Included Skills2

indexskills/index/SKILL.md

Route large, multi-step, deadline-bound, or project-sized work into Planner. Activate when an outcome needs dependent deliverables, more than one work session, or explicit execution governance.

plan-projectskills/plan-project/SKILL.md

Create, audit, or refine a practical project plan. Always run an explicit five-question owner clarification round before planning, then lock scope and quality and produce sub-20-minute current-slice tasks with deadlines, resources, reusable artifacts, rubrics, and Definitions of Done.
