Build, integrate, audit, or refactor rigged monsters for Three.js and web action games. Use for monster asset contracts, procedural or imported creature rigs, semantic joints and sockets, hurtboxes and attack volumes, combat animation states, enemy-runtime adapters, LODs, deterministic review fixtures, and validating that every monster follows one shared system.

# Build Game Monster System

Build monsters as gameplay-compatible runtime assets, not decorative meshes.

## Establish the contract

Read [references/monster-contract.md](references/monster-contract.md) before implementation or audit. Check the real game content model, combat events, enemy state machine, collision API, camera distance, and asset loader before extending the contract.

Use related skills when applicable:

- Use `img2threejs` for image-driven procedural reconstruction and its staged visual gates.
- Use `build-hybrid-game-assets` to choose procedural versus imported representation and record provenance/budgets.
- Use `tune-enemy-ai` for perception, intent, movement, and behavior transitions.
- Use `design-action-combat` for startup/active/recovery timing and authoritative contact.
