Worktrees and Dev Servers

Pierre includes a repo-specific git worktree helper for local/manual parallelization outside host-managed agent workspaces. Managed Pierre worktrees live at:

~/pierre/pierre-worktrees/<slug>/

Each managed Pierre worktree owns a port offset so dev servers, E2E fixtures, and the Chrome remote-debug instance do not collide. The main clone keeps historical default ports; linked Pierre worktrees shift ports.

If you are already inside a Conductor, Codex, Claude, or other host-provided workspace, do not create another worktree unless the user explicitly asks for a Pierre-managed worktree. Still use this skill when you start repo dev servers or E2E fixtures, because the cleanup and port-offset rules apply to those scripts.
