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 | $0.00011 | $0.01423 |
| Opus 5 | $0.00005 | $0.00711 |
| Sonnet 5 | $0.00002 | $0.00285 |
| Haiku 4.5 | $0.00001 | $0.00142 |
Grade A, and why
unity-shadergraph 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 — 136 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.

ShaderGraph Skills
Shader Graph asset workflows for Unity 2022.3+ with source-backed template handling, MultiJson inspection, and constrained internal-editor reflection writes.
Operating Mode
- Query skills (
shadergraph_list_templates,shadergraph_list_assets,shadergraph_get_info,shadergraph_get_structure,shadergraph_list_supported_nodes,shadergraph_list_properties,shadergraph_list_keywords) areSkillMode.SemiAuto— they run in all three modes without grant. - All other mutators (create graph / subgraph, add/move/connect/disconnect node, set node defaults/settings, add/update property/keyword, reimport) are
SkillMode.FullAuto— under Approval they need user grant (grant triggers one server-side execute returning the result); under Auto / Bypass they execute directly. shadergraph_remove_node,shadergraph_remove_property,shadergraph_remove_keywordcarrySkillOperation.Deleteand are auto-forbidden in Approval / Auto modes (NeverInSemi). Only Bypass or the user-managed Allowlist can run them.
Reflection Fragility
This module reaches into UnityEditor.ShaderGraph and UnityEditor.ShaderGraph.Internal via reflection (see ShaderGraphReflectionHelper.cs and ShaderGraphNodeRegistry.cs). The supported node whitelist, slot layout, and settings keys are version-pinned to com.unity.shadergraph 14.0.x (Unity 2022.3) with limited Unity 6 coverage. Treat the following as a hard contract:
- Never assume an internal type, field, or slot id exists from memory — always cross-check with
shadergraph_list_supported_nodesandshadergraph_get_structurefirst. - If a Shader Graph package update changes internal types or
MultiJsonschema, mutators may fail or silently no-op until the registry is updated. - If a skill returns an error mentioning a reflection / type lookup failure, do not retry with different argument shapes — report the version mismatch and stop.
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 is a skill published in the GitHub repository Besty0728/Unity-Skills (1,727 stars, last pushed today), licensed MIT. It adds 11 tokens to every session and 1,423 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.
