Agent Skills: auto-prep

Prepare a team's certified backlog for a fleet of parallel /loop /auto sessions — audit `specified` labels for unattended-shippability (route human-gated issues by shape — `needs decision` for pending decisions, `human` for human-performed work — mark fleet-hostile ones `solo`, flag decision-gated ones), consolidate same-defect-family point fixes into class-scoped sweep issues, wire `blocks` edges between file-colliding candidates, validate through next-candidates.sh, audit the release scope (every unstarted Planned/Todo issue classified workable/needs-keeper-action/draining, blocker chains walked to their root causes, fan-out first — the keeper's personal unblock list leads the report) plus the second-order certified-Backlog fleet-drain edges, and recommend a parallel-session count. Use when the user says 'auto-prep', 'fleet prep', 'prep the backlog for auto', or before launching multiple /loop /auto sessions.
