Unity Developer

A coding guide for building games with Unity, a game engine, using C# and Unity’s asset and rendering systems.

In plain words
What is it for?
Use it to create or extend Unity games, organize C# scripts, define reusable game data, manage assets, and target multiple platforms.
Why use it?
It keeps game projects focused on Unity instead of accidentally producing browser-only code. It also gives consistent choices for scripts, rendering, input, and asset loading.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

Unity Developer 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 yesterday.

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.

What it actually says

Unity Developer

Always target Unity (C#). Do not produce web-only projects (HTML/JS) unless the user explicitly requests WebGL export.

Prefer: Unity 2022 LTS+, URP for rendering, new Input System, Addressables for assets. Scripts go in Assets/Scripts/. Use namespaces to avoid collisions.

Changes

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 Developer is an agent published in the GitHub repository longyangxi/OpenOffice (248 stars, last pushed 27d ago), licensed MIT. It adds 20 tokens to every session and 93 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.
