Live Task Status Panel

Visual Reference

Based on Claude Code TUI design patterns.

Requirements

Task List Display

• Toggle visibility with ctrl+t
• Header format: Tasks (X done, Y open) · ctrl+t to hide tasks
• Task items with status icons:
  • ✓ (green) - Completed tasks
  • □ (dim) - Pending/open tasks
• Task format: [icon] #N Task description

Live Agent Activity Section

• Appears below task list when agents are running
• Idle indicator: ✱ Idle for Xs (shift+↑/↓ to select)
• Tree-style agent lines:

  ├─ agent-name: ◇ Activity… · X tool uses · Y tokens
  └─ agent-name: ◇ Activity… · X tool uses · Y tokens
  

Layout

• Panel appears at bottom of screen, above input
• Should not obscure conversation history
• Collapsible via keyboard shortcut

Acceptance Criteria

• ctrl+t toggles task panel visibility
• Task counts update in real-time
• Completed tasks show green checkmark
• Pending tasks show empty box
• Agent activity lines show when tasks are running

Note: Fixed panel approach abandoned per #76 research. Live task status will need to be inline (print status lines between output chunks) rather than a dedicated panel. Depends on #73, #74.

Consolidated into new issue. Partially addressed by #95 (elapsed time, nested child tool). Remaining work: ctrl+t toggle panel, task counts header.
