Claude Code Game Kit is a free, MIT-licensed starter kit from GitHub user Er2oneousbit that sets up a new or existing game project so Anthropic's Claude Code coding agent can work on it in a predictable way. According to the project's README, a beginner opens the kit folder in VS Code or the Claude desktop app, starts Claude Code and types "Start": Claude asks about the game, writes a one-page game plan with the user, then scaffolds the project. A Python script does the same by hand.
Every project gets one command set (check, test, smoke, build, run and more) that behaves the same on each engine, so the agent runs known commands instead of guessing build flags. The README lists 23 slash-command skills, 5 subagents (such as a code reviewer and a playtest analyst), 24 short how-to documents, permission rules that block reading secrets, and optional helpers for local or paid AI art and audio.
The README names nine engine targets: Godot 4, Phaser and Three.js browser games, C++ with SDL, Unity 6, Unreal Engine 5, Bevy, LÖVE and RPG Maker MZ, the last an untested proof of concept. The repository also holds 10 small example games, each with a HOW_IT_WAS_MADE write-up that includes what went wrong. The kit is free; Claude Code access is separate. It first went public on October 27, 2026 and was at version 0.14.2 on November 6, 2026, per its changelog. AIGamer hasn't tested it.
Limitation: Most testing was done on Windows 11, and the RPG Maker MZ support has never been run in the engine, per the README's own test table
