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 | $0.00014 | $0.02001 |
| Opus 5 | $0.00007 | $0.01001 |
| Sonnet 5 | $0.00003 | $0.00400 |
| Haiku 4.5 | $0.00001 | $0.00200 |
Grade A, and why
unity-shader 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 — 205 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
- Creating or editing handwritten shaders
- Listing or finding .shader files
- Inspecting properties/keywords
- 创建或编辑手写 shader、列出/查找 .shader 文件、检查属性与关键字
Unity Shader Skills
Work with .shader HLSL/ShaderLab files (create from templates, read source, list, find, get keywords/properties/variants, check errors, delete, toggle global keywords). For node-based ShaderGraph use the shadergraph module.
Operating Mode
- Query skills (
shader_read,shader_list,shader_find,shader_get_properties,shader_check_errors,shader_get_keywords,shader_get_variant_count) areSkillMode.SemiAuto— they run in all three modes without grant. - Mutating skills (
shader_create,shader_create_urp,shader_set_global_keyword) areSkillMode.FullAuto— under Approval they need user grant (grant triggers one server-side execute returning the result); under Auto / Bypass they execute directly. shader_deletecarriesSkillOperation.Deleteand is auto-forbidden in Approval / Auto modes (NeverInSemi). Only Bypass or the user-managed Allowlist can run it.
Guardrails
DO NOT (common hallucinations):
shader_set_propertydoes not exist → usematerial_set_float/material_set_color/etc. on the material, not the shadershader_apply/shader_assigndo not exist → usematerial_set_shaderto change a material's shadershader_get_propertiesreturns shader property definitions (name/type/range), not current values → for material instance values usematerial_get_properties- Shader names are case-sensitive and path-like:
"Standard","Universal Render Pipeline/Lit", not"standard"or"URP Lit"
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-shader is a skill published in the GitHub repository Besty0728/Unity-Skills (1,727 stars, last pushed today), licensed MIT. It adds 14 tokens to every session and 2,001 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.
