Modes
The mode decides how far the agent goes on a single message before handing control back. It is independent of approvals (including Bypass). The mode belongs to the session: pick it from composer Quick settings, or from the session's row under Settings → Sessions. The mode a new session starts on is the Default on that page.
Three built-in modes ship on every plan. Each has a colour on the Quick settings chip and on Settings → Modes: Auto is quiet grey, Plan is yellow, Answer is blue.

Built-in modes
Runs tools step by step and stays in the loop between steps. Default for real work. Respects your approval rules unless Bypass is on. Quiet grey on the Quick settings chip.
Custom modes ProTeamEnterprise
The paid plans allow you to build modes of your own.
Under Settings → Modes, create a mode with a name, an icon, a colour (the same palette Auto, Plan, and Answer use on the Quick settings chip), a turn ceiling, optional time and token budgets, and Keep working without handing back.
- Switch on: the agent keeps going until the task is done, a limit hits, or you stop it. You can still type while it works: steer the current task, or queue the next one.
- Switch off: behaves like Auto, with the ceiling you set.
Modes you already built stay selectable if the plan changes.
Without a natural pause, a stuck loop burns tokens. Turn ceiling, time, and token budgets are on the same card.
A custom mode still uses Auto's tools and your approval policy. Looping alone does not skip approvals.
