Welcome screen
When no task is open you’ll see:- What’s new — a short carousel of recent features. It advances on its own and pauses while you hover; use the arrows to step through. Some items have a button that opens the feature directly (for example, Try it out now for Design Studio).
- Recent — your latest tasks with when they ran, token usage and size. Click one to reopen it, or click View all for the full history. Starred tasks show a star.

- Task title — click it to open the task details.
- Context ring — how much of the model’s context window the task is using. It turns amber as it gets close to full.

The transcript
Tool steps
Each action Sixth takes is one compact line, such as Readauth.ts, Edited auth.ts +7 −2, Ran npm test, Searched login or Listed src/. A spinner shows while a step is running.
Click a line to expand it:
- Edits and new files show the diff, with Open and Copy buttons.
- Commands show their output (shown automatically while a command is still running).
- Searches and listings show the results.
- Images and SVGs show a preview.
Approval cards
When Sixth needs permission, for example to run a command, edit a file or call an MCP tool, it shows a card with exactly what it wants to do (the command, the diff, the URL) and two buttons. Press Enter to approve or Esc to reject, or click the buttons. To say something different instead, just type a reply in the message box. Actions you’ve auto-approved skip the card.Thinking
When a model reasons before answering, a Thinking line shows its latest thought live. Afterwards it collapses to Thought for Ns; click it to read the full reasoning.Questions
If Sixth needs a decision, it asks with a numbered list of options. Press the number key or click an option, or type your own answer.Sub-agents and background work
When Sixth splits work across sub-agents, a Sub-agents group shows each one’s live activity, time and a Stop button. Background agents and long-running shells are listed under Agents & shells just above the message box.Checkpoints
A thin Checkpoint line appears after each change, with Compare and Restore buttons. See Checkpoints.Completion
When Sixth finishes, it shows Task completed with a summary and thumbs up/down for feedback. If files changed, click Review changes to see everything in a diff view.Your messages
