  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Unity Dotween Design is an agent skill from Besty0728/Unity-Skills. Source-anchored design rules for DOTween 1.3.015

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files (for example `BASICS.md`, `EASE.md` and `INTEGRATION.md`).

It sits in Game Development. The repository describes itself as: AI automation skills specifically designed for Unity. The licence is MIT.

When your agent uses it

  • Game Development work in your project

Example prompts

  • “/unity-dotween-design”

What it can do on your machine

Read from SKILL.md and the folder at commit 12a40e4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Unity Dotween Design loads about 2k tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 782 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~17
When it runs · the whole SKILL.md, loaded when a task matches
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Source-anchored design rules for DOTween 1.3.015

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

  • Writing or reviewing DOTween code
  • Building sequences
  • Binding tween lifetime
  • Debugging tween pitfalls
  • 编写或审查 DOTween 代码、构建序列动画、绑定补间生命周期、排查补间陷阱

DOTween - Design Rules

Advisory module. Every rule is distilled from Demigiant DOTween source at:

  • 1.3.015 — bundled in _DOTween.Assembly/DOTween/ and bin/Modules/ module files (Unity 2018+)

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).

When to Load This Module

Load before writing or reviewing any of:

  • DOTween.Init(...) bootstrap, DOTweenSettings configuration, SetTweensCapacity adjustments
  • Any .DOMove / .DORotate / .DOScale / .DOColor / .DOFade / .DOShake* / .DOPath / .DOPunch* shortcut call
  • DOTween.Sequence() + .Append / .Join / .Insert / .Prepend / .AppendInterval / .PrependInterval / .AppendCallback
  • .SetEase / .SetDelay / .SetLoops / .SetAutoKill / .SetLink / .SetId / .SetTarget / .SetUpdate / .SetRelative / .SetRecyclable / .SetSpeedBased
  • .OnStart / .OnUpdate / .OnStepComplete / .OnComplete / .OnKill / .OnPlay / .OnPause / .OnRewind
  • .AsyncWaitForCompletion / .AsyncWaitForKill / .AsyncWaitForRewind / .AsyncWaitForElapsedLoops / .AsyncWaitForPosition
  • tween.ToUniTask(TweenCancelBehaviour, CancellationToken) (UniTask bridge)
  • DOTween.Kill(target, complete) / DOTween.KillAll() batch operations
  • Safe Mode debugging — useSafeMode, safeModeLogBehaviour, nestedTweenFailureBehaviour
  • DOTween Module generation (Audio / Physics / Physics2D / Sprite / UI / UnityUI / TextMeshPro)

Critical Rule Summary

#RuleSource anchor
1DOTween.Init(recycleAllByDefault, useSafeMode, logBehaviour) returns IDOTweenInit for fluent .SetCapacity(...). If not called explicitly, Auto-init runs on first tween creation (AutoInit at DOTween.cs:236). DOTween.Version = "1.3.015" is exposed as a const.DOTween.cs:38,227,236,243
2Every tween is driven by a single [DOTween] GameObject MonoBehaviour (DOTweenComponent) marked DontDestroyOnLoad. It is created on first init and survives scene loads. Don't destroy it — DOTween.Clear(destroy: true) is the only supported teardown.DOTweenComponent.cs:268-270, DOTween.cs:311
3Default autoKill = true: tween is killed on completion. After kill, calls like .Restart() / .Kill() / .Complete() are no-ops (Safe Mode) or NullReferenceException (Safe Mode off). Use .SetAutoKill(false) to keep tween alive for replay.DOTween.cs useSafeMode:49, TweenSettingsExtensions.cs:39,49
4Safe Mode is ON by default (useSafeMode = true). Target destroyed while tween plays → Safe Mode catches the exception and logs per safeModeLogBehaviour (default: Warning). Disable Safe Mode to locate missing-link bugs during development.DOTween.cs:49,51
5SetLink(gameObject, LinkBehaviour) binds tween lifecycle to a GameObject. Default LinkBehaviour.KillOnDestroy. Without SetLink, tween continues running after target is destroyed and relies on Safe Mode for protection.TweenSettingsExtensions.cs:91,103, LinkBehaviour.cs
6SetTarget(object target) is required for DOTween.Kill(target) / DOTween.KillAll(target) grouping. Shortcut extensions (.DOMove, .DOFade, etc.) set target automatically; manual DOTween.To(...) does NOT.TweenSettingsExtensions.cs:116, DOTween.cs:884,892
7Sequence.Append(t) runs after previous. Sequence.Join(t) runs in parallel with previous. Sequence.Insert(float atPosition, t) inserts at absolute time. Sequence.Prepend(t) pushes to front, shifting existing.TweenSettingsExtensions.cs:499,508,517,528
8AsyncWaitForCompletion / AsyncWaitForKill / AsyncWaitForRewind live in DOTweenModuleUnityVersion.cs (MODULE file, gated by `UNITY_2018_1_OR_NEWER && (NET_4_6
9UniTask bridge tween.ToUniTask(TweenCancelBehaviour, CancellationToken) lives in UniTask's External/DOTween/ extensions and is the recommended await path over AsyncWaitForCompletion. TweenCancelBehaviour has 9 values (Kill / Complete / CancelAwait / KillAndCancelAwait / ...).UniTask DOTweenAsyncExtensions.cs:14-27,54
10Ease enum has 38 entries (36 user-facing + 2 reserved INTERNAL_*): Unset / Linear + In/Out/InOut variants of Sine/Quad/Cubic/Quart/Quint/Expo/Circ/Elastic/Back/Bounce (10 × 3 = 30 math eases) + Flash / InFlash / OutFlash / InOutFlash. INTERNAL_Zero and INTERNAL_Custom are auto-assigned by DOTween for zero-duration and AnimationCurve-based tweens.Ease.cs:9-53

Routing to Other Modules

  • Async integration (ToUniTask, AsyncWaitForCompletion) → load unitask-design and async
  • UI animation (uGUI / UIToolkit) choice between DOTween and native animators → load inspector
  • Architecture / performance review of tween-heavy scenes → load performance
  • Asmdef layout for DOTween consumers (DOTween.asmdef, DOTween Modules asmdef) → load asmdef
  • Addressables-loaded prefab tween lifetime (bundle unload vs tween running) → load addressables-design

Version Scope

Targets DOTween 1.3.015 (the Pro/Free source bundled in _DOTween.Assembly/). Version is exposed as the const DOTween.Version = "1.3.015" at DOTween.cs:38.

Earlier 1.2.x versions are source-compatible for most APIs. Key differences:

  • Modules system (UI / TMP / Physics / etc.) requires post-1.2.0 source and the Utility Panel scanner.
  • SetLink was added in 1.2.x series; LinkBehaviour.KillOnDestroy vs KillOnDisable variants in later 1.2/1.3.
  • TweenCancelBehaviour (UniTask bridge) shipped separately via the UniTask package.

When in doubt, read the cited source — not your memory.
