How does Claude receive my selections from the TUI?

The terminal canvas communicates back to the controller via Unix domain sockets, sending 'selected' or 'cancelled' events containing the relevant data.

Does this skill support custom data for the calendar?

Yes, canvases are populated via JSON configurations passed through the --config parameter, allowing Claude to inject dynamic data from various sources.

How does the 'spawn' command differ from 'show'?

The 'show' command runs the canvas in your current terminal window, while 'spawn' opens the canvas in a new tmux split, allowing you to keep talking to Claude while using the UI.

What are the system requirements for the Canvas skill?

Canvas requires tmux for pane management, a terminal with mouse support for interactions, and the Bun runtime to execute the underlying TypeScript code.

Developer Tools

Provides interactive terminal user interfaces (TUIs) for managing calendars, editing documents, and visualizing data within tmux split-panes.

The Canvas skill empowers Claude to go beyond text-based interactions by spawning and controlling rich, interactive terminal components. Built for power users who live in the CLI, it enables complex workflows such as visual meeting scheduling, interactive markdown document editing, and seat selection for flights. By leveraging tmux and Unix domain sockets for IPC communication, it creates a seamless bridge between the AI's logic and a graphical-like terminal interface, allowing for precise user selections and live data updates without losing the context of the conversation.
