I/O Interface Plugins

I/O plugins handle user interaction — displaying agent output and collecting user input. You need exactly one active I/O plugin.

I/O Event Flow

Both I/O plugins follow the same event pattern:

• Input: Collect user text → emit io.input
• Output: Receive io.output → display to user
• Streaming: Receive io.output.stream chunks → render incrementally
• Approvals: Receive io.approval.request → show dialog → emit io.approval.response
• Questions: Receive io.ask → show prompt → emit io.ask.response
• Status: Receive io.status → update status indicator
