Unity Async

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

• Choosing Update/coroutine/UniTask/timer
• Handling cancellation and cleanup
• 在 Update/协程/UniTask/定时器间取舍、处理取消与清理

Unity Async Strategy

Scope: this module is about async code you write into the Unity runtime — Update, coroutines, UniTask, cancellation and lifecycle ownership. It is not about the REST protocol's own async jobs. For jobId / polling / job_status / GET /jobs/{id}, see batch.

Use this skill when the user is deciding how runtime work should be scheduled or cleaned up.

Guardrails

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

• Do not recommend UniTask just because it looks more advanced than coroutine.
• Prefer the simplest scheduling model that fits the use case.

Decision Ladder

1. First ask whether the task needs per-frame work at all.
2. If not, prefer events, callbacks, or explicit method calls.
3. If a short Unity-bound sequence is needed, prefer coroutine.
4. Recommend UniTask only when:
   • the project already uses it, or
   • the user explicitly wants it and accepts the dependency.
5. Use Update only for true continuous simulation, polling, or input loops that cannot be event-driven.

Specific Guidance

• Avoid many unrelated Update methods if a more event-driven flow works.
• Cache references used in hot paths.
• Always define lifecycle ownership:
  • who starts the work
  • who cancels or stops it
  • when it is cleaned up
• In MonoBehaviour, prefer OnEnable / OnDisable / OnDestroy for subscribe-unsubscribe symmetry.
• Use IDisposable mainly for pure C# lifetimes, temporary subscriptions, or scope-based cleanup helpers, not as a cargo-cult replacement for Unity lifecycle methods.

Output Format

• Recommended scheduling model
• Why it fits
• Lifecycle / cancellation owner
• Hot-path risks
• Why the heavier alternative is unnecessary, if applicable
