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.
