Unity Systems Skills

A skill that teaches your agent how to architect and build reusable Unity game systems as modular UPM packages with ScriptableObject-driven architecture.

What This Does

When installed, your agent gains deep knowledge of how to:

• Structure gameplay systems as self-contained UPM packages
• Use ScriptableObject-driven architecture (SO Event Channels, ScriptableVariables, RuntimeSets)
• Wire cross-system communication without direct dependencies
• Apply modern Unity 6+ / C# 11 patterns (Awaitable, SerializeReference, etc.)
• Follow strict rules: composition over inheritance, no singletons, no god classes

Covers common systems like Inventory, Combat, Health, Dialogue, Save/Load, Quests, and AI with concrete decomposition patterns and integration strategies.
