9 AI Agent Skills for Three.js Game Development Released

Developer Majid Manzarpour has released a bundle of 9 Three.js Game Skills that can be used in Codex and Claude Code runners. These skills can be installed and used by copying files into the existing runner's skill directory without requiring specific models or API keys.

Key Features and Structure

This skill set provides scaffolding based on Vite, TypeScript, and Three.js, including deterministic test hooks and seed-fixed random numbers. threejs-game-director serves as the entry point, distributing tasks according to the request scope. The basic structure consists of 1 leader and 2 workers, with clearly defined file ownership and I/O contracts.

The 9 provided skills are as follows:

• director: Responsible for routing and verification
• gameplay-systems, aaa-graphics-builder, ui-designer: Game logic, graphics, and UI development
• debug-profiler, qa-release: Debugging and release management
• 3d-generator, image-generator, audio-generator: Asset generation using Tripo, Gemini, and ElevenLabs APIs (core skills are free; external asset generation requires the respective API keys)

Visual Quality Scorecard and Verification Mechanism

The core differentiator of this project is objective verification through a visual quality scorecard consisting of 10 items (0-3 points). It requires measured evidence such as screenshots, pixel metrics, and bot play records to determine if the agent-generated output meets the standards.

• Premium Standard: All items ≥ 2 points, average ≥ 2.3 points
• Showcase Standard: All items ≥ 2 points, ≥ 6 items at 3 points, average ≥ 2.7 points
• Automatic Failure Conditions: Unplayable, use of unpolished basic shapes, abuse of rectangular statistics card HUDs, absence of renderer diagnostics, etc.

Additionally, canvas metrics establish falsification criteria. If color entropy is less than 3.0 bits or the dominant color ratio exceeds 0.6, the screen is considered flat and scores are limited. Scores for lighting or geometry items are also limited if edge density or luminance contrast falls below standards.

Installation and Limitations

Installation is possible via the command npx skills add majidmanzarpour/threejs-game-skills and follows the MIT license. However, engines other than Three.js/browser canvas are not supported, and background execution or asynchronous processing depends on the runner's own capabilities. Mock responses in helper tests are not accepted as evidence of visual quality improvement.
