Workflow

When this skill triggers, follow these steps in order.

Step 1 — Capture the game description

Ask the user to describe their game in plain English. Good descriptions include:

What the player controls and how (keyboard, mouse)
What the objective is (survive, collect, reach a goal)
What ends the game or increases the score
Any enemies, obstacles, or power-ups

Example: "A game where you move a player left and right to dodge blocks falling from the top. Score goes up the longer you survive; getting hit ends the game."

If the user is unsure, suggest the dodge-blocks starter from examples/input.md.

Step 2 — Run the engine

With cwd set to the skill root (skills/codewisp-game-builder/), run:

node scripts/gen-game.mjs <description-file> <output-html-file>

Or pipe the description directly:

echo "Your game description here" | node scripts/gen-game.mjs - output/index.html

The engine writes a single self-contained index.html that:

Loads kaplay via CDN (https://unpkg.com/kaplay@3001/dist/kaplay.js)
Initialises the game with kaplay(...)
Defines scenes with scene(...) (menu, game, game-over)
Spawns game objects matching the description
Runs a main loop via onUpdate(...) with movement, scoring, and collision
Handles keyboard input via onKeyDown(...)

Step 3 — Tell the user how to play

After the file is written, instruct the user:

Open <output-html-file> in any browser (double-click or drag into Chrome/Firefox/Safari). No server, no build step required.

Step 4 — Iterate

Ask whether the user wants to change the game. Common refinements:

Add a high-score tracker
Increase difficulty over time (faster blocks, more blocks)
Add power-ups or lives
Change the art style (colours, shapes, sizes)

Update the description and rerun Step 2 to regenerate. The file is fully overwritten each run.

Example

See examples/input.md for the dodge-blocks starter description and examples/output/index.html for the generated game.

Run the example yourself:

cd skills/codewisp-game-builder
bash examples/run.sh

The script generates examples/output/index.html and writes a verification report to examples/output.md.
