Go naming conventions prioritize clarity with unexported (lowercase) and exported (uppercase) identifiers. Error handling uses explicit checks, error wrapping for context, sentinel errors for comparison, and panic/recover sparingly. These patterns align with Go idioms and improve code maintainability.

Initialize a module with `go mod init`, organize code into logical packages, and apply concurrency patterns: goroutines for parallelism, channels for communication, worker pools for resource management, and context for cancellation. This layout enforces maintainability and follows Google's Go Style Guide.

Use goroutines for concurrent tasks and channels to coordinate communication between them. Leverage context to manage cancellation and timeouts across goroutine hierarchies. Worker pools distribute load efficiently. These patterns prevent deadlocks and resource leaks.

Write tests that exercise goroutines, channels, and context interactions. Use table-driven tests for systematic coverage. Run tests with the `-race` flag to detect data races. Combine unit tests with integration tests to verify concurrent behavior under load.

A standardized project layout—organizing packages, tests, and build artifacts logically—reduces cognitive load during code reviews and onboarding. It enforces separation of concerns and makes concurrent, error-prone code easier to reason about and maintain.

Yes. Context propagates cancellation, timeouts, and deadlines through function calls and goroutines. Retrofit existing code by threading context through function signatures. This enables graceful shutdown and resource cleanup without rewriting the entire application.
