About this skill

Unity Scriptdesign is a skill in Besty0728/Unity-Skills (1.8k stars). Its SKILL.md is about 1.1k tokens. Licence: MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit ec8aa7c. 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 Scriptdesign loads about 1.1k tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 568 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~15
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Advise on Unity gameplay script quality

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

  • Reviewing code quality
  • Untangling tightly-coupled scripts
  • Planning a refactor for maintainability
  • 审查代码质量、理顺高耦合脚本、为可维护性规划重构

Unity Script Design Review

Use this skill before creating gameplay scripts, or after scripts are generated and need a design pass.

Review Checklist

  • Responsibility: does the script have one clear job?
  • Role: should it really be a MonoBehaviour, ScriptableObject, or plain C# class?
  • Coupling: are dependencies explicit instead of hidden globals or deep scene lookups?
  • Communication: should this be a direct reference, interface call, or event?
  • Performance: is there unnecessary Update, repeated Find, avoidable allocation, or reflection in hot paths?
  • Lifecycle: are subscriptions, timers, and async work cleaned up clearly?
  • Inspector UX: are serialized fields private, grouped, and explained?
  • Testability: can the core logic move into a plain C# class?
  • Naming: do class and field names explain intent without cryptic abbreviations?

Data Lifecycle Boundary

The Review Checklist above asks "where does this class live". Ask the same question for every field. Every piece of state has one of three lifecycles, and putting a field on the wrong one is the most common cause of "why did this break when the designer tweaked a value" and "why are my unit tests flaky".

LifecycleWhen the value is decidedWhere it belongsTypical idiom
Authoring-timeBy a designer in the Editor, before PlayScriptableObject asset, or [SerializeField] private on a prefabImmutable at runtime; read via _config.Speed
Composition-timeOnce per scene/instance, at Awake/Startprivate field, assigned from GetComponent / GetComponentInChildren / ctor argCached reference, no per-frame lookup
Runtime-mutableEvery frame or on gameplay eventsprivate backing field + public read-only property + eventExposed via public float Health { get; private set; } + OnHealthChanged
Show full SKILL.md (248 more words)Show less
Typical assignments
  • Weapon damage / fire rate / clip size → Authoring-time (ScriptableObject so balance can be hot-swapped).
  • Enemy AI's current target Transform → Composition-time if set once at spawn, Runtime-mutable if re-targeted each frame.
  • Player current HP → Runtime-mutable with event. Never public float hp;.
  • Reference to Rigidbody/Animator on the same GameObject → Composition-time, cached in Awake.
  • Level music track → Authoring-time via ScriptableObject level descriptor.
  • "Is in combat" flag → Runtime-mutable, but usually derived from other state — review whether it should be a field at all.
Why the separation matters

Mixing the three lifecycles is what turns a clean class into a god object. A MonoBehaviour whose public float speed is edited by both the Inspector and a power-up script has two owners and no invariant; a bug in either path corrupts the other. The ECS baking pipeline makes this distinction a hard architectural boundary (Authoring → Baker → System), and the discipline transfers directly: if you would not mix an Authoring component with runtime write-back in ECS, do not mix them in a MonoBehaviour either. Source: EntitiesSamples/Docs/baking.md:5-16.

Guardrails

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

  • Prefer descriptive names over local shorthand.
  • Do not “optimize” readability away for imagined productivity gains.
  • Do not recommend complex patterns if a smaller refactor fixes the real problem.

Output Format

  • Keep: what is already good
  • Simplify: what should stay straightforward
  • Refactor: the highest-value structural change
  • Performance notes: only real hotspots, not theoretical micro-optimizations
  • Maintainability notes: naming, ownership, coupling, editor usability

Questions about Unity Scriptdesign

How do I install Unity Scriptdesign in Claude Code?

Run `npx skills add Besty0728/Unity-Skills --skill unity-scriptdesign -a claude-code`. Or copy the skill folder (SkillsForUnity/unity-skills~/skills/scriptdesign in Besty0728/Unity-Skills) into .claude/skills/unity-scriptdesign in your project. Claude Code loads it when a task matches its description.

How do I install Unity Scriptdesign in Codex?

Run `npx skills add Besty0728/Unity-Skills --skill unity-scriptdesign -a codex`. Or copy the skill folder (SkillsForUnity/unity-skills~/skills/scriptdesign in Besty0728/Unity-Skills) into .agents/skills/unity-scriptdesign in your project. Codex loads it when a task matches its description.

Can I use Unity Scriptdesign in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Besty0728/Unity-Skills --skill unity-scriptdesign -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/unity-scriptdesign, .gemini/skills/unity-scriptdesign, .github/skills/unity-scriptdesign and .opencode/skills/unity-scriptdesign in your project.

What does Unity Scriptdesign need to run?

SKILL.md names no scripts, command-line tools or credentials: Unity Scriptdesign is instructions for the agent only.

Does Unity Scriptdesign access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Unity Scriptdesign safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Unity Scriptdesign use?

Unity Scriptdesign is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Unity Scriptdesign use?

About 1.1k tokens (SKILL.md is roughly 4.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
