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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00009 | $0.02596 |
| Opus 5 | $0.00005 | $0.01298 |
| Sonnet 5 | $0.00002 | $0.00519 |
| Haiku 4.5 | $0.00001 | $0.00260 |
Grade A, and why
unity-asset 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 — 278 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.

Unity Asset Skills
BATCH-FIRST: Use
*_batchskills when operating on 2+ assets.
Operating Mode
- Approval：本模块 Mixed ——
asset_find/asset_get_info/asset_get_labels标SkillMode.SemiAuto，可直接执行；写类 skill (asset_move/asset_move_batch/asset_duplicate/asset_create_folder/asset_create_folder_batch/asset_refresh/asset_reimport*/asset_set_labels) 走默认SkillMode.FullAuto，需 grant。 - Auto / Bypass：FullAuto 直接执行。
- 含 NeverInSemi 高危 skill：
asset_import/asset_import_batch(标RiskLevel = "high"—— 写入项目)；asset_delete/asset_delete_batch(Operation.Delete)。这些在 Approval/Auto 下返MODE_FORBIDDEN，仅 Bypass 或 Allowlist 命中可调。
DO NOT (common hallucinations):
asset_createdoes not exist → useasset_create_folder(folders),material_create(materials),script_create(scripts)asset_renamedoes not exist → useasset_movewith new pathasset_searchdoes not exist → useasset_findwith searchFilter syntax (e.g.t:Texture2D player)asset_copydoes not exist → useasset_duplicate
Routing:
- For texture/model/audio import settings → use
importermodule (SkillMode.FullAuto) - For material creation → use
materialmodule (SkillMode.FullAuto) - For script creation → use

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-asset is a skill published in the GitHub repository Besty0728/Unity-Skills (1,707 stars, last pushed yesterday), licensed MIT. It adds 9 tokens to every session and 2,596 once invoked, about $0.0000 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 2026-08-30.
