> **Before calling any skill in this module:** if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via `GET /skills/recommend?includeSchema=true`) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Triggers

• Improving testability
• Extracting logic for unit tests
• Planning a test strategy
• 提升可测试性、为单元测试抽取逻辑、规划测试策略

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.
