Generate and maintain a playable HTML/JS prototype from feature specs. Builds a persistent browser-based game sandbox that grows across sprints, letting you test mechanics and UI flows before committing to Godot implementation.
Orchestrate the full game development workflow — Phase 0 design pipeline, sprint cycles, lifecycle gates. Reads workflow state to ensure correct sequencing across sessions. Run this before starting any game development work.
Generate a comprehensive Full Game Vision document capturing every mechanic, system, content layer, and feature across all lifecycle phases. Creates the master scope map that GDDs pull from.
Generate sprint-based implementation roadmaps with "Player can X" playable increments and per-agent breakdowns. Scales from prototype to production.
Generate detailed feature specifications with an optional idea refinement phase. Handles the full pipeline from vague idea to structured spec, using the project's feature spec template, GDD, and roadmap for context.
Generate creative, emotionally grounded game concepts through interactive constraint gathering. Uses uniqueness tests and personal resonance to avoid derivative ideas.

Generate game UI through a Figma Make round-trip: create art assets, compose an HTML mockup, push to Figma, let the user add interactivity in Make, pull the interactive prototype back, and implement it in Godot.
| Field | Value |
|---|---|
| Assigned Agent | Any (typically ui-dev or orchestrator) |
| Sprint Phase | Phase A or B (UI implementation) |
| Directory Scope | assets/ui/, scenes/ui/, scripts/ui/ |
| Required MCP Servers | Figma (plugin:figma:figma), Ludo (ludo) |
Users can trigger this skill by saying:
/figma-ui-pipelineThe skill accepts an optional argument describing the UI element to create:
/figma-ui-pipeline action bar for an RPG/figma-ui-pipeline main menu with animated title/figma-ui-pipeline inventory grid with item tooltipsIf no argument is provided, ask the user what UI element they want to create.
Phase 1: Asset Generation (Ludo MCP)
↓
Phase 2: HTML Mockup (local)
↓
Phase 3: Push to Figma (generate_figma_design)
↓
Phase 4: User edits in Figma Make (manual)
↓
Phase 5: Pull from Make (MCP resources)
↓
Phase 6: Implement in Godot (.tscn + .gd)
↓
Phase 7: Smoke Test
Generate visual assets for the UI element using Ludo MCP.
Before generating, determine what images are needed:
Load the Ludo tools:
ToolSearch: query="+ludo create"
For each asset, use mcp__ludo__createImage:
mcp__ludo__createImage:
prompt: "[descriptive prompt for the asset]"
style: "[match project art direction if docs/art-direction.md exists]"
imageType: "game_asset"
genre: "[game genre]"
aspectRatio: "1:1" (for icons/portraits) or "16:9" (for backgrounds)
Style consistency: If docs/art-direction.md exists, read it and use the established style keywords in every prompt. If style anchors exist in assets/references/, use mcp__ludo__generateWithStyle instead.
CRITICAL: Remote URLs will NOT load reliably in the Figma capture. Always download locally.
cd assets/ui/[element-name]/
curl -sL "[ludo-url]" -o [name].webp
Save all generated images to assets/ui/[element-name]/.
Create a brief manifest file for reference:
assets/ui/[element-name]/assets.md
Contents:
# [Element Name] Assets
Generated via Ludo MCP on [date]
| File | Description | Ludo URL |
|------|-------------|----------|
| sword.webp | Sword slash ability icon | https://storage... |
Build a static HTML page at 1920x1080 that composites the generated images into the UI layout.
Save to: assets/ui/[element-name]/mockup.html
Required elements in the HTML:
<head>):<script src="https://mcp.figma.com/mcp/html-to-design/capture.js" async></script>
body {
width: 1920px;
height: 1080px;
overflow: hidden;
position: relative;
}
<img src="sword.webp" alt="Sword Slash">
For maximum reliability with Figma capture, embed images as base64 data URIs. This eliminates any image loading timing issues.
