Generate without tools or checkpoint writes.
Use the thread's latest server-resolved model and instructions, falling
back to checkpoint settings or the workspace's bootstrap model. Restore
the checkpointed instructions, generation settings, and retry budget when
no live snapshot exists.
New and legacy threads restore memory and skills through the main
agent's loaders without writing updates back to the conversation.
Large older file arguments are truncated using the main agent's policy;
older context is dropped when needed to fit the side request's budget.
Instructions and questions that cannot fit raise ContextOverflowError.
Completed question/answer pairs from this side conversation.
Optional receiver for text fragments as the model produces them.
