Design NPC and enemy decision-making with finite state machines, behavior trees, steering behaviors, and A* pathfinding — engine-neutral algorithms that pair with the detected engine's navigation API. Use when building enemy AI, an FSM or behavior tree, steering/flocking, or pathfinding, or when the user mentions state machine, behavior tree, blackboard, A*, navmesh, seek, or patrol/chase.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Game AI: decisions, steering, and pathfinding Build believable NPC behavior from three separable layers: **decide** (what to do), **steer** (how to move there), and **path** (how to route around the map). Keep them decoupled — a behavior tree picks a target, the pathfinder produces waypoints, steering follows them. This skill teaches the engine-neutral algorithms; bind them to your engine via the related skills below. ## When to use - Use when implementing enemy/NPC logic: patrols, chase/flee, guard states, group movement, or "find a path to the player". - Use to choose between an **FSM** (few clear states), a **behavior tree** (many reactive behaviors with priorities), or **steering** (smooth local movement). - Use when integrating pathfinding: A* on a grid/graph, or driving an engine navmesh agent. **When *not* to use:** for the engine's concrete navmesh/agent API and baking, use `unity-navmesh`, `unreal-behavior-trees`, or Godot's `NavigationAgent2D/3D` (see that engine skill). For movement/collision feel, use `physics-tuning`. For spawning waves along lanes, see the `tower-defense` genre skill. ## Core workflow …

How to install
mdr add gamedev-skills/awesome-gamedev-agent-skills/game-ai@sha256:ef23a6440743b358The line at the top of this page pins the label git:20260808.3727d02, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
