What you end up with
Your agent stops writing Godot 3 code in your Godot 4 project.
What you get
- Ten-row trap table
- The headless check command
- Rules file lines
Who it is for
Anyone whose coding agent keeps writing yield, KinematicBody2D or export var in Godot 4.
Works with
Solid chips: the agent is named in this listing's own tools list. Dashed chip: Plain Markdown, so it also pastes into other agents such as Grok Bot, Hermes, OpenClaw or Muse. We list those as compatible by format only, not as tested.
Tools needed
Cost to run: Free.
Time to result: Five minutes to install
Sample prompts, free to use
Scan every .gd file for the Godot 3 patterns in docs/godot-traps.md. List each with file and line. Fix them all and rerun the headless check.
Run it once on any project an agent has touched.

# Godot 4 trap table for coding agents (free sample) A free sample from Engine Agent Kits by PaperChaseWebb. Works with Claude Code, Codex, Cursor or any coding agent working in a Godot 4 project. Coding agents mix Godot 3 and Godot 4 because both are in their training data. The errors look random until you know the pattern. Put this table in your repo and point your rules file at it. ## Ten traps agents hit most | Godot 3 habit | Godot 4 form | |---|---| | KinematicBody2D | CharacterBody2D | | Spatial | Node3D | | move_and_slide(velocity, Vector2.UP) | set velocity, then move_and_slide() with no arguments | | yield(obj, "signal") | await obj.signal | | export var speed = 200 | @export var speed: float = 200.0 |
