Who it is forA generative artist preparing a full edition who wants to review many seeds at once and then export individual files.

The problemChecking an edition one hash at a time misses how the pieces look together, and exporting files by hand is tedious.

The outcomeA grid image showing many seeds on one sheet, plus individual PNG files for each batch seed.

What you need first

  • Claude Code installed
  • Node.js, to run the two scripts with node
  • A p5.js, Canvas 2D, three.js or SVG sketch in a project folder
  • Playwright installed in your project (npm i -D playwright && npx playwright install chromium)

Steps

  1. /plugin marketplace add camilleroux/genart-skill
  2. /plugin install genart@camilleroux-genart
  3. npm i -D playwright && npx playwright install chromium (inferred, check the README)
  4. node "$CLAUDE_PLUGIN_ROOT/scripts/render.mjs" myproject --grid 50
  5. node "$CLAUDE_PLUGIN_ROOT/scripts/render.mjs" myproject --batch 50

Prompt for your agent

Using the genart plugin from camilleroux/genart-skill, run render.mjs on <sketch-folder> with --grid 50 and then with --batch 50. Expect one contact sheet image and fifty individual PNG files. Verify that the grid shows fifty distinct seeds before the batch files are used for review.

Caveat. The grid and batch outputs show what the sketch renders, so they cannot confirm print or pen plotter output, which the README does not describe in detail.
