Design, implement, review, and migrate XState v5 state machines and statecharts in TypeScript using modern v5 patterns. Use this whenever the user mentions XState, actors, state machines, statecharts, guards, transitions, workflows, or Stately, or is modeling non-trivial UI/app/process logic in a codebase that uses XState. Prefer a short machine sketch before code when requirements are fuzzy. If the problem is too simple for a state machine, say so and recommend @xstate/store instead.

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'xstate-v5' ] || [ -L ~/.agents/skills/'xstate-v5' ]; then echo 'A skill folder named xstate-v5 already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/AkaraChen/angel-engine' "$d" && git -C "$d" checkout --quiet '48a57981043dbb2c534a27f410715a205f50bcfb' -- '.agents/skills/xstate-v5' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/xstate-v5' ~/.agents/skills/'xstate-v5' && 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/'xstate-v5' ~/.claude/skills/'xstate-v5' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
