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 | $0.00149 | $0.01441 |
| Opus 5 | $0.00075 | $0.00720 |
| Sonnet 5 | $0.00030 | $0.00288 |
| Haiku 4.5 | $0.00015 | $0.00144 |
Grade A, and why
unreal-gas 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 12d 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unreal Engine Gameplay Ability System (GAS) -- C++ Guide
Official Documentation (always consult for latest details)
These are the authoritative sources. Reference them for up-to-date API details, as GAS evolves across engine versions:
The community docs by tranek are the most comprehensive single resource for GAS. They cover advanced topics (prediction internals, optimization, replication modes, pitfalls) that Epic's official docs do not. Always check them for edge cases and production patterns.
The Lyra Sample Project is Epic's recommended working reference implementation for GAS.
Plugin Setup
- Enable Gameplay Abilities plugin in the editor
- Add to
Build.cs:PublicDependencyModuleNames.AddRange(new string[] { "GameplayAbilities", "GameplayTags", "GameplayTasks" }); - UE 5.2 and earlier: call
UAbilitySystemGlobals::Get().InitGlobalData()in your AssetManager or GameInstance. UE 5.3+ does this automatically.
What ships with it
4 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.

unreal-gas is a skill published in the GitHub repository maystudios/claude-skills (22 stars, last pushed 27d ago), licensed MIT. It adds 149 tokens to every session and 1,441 once invoked, about $0.0007 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.
