SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Auto-generates PRDs and design docs from an existing codebase, enabling rapid onboarding and understanding without tribal knowledge.

Core Features & Use Cases

  • Generate PRDs from code structure and module relationships.
  • Produce technical Design Docs that describe architecture, data models, and dependencies.
  • Use Case: Onboarding a new team and handing off a codebase to a new maintainer with ready-to-review docs.

Quick Start

Provide the codebase path and say 'reverse engineer' to generate PRDs and design docs

FAQPage Schema
How do I generate PRDs and design docs from an existing codebase?

To generate PRDs and design docs from a codebase, parse the code structure and module relationships, map them to templates, and verify alignment. This automates extraction of architecture and data models for ready-to-review documentation.

What is the best way to create technical documentation for codebase handoffs?

Creating technical documentation for codebase handoffs involves reverse engineering the code to produce design docs describing architecture and dependencies. This enables rapid onboarding without relying on tribal knowledge from previous maintainers.

Can I automate onboarding documentation for multi-language projects?

Yes, you can automate onboarding documentation for multi-language projects by parsing the codebase structure and mapping it to PRD templates. This generates consistent architectural reviews and module relationship mappings across different languages.

How does code analysis map to PRD and design doc templates?

Code analysis maps to PRD and design doc templates by parsing the existing codebase, extracting structural relationships, and fitting them into predefined documentation formats. It verifies that the generated docs align directly with the actual code.

Do I need a specific framework to reverse engineer code structure into documentation?

No specific framework is needed to reverse engineer code structure into documentation. You simply provide the codebase path and initiate the process to auto-generate PRDs and design docs across multi-language projects.

What are the limitations of auto-generating design docs from code?

Auto-generating design docs from code is limited to parsing explicit code structure, module relationships, and data models. It cannot extract implicit business logic or contextual requirements not directly represented in the codebase architecture.
