description	Build and review Go services, CLIs, and infrastructure tools. Use for HTTP/gRPC APIs, concurrency, context cancellation, database access, observability, and deployment.

Go Service Development

Purpose

Help engineers write idiomatic, reliable Go with explicit error handling, predictable concurrency, and simple operational behavior.

Workflow

1. Inspect module layout, Go version, dependencies, and existing package boundaries.
2. Keep APIs small and explicit; avoid framework-heavy abstractions unless already used.
3. Propagate context.Context through IO and request-scoped work.
4. Handle errors with enough context for operators and callers.
5. Add table-driven tests or integration tests where behavior crosses boundaries.

Checklist

• Goroutine lifetime, channel ownership, leaks, and cancellation.
• HTTP timeouts, request size limits, and graceful shutdown.
• Database pooling, transactions, migrations, and query cancellation.
• JSON validation, zero values, pointer semantics, and time handling.
• Race detector, benchmarks, pprof, and structured logs.

Output

Return:

• Code path summary.
• Concurrency and error-handling risks.
• Verification commands.
• Deployment notes.
