Worktree kit

Use the manager script for all worktree actions.

WORKTREE_SH="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/skills/flow-next-worktree-kit/scripts/worktree.sh"
[ -f "$WORKTREE_SH" ] || WORKTREE_SH="<plugin-root>/skills/flow-next-worktree-kit/scripts/worktree.sh"   # <plugin-root> = the directory two levels above this skill's SKILL.md file (the harness gave you that file's absolute path when the skill loaded); substitute it literally
bash "$WORKTREE_SH" <command> [args]

Commands:

• create <name> [base]
• list
• switch <name> (prints the worktree path; it cannot change your shell's directory - use cd "$(... switch <name>)")
• cleanup [<name>...] [--yes] (no args = interactive; names skip the prompt; --yes skips the confirmation, required off a terminal)
• copy-env <name>

Safety notes:

• create does not change the current branch
• create sets no upstream on the new branch (--no-track) - under the upstream-based push modes (simple, upstream, current) a bare git push cannot aim at the base branch; under the default push.default=simple (without push.autoSetupRemote) the first push needs git push -u origin <name> (legacy push.default=matching pushes all name-matched branches regardless of upstream)
• cleanup does not force-remove worktrees and does not delete branches
• cleanup deletes the worktree directory (including ignored files); removal fails if the worktree is not clean
• .env* is copied with no overwrite (symlinks skipped)
• refuses to operate if .worktrees/ or any worktree path component is a symlink
• copy-env only targets registered worktrees
• origin fetch is optional; local base refs are allowed
• fetch from origin only when base looks like a branch
• Worktrees live under .worktrees/
• create initializes .worktrees/.gitignore (* plus !.gitignore) when absent, so git add -A cannot stage nested worktrees as gitlinks; existing custom ignore files are preserved

Shared claim state. Parallel agents in sibling worktrees driving flowctl on the same repo share claim state via .git/flow-state. Set FLOW_STATE_DIR per agent (outside the tree) when running flow pipelines concurrently.
