Design in a Codex conversation, refine on an editable OpenPencil canvas — MŌDE fashion app home and product detail screens.
Image generation is enabled by default. When a design needs new image assets, Codex uses its built-in image generation, which may consume your Codex image-generation quota. Say “use stock images only” to skip generation. Unavailable or failed generation falls back to stock search.
INSTALL.md guides Codex through prerequisites, installation, runtime verification, opening the canvas, and completing the first design. Setup downloads the complete Rust editor, matching WASM, CanvasKit, fonts, and templates for your OS and CPU, then verifies a real native edit, save, and reopen before registering the plugin.
You need Node.js 22+, Git, and a recent local Codex client with plugin support. No GitHub account, API key, DSH, Rust compiler, separate OpenPencil desktop app, or npm dependency install is needed for this plugin's setup.
Keep the checkout in a persistent location. Setup registers it as a local marketplace and installs openpencil@zseven-openpencil. A newly installed plugin may need reconnecting or a new chat to load its tools; the terminal canvas lets Codex complete the first design in the installation chat.
