# Skill: Craft Shared Domain > "Shared should be small. Large Shared means restructuring needed." ## The Standard 1. **Cross-Cutting Only**: Audit, logging, base classes—truly shared concerns. 2. **Keep Minimal**: If Shared grows large, domains need restructuring. 3. **No Business Logic**: Shared is infrastructure, not domain rules. 4. **Alternative: Support**: Use `src/Support/` for utilities instead. ## The Anti-Patterns | ❌ Don't | ✅ Do | Why | |----------------------------|-----------------------------|-----------------------------| | Dump "common" code | Place in owning domain | Someone owns it | | Business logic in Shared | Keep in specific domain | Business != shared | | Large Shared namespace | Split into domains | Shared is a smell | ## Real-World Examples See [examples.md](examples.md).
