What problem does it solve? Choosing how to migrate a legacy system is a high-stakes decision with unclear trade-offs. This Skill structures that decision by evaluating applicable migration strategies against your project brief, paradigm gap, and risk appetite, then producing a justified recommendation, a risk register, and a cutover plan while leaving the final choice to a human. ## Core Features & Use Cases - Strategy evaluation with explicit trade-offs: Filters strategies from a catalog (Strangler Fig, Big Bang, Parallel Run, Branch by Abstraction) and scores each against appetite, paradigm gap, cost, risk, and time. - Risk register generation: Produces risk_register.md covering technical, operational, organizational, regulatory, and data risks, each with probability, impact, mitigation, contingency, and owner. - Cutover planning: Generates cutover_plan.md with prerequisites, window, step-by-step owners and durations, rollback plan, and go/no-go criteria. - Use Case: After the Curator has documented target business rules for a legacy banking system, invoke this Skill to compare Strangler Fig versus Parallel Run, receive a justified recommendation, and get a complete risk register and cutover plan ready for human sign-off. ## Quick Start Run /reversa-strategist after the migration brief, paradigm decision, and target business rules exist to generate the strategy, risk register, and cutover plan in _reversa_sdd/migration/.
