## Description

Use Git worktrees to isolate parallel coding tasks. Use when setting up a task checkout, working in a shared repo, or managing existing worktrees.

# Git Worktrees for Parallel Agents

## In Cloudroom (`$ROOM_THREAD_ID` is set)

Never run `git worktree add` yourself. Cloudroom only deletes worktrees it made, so hand-made ones pile up in `~/code` forever.

- **New task:** start the thread with **New worktree** instead.
- **Move this thread to its own worktree:** fork it into a Cloudroom-managed worktree. Cloudroom makes the branch and deletes the folder once its last thread is archived (after the worktree retention setting, default 21 days).

  ```bash
  room-cli thread fork "$ROOM_THREAD_ID" --new-environment worktree --title "<task>" \
    --prompt "You now run in a new worktree. Copy the gitignored .env files from <primary checkout> into it, then stop and wait for the user."
  ```

  It branches from `main`, so uncommitted edits stay behind; commit them first or pass `--base-branch <ref>`. Then tell the user to continue in the new thread and archive this one. Skip the rest of this skill.

## Start here

Detect where you are before editing:

```bash
[ "$(git rev-parse --path-format=absolute --git-dir)" = "$(git rev-parse --path-format=absolute --git-common-dir)" ] \
  && echo "primary checkout" || echo "worktree"
```

- **Primary checkout** → create a task-named worktree, complete the setup below, and `cd` into it before editing.
- **Worktree** (including one created by Cursor) → proceed with the task.

## Working model

Worktrees have separate working files and branches but share Git history, stashes, config, and refs.

- **One task = one worktree = one agent session.** Never share a working directory between agents.
- Keep the primary checkout on main, only for review, merging, and pushing.
- Nothing auto-merges. The human reviews each diff before merging or discarding the worktree.
- Keep task branches local and short-lived. Push only main unless the user explicitly asks to push a task branch.
- Merge one worktree at a time. If main moved, rebase the task branch before merging.