Generate the embedded version using Python:
python3 -c "
import base64
with open('mockup.html', 'r') as f:
html = f.read()
for name in ['image1', 'image2', ...]:
with open(f'{name}.webp', 'rb') as f:
b64 = base64.b64encode(f.read()).decode('ascii')
html = html.replace(f'{name}.webp', f'data:image/webp;base64,{b64}')
with open('mockup-embedded.html', 'w') as f:
f.write(html)
"
Save as: assets/ui/[element-name]/mockup-embedded.html
When building the mockup, follow the project's visual style:
docs/design-bible.md for color palette and tone (if it exists):hover as visual reference (won't transfer to Figma)# Check if port is free
lsof -i :8080
# Start server from the asset directory
cd assets/ui/[element-name]/
npx http-server . -p 8080 --cors
curl -s -o /dev/null -w "%{http_code}" http://localhost:8080/mockup-embedded.html
# Should return 200
Load the Figma tool:
ToolSearch: query="select:mcp__plugin_figma_figma__generate_figma_design"
Create a new Figma file:
mcp__plugin_figma_figma__generate_figma_design:
outputMode: "newFile"
fileName: "[Element Name] - Game UI"
This returns a capture ID and instructions.
CRITICAL: Use figmadelay=5000 or higher to ensure images load before capture.
open "http://localhost:8080/mockup-embedded.html#figmacapture=[CAPTURE_ID]&figmaendpoint=[ENDPOINT]&figmadelay=5000"
Wait 15 seconds, then poll:
mcp__plugin_figma_figma__generate_figma_design:
captureId: "[CAPTURE_ID]"
open "[FIGMA_CLAIM_URL]"
Tell the user:
The UI mockup has been pushed to Figma: [URL]
Next steps:
1. Open the Figma file and verify the layout looks correct
2. Pass it to Figma Make to add interactivity
3. In Make, add animations (hover effects, transitions, state changes)
4. When done, share the Make URL with me and I'll implement it in Godot
Images missing in Figma:
figmadelay to 7000-10000msCapture fails/errors:
Layout wrong:
This phase is done by the user. They will:
While waiting, you can:
When the user shares the Make URL, proceed to Phase 5.
From a Make URL like:
https://www.figma.com/make/[FILE_KEY]/[NAME]?...
Extract [FILE_KEY].
Load the Figma tool:
ToolSearch: query="select:mcp__plugin_figma_figma__get_design_context"
mcp__plugin_figma_figma__get_design_context:
fileKey: "[FILE_KEY]"
nodeId: ""
clientLanguages: "gdscript"
clientFrameworks: "godot"
This returns a list of resource links. The key files are:
src/app/App.tsx — Primary file. Contains all interactive behavior.src/imports/[ComponentName].tsx — Auto-generated static layout from Figma Design.IMPORTANT: The MCP server name is plugin:figma:figma (with colons, not underscores).
ReadMcpResourceTool:
server: "plugin:figma:figma"
uri: "file://figma/make/source/[FILE_KEY]/src/app/App.tsx"
Also fetch any custom components imported by App.tsx. Skip the generic components/ui/ files (those are shadcn defaults).
Read the App.tsx and extract a behavior map. Look for:
| React/Framer Motion Pattern | What It Means |
|---|---|
whileHover={{ scale: 1.05 }} | Hover: scale to 1.05 |
whileTap={{ scale: 0.95 }} | Press: scale to 0.95 |
animate={{ opacity: [0.3, 0.7, 0.3] }} | Looping opacity pulse |
transition={{ duration: 2, repeat: Infinity }} | 2-second infinite loop |
initial={{ opacity: 0, y: -50 }} | Entrance animation (fade + slide) |
useState / useEffect | State management / side effects |
onClick handler | Click behavior |
onMouseEnter / onMouseLeave | Hover enter/exit |
CSS transition: all 0.2s ease | Smooth property transitions |
CSS box-shadow: 0 0 Npx color | Glow effect (use shader or modulate in Godot) |
CSS filter: grayscale(1) | Desaturated icon (use modulate in Godot) |
Document the behavior map before implementing.
