Godot Prompter

Your AI coding agent doesn't know Godot 4 exists.

Ask Claude Code, Cursor, or Copilot for Godot help and you'll often get yield(), Physics2DDirectBodyState, or other Godot 3 syntax that hasn't worked in years, because that's what dominates the training data. GodotPrompter fixes this by giving agents structured knowledge specific to Godot 4.3+, loaded before they write a line of code.

What it is

GodotPrompter is a free, open-source plugin that adds 51 skills: focused markdown files, each under a strict 16 KB budget, covering everything from project setup to multiplayer sync. When you ask your agent to "add a state machine" or "set up a coyote-time jump," it loads the matching skill and follows Godot-specific patterns instead of guessing.

How it works

1. Design: brainstorm a feature; the agent asks clarifying questions and proposes a scene tree before writing anything
2. Implement: the matching domain skill loads per task, covering player controllers, inventory, shaders, multiplayer, and 40+ more
3. Review: ask for a code review and the agent checks your work against Godot-specific checklists, not generic advice

It also ships 9 specialized agents (architect, implementer, code reviewer, shader author, performance profiler, animator, C# engineer, UI designer, tools engineer) that orchestrate the skills for you.

What's covered

Project setup and architecture, physics and 2D/3D/XR, thirteen gameplay systems (player controllers, inventory, dialogue, save/load, AI navigation, and more), UI/UX, multiplayer, shaders and VFX, build and deploy, GDScript and C# (kept in parity, so both get equal treatment rather than one being a bolted-on afterthought), native extensions, multithreading, and third-party addons like LimboAI and Beehave. Everything targets Godot 4.3+, with newer 4.5/4.6 features included as annotated additions.

Works with the agent you already use

Claude Code (primary), Cursor, Grok Build, Gemini CLI, GitHub Copilot CLI, Codex, OpenCode, and Antigravity.

Quick start (Claude Code)

claude plugins marketplace add jame581/skillsmith
claude plugins install godot-prompter@skillsmith

Setup for every other platform is in the GitHub README; most are a single install command.

Built to stay accurate

Every skill runs through an automated validator on every release: broken cross-references, missing GDScript/C# parity, and token-budget overruns all fail CI before a release ships. Current baseline: 0 errors across all 51 skills.
