The world's first open-source AI-native vector design tool and the first to feature concurrent Agent Teams. Design-as-Code. Turn prompts into UI directly on the live canvas. A modern alternative to Pencil.
OpenPencil is an open-source vector design tool where users describe interfaces in natural language and edit them on a live canvas with AI. Designers and developers use it for UI creation, design iteration, and coordinating multiple AI agents on different parts of a page. The catalogue entries provide instructions for working with OpenPencil.
These files are ZSeven-W/openpencil's own configuration. They tell Codex, OpenCode and Claude Code how to work on this repository, so they are not mods to install elsewhere. Copy one as a starting point and replace the parts that are about this project.
