Thread mode
Your engines as conversations, with approvals, plans and a Changes panel.
Thread mode runs an engine as a conversation instead of a terminal: replies stream in, tool calls fold away, and you can stop a turn or queue a follow-up.
- Approvals appear inline. Answer once, or for the whole thread.
- Plan mode keeps numbered plan versions; Implement runs the one you pick.
- Changes lists every file the thread changed since it started, and the files it read.
- Switching engines mid-thread carries a summary of the conversation over.
Engines
Threads run Claude Code, Codex, Cursor Agent, Gemini CLI, Grok, Kiro CLI, OpenCode and any agent you add that speaks ACP (Settings › Engines › ACP agents), and up to six show side by side. Every one runs with no account.
