UnitySkills is a REST API-based automation engine that lets AI coding agents control Unity Editor projects, including scenes and other editor operations. It is for developers using Unity with supported coding agents and IDEs. The catalogue skills and commands provide the agent workflows used to operate Unity projects through the engine.
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.

What it costs to keep this loaded
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 | $0.00020 | $0.02103 |
| Opus 5.5 | $0.00008 | $0.00841 |
| Sonnet 5.5 | $0.00004 | $0.00421 |
| Haiku 4.5 | $0.00002 | $0.00210 |
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 1mo 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.

How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.

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).

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.

unity-unitask-design is a skill published in the GitHub repository Besty0728/Unity-Skills (1,877 stars, last pushed yesterday), licensed MIT. It adds 20 tokens to every session and 2,103 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
script-execute
Compiles and runs C# in the Unity Editor (Roslyn): plain statements with the last expression as the result, or a full class with a static method. See the skill body for the modes, usings/include and Unity object parameters.
script-delete
Delete one or more .cs script files from disk, refresh the AssetDatabase, and wait for Unity compilation to settle before delivering the final result via the request's requestId. Pair with 'script-read' to inspect files before deletion.
script-read
Read a .cs script file and return its content as a string. Supports a 1-based lineFrom/lineTo slice for partial reads. Pair with 'script-update-or-create' to write back.
script-update-or-create
Write a .cs script file (create or overwrite) with the provided C# code. Validates syntax via Roslyn before write — invalid code is rejected with error details and the file is left untouched. Refreshes the AssetDatabase and delivers the final result via requestId after Unity finishes the triggered compilation. Use…

Use C#/.NET in Godot 4.7: partial classes extending nodes, the PascalCase lifecycle (Ready/Process/PhysicsProcess), [Export] fields, [Signal] delegates as C# events, type-safe node lookup, and calling between C# and GDScript. Use when writing Godot game code in C# (.cs files, .csproj), needing the Godot .NET build…
