What problem does it solve? Coordinating a multi-phase milestone across planning, implementation, and validation workflows requires constant manual scheduling decisions. This Skill acts as a thin controller that reads milestone status and dispatches the correct owning workflow for each safe actionable item, parking blocked work and continuing elsewhere instead of stalling. ## Core Features & Use Cases - Status-driven scheduling: Reads specbind milestone status --json as the single source of truth and dispatches exactly one owning Skill or guarded CLI action at a time, never reconstructing schedules from Roadmap prose. - Cause normalization and parking: Classifies every returned condition as RETRYABLE, REPAIRABLE, REROUTABLE, WAITING, BLOCKED, HUMAN_DECISION, EXTERNAL_BLOCK, or COMPLETE, then continues independent work on other branches. - Authorized replan routing: With --replan or explicit maintainer delegation, loads references/replan.md to route Design, Contract, and Tasks recovery through the owning planning Skill without expanding scope. - Use Case: A maintainer asks to advance the active milestone; the Skill dispatches implementation items to sb-implement, parks a blocked design decision as HUMAN_DECISION, continues unrelated reachable work, and stops before any release execution. ## Quick Start Use sb-drive to advance the active milestone through every safe reachable action and report what remains blocked.
