SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Converts a Product Requirements Document into a comprehensive technical architecture specification, ensuring decisions about patterns, tech stacks, data models, and app structure are clearly captured.

Core Features & Use Cases

Automated architecture generation: derives architecture pattern, technology choices, and data models from PRD.
Documentation artifact: outputs ARCHITECTURE.md ready for design review and implementation.
Use Case: When starting a new iOS/macOS project, generate a complete architecture spec to guide engineers and stakeholders.

Quick Start

Provide the PRD at docs/PRD.md and prompt architecture-spec to generate ARCHITECTURE.md.

FAQPage Schema

How do I generate an architecture spec from a PRD for an iOS app?▼

Generating an architecture spec requires placing your PRD at docs/PRD.md and confirming an MVP scope to extract features and data models, outputting a complete ARCHITECTURE.md detailing patterns and tech stack for iOS projects.

What is needed to convert a product requirements document into architecture documentation?▼

You need the PRD located at docs/PRD.md and a confirmed MVP scope. These inputs allow the system to extract features and data models to drive determinate technology decisions for the architecture documentation.

Does architecture spec generation work for macOS app projects?▼

Yes, architecture spec generation applies to macOS app projects. It reads the PRD to derive the architecture pattern, technology choices, and data models, outputting an ARCHITECTURE.md detailing the tech stack and app structure.

What is included in the generated ARCHITECTURE.md file?▼

The ARCHITECTURE.md file includes the architecture pattern, tech stack, data models, and app structure. These elements are derived by extracting features and platform constraints from the input PRD.

Why do I need a confirmed MVP scope before generating an architecture specification?▼

You need a confirmed MVP scope to drive determinate technology decisions. Without a confirmed scope, the system cannot accurately extract features and platform constraints to generate the complete architecture specification.

Can I use this tool to derive data models and tech stack choices from product development plans?▼

Yes, the tool reads the PRD and product development plan to extract features and platform constraints, generating a complete architecture specification that includes derived data models and tech stack choices for your app.
