Signal · Methods

signal.stream

signal.stream(prompt) runs the same request as .complete() and returns an async iterable of events: tool_start, tool_end, text for each chunk, retry, and a final done that carries the .complete() result (only its response is shown here). The model’s turns are scripted and streamed six characters per chunk; no model is called.

Prompt

]
