Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00252 | $0.02341 |
| Opus 5.5 | $0.00101 | $0.00936 |
| Sonnet 5.5 | $0.00050 | $0.00468 |
| Haiku 4.5 | $0.00025 | $0.00234 |
Grade A, and why
unity-unitask-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
94% identical to unity-unitask-design — 22 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UniTask - Design Rules
Advisory module. Every rule is distilled from Cysharp UniTask source at:
- 2.5.10 —
[email protected](Unity 2018.4 baseline; actively used with 2022.3 / Unity 6)
Each rule cites a concrete file/line so the reasoning is auditable and the AI does not improvise against stale memory.
Mode: Documentation only — no REST skills to gate; load freely under any operating mode (Approval / Auto / Bypass).

Critical Rule Summary
| # | Rule | Source anchor |
|---|---|---|
| 1 | UniTask is a readonly partial struct (value type). Once awaited, its IUniTaskSource is recycled; awaiting the same UniTask variable twice throws. Use .Preserve() to obtain a memoized copy that can be awaited multiple times. |
UniTask.cs:34, UniTask.cs:103-113 |
| 2 | A UniTask returned by a method must be either awaited, .Forget()ed, or .AttachExternalCancellation(token)ed. Orphan UniTasks silently swallow exceptions into UniTaskScheduler.UnobservedTaskException. |
UniTaskScheduler.cs:13, UniTaskVoid.cs:11-17 |
| 3 | PlayerLoopTiming defines 16 timing slots (2020.2+; 14 on older Unity). Default UniTask.Yield() / UniTask.Delay uses PlayerLoopTiming.Update. Mixing LastPostLateUpdate with legacy WaitForEndOfFrame coroutines changes observed frame ordering. |
PlayerLoopHelper.cs:71-99 |
| 4 | UniTask.Delay(int ms, DelayType, PlayerLoopTiming, CancellationToken, bool cancelImmediately) accepts DelayType.DeltaTime / UnscaledDeltaTime / Realtime. The old bool ignoreTimeScale overload still exists but mixes semantics — prefer the DelayType overload for new code. |
UniTask.Delay.cs:12-20, UniTask.Delay.cs:147-165 |
| 5 | this.GetCancellationTokenOnDestroy() is defined for MonoBehaviour, GameObject, and Component in AsyncTriggerExtensions. Plain C# classes do NOT receive this extension — they must own a CancellationTokenSource explicitly. |
Triggers/AsyncTriggerExtensions.cs:14,22,28 |
| 6 | UniTask.WhenAll(params UniTask[] tasks) and the IEnumerable<UniTask> overload both exist. Semantically match Task.WhenAll but are zero-alloc when tasks are UniTask-native. WhenAny returns (winnerIndex, result) tuple for UniTask<T>. |
UniTask.WhenAll.cs:12,22,31,41, UniTask.WhenAny.cs |
| 7 | AsyncOperation.ToUniTask(IProgress<float>, PlayerLoopTiming, CancellationToken) is the canonical adapter. await operation works too but silently leaks the progress callback if you also set operation.completed += …. |
UnityAsyncExtensions.cs |
| 8 | UniTaskCompletionSource and UniTaskCompletionSource<T> support TrySetResult / TrySetException / TrySetCanceled. Once any of the three succeeds, subsequent calls return false — they do not throw. |
UniTaskCompletionSource.cs:573,610,754,792 |
| 9 | UniTask.SwitchToThreadPool() and UniTask.Run(...) are compile-time available on all platforms BUT throw NotSupportedException at runtime on WebGL. Guard with `#if !UNITY_WEBGL |
|
| 10 | Returning async UniTaskVoid is the fire-and-forget idiom that lets await be used INSIDE the method. async void methods cannot return UniTask — a common compile error when porting from Task. |
UniTaskVoid.cs:11-17, UniTask.Factory.cs:112-131 |
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 11d ago First seen · 86 lines · 252 tokens per session scan A d7779ec0864d
unity-unitask-design is a skill published in the GitHub repository dyCuong03/unity-agent-team (7 stars, last pushed 2mo ago), licensed MIT. It adds 252 tokens to every session and 2,341 once invoked, about $0.0010 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 94% identical to unity-unitask-design, differing in 22 lines, and is treated as a copy.

playtest-report
Structured playtest report template, or turn existing playtest notes into structured feedback.
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
motion
Reconstruct a skeleton from calibrated mesh projections and sequential VLM joint annotations, then fit joints and skin weights. Generate motion from joint-position trajectories, rhythm and contact constraints through IK; refine bone orientation against the action, then export, retarget and validate on the target mesh.
