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 | $0.00011 | $0.01162 |
| Opus 5 | $0.00005 | $0.00581 |
| Sonnet 5 | $0.00002 | $0.00232 |
| Haiku 4.5 | $0.00001 | $0.00116 |
Grade A, and why
unity-patterns 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 2d 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 — 87 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.

- Deciding which pattern fits a problem
- Structuring decoupled systems

Unity Pattern Selector
Use this skill to decide whether a pattern is justified. Do not recommend every pattern at once.
Guardrails
Mode: Documentation only — no REST skills to gate; load freely under any operating mode (Approval / Auto / Bypass).
- Recommend at most 1-3 patterns, and explain why simpler options are not enough.
Pattern Guide
-
ScriptableObject- Use for authored config, shared static data, event channels, and reusable data assets.
- Avoid as the default home for per-run mutable gameplay state.
-
C# events / delegates- Use for one-to-many notifications with clear ownership and unsubscribe points.
- Avoid for imperative flows that need ordering, return values, or complex debugging.
-
Global event bus / observer hub- Use sparingly and only when many systems truly need broad decoupled notifications.
- Avoid as the default answer to coupling. It often hides ownership and makes debugging harder.
-
Interfaces- Use when multiple implementations or clearer dependency boundaries are needed.
- Avoid adding interfaces around every class without a real seam.
-
State machine- Use for actors with mutually exclusive states and explicit transitions.
- Avoid when a few booleans or a small command flow is enough.
-
Object pool- Use for frequent spawn/despawn of bullets, VFX, enemies, UI items.
- Avoid for rare objects or when lifetime is simple.
-
Service layer- Use for a small number of cross-scene systems with explicit bootstrap and interfaces.
- Avoid turning everything into hidden singletons or service locators.
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-patterns is a skill published in the GitHub repository Besty0728/Unity-Skills (1,695 stars, last pushed today), licensed MIT. It adds 11 tokens to every session and 1,162 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.

img2mo-std
Standardize a 2D animation baseline image with /img2mo-std xxx.png/pos. Use when preparing a character, creature, prop, or weapon baseline before motion generation, especially if the source image is too large, tightly cropped, lacks transparent action margin, has a white background, or later walk/attack/idle frames…
