SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Translating a vague project or feature idea into a concrete, structured PRD that Ralph can use to guide goal-driven iterations and prevent scope creep.

Core Features & Use Cases

  • PRD generation: Convert a project description into a comprehensive PRD that includes problem statement, goals, non-goals, acceptance criteria, technical constraints, and implementation phases.
  • Ralph integration: Produce a PRD that Ralph can reference as completion criteria to drive iterative improvement.
  • Use Case: Given a new feature idea, generate a PRD that defines scope, milestones, and success criteria for Ralph to execute.

Quick Start

Provide a project or feature description to generate a PRD at .omx/plans/prd-{slug}.md.

FAQPage Schema
How do I generate a PRD from a feature description to prevent scope creep?

A PRD guides iterative product development by defining problem statements, goals, non-goals, acceptance criteria, technical constraints, and implementation phases, providing clear completion criteria to prevent scope creep during goal-driven loops.

How do I structure acceptance criteria and implementation phases for a new feature?

Structure acceptance criteria and implementation phases by generating a PRD that explicitly separates goals from non-goals, lists technical constraints, and organizes milestones into phased implementation plans saved as markdown files.

What is the best way to translate a vague project idea into a structured product requirements document?

Translating a vague project idea into a structured product requirements document requires defining the problem statement, setting measurable goals, identifying non-goals, and mapping implementation phases to guide concrete iterations.

Can I use a generated PRD to define milestones and success criteria for iterative workflows?

Yes, a generated PRD defines milestones and success criteria for iterative workflows by establishing acceptance criteria and phased implementation plans that serve as reference points for goal-driven improvement loops.

Does ralph-init require any specific dependencies or environment setup to create a PRD?

Ralph-init requires no external dependencies or environment setup to create a PRD; you only need to provide a project or feature description to generate the structured document and save it to the .omx/plans directory.

When do I need a PRD with explicit non-goals and technical constraints for product development?

You need a PRD with explicit non-goals and technical constraints when managing complex product development workflows, ensuring that iterative cycles stay aligned with milestones and avoid expanding beyond the defined scope.
