Agent Skills: ring:using-pm-team

Routing feature planning through the ring-pm-team pre-dev workflow: choosing the Small Track (4 gates, <2 days) or Large Track (8 gates, 2+ days) and entering via ring:planning-small-features or ring:planning-large-features. Indexes pre-dev gates, standalone utilities, and research agents. Use when starting a feature that needs systematic planning. Skip for quick exploratory work, known-solution bug fixes, or trivial changes.
