Milestone Planning

Plan roadmap structure before task-local spec work begins.

This skill decides Milestone -> optional Module -> Task shape. It owns roadmap-layer docs/tasks/ structure and governance, not task-local specs or implementation flow.

Composition

• Entry: reached from doc-driven-spec-workflow after scope is clear enough to plan delivery structure.
• Owns: milestone boundaries, optional module grouping, roadmap-layer task breakdown, backlog/handoff governance, planning-stage docs/tasks/ documents.
• Does not own: repository scaffold bootstrap, task-local spec.md, task-local plan.md, readiness checks, implementation, verification, branch closing.
• Handoff: use doc-driven:task-spec-execution only after the current concrete task is selected and the user wants to enter spec-first execution.
