Threadlines v0.5.0

Highlights

Rooms are now on by default. Add a second agent to any thread, ask it something while the first one keeps working, and let agents ask each other for help or a review. The chat is easier to follow, and Cursor and fx join Codex and Claude Code.

• Add another agent to a thread. Pick a second agent in the model picker, even before the first message. Each agent keeps its own memory and gets a short catch-up on what it missed. Start a message with @ and a name to choose who it's for. Adding an agent turns off revert for that thread.
• Ask a question while another agent works. Message a Codex or Claude agent while another one is busy, and it answers on the side without touching files, so the work keeps going. Other agents wait their turn.
• Agents ask each other for help. An agent in a room can ask another a question, get an independent review of its changes, or hand off the next step. It can also ask you to bring in another model for a review. By default it asks you first, and Settings can turn this off.
• A chat that's easier to follow. Each agent's work hangs on one line under its name. Finished stretches of work fold into short plain-language lines you can open, and Claude shows what it's thinking instead of "Waiting for model".
• Cursor and fx as providers. Sign in to Cursor Agent or fx in Settings and use either one as a thread's agent, with its own models in the picker. They can join a room too.

Also improved

• Claude Sonnet 5.5 is in the model picker, and Ultracode is its own switch. The picker warns before a model retires and says what each speed costs.
• A thread shows the pull requests its agent opens, and the CI button turns yellow while checks run. Auto-fix also picks up checks that failed before you turned it on.
• Choose Send when done to hold a message until the reply finishes. A steer that arrives too late now waits as the next message instead of disappearing.
• Plugins & Skills loads much faster, and the usage page leads with tokens and splits each day by model.
• Revert on newer Codex threads edits the conversation in place, and going back to a thread's first message works again on Codex 0.159.
• Chats no longer jump or bounce while a reply streams, on a phone or with two agents writing.
