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 | $0.00104 | $0.04286 |
| Opus 5 | $0.00052 | $0.02143 |
| Sonnet 5 | $0.00021 | $0.00857 |
| Haiku 4.5 | $0.00010 | $0.00429 |
Grade A, and why
ue-gameplay-framework 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 — 439 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UE Gameplay Framework
You are an expert in Unreal Engine's gameplay framework architecture.
Context Check
Read .agents/ue-project-context.md before proceeding. The game type (single player, co-op, competitive multiplayer, dedicated vs listen server) determines which classes to subclass and which replication patterns apply. Resolve: single-player or multiplayer? Dedicated or listen server? What are you implementing?
Class Responsibility Map
Each class exists on specific machines for specific reasons. Getting this wrong is the primary source of multiplayer bugs.
AGameModeBase / AGameMode — Server Only
Exists on: Server and standalone only. Never instantiated on clients.
Why server-only: GameMode is the authoritative referee. It decides who joins, when the match starts, where players spawn, and what the win conditions are. Client execution would allow cheating via local state manipulation.
AGameMode adds the full match-state machine (EnteringMap → WaitingToStart → InProgress → WaitingPostMatch → LeavingMap; Aborted on failure) with ReadyToStartMatch and ReadyToEndMatch hooks. Use AGameModeBase for lobby/simple games, AGameMode for match flow.
Key API from source (GameModeBase.h):
// Class assignments — set in constructor
TSubclassOf<APawn> DefaultPawnClass;
TSubclassOf<AGameStateBase> GameStateClass;
TSubclassOf<APlayerController> PlayerControllerClass;
TSubclassOf<APlayerState> PlayerStateClass;
TSubclassOf<AHUD> HUDClass;

virtual void PostLogin(APlayerController* NewPlayer); // first safe point for RPCs (DispatchPostLogin deprecated 5.6 — override PostLogin directly)
virtual void Logout(AController* Exiting);
virtual void HandleStartingNewPlayer(APlayerController* NewPlayer);

What ships with it
1 file 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-gameplay-framework is a skill published in the GitHub repository quodsoler/unreal-engine-skills (335 stars, last pushed 6mo ago), licensed MIT. It adds 104 tokens to every session and 4,286 once invoked, about $0.0005 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.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
