Unreal Engine 5 (UE 5.8) NPC AI with Behavior Trees, Blackboards, EQS and StateTree: decorators with Observer Aborts, C++ BTTask nodes and running trees from an AIController. Use for UE enemy AI, BT_, BB_ or EQS_ assets, "my AI just stands there" or "MoveTo fails". Not for engine-neutral BT or utility code (`ai-behavior-trees-utility-ai`) or choosing FSM vs BT (`game-ai`).

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'unreal-behavior-trees' ] || [ -L ~/.agents/skills/'unreal-behavior-trees' ]; then echo 'A skill folder named unreal-behavior-trees already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/gamedev-skills/awesome-gamedev-agent-skills' "$d" && git -C "$d" checkout --quiet 'c6ca6c41c839b68319ffc08430b99ab768debc32' -- 'skills/unreal/unreal-behavior-trees' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/unreal/unreal-behavior-trees' ~/.agents/skills/'unreal-behavior-trees' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'unreal-behavior-trees' ~/.claude/skills/'unreal-behavior-trees' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
