awesome-gamedev-agent-skills is a collection of 73 instruction files that give AI coding agents specialized guidance for game development with engines and frameworks such as Godot, Unity, Unreal, and Phaser. It helps agents choose relevant engine and task guidance while building games. The catalogue entries are the collection's skills and plugins for agents including Claude Code, Cursor, Codex, and Gemini CLI.
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 | $0.00086 | $0.01413 |
| Opus 5.5 | $0.00034 | $0.00565 |
| Sonnet 5.5 | $0.00017 | $0.00283 |
| Haiku 4.5 | $0.00009 | $0.00141 |
Grade A, and why
unreal-blueprints 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 2d 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unreal Blueprints (Visual Scripting)
Structure gameplay logic in Unreal Engine 5 Blueprints: pick the right graph, expose data cleanly, and choose a communication method that doesn't create hard-reference spaghetti. Targets UE 5.8. (Blueprints are node graphs; the snippets below describe node flows.)
When to use
- Use when authoring a Blueprint Class, wiring the Event Graph (BeginPlay/Tick/overlap), using the Construction Script, creating variables/functions/macros, or choosing how two Blueprints communicate (Cast, Interface, or Event Dispatcher).
- Use when the project has
*.uprojectand Blueprint*.uassetfiles, and the user works visually rather than in C++.
When not to use: performance-critical systems, large data structures, or anything that
benefits from source control diffs and unit tests → unreal-cpp-gameplay. Player input
mapping → unreal-enhanced-input. AI logic → unreal-behavior-trees.
Core workflow
- Choose the Blueprint type. A Blueprint Class (derived from Actor/Pawn/Character/ ActorComponent) defines a reusable object. The Level Blueprint is a per-level graph for level-specific scripting only — don't put reusable logic there.
- Use the Construction Script for editor-time setup (procedural placement, configuring components from variables) — it runs when the actor is placed or edited, not during play.
- Use the Event Graph for runtime logic.
Event BeginPlayfor init, input/overlap events for reactions. AvoidEvent Tickunless you truly need per-frame work. - Expose data with variables; click the eye icon to make a variable Instance Editable, and group related ones with categories. Mark pure functions (no exec pin) for getters.
- Pick a communication method by coupling (see Patterns): direct Cast for things you own, Blueprint Interface to call across types without hard references, Event Dispatcher to broadcast one-to-many.
- Verify with the Blueprint debugger: drop breakpoints on nodes, watch variable values, and use Print String to confirm execution paths during Play In Editor (PIE).
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.

unreal-blueprints is a skill published in the GitHub repository gamedev-skills/awesome-gamedev-agent-skills (4,867 stars, last pushed 3d ago), licensed Apache-2.0. It adds 86 tokens to every session and 1,413 once invoked, about $0.0003 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.
Other skills, from other repositories
editor-session-quit
Save and quit an editor that a CLI session started (unity-mcp-cli exec, open --headless). Needs the session lease nonce; an editor the user opened is never closed. Used by unity-mcp-cli close.
screenshot-game-view
Capture a screenshot of the Unity Editor's Game View by reading its internal render texture directly. Image size matches the current Game View resolution; the tool corrects Y-flip on DirectX / Metal so the output is always upright. Requires an open Game View window.
dialogue-manager
Use when using the Dialogue Manager addon — .dialogue files with titles, responses, conditions and mutations, runtime balloons, and C# support.
event-bus
Use when implementing decoupled communication between nodes — global EventBus autoload with typed signals.
physics-system
Use when working with physics bodies, collision shapes, raycasting, areas, rigid bodies, ragdolls, soft bodies, Jolt physics, and physics interpolation in Godot 4.3+.
biome-detail-tuning
Configure and tune Unity Terrain detail (grass/flower/fern) placement for MapGenerator biomes using prefabs and noise-driven clustering. Covers the full workflow from prefab selection through noise parameter tuning to external audit verification and performance optimization. Use when: setting up detail for any biome…
