Environment Variables

• VIBE_READER_ROOT: Sets the root directory for file browsing (default: current working directory)
  • Files outside this directory cannot be accessed
  • Use this to restrict file browsing to a specific project

API Endpoints

Tmux:

• GET /api/tmux/tree - List all sessions/windows/panes
• GET /api/tmux/pane/{session}/{window}/{pane}?scrollback=1000 - Get pane content with configurable scrollback

Files:

• GET /api/files?path=. - List directory contents (relative to project root)
• GET /api/files/content?path=file.txt - Render file content (max 10MB) with fields path, render_mode, html, and metadata

Design Principles

1. Eink-first: No animations, high contrast, instant updates
2. Minimal overhead: Direct tmux capture, simple file operations
3. Space-efficient: Every pixel counts on small eink screens
4. Single-page: All content fits viewport, reduces refresh artifacts
