Unity Testability Advisor

Use this skill when deciding what logic should remain in Unity-facing classes and what should move into pure C# code.

Review Questions

• Can the rule/algorithm run without `Transform`, `GameObject`, or scene state?
• Can config be injected instead of read through static globals?
• Can runtime decisions be moved to a plain C# class and called from a thin `MonoBehaviour`?
• Does this need PlayMode coverage, or is EditMode enough?

Output Format

• Logic that should move to pure C#
• Logic that should stay Unity-facing
• Suggested seams/interfaces
• Candidate EditMode tests
• Candidate PlayMode tests

Guardrails

> **Mode**: Documentation only — no REST skills to gate; load freely under any operating mode (Approval / Auto / Bypass).

• Do not force test seams everywhere if the script is tiny and scene-bound.
• Prefer a few meaningful seams over abstraction for its own sake.
