 Sessions resume the **most recently updated** session for the current workspace unless you pass `--new` or `--session`. Each session remembers the last **provider** and **model** (restored on resume so you are not re-prompted).
 
+When a tool-loop or PTY limit is hit, the prompt accepts `y` (continue once), `n` (stop), or `yyy` — **stop asking for the rest of this turn** (the next user turn prompts again). `--auto-continue` / `[agent] auto_continue_limits = true` skip the prompt for every turn.
