SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Describe a feature in plain language and get a complete modular specification that identifies involved backend modules, defines interface contracts, outlines frontend components, and prescribes data changes.

Core Features & Use Cases

Module mapping: identifies backend modules touched by a feature.
Interface contracts: specifies cross-module data contracts and boundaries.
Frontend and backend specs: outputs UI component spec and backend module responsibilities.
Data changes & implementation plan: outlines necessary DB/state changes and a step-by-step guide for implementation.

Quick Start

Describe a feature in plain language and receive a complete modular specification for frontend, backend, and data changes.

FAQPage Schema

How do I generate frontend and backend specifications from a plain language feature description?▼

To generate modular specifications, describe a feature in plain language and the Skill produces complete frontend component specs, backend module responsibilities, and interface contracts. It maps involved modules and outputs a step-by-step implementation guide for engineers.

What are interface contracts and how do they enforce module boundaries in fullstack architecture?▼

Interface contracts define cross-module data boundaries and agreements. The Skill generates these contracts to enforce strict module boundaries across frontend and backend layers, ensuring decoupled modular architectures and preventing unauthorized cross-module data access.

How do I map backend modules affected by a new feature across a modular architecture?▼

Mapping backend modules involves analyzing a feature description to identify all touched backend modules. The Skill automates this by generating modular mappings that outline each module's responsibilities and necessary data changes for the feature.

Can I use this to plan database and state changes alongside frontend component specs?▼

Yes, you can plan database and state changes alongside frontend specs. The Skill outputs a comprehensive data-change plan that outlines necessary DB and state modifications, paired with UI component specifications and backend responsibilities.

What's the best way to create a step-by-step implementation plan for fullstack features?▼

The best way to create an implementation plan is to input a feature description. The Skill generates a step-by-step implementation path covering frontend components, backend modules, interface contracts, and data changes that can be directly handed to engineers.

Do I need an existing modular architecture to generate interface contracts and module mappings?▼

No existing architecture is required, but the Skill is designed for frontend-backend work across modular architectures. It identifies involved backend modules, defines interface contracts, and enforces module boundaries to guarantee a structured implementation path.
