What problem does it solve? Ambiguous or high-stakes tasks often get executed with incomplete requirements, leading to wrong work. This Skill enforces a rigorous planning phase before execution: it interviews you to clarify requirements, challenges assumptions adversarially, and synthesizes a verified, handoff-ready plan. ## Core Features & Use Cases - Three-Role Planning Loop: Metis clarifies requirements and acceptance criteria, Momus challenges assumptions and missing verification, and Oracle synthesizes the final plan with a machine-checkable verification matrix. - Deterministic Checklist Clearance: The interview exits only when a 6-item checklist (objective, scope, acceptance, test strategy, handoff target, no critical gaps) is fully resolved, capped at 5 rounds with carried-forward blockers. - OMX Handoff Contract: Produces a durable plan artifact under .omx/plans/prometheus-strict/ and recommends handoff to $ultragoal or $team only when parallel lanes are justified. - Use Case: Before starting a risky multi-service refactor, run this Skill to pin down scope, non-goals, rollback conditions, and a verification matrix, then hand the approved plan to an execution workflow. ## Quick Start Ask the agent to run prometheus-strict on your goal, for example: plan the migration of the billing service to event-driven architecture before any code changes.
