Recreate a worktree on a second machine that has only a clone: fetch origin, attach the existing remote branch (no -b new branch, no handoff required), and launch plain Claude Code so the user can run a resume-side command (/cdd-process-pr, /cdd-merge-base, /cdd-pre-pr). With no argument, list remote feature branches not already checked out and prompt for one. Scope is worktree + branch recreation only: the handoff (<branch>.md) and state record (<branch>.state.json) stay local per machine and are not synced. That is safe because the resume-side commands read PR/branch state from git and gh, not the handoff, and cdd-state set no-ops when absent. Cross-machine sync of those artifacts is recorded as remaining Phase-13 work (the refs/cdd/<branch> design sketch in the roadmap). - tools/cdd-worktree.sh: new cdd-worktree-resume + "Provides" header entry - scripts/worktree-resume-assert.sh: local-bare-repo-as-origin smoke with a stubbed claude; wired into template-smoke.yml - process doc §2.8 (four commands + multi-machine note) and §2.13 refinement - roadmap Phase 13: split #22 into landed worktree-resume + deferred sync - README + both CLAUDE.md workflow sections; CLAUDE.md build/test list Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Discovery built candidates from `%(refname:short)` and stripped an `origin/` prefix to drop the origin/HEAD symref. That short form is "origin/HEAD" on git 2.34 (strips to "HEAD", excluded) but just "origin" on newer git (CI), which slipped past the HEAD check and became a bogus first candidate — `git worktree add --track -b origin origin/origin` then failed, so discovery mode exited 1 in CI. Iterate full refnames (`%(refname)`) and strip the full `refs/remotes/origin/` prefix instead; refs/remotes/origin/HEAD is stable across git versions, so the symref is excluded everywhere.

Summary
Adds
cdd-worktree-resume [<branch>], a fourth command on the shared worktree helper, for picking up a task started on another machine. It recreates a worktree tracking an existing remote branch (no handoff required) and launches plain Claude Code so the resume-side commands (/cdd-process-pr,/cdd-merge-base,/cdd-pre-pr) can run. With no argument it lists remote feature branches not already checked out and prompts for one.Scope is deliberately worktree + branch recreation only — the handoff and per-task state record are local-per-machine and are not synced. That's sound because the resume-side commands read PR/branch state from git and
gh, andcdd-state setno-ops when the record is absent. Cross-machine sync of the handoff and state record is tracked as separate follow-up work.Changes
tools/cdd-worktree.sh— newcdd-worktree-resumefunction + header docs. Additive: no change to the layout or any existing command, so a newer helper stays backward-compatible with every project version.scripts/worktree-resume-assert.sh(new) — local-bare-repo-as-originsmoke covering explicit resume (tracking worktree + claude launch), already-exists (return 0, no relaunch), and discovery mode (numbered selection)..github/workflows/template-smoke.yml— runs the new smoke; existingbash -n/shellcheck globs already cover the new script.Verification
All
/cdd-pre-prgates pass: command-set drift clean, prompt seams clean, install smoke, worktree-resume smoke, end-to-end bootstrap smoke, demo seed-overlay smoke,bash -nclean. No upstream drift.Closes #22
