Key point

XLI, an open-source Python library for improving the terminal UX of AI agents, has been released.

Details

The open-source Python library XLI, which helps implement the tricky terminal UX needed when developing AI agents, has been released.

Existing TUI frameworks like Textual or Ratatui have the problem of occupying the entire screen, which interferes with the terminal's scrollback functionality. XLI, on the other hand, uses an inline rendering approach, allowing users to experience a rich UI while still retaining the existing terminal's scroll, selection, and search functions.

Key features:

  • Streaming markdown responses and slash (/) command support
  • Real-time updating Tool cards and inline approval/selection tools
  • File mention (@) functionality and ESC-based interrupt support
  • Framework-agnostic design compatible with a variety of agents

It can be used right away via pip install python-xli.
