Launch parallel workspaces on their own branches, resume them across restarts, and retire them with Archive when the work ships.
Each workspace has its own git worktree, so parallel agents never write to the same checkout. Run as many as your machine holds.
Launch a workspace from its repository's group in the sidebar. Two launch modes decide the branch:
Forks a fresh branch for the task. This is the default for new work.
The first prompt you send is the workspace's starting line, the one place the task is written down. Keep it to one task, so the changeset you read later reads as one thing too.
Every workspace has a base branch: the repository branch its changes merge into, and what its git status and changeset are measured against.
It starts as the repository's default branch. You can point it somewhere else later in Checks, where the merge happens.
Launch more workspaces for more tasks. Each one has its own agent and runs on its own, and the sidebar shows you which one needs you.
When two workspaces in flight touch the same file, Cohalen marks the collision, so you see the merge conflict coming before it lands.
The conversation is a session the coding agent itself writes to disk. Re-open a workspace, even after an app restart, and the agent picks up its context instead of starting over.
A workspace has two exits.
Archive you can undo. Delete you can't.
Archive retires a finished workspace from the active list. Cohalen commits whatever you left behind so nothing is lost. Then it runs the repository's archive script, takes the worktree off disk, and keeps the branch and the record under History.
Restore rebuilds the worktree from that branch, and the session picks up where it stopped. Archiving can also happen on its own when the pull request merges, which you set per repository.
Delete removes the worktree and the branch Cohalen created, then drops the record. A branch you brought yourself is never deleted. Delete asks first, and asks again when git turns it down for a dirty worktree or an unmerged branch.
