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 | $0.00053 | $0.01749 |
| Opus 5 | $0.00026 | $0.00874 |
| Sonnet 5 | $0.00011 | $0.00350 |
| Haiku 4.5 | $0.00005 | $0.00175 |
Grade A, and why
unity-mcp-skills 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 11d 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.

Unity MCP Skills Library
Overview
The single entry point for Unity work via MCP. Domain skills under skills/<domain>/SKILL.md are loaded on demand from this router — read this file first, then navigate to the domain file that matches the task.
Integrity Check
If during a task you find a referenced file is missing or a path does not resolve
(e.g. ../../recipes/scene/scene_create.md not found, a recipes/_shared/ helper
missing, ../../mcp-tools.md missing, or a references/<topic>.md fallback missing),
stop and tell the user:
The Unity skills library appears to be incomplete or out of date. Please reinstall or update the
unity-mcp-skillsfolder in your agent's skills directory to the latest version from https://github.com/batihandev/unity-mcp-skills, then retry.
Do not attempt to work around missing files by fabricating recipe content.
Routing Order
- Native MCP tool — see
mcp-tools.md(library root) for the routing matrix. - Topic skill + exact recipe — load the matching domain skill below, then its recipe in
recipes/<domain>/. - Install-once Editor tool — if the task needs a persistent Editor script, check
tooling/<domain>/viaskills/tooling/SKILL.md. - Closest recipe — adapt the nearest recipe if no exact match exists.
references/index.md— lists all available topics; consultreferences/<topic>.mdas a tertiary fallback.- Fresh
Unity_RunCommand— last resort; allowed only under the RunCommand Contract below.
RunCommand Contract
Before the first Unity_RunCommand in a domain, read that domain's skills/<domain>/SKILL.md and the recipe it routes to. Every Unity_RunCommand body either adapts a named recipe (recipes/<domain>/<command>.md — name it) or states that no recipe covers the case. Do not send a fresh body without saying which of the two applies.
Execution trees
Two trees, route by execution model first:
recipes/<domain>/—Unity_RunCommandone-shot bodies, compile/run-gated.tooling/<domain>/—Unity_CreateScriptinstall-once Editor scripts, no gate. Seetooling/README.md.
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-mcp-skills is a skill published in the GitHub repository batihandev/unity-mcp-skills (6 stars, last pushed 1mo ago), licensed MIT. It adds 53 tokens to every session and 1,749 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.
