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.

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 | $0.00059 | $0.00562 |
| Opus 5 | $0.00030 | $0.00281 |
| Sonnet 5 | $0.00012 | $0.00112 |
| Haiku 4.5 | $0.00006 | $0.00056 |
Grade A, and why
unity-tooling 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 8d 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 — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tooling Index
Install-once Editor script templates live under ../../tooling/<domain>/. Check here before writing a new Editor script from scratch.
When to Use
Reach for tooling/ when the task needs a persistent Editor-side helper rather than a one-shot Unity_RunCommand body. Signals:
- About to paste a
[MenuItem("Tools/...")]script viaUnity_CreateScript. - Need a tool the user re-runs from the Editor menu later (screenshots, exporters, custom build steps, batch operations).
- A recipe in
recipes/<domain>/carries a "Prerequisite: install Editor script" note pointing attooling/<domain>/.
Do NOT use for one-shot operations — those belong in recipes/<domain>/ and run through Unity_RunCommand.
Routing
- Open
../../tooling/<domain>/README.mdfor the domain that matches the task (e.g.tooling/ui/). - If a matching tool exists, install via
Unity_CreateScriptat the path the tool file specifies. - Wait for Unity to recompile — poll
EditorApplication.isCompiling(see UI Authoring Loop Phase 1 in../ui/SKILL.md). - Call the installed menu items via
EditorApplication.ExecuteMenuItem.
If no tool covers the case, write one — but check first.
Available domains
| Domain | Folder | Tools |
|---|---|---|
| test | ../../tooling/test/ |
test_runner_tool |
| ui | ../../tooling/ui/ |
ui_screenshot_tool |
Common Mistakes
- Pasting a
tooling/C# block intoUnity_RunCommand. These are install-once Editor scripts, notIRunCommandbodies — they will not compile in the RunCommand context. Always install viaUnity_CreateScriptat the path the tool file specifies. - Calling
EditorApplication.ExecuteMenuItemimmediately after install. Unity needs to recompile the new script before the menu items register. PollisCompilingfirst. - Treating
tooling/files as compile/run-gated likerecipes/. They have no validation gate — install into a scratch project once before trusting at scale.
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-tooling is a skill published in the GitHub repository batihandev/unity-mcp-skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 59 tokens to every session and 562 once invoked, about $0.0003 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 2026-08-31.
