| description | After /start-task: park the current clean, pushed feature branch in its own issue-numbered nested worktree (.worktrees/<issue#>) and return the primary checkout to current main, so the next parallel lane can start. Writes the lane's port base and runs npm ci in the worktree. Use when the user says to move the branch or task to a worktree or open a parallel lane. |
Move-to-Worktree
Companion to /start-task for parallel Phase 4 lanes (see
specs/claude-lens-phase4-parallelization.md). /start-task leaves the primary
checkout on the new feature branch; this skill moves that branch into its own
worktree and puts the primary back on main — one worktree + one branch + one
Claude session per in-flight issue.
Run (1 bash call)
bash {base_directory}/move-to-worktree.sh
No arguments — it operates on the branch currently checked out. The script:
- Hard-stops unless run in the primary checkout, on a task branch
(
{type}/{issue#}/{slug}), with a clean tree and its matching origin/ upstream set —
i.e. exactly the state /start-task leaves behind.
- Pushes any local-only commits, checks out and fast-forwards
main (this must
happen before the worktree is created — git refuses to check out a branch
in two places).
git worktree add .worktrees/<issue#> <branch> — nested inside the repo root
(gitignored), never a ../ sibling. The context file specs/context/<issue#>.md
travels with the branch (it's committed).- Writes the lane's port block to
<worktree>/.env.local (gitignored):
CLAUDE_LENS_PORT_BASE = 4128 + 10 × issue# — backend = base, Vite = base+1,
E2E = base+2, Storybook = base+3. Issue-derived, so lanes cannot collide.
- Runs
npm ci in the worktree (per-worktree node_modules; also wires
the Husky pre-push hook so npm run verify gates pushes from this lane).
Non-zero exit → hard-stop, print stderr verbatim.
Report
The script's summary block (worktree path, branch, ports), plus: "Open a new
Claude session in the worktree and continue the pipeline there
(/plan-architecture / /implement → /review → /commit → PR with
Closes #N)."
When the PR has squash-merged, /finish-worktree <issue#> (run back in the
primary) does the teardown.
You Must NOT
- Run the underlying git commands yourself — the script owns all mutation.
- Stash, discard, or commit anything to satisfy the clean-tree check — hard-stop instead.
- Move a branch whose upstream is ahead or does not match
origin/<branch>.
- Create the worktree while the primary is still on the feature branch.
