Milestone Planning

Purpose

Turn a clear direction into roadmap structure. This skill owns docs governance, not task-local design.

Use when

• planning direction is clear enough to decompose
• milestone boundaries, module grouping, or task breakdown still need decisions
• the user needs roadmap-level tasks before task-local spec.md work can begin

Do not use when

• goals, constraints, or now-vs-later boundaries are still genuinely unclear
• the current task is already selected from confirmed roadmap state
• the work now is task-local spec, plan, implementation, or branch closing
