How we review

Extended accessThe tool runs code or makes network calls and only reads external data.

What it does

A repository of thirteen skills the author assembled for personal game development work. The architecture skill helps with requirements and project logic, `game-design-review` critiques concepts, mechanics, levels and balance, `game-balance-analysis` builds first-pass numbers, simulations and parameter sweeps. A separate `game-agent-toolkit` leads pre-production in milestones. The other skills deal with assets: rules for game image generation, generation through OpenAI and OpenRouter, ImageMagick processing, local background removal with Lucida, slicing video frames and procedural Three.js 3D models exported as GLB, glTF, OBJ and STL.

Who it is for. Indie game developers and technical designers who work with an agent on concepts, balance and game assets.

Good fit when

  • A game concept needs review by mechanics, levels and social features.
  • You need starting balance numbers and a simulation run.
  • A prototype needs sprites, transparent backgrounds and frame slicing.
  • A procedural 3D model is exported as GLB for a game engine.

Not a fit when

  • You need ready engine plugins for Unity or Unreal.
  • You expect a supported product with versions and releases: this is a personal collection.
  • Images cannot be sent to external generation services.

Example request

Review my game concept with the `game-design-review` skill and flag weak spots in mechanics and balance.

Limitations

The repository is personal: GitHub metadata shows no license, the README has no install guide, and skills are copied by hand into the agent directory. Skills that generate through OpenAI and OpenRouter need your own keys and spend money on calls. `lucida-remove-background` and ImageMagick need local programs. The `animation-shader` skill has a one-line description, so judge it by its `SKILL.md`. Some skills are adapted from other projects, for example `gpt-image` from `gpt_image_2_skill`: check source licenses before team use.

How to disable. Delete the skill folders from the agent skills directory. Revoke the OpenAI and OpenRouter keys at the provider if you set them.

FAQ

Which skills are there?

Thirteen: game architecture, design review, balance, image generation rules, `gpt-image`, OpenRouter for images and video, ImageMagick, background removal, Three.js 3D, shaders and frame slicing.

What is game-agent-toolkit?

A milestone-driven game pre-production workflow. Implementation can continue with OpenSpec or Superpowers.

Which 3D formats are supported?

The Three.js skill validates and exports GLB, glTF, OBJ and STL.

How do I install the skills?

The README gives no command. Copy the folders you need from `skills/` into your agent skills directory.

Is there a Russian description?

No, the README is in English and Chinese.
