Explain

Respond in the user's preferred language (detect from their recent messages, or fall back to the language setting in CLAUDE.md).

Explain the architecture and logic of a specified module or design in plain, approachable language.

In a Unity project: when explaining "how does X work right now", complement source-reading with live state queries via tykit (get-properties / get-field / get-array / inspect). This catches the common failure mode of explaining what the code says it does vs what it actually does. See shared/tykit-first.md.

Arguments: $ARGUMENTS

• Module or design name (e.g., "PlayerController", "inventory system", "save system")

Behavior

1. Read design docs: Start by checking for project documentation (e.g., Docs/, Documentation/, or AGENTS.md) to understand the design intent
2. Read core code: Find the key interfaces and implementation classes to understand the actual structure
3. Explain in plain language, following these principles:
   • Start with a real-world analogy to build intuition
   • Then break down the concrete code structure (use a tree diagram or simple illustration)
   • Explain "why it was designed this way" not just "what it is"
   • If there is a history of evolution (changed from A to B), explain the motivation
   • Point out common pitfalls or misconceptions
4. Do not:
   • Do not paste large blocks of source code; use pseudocode or key lines instead
   • Do not pile on design pattern terminology (say "each ship has its own service container", not "per-instance service locator pattern with dependency injection")
   • Do not assume the reader knows the project history
