# Requirements & Functional Specification Document Generator

An agent skill that generates structured Business Requirements Documents (BRDs) and implementation-ready Functional Specification Documents (FSDs). It defines business goals, functional requirements, user interactions, acceptance criteria, and error handling — focusing on **what** the system must do and **why**, not how to build it.

Every generated FSD follows a structured 8-section template with MoSCoW prioritization, GIVEN/WHEN/THEN acceptance criteria, hierarchical requirement IDs (FR-X.Y.Z), and Mermaid diagrams for all visual representations. BRDs follow a 7-section template focusing on business goals, stakeholders, scope, and high-level business rules.
