go-ecosystem

Use this agent when working with Go code in any capacity - implementing new features, refactoring existing code, reviewing pull requests, debugging issues, or ensuring code quality and security. This includes: - Writing new Go packages, structs, interfaces, or functions - Implementing business logic with clean error handling and concurrency patterns - Creating or updating tests (unit, integration, table-driven) - Running quality checks (gofmt, go vet, staticcheck, golangci-lint) - Performing security audits (gosec, govulncheck) - Synchronizing Go doc comments with documentation in docs/ - Reviewing code for idiomatic Go patterns and adherence to engineering principles - Optimizing goroutine usage and channel communication - Refactoring to improve interface boundaries and dependency injection Examples of when to invoke this agent: <example> Context: User is implementing a new HTTP handler for a REST API endpoint. user: "I need to add a POST /users endpoint that creates a new user in the database" assistant: "I'll use the Task tool to launch the go-craftsperson agent to implement this endpoint following idiomatic Go patterns with proper error handling, context propagation, and comprehensive tests." </example> <example> Context: User has just finished writing a chunk of business logic for processing payments. user: "Here's the payment processor I just wrote:" [code snippet] assistant: "Let me use the go-craftsperson agent to review this code for quality, test coverage, error handling patterns, and ensure it follows the functional core/imperative shell principle. I'll also verify all quality gates pass (gofmt, golangci-lint, tests, gosec)." </example> <example> Context: User is adding concurrency to an existing sequential data processing pipeline. user: "I want to parallelize this data processing loop using goroutines" assistant: "I'm going to use the go-craftsperson agent to refactor this with proper goroutine patterns, channel communication, context.Context for cancellation, and comprehensive tests including race condition checks." </example> <example> Context: Proactive quality check before committing changes. user: "I've made changes to the user service package" assistant: "Before we commit, let me use the go-craftsperson agent to run the full quality gate: gofmt, go vet, staticcheck, golangci-lint, go test with race detection, gosec, govulncheck, and verify docs/ is synchronized with Go doc comments." </example>
