Unable to continue the response

Error message

Unable to continue the response

What it means

The `.continue` REPL command resumes the previous response; it requires the last message to be 'continuous' (a response that hit a continuation boundary) and non-empty. If no such last message exists, it bails with 'Unable to continue the response'.

Solutions

1. Only use .continue immediately after a long response that was cut off mid-output
2. Send a message that produces a truncated response first, then .continue
3. Check with .last or session state that a continuous last message exists

Example fix

// before: unconditional .continue
.continue
// after: only continue when the previous reply was truncated
// (observe '...continuing' indicator or response length before issuing .continue)

// only .continue right after a truncated reply
let should_continue = session.last_message.as_ref()
    .map(|m| m.continuous && !m.output.is_empty())
    .unwrap_or(false);
if should_continue { repl(".continue")?; }

fn can_continue(last: Option<&LastMessage>) -> bool {
    last.map(|m| m.continuous && !m.output.is_empty()).unwrap_or(false)
}

match repl(".continue") {
    Err(e) if e.to_string() == "Unable to continue the response" => {
        eprintln!("No truncated response to continue; ask a new question");
    }
    other => other?,
}

When it happens

Trigger: Running `.continue` when the session has no last message, when the last message was not truncated/continuous, when its output is empty, or right after a completed short response.

Common situations: Typing .continue as the first command in a fresh session; using .continue after a response that finished normally; using it after .regenerate cleared the last continuous message; after switching sessions.
