behavior-trees
Behavior tree design and implementation skill for game AI. Enables creation of behavior tree structures, custom nodes, decorators, composites, and integration with game engines for NPC and enemy AI systems.
npx skills add a5c-ai/babysitter --skill behavior-trees --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# Behavior Trees Skill Comprehensive behavior tree design and implementation for game AI systems, supporting multiple engines and frameworks. ## Overview This skill provides capabilities for designing and implementing behavior trees for game AI. It covers the creation of tree structures, custom nodes, blackboard systems, and integration with Unity, Unreal Engine, and Godot behavior tree implementations. ## Capabilities ### Tree Design - Design behavior tree structures from specifications - Create hierarchical AI behaviors - Balance between reactive and goal-oriented behaviors - Optimize tree execution for performance ### Node Types - **Composite Nodes**: Sequence, Selector, Parallel, Random - **Decorator Nodes**: Inverter, Repeater, Cooldown, Conditional - **Leaf Nodes**: Actions, Conditions, Services ### Blackboard System - Design blackboard schemas - Implement blackboard observers - Manage shared AI state - Handle blackboard key types ### Engine Integration - Unity: NodeCanvas, Behavior Designer, custom implementations - Unreal: Behavior Tree Editor, custom tasks and services - Godot: Beehave, LimboAI, custom implementations ### Debugging - Tree visualization - Node state trackin

What does the behavior-trees skill do?
Behavior tree design and implementation skill for game AI. Enables creation of behavior tree structures, custom nodes, decorators, composites, and integration with game engines for NPC and enemy AI systems.
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill behavior-trees --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
