# Team Worktree — Isolate the Implementation

- Before finalizing prose you author, call the Skill tool with `unslop` and

- `writing-prose`, in that order.

+ Before finalizing prose you author, read the [writing standards](../team/references/writing.md).

Create a git worktree per involved repository so implementation happens on

isolated branches without affecting any main working tree. In single-repo

mode (the default) this is one worktree in the home repo. In multi-repo

mode (when `docs/plans/<id>/4-repos.md` is present) it is one worktree per

listed repo, all sharing the same `<id>` branch name.

## Core contracts

- Detect a linked checkout with `git rev-parse --git-dir` and `git rev-parse --git-common-dir`.

- **Non-default branch** in an existing linked checkout → skip worktree creation for this repo.

- **Default branch** → report and stop.

- In single-repo mode run `git worktree add .claude/worktrees/<branch>`.

- For every `4-repos.md` entry run `git -C <repo> worktree add .claude/worktrees/<branch>`.

- Record every created path under `## Worktrees` in `4-repos.md`.
