From 7cab83385abb045b460bce3735458fa245500654 Mon Sep 17 00:00:00 2001 From: Jeffrey Phillips Freeman Date: Thu, 12 Mar 2026 00:52:34 +0000 Subject: [PATCH 1/3] feat(tui): implement Textual MainScreen with sidebar states and Dracula theme Implement the TUI MainScreen using Textual >= 1.0 (ADR-044) with: - CleverAgentsApp: root App subclass with Dracula theme - MainScreen: primary chat interface with 3 sidebar states (hidden/visible/fullscreen) cycled via shift+tab - Sidebar: right-docked collapsible panel for plans and projects - Conversation: scrollable message stream with block cursor navigation - SessionTabs: multi-session tab bar (auto-show with >=2 sessions) - Throbber: rainbow gradient (12 color stops, 15fps) and rotating quotes loading - PromptArea: input prompt with mode indicators and persona bar - FooterBar: context-sensitive hotkey reference - Dracula theme: canonical color palette with semantic token mapping - Safety behaviors: double-tap ctrl+c quit (5s window), escape cascading - Textual Web compatibility maintained (App subclass) Add textual>=1.0.0 as project dependency in pyproject.toml. Behave BDD tests for all widget states, theme constants, and behaviors. Robot Framework integration tests with helper scripts.
