The conversation panel is where everything starts. Tell the agent what to build, change, or ask about — it keeps context across turns, and it asks for clarification when it genuinely needs a decision from you rather than guessing. A few useful habits:
  • Plain English works. “Make the header sticky and move the login button right” is a complete instruction.
  • Technical vocabulary works too. Say “use Postgres” or “make it SSR” and the agent applies your choice rather than debating it.
  • Attach images in chat — a sketch, a screenshot of a bug, a design you like. They’re delivered to the agent with your message.
  • Small questions get direct answers. Asking “why is the total wrong?” doesn’t trigger a rebuild — the agent answers, and only builds when you ask for a change.

​
When the agent asks you something

Some decisions belong to you — and for those, the agent posts a question card in the conversation instead of guessing. If the question is blocking the build, the build holds until you answer; the workspace’s attention bar surfaces it on every tab so you can’t miss it. Questions are durable: they’re written down before they’re shown, and your answer is recorded before the UI claims success — so a refresh or a dropped connection never loses either side. When you answer a blocking question, the card tells you honestly whether the build resumed or is waiting idle.

​
Stopping

Press Stop in the top bar (or Esc) to halt a running turn. The button shows “Stopping…” until every part of the agent’s work has actually quieted — not just the visible message. Your project is left in a consistent state and you can pick up with a new instruction.

​
Tuning the agent

  • Model — change the project’s model any time from the top bar; the choice persists.
  • Thinking dial — Fast / Auto / Thorough controls how hard the agent reasons per turn. Auto (the default) is quality-first; Fast is cheapest and quickest for simple or throwaway iterations; Thorough applies maximum reasoning to every turn. Changes apply from the next turn. For a single hard problem, include the word ultrathink in your message to escalate just that turn.

​
Developer-tier extras

On the Developer tier, two more surfaces open up:
  • Memory Lens — see what the agent remembers about your preferences and project facts across turns; peek, pin, edit, or delete what it’s carrying.
  • Skill Shelf — browse the skills the agent can bring to bear.
Switch tiers any time from the top bar — see The workspace.
