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 | $0.00021 | $0.00842 |
| Opus 5 | $0.00010 | $0.00421 |
| Sonnet 5 | $0.00004 | $0.00168 |
| Haiku 4.5 | $0.00002 | $0.00084 |
Grade A, and why
unity-shadergraph-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 6d 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 — 69 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.
Triggers
- Building or reviewing Shader Graphs
- Structuring node chains or SubGraphs
- Laying out blackboard/keywords
- Following URP/HDRP graph recipes
- 构建或审查 Shader Graph、组织节点链或 SubGraph、布置黑板/关键字、参考 URP/HDRP 图配方
ShaderGraph - Design Rules
Advisory module. Read this before giving Shader Graph guidance. The goal is to keep recommendations anchored to actual package/source behavior, not stale model memory.
Mode: Documentation only — no REST skills to gate; load freely under any operating mode (Approval / Auto / Bypass).
Source Scope
Validated against:
- Unity 2022.3 package source:
E:/CodeSpace/temp/shadergraph/[email protected] - Unity 6 Graphics source:
E:/CodeSpace/temp/Graphics/Packages/com.unity.shadergraph - Runtime/editor behavior in this repo's ShaderGraph skills and dual-version test environments
Core anchors:
Editor/Data/Graphs/GraphData.csEditor/Data/Nodes/AbstractMaterialNode.csEditor/Data/Interfaces/Graph/SlotReference.cs- Specific node files under
Editor/Data/Nodes/...
When To Load
Load before:
- Designing a new Graph or SubGraph architecture
- Reviewing a proposed Shader Graph node chain
- Advising on blackboard properties, keywords, samplers, or SubGraph boundaries
- Suggesting changes to graphs through the constrained
shadergraph_*node editing skills
What This Module Assumes
- Graph editing is limited to the current safe node whitelist exposed by
shadergraph_list_supported_nodes - Guidance must stay inside what Unity 2022.3 and Unity 6 both support
shadergraph_get_structureis the fact source for current node ids, slot ids, and live topology- The practical overlap is 28 nodes across both versions;
AppendVectorNodeis currently Unity 6 only in live validation
What ships with it
5 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-shadergraph-design is a skill published in the GitHub repository Besty0728/Unity-Skills (1,727 stars, last pushed today), licensed MIT. It adds 21 tokens to every session and 842 once invoked, about $0.0001 per session on Opus 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.
