SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill addresses the complexity of building maintainable application layers in Go by enforcing a strict CQRS architecture that separates command-driven mutations from query-optimized reads.

Core Features & Use Cases

  • Transaction-Boundary Enforcement: Ensures atomicity by managing pgx transactions within the service layer, preventing partial state updates.
  • Three-Tier Validation: Provides a clear separation between structural, orchestration, and business-invariant validation logic.
  • Parallel Query Orchestration: Uses errgroup for efficient, concurrent data fetching while maintaining strict memory safety through ad hoc confinement.
  • Use Case: Use this skill to implement a new command handler that requires multi-call atomicity, idempotency checks, and authorization before domain mutation.

Quick Start

Use the go-service-layer skill to generate a new command handler that follows the standard Handle signature and transaction-boundary requirements.

FAQPage Schema
How do I implement CQRS command handlers in Go service layers?

CQRS in Go services separates command-driven mutations from query-optimized reads using distinct handlers. This architecture manages domain logic orchestration and transaction boundaries to ensure atomic state updates within the application layer.

How do I manage pgx transaction boundaries in a Go backend application layer?

Managing pgx transaction boundaries in a Go backend requires the service layer to enforce atomicity, preventing partial state updates during multi-call domain mutations. This ensures robust transaction management within enterprise-grade systems.

What is the best way to execute parallel queries concurrently in Go without memory safety issues?

Executing parallel queries concurrently in Go is best achieved using errgroup for efficient data fetching while maintaining strict memory safety through ad hoc confinement, preventing race conditions during concurrent read operations.

How do I structure multi-tier validation logic for Go backend architecture?

Structuring multi-tier validation logic in Go backend architecture involves providing a clear separation between structural, orchestration, and business-invariant validation boundaries to ensure data integrity before domain mutation.

Can I use Go service layer architecture for idempotency checks and authorization?

Yes, Go service layer architecture supports idempotency checks and authorization requirements. It orchestrates these checks alongside multi-call atomicity before executing domain mutations within enterprise-grade backend systems.

When do I need to separate commands and queries in Go backend systems?

You need to separate commands and queries in Go backend systems when building maintainable application layers that require optimized reads, strict transaction boundaries, and complex domain logic orchestration for enterprise-grade scale.
