A guide to using the LimboAI Godot add-on for behavior trees and hierarchical state machines—ways to organize how game characters decide and change actions—with a visual editor and shared data called a blackboard.

Use it to build characters that patrol, detect threats, fight, flee, or switch between complex states in Godot 4.6 and later.

It helps you choose and connect these AI structures, while making the add-on’s Godot version and GDScript, C++, and C# limitations clear.

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	$0.00041	$0.03467
Opus 5	$0.00020	$0.01733
Sonnet 5	$0.00008	$0.00693
Haiku 4.5	$0.00004	$0.00347

Security

Grade A, and why

limboai 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 11d 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.

LimboAI

Related skills: ai-navigation for movement the tasks drive, state-machine for core-engine FSM (when you don't need an addon), godot-brainstorming for choosing an AI approach.

Addon: LimboAI · version v1.8.0 · Godot 4.6+ (GDExtension) · MIT · source: https://github.com/limbonaut/limboai · written in C++ (GDExtension; engine-module build also available). GDExtension exposes GDScript; C# requires the module build (not GDExtension in v1.8.0), and the v1.8.0 module build targets Godot 4.7.

1. When to use LimboAI

Approach	Best for
Core-engine FSM (`state-machine` skill)	Simple agents, < 5 states, no addon
Beehave (GDScript addon)	Lightweight BT, GDScript-only projects
LimboAI	BT and HSM together, visual editor, C++ performance, C# support (module build)

Choose LimboAI when you need a behavior tree with a polished visual debugger, want to combine it with a hierarchical state machine (BTState bridges them), or need C++ task execution speed. Note: LimboAI requires Godot 4.6+ and is not usable on 4.3–4.5. For a simpler GDScript-only behavior tree, Beehave is a lighter alternative. For plain state machines without a BT, use the built-in state-machine skill instead.

2. Install & setup

GDExtension (recommended — no custom engine)

Godot AssetLib → search "LimboAI" → Download → Reload project.
Or download from GitHub Releases and place addons/limboai/ in res://addons/limboai/.
Enable the plugin: Project → Project Settings → Plugins → tick LimboAI.

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.

limboai is a skill published in the GitHub repository jame581/GodotPrompter (690 stars, last pushed 29d ago), licensed MIT. It adds 41 tokens to every session and 3,467 once invoked, about $0.0002 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.
