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 | $0.00011 | $0.00760 |
| Opus 5 | $0.00005 | $0.00380 |
| Sonnet 5 | $0.00002 | $0.00152 |
| Haiku 4.5 | $0.00001 | $0.00076 |
Grade A, and why
unity-bookmark 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 5d 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 — 75 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
- Saving or restoring Scene View viewpoints
- Bookmarking camera angles
- Navigating saved scene locations
- 保存或恢复场景视角、收藏机位、在已存位置间切换
Bookmark Skills
Save and recall Scene View camera positions.
Guardrails
Operating Mode (v1.9 three-tier):
- Approval (default): 只有
bookmark_list标SkillMode.SemiAuto（纯读），Approval 模式下可直接执行，无需走 grant 协议。bookmark_set（Operation.Create，写入书签表）与bookmark_goto（Operation.Execute，改动编辑器选中对象与 Scene View 视角）都有副作用，走默认SkillMode.FullAuto，Approval 模式下需 grant。与workflow模块文档保持一致（以 C#WorkflowSkills.cs的特性标注为准）。 - Auto / Bypass: SemiAuto and FullAuto run directly.
- Auto-forbidden in this module:
bookmark_delete(SkillOperation.Delete). Reachable only under Bypass mode or via a user-managed Allowlist entry; the grant flow returnsMODE_FORBIDDEN. Bookmarks themselves are in-memory only —bookmark_deleteonly removes the entry, no asset I/O.
DO NOT (common hallucinations):
bookmark_savedoes not exist → usebookmark_setbookmark_load/bookmark_restoredo not exist → usebookmark_gotobookmark_removedoes not exist → usebookmark_delete- Bookmarks save Scene View position + current selection, not scene state
Routing:
- For workflow snapshots (object state undo) → use
workflowmodule - For scene save/load → use
scenemodule
Skills
bookmark_set
Save current selection and scene view position as a bookmark.
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| bookmarkName | string | Yes | - | Bookmark name |
| note | string | No | null | Optional note for the bookmark |
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-bookmark is a skill published in the GitHub repository Besty0728/Unity-Skills (1,701 stars, last pushed yesterday), licensed MIT. It adds 11 tokens to every session and 760 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 2026-08-30.
