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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00164 | $0.07392 |
| Opus 5.5 | $0.00066 | $0.02957 |
| Sonnet 5.5 | $0.00033 | $0.01478 |
| Haiku 4.5 | $0.00016 | $0.00739 |
Grade A, and why
ue-actor-component-architecture 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 1mo 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 — 476 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UE Actor-Component Architecture
Target engine: UE 5.8. APIs below are verified against the 5.8 headers; older forms are listed under "Deprecated — do not use".
Build actors out of components: lifecycle hooks in the right order, spawning (immediate, deferred, pooled), component creation and attachment, ticking, and C++ interfaces. Everything here is in the Engine module (GameFramework/Actor.h, Components/ActorComponent.h, Components/SceneComponent.h, Engine/World.h) on top of CoreUObject; a game module's Build.cs needs "Core", "CoreUObject", "Engine".
Context
Read .agents/ue-project-context.md if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.
Identify the area from the request and the codebase. Ask only when two plausible readings would produce different code.

| Creating, attaching, activating components | Component System |
| Overriding component hooks (OnRegister, InitializeComponent, TickComponent) | Component Lifecycle Hooks |
| SpawnActor, deferred spawn, pooling | Spawning |

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ue-actor-component-architecture is a skill published in the GitHub repository quodsoler/unreal-engine-skills (439 stars, last pushed 1mo ago), licensed MIT. It adds 164 tokens to every session and 7,392 once invoked, about $0.0007 per session on Opus 5.5. 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.
