capture-playbook

Create or revise the exact project Playbook the user requests, including when they invoke /capture-playbook. Use the request as the design brief, ask only questions that materially change the Playbook, and write the agreed Playbook in the selected Trellis root. Do not mine conversations or discover candidates; route reflective requests to /discover-playbooks. Supporting mechanics may use a private safe _cli tool or an explicitly requested project-owned script.
