Features

  • High-fidelity streaming with callbacks for every lifecycle event
  • Block start/end notifications for UI rendering
  • Real-time streaming of text, thinking, and tool arguments
  • Tool execution and result callbacks
  • Message history management
  • Dynamic instruction override
  • Toolset composition

Installation

pip install bond-agent

Quick Start

)
# Stream with console outputhandlers=create_print_handlers(show_thinking=True)
response=awaitagent.ask("Remember my preference for dark mode", handlers=handlers)

Streaming Handlers

Bond provides factory functions for common streaming scenarios:

  • create_websocket_handlers(send) - JSON events over WebSocket
  • create_sse_handlers(send) - Server-Sent Events format
  • create_print_handlers() - Console output for CLI/debugging
