What problem does it solve? Tickets and design briefs often contain acceptance criteria with silent cases, contradictions, or ambiguous scope that surface as costly rework during implementation. This Skill audits each acceptance criterion against current system behavior and resolves every business unknown with the user before planning starts. ## Core Features & Use Cases - AC Walkthrough: Parses acceptance criteria into typed items (new behavior, modification, or integration) and walks each one against the existing codebase as business evidence. - Gap Detection: Surfaces silent cases, contradictions, hidden consumers, and ambiguous scope as concrete business questions, then records user resolutions. - Clarification Brief Output: Produces a business-only Clarification Brief (no file paths or implementation details) that the plan phase consumes directly. - Use Case: Given a Jira ticket stating "VCC bookings should auto-confirm", the Skill reads current booking rules, discovers there is no VCC branch, asks what should happen for edge cases, and saves a resolved brief for the planner. ## Quick Start Ask the agent to clarify the acceptance criteria in your ticket or design brief before running the plan phase.
