A Godot 4 support skill for building and automating 2D and 3D games with the open-source Godot game engine.

Use it for typed GDScript or C# systems, SceneTree and node architecture, physics, rendering backends, and headless continuous-integration exports.

It helps structure scenes and nodes, handle physics and signals, and automate exports and tests from the command line.

Token cost

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	$0.00026	$0.00792
Opus 5.5	$0.00010	$0.00317
Sonnet 5.5	$0.00005	$0.00158
Haiku 4.5	$0.00003	$0.00079

Security

Grade A, and why

godot 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.

Godot Engine 4.x Game Development AI Skill Guide (Claude)

Overview & Engine Architecture

Godot 4.3+ / 4.4 (pin in project.godot config/features) uses SceneTree, GDScript 2.0, optional C# .NET, renderers Forward+, Mobile, Compatibility (GL). Claude acts as Principal Game Developer: headless export CI, GUT tests, deterministic simulation, Dedicated server builds.

When to use / when not to

Use when: 2D/3D indie pipelines, tool-first games, lightweight server builds, scripted batch export.

Do not use when: AAA Nanite-scale content; console cert without export platform docs.

Operational Capabilities & Agent Directives

Static typing: GDScript @export, typed arrays, class_name — avoid cyclic class_name deps.
Determinism: Fixed Engine.time_scale in tests; seed RandomNumberGenerator with seed=hash; disable physics jitter tests unless Physics Interpolation configured consistently.
Headless CI: --headless --display-driver headless (platform-dependent); export requires export templates installed matching editor version.
Export presets: export_presets.cfg names are case-sensitive in CLI; run godot --headless --export-release "Windows Desktop" path.exe.
Web: COOP/COEP for threads; or single-threaded export preset — blank page otherwise.
Color/render: Forward+ vs Compatibility changes lighting; golden screenshots only on pinned renderer + same GPU driver class.

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.

Changes

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 is a skill published in the GitHub repository alivirgo/Major-AI-Skills (2 stars, last pushed yesterday), licensed MIT. It adds 26 tokens to every session and 792 once invoked, about $0.0001 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 2026-08-31.
