What it does

Unity Development is an agent skill from CoWork-OS/CoWork-OS. Unity/C development: MonoBehaviour lifecycle, ScriptableObjects, Addressables, URP/HDRP, physics, UI, editor scripting, and CLI builds.

Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/full-guidance.md`).

It sits in Game Development, covering Game development. It works with C# and Godot. The repository describes itself as: Local-first personal agentic OS and everything app for coding, knowledge work, web design, automations, and artifacts. The licence is MIT.

When your agent uses it

  • Tasks that involve Game development

Example prompts

  • “/unity-development”

What it can do on your machine

Read from SKILL.md and the folder at commit a77d646. 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

    Ships 1 file in scripts/, which the agent can run.

    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 Development loads about 439 tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 190 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~439
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

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); the scripts in this folder are not scanned.

Purpose

Unity/C# development: MonoBehaviour lifecycle, ScriptableObjects, Addressables, URP/HDRP, physics, UI, editor scripting, and CLI builds.

Routing

  • Use when: Use when the user asks about Unity, C# game scripting, MonoBehaviour, ScriptableObjects, Addressables, URP, HDRP, Unity CLI builds, or Unity Editor scripting.
  • Do not use when: Do not use for Unreal Engine (use unreal-development), Godot (use the game pack's godot skill), or cross-engine performance (use game-performance).
  • Outputs: C# scripts, Unity configurations, CLI commands, and Unity development guidance.
  • Success criteria: Returns valid C# code or Unity CLI commands.

Trigger Examples

Positive
  • Use the unity-development skill for this request.
  • Help me with unity development.
  • Use when the user asks about Unity, C# game scripting, MonoBehaviour, ScriptableObjects, Addressables, URP, HDRP, Unity CLI builds, or Unity Editor scripting.
  • Unity Development: provide an actionable result.
Negative
  • Do not use for Unreal Engine (use unreal-development), Godot (use the game pack's godot skill), or cross-engine performance (use game-performance).
  • Do not use unity-development for unrelated requests.
  • This request is outside unity development scope.
  • This is conceptual discussion only; no tool workflow is needed.

Runtime Prompt

  • Current runtime prompt length: 848 characters.
  • Runtime prompt is defined directly in ../unity-development.json.
