Before writing any new code it requires a DRY check against internal/core/services and internal/core/ports. See solid-principles.md for the overview, the per-principle references for SRP/OCP/LSP/ISP/DIP detail, architecture-patterns.md for hexagonal/modular layout, and the templates for module/service/interface/handler/error/test scaffolding.

SOLID Go - Modular Architecture

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Analyze existing architecture
2. fuse-ai-pilot:research-expert - Verify Go docs via Context7
3. fuse-ai-pilot:sniper - Post-implementation validation

DRY - Reuse Before Creating (MANDATORY)
