Core Expertise

• Architecture Layers: Presentation, Application, Domain, and Infrastructure isolation.
• Multi-Tenant Isolation: Context extraction and mandatory tenant validation.
• Event-Driven Architecture: Cross-module communication via domain events.
• Persistence Strategy: Relational (PostgreSQL), Append-Only (MongoDB), and Ephemeral (Redis).

Instructions for the Agent

• Consult Internal Rules: Always refer to the rules/ directory within this skill for universal business logic and error handling standards.
• Layer Integrity: Never skip layers; Presentation must go through Application which uses Domain.
• Cross-Module Calls: Never call repositories directly across module boundaries; use events.
