This gives Claude the context to help you build terminal UIs with Textual's Python framework. It covers the full architecture from reactive state management and event handling to screens, custom widgets, and TCSS styling. The reference sheets for built-in widgets and CSS properties are especially handy when you're mid-build and can't remember if a DataTable emits RowSelected or CellSelected. Use this when you're scaffolding a new TUI app, debugging layout issues, or trying to figure out why your reactive variable isn't triggering a watch method. It's dense but organized well enough that Claude can pull what's relevant without drowning in the full Textual docs.
