Cursor Production‑Ready Go Project Structure Ruleset (cursorrules-go-project-structure.rules)

Stop spending hours debating folder names and chasing invisible production bugs. Start shipping Go services with a structure that’s already proven to work.

You know the pain: you open a new Go project and instantly fall into decision hell. Folders, configs, handlers, DI boundaries, logging patterns — none of it is hard, but it all eats time. Even then, you still miss things: a missing fallback in config parsing, an unwrapped error, a slow middleware chain you won’t notice until load testing.

This ruleset is a production-ready architecture encoded directly into Cursor. It enforces a complete Go project structure, configuration patterns, error-handling standards, dependency rules, and performance‑safe defaults. Instead of debating structure, Cursor simply generates the correct layout every time — with explanations for why each rule exists and what real-world failure it prevents.

What’s included:
- 1 full project layout ruleset enforcing a consistent, production-tested folder structure
- 14 configuration safety rules preventing exposed secrets, unsafe parsing, and missing fallbacks
- 9 HTTP middleware enforcement rules covering security, performance, and observability
- 11 logging and error-handling rules ensuring wraps, traces, and consistent fields
- 7 dependency injection and interface-boundary rules to avoid tight coupling and cyclic imports
- 6 performance rules guiding Cursor to generate low-allocation, memory-safe code paths
- 20+ examples of bad vs. good patterns with explanations tied to real production failures

Built from architecture patterns used in multi‑team Go microservice environments handling millions of requests per day, where consistency and stability mattered more than personal preference. Every rule exists because it prevented an actual outage, bottleneck, or debugging nightmare.

Who this is for:
- Go developers starting new services who want a structure they never have to rethink
- Senior engineers tired of reviewing the same structural mistakes in every PR
- Solo builders who want production best practices without spending weeks studying patterns

Who this is NOT for:
- Developers who prefer to invent their own folder structure every project
- Anyone building tiny throwaway scripts rather than long‑lived services

If this doesn’t save you at least 4 hours on your next project setup, reach out for a full refund.
