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 | $0.00061 | $0.01817 |
| Opus 5 | $0.00030 | $0.00908 |
| Sonnet 5 | $0.00012 | $0.00363 |
| Haiku 4.5 | $0.00006 | $0.00182 |
Grade A, and why
godot-game-dev 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 5d 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 — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Godot — AI Game Dev runbook
This skill teaches your AI coding assistant (Claude Code or Codex CLI) to drive Godot fully
automatically through the godot-cli npm package. The goal: take the user from nothing to a
running Godot Editor that is connected to ai-game.dev so the AI can
build the game for them.
Every command runs via npx so nothing needs to be installed globally:
npx -y godot-cli@latest <command> [args]
Prerequisites (check first)
- Node.js 18+ —
node --version. - Godot 4.x (.NET / Mono build) installed — the Godot-MCP addon is C#, so use the Mono editor, not the plain build.
- .NET SDK installed — Godot C# projects require it to build (
dotnet --version). - A free ai-game.dev account — the
loginstep authorizes the project against the cloud. - Windows / macOS / Linux with a real desktop session (the editor opens a window).
The automatic end-to-end sequence
Run these in order. Do not skip the ordering rule around close → login → open.
1. Create the project (fresh start only)
Skip this step if the user already has a project — go straight to step 2 pointing at it.
npx -y godot-cli@latest create-project "C:/Games/MyGame" --dotnet --name MyGame
create-project <path>scaffolds a new Godot 4.x project at<path>.--dotnetmakes it a C# (.NET) project (required for the Godot-MCP addon).--name <Name>sets the project name.
Verify: the <path> now contains project.godot and a .csproj.
2. Install the Godot-MCP addon
npx -y godot-cli@latest install-plugin "C:/Games/MyGame"
Installs the godot_mcp addon, adds the required NuGet pins to the project's .csproj, and
enables the plugin. Verify: an addons/godot_mcp/ folder exists and the plugin is listed as
enabled in project.godot.
3. Close the editor before logging in
npx -y godot-cli@latest close "C:/Games/MyGame"
# add --force if the editor won't exit cleanly
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.

godot-game-dev is a skill published in the GitHub repository IvanMurzak/ai-game-dev-plugin (3 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 61 tokens to every session and 1,817 once invoked, about $0.0003 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.
