What is the Canvas skill for Claude Code?

It is a toolkit that allows Claude to spawn interactive terminal user interfaces (TUIs) like calendars and document editors in a separate tmux pane.

Does this skill require tmux?

Yes, spawning interactive canvases requires an active tmux session to manage the split-pane display while keeping the main terminal active.

Can I use my mouse with the Canvas TUI?

Yes, the skill is designed for terminals with mouse support to allow for easy clicking, seat selection, and time-slot picking within the TUI.

How do the canvases communicate with Claude?

They use Unix domain sockets for Inter-Process Communication (IPC) to send user selections and status updates back to the Claude controller.

What types of canvases are currently supported?

The toolkit currently includes specialized canvases for calendar management, document editing, and flight booking comparison.

Productivity & Workflow

Provides interactive terminal-based UI components for Claude Code to display and control calendars, documents, and flight maps.

The Canvas skill acts as an external monitor for Claude Code, enabling the display and control of rich Terminal User Interfaces (TUIs) through tmux split panes. It allows developers to interact with complex data types—like scheduling meetings, editing markdown documents, and browsing flights—directly within their terminal workflow. By leveraging IPC communication and a high-level API, it transforms Claude from a text-based assistant into a visual, interactive tool for terminal-heavy productivity.
