Does Canvas require a specific terminal emulator?

Yes, Canvas requires either iTerm2 (on macOS) or an active tmux session to support the multi-pane splitting required for interactive canvases.

Can I interact with the canvases using my mouse?

Yes, the TUI components are designed with mouse support, allowing you to click to select calendar slots, seats, or document sections.

What happens if I don't have iTerm2 or tmux?

You can still run basic 'show' commands, but the 'spawn' command, which allows for side-by-side interaction, requires a supported multiplexer.

How does Claude communicate with the TUI components?

The skill utilizes an IPC (Inter-Process Communication) layer via Unix domain sockets to exchange state and event data between the terminal controller and the UI.

Is Canvas compatible with remote server environments?

Yes, as long as you run Claude Code within a tmux session, the canvas spawning functionality will work over SSH or on remote machines.

Productivity & Workflow

Enables interactive, multi-pane terminal user interfaces for Claude to manage calendars, documents, and complex data visualizations.

Canvas provides a specialized framework for Claude to spawn and control rich Terminal User Interface (TUI) components such as interactive calendars, markdown editors, and flight booking maps. By leveraging tmux or iTerm2 splits, it allows Claude to present graphical terminal elements in a separate pane while maintaining the primary conversation context. It features a robust IPC communication system for real-time data updates and supports terminal-based mouse interactions, providing a more intuitive way to handle complex tasks like scheduling or document review directly within the CLI.
