Offload GSD's plan phase to Claude Code's ultraplan cloud infrastructure.
Ultraplan drafts the plan in a remote cloud session while your terminal stays free.
Review and comment on the plan in your browser, then import it back via /gsd-import --from.
⚠ BETA: ultraplan is in research preview. Use /gsd-plan-phase for stable local planning.
Requirements: Claude Code v2.1.91+, claude.ai account, GitHub repository.
