GodotPrompter is a free, open-source plugin that teaches AI coding agents Godot 4. 59 skills and 9 specialist agents cover architecture, state machines, physics, shaders, UI, multiplayer, web export and more, with GDScript and C# examples checked against Godot 4.3 to 4.7. The agent loads the right skill on demand, so it writes idiomatic Godot 4 code instead of guessing. Works with Claude Code, Copilot CLI, Cursor, Codex, OpenCode, Antigravity and Grok Build.
