Ralph

A self-referential persistence loop that won't quit until every user story in your PRD passes verification. It auto-generates a prd.json from your task, breaks work into discrete stories with testable acceptance criteria, then iterates until each one is verified complete by a reviewer (architect, critic, or codex). Sessions persist across retries, long operations run in background, and you get structured progress tracking. The mandatory reviewer step prevents the usual "looks good enough" problem where implementations get marked done with half the edge cases skipped. Skip this if you want manual control or just need a quick fix. Reach for it when "finish this completely" actually means completely.

Your previous attempt did not output the completion promise. Continue working on the task.

Ralph is a PRD-driven persistence loop that keeps working on a task until ALL user stories in prd.json have passes: true and are reviewer-verified. It combines session persistence, automatic retry on failure, structured story tracking, and mandatory verification before completion. NON-NEGOTIABLE, runs before any story work and at every verification gate:
