applies to all Go programming tasks including implementation, refactoring, testing, and debugging.
Use when Go error handling with error wrapping, sentinel errors, and custom error types. Use when handling errors in Go applications.
Use the Functional Option Pattern for configurable Go constructors. Applies to types needing multiple optional parameters with validation and defaults. Includes Go 1.25 generics support.
Core Go programming concepts - syntax, types, interfaces, error handling
Expertise in Go programming according to the Google Go Best Practices. Focuses on actionable advice for naming, error handling, performance, testing, and general idiomatic Go to ensure high-quality, maintainable, and efficient codebases.
Expertise in Go programming decisions according to the Google Go Style Guide. Focuses on specific choices for naming, error handling, and language usage.
You are an expert Go developer committed to the Google Go Style Guide. Your goal is to produce code that is readable, maintainable, and idiomatic.
Use this skill to plan, write, or run database migrations with the pressly/goose CLI and Go library (SQL/Go migrations, env vars, provider API, embedded migrations).
Build gRPC services with Go - protobuf, streaming, interceptors
Use when Go interfaces including interface design, duck typing, and composition patterns. Use when designing Go APIs and abstractions.
Kubernetes operators and client-go development
Run local Go health checks (tests, coverage, lint) in Go repositories that contain go.mod/go.sum. Use when the user asks to run or interpret local Go test/coverage/lint workflows using tools like lazygotest, gocovsh, tparse, and golangci-lint. Do not use for Rust or non-Go projects.
Go module system, dependency management, and project configuration assistance.
Go modules and dependency management

Expert in generating functional options for Go structs using the options-gen library.
Go performance optimization - profiling, benchmarks, memory management
Expert Go developer specializing in idiomatic patterns, concurrency, error handling, and clean package design. This skill should be used PROACTIVELY when working on any Go code - implementing features, designing APIs, debugging issues, or reviewing code quality. Use unless a more specific subagent role applies.
Use when writing Go code to interact with Hetzner Cloud API - automation, infrastructure provisioning, bots, integrations, or programmatic cloud operations
Security audit for Go backend code and SDKs. Covers Go-specific vulnerabilities, common security pitfalls, and best practices. Use when auditing Go codebases.
Expert senior-level Go guidance for architecture, API-first design/codegen, advanced concurrency, performance tuning, testing/quality, cloud-native 12-factor practices, and Go 1.24+ tooling for large-scale systems.
Define, review, and scaffold Go service directory structures using hexagonal (ports-and-adapters / “jexagonal”) architecture and Go best practices. Use when creating or refactoring Go services, deciding package boundaries, organizing cmd/internal/api/config/deploy/migrations, or choosing layouts for common service types (HTTP REST API, gRPC API, async worker/consumer, scheduled job, CLI, multi-binary repos).
Shared Go best practices for LlamaFarm CLI. Covers idiomatic patterns, error handling, and testing.
Go language consultant providing guidance on best practices, testing with testify, concurrency patterns, error handling, and technology stack recommendations. Use when answering Go questions, reviewing Go code, or advising on Go implementation approaches.
Review Go code against comprehensive style guide, focusing on critical bugs and important maintainability issues.
go-test
Write and run Go tests using the built-in testing package with table-driven tests, subtests, and mocking via interfaces. Use when writing Go tests or setting up test infrastructure.
Handles all Golang testing tasks including running tests, writing new tests, and fixing test failures. Follows MCPSpy testing conventions with require for critical assertions and assert for non-critical ones.
Plan product launches and go-to-market strategy. Use when launching products, entering new markets, or planning marketing campaigns. Covers positioning, channels, messaging, and launch execution.
Master product launches, positioning, messaging, and GTM strategies. Use when planning launches, entering markets, or positioning products.
Use this skill to write, refactor, or review Go code according to the Uber Go Style Guide. It ensures strict adherence to correctness, safety, and idiomatic patterns.
Use this skill when writing Go code following the Uber Go Style Guide. Provides comprehensive guidance on idiomatic Go patterns, error handling, concurrency safety, performance optimization, and test-driven development. Covers all critical Uber Go rules including channel sizing, goroutine management, interface design, and proper error handling. Appropriate for any task involving .go files, Go code reviews, refactoring, or implementing Go best practices.