Create a minimal .tscn file with just the root Control node and script reference:
Scene: scenes/ui/[element_name].tscn
Script: scripts/ui/[element_name].gd
Use this mapping to convert Make behaviors to Godot:
| Make (React/Framer Motion) | Godot Equivalent |
|---|---|
<div> container | Control / Panel / ColorRect |
<img src="..."> | TextureRect with loaded texture |
<p> / <span> text | Label / RichTextLabel |
<button> | Button / Panel with gui_input signal |
whileHover scale | mouse_entered/mouse_exited signals → Tween scale |
whileTap scale | gui_input (button_pressed) → Tween scale |
animate looping | create_tween().set_loops() |
transition.duration | Tween duration parameter |
transition.ease: "easeOut" | Tween.EASE_OUT |
transition.delay | tween.tween_interval(delay) before animation |
initial → animate | Entrance tween in _ready() |
useState | GDScript var member variables |
useEffect with interval | _process(delta) or Timer node |
onClick | gui_input signal or pressed signal |
CSS background: linear-gradient(...) | StyleBoxFlat with bg_color or gradient shader |
CSS border: 2px solid color | StyleBoxFlat with border_color and border_width |
CSS border-radius: Npx | StyleBoxFlat with corner_radius |
CSS box-shadow: 0 0 Npx color | Glow shader (radial_glow.gdshader) or CanvasItemMaterial(BLEND_MODE_ADD) |
CSS opacity: N | modulate.a = N or self_modulate.a = N |
CSS transform: translateY(-4px) | Tween position.y |
CSS filter: grayscale(1) | modulate = Color(0.5, 0.5, 0.5, 0.4) |
toLocaleString() (number formatting) | Custom _format_number() function |
For CSS box-shadow glow effects on dark backgrounds, use the project's radial glow shader:
var glow_shader: Shader = load("res://resources/shaders/radial_glow.gdshader")
If the shader doesn't exist, create it:
shader_type canvas_item;
uniform vec4 glow_color : source_color = vec4(0.0, 1.0, 0.533, 0.4);
uniform float softness : hint_range(0.01, 1.0) = 0.5;
void fragment() {
float dist = distance(UV, vec2(0.5));
float alpha = smoothstep(0.5, 0.5 - softness * 0.5, dist);
COLOR = vec4(glow_color.rgb, glow_color.a * alpha);
}
For sweep/flash effects (button press flash), use:
shader_type canvas_item;
uniform float sweep_position : hint_range(-0.5, 1.5) = -0.5;
uniform float sweep_width : hint_range(0.05, 0.5) = 0.15;
uniform float max_opacity : hint_range(0.0, 1.0) = 0.3;
void fragment() {
float dist = abs(UV.x - sweep_position);
float alpha = smoothstep(sweep_width, 0.0, dist) * max_opacity;
COLOR = vec4(1.0, 1.0, 1.0, alpha);
}
Structure the GDScript to match the Make file's component architecture:
extends Control
# --- Constants (from Make file's data model) ---
const ITEM_DATA: Array[Dictionary] = [...]
# --- State (from Make file's useState) ---
var _selected_item: int = 0
var _hovered_item: int = -1
# --- UI References (built in _ready or from scene tree) ---
var _slots: Dictionary = {}
func _ready() -> void:
_load_textures()
_build_ui()
func _process(delta: float) -> void:
# Tick any timers (cooldowns, animations)
pass
func _input(event: InputEvent) -> void:
# Keyboard shortcuts (from Make file's useEffect keydown handler)
pass
assets/ui/[element-name]/mouse_entered/mouse_exited)gui_input / pressed)set_loops())_ready() (if applicable)mouse_filter settings are correct (IGNORE on decorative elements)[godot_path] --headless --editor --quit --path "[project_path]" 2>&1
[godot_path] --headless --quit --path "[project_path]" 2>&1
If clean:
Smoke test passed. The [element name] scene is ready at:
- Scene: scenes/ui/[element_name].tscn
- Script: scripts/ui/[element_name].gd
To test: open the scene in Godot and run it (F6).
If errors: diagnose, fix, and re-run until clean.
