What problem does it solve? Coordinating multi-phase specification planning across Requirements, Design, Contract Review, and Tasks is error-prone when scope, gate authority, and validation order are inferred rather than explicit. This Skill enforces a fail-closed orchestration route so every planning run has an explicit scope, authorized gates, and independent design validation before approval. ## Core Features & Use Cases - Complete planning route: Orchestrates one named Spec or all Specs through Requirements, Design, independent validation, global Contract Review, and Tasks approval via the specbind CLI. - Single-phase mode: Runs exactly one explicitly requested Requirements, Design, or Tasks phase for one named Spec without silently expanding scope. - Recovery and shared contracts: Handles Drive replan recovery with explicit rewind authority and prepares project shared Contracts for --shared scope. - Use Case: A maintainer asks to plan the active milestone; the Skill reads milestone status, asks for named or all-Spec scope, obtains gate delegation, dispatches phase receivers, and stops after Tasks approval with a full report. ## Quick Start Ask the assistant to use sb-plan to plan the active Spec work for a named Spec through its approval gates.
