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 | $0.00013 | $0.00267 |
| Opus 5 | $0.00006 | $0.00133 |
| Sonnet 5 | $0.00003 | $0.00053 |
| Haiku 4.5 | $0.00001 | $0.00027 |
Grade A, and why
unreal 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 6d 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.
What it actually says
Working with Unreal Engine
- We are using Unreal Engine 5.5.4, so be extremely cautious of using deprecated or outdated APIs, includes or practices.
Coordinate System
In the Unreal Editor, the following colors are associated with the coordinate axes:
X-axis: Red Y-axis: Green Z-axis: Blue
UE's Z-up, left-handed coordinate system is defined as follows:
The Z-axis determines how far up and down along a vertical line an actor is located. Positive values are upwards. The Y-axis determines how far to the left or right an actor is located. Positive values are to the right. The X-axis determines how far forward or backward an actor is located. Positive values are forward.
Units
Unreal Engine (UE) defaults to the following International System (SI) units for measurement:
Quantity Unit Distance/Length Centimeters (cm) Mass Kilograms (kg) Time Minutes (min), Seconds (s) Angles Degrees (deg) Speed/Velocity Meters per Second (m / s) Temperature Celsius (C) Force Newtons (N) Torque Newton Meters (N • m)
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.

unreal is a cursor rule published in the GitHub repository gingerol/UnrealEngine-ai-mcp (5 stars, last pushed 1y ago), licensed MIT. It adds 13 tokens to every session and 267 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 2026-08-31.
Other cursor rules, from other repositories
08-client-server
Rules for separating client-side and server-side code in Fabric 1.14.4 Minecraft mods. Fabric is a Minecraft modding framework, and client code runs in the player’s game while server code runs the game world.
07-datagen
A project rule for Minecraft Fabric 1.14.4 resources, such as item models, block models, recipes, and language files. It requires these files to be written as JSON in the source resources folders because that version does not include the newer data-generation system.
meta-quest-agentic-tools
Use Meta Quest Agentic Tools for Meta Quest and Horizon OS samples.
narrative-writing
A set of rules for writing and editing video-game narratives, connected to a narrative project. It requires the agent to load the project's writing context and story canon, which is the established set of story facts, before making changes.
meta-quest-agentic-tools
Use Meta Quest Agentic Tools for Meta Quest and Horizon OS samples.
visual-and-observational-rules
Defines the visual aspects of the game and how the player observes the world. This includes map color-coding, screen effects, and the overall simulation style.
