DSH Game Studio: Turn a Sentence into a Playable Game in the DeepSeek Harness Sidebar

DSH Game Studio is a DeepSeek Harness plugin maintained by ZSeven-W, packaged as `@zseven-w/dsh-game-studio` version `0.1.0-rc.2` under the MIT license. Describe a mini-game in a single sentence, and the agent generates a playable game from 2D top-down or 3D voxel templates, with auto-playtest confirmation and real-time sidebar preview. Subsequently, OpenAI or Codex can generate numbered candidate images for art slots, displaying an approval card before spending and enabling art replacement by number. Every change is saved as a version for rollback, and the final output is a single-file offline HTML, supporting local network temporary links for testing. The plugin provides 10 agent tools (create / build / playtest / generate_asset / apply_asset / revert_asset / versions / restore_version / export / share), running games in a sandbox iframe where CSP blocks internet access. Installation requires `dsh plugin --profile web add @zseven-w/dsh-game-studio@latest`, with DSH 0.2.1+ and Node.js 24.11+ required, along with Chrome or Edge for auto-playtest. It is suitable for lightweight prototyping verification but not for serious game projects. The plugin runs with the current DSH process permissions; one should read the source code and verify the license before installing.
