Summary
- Generate a comprehensive Business Requirements Document (BRD) or Functional Specification Document (FSD) from project requirements, PRDs, briefs, or interactive interviews.
- Use this skill whenever the user mentions BRD, business requirements, functional specs, FSD, software specification, feature specification, system specification, functional requirements document, or wants to document business needs or how a system should behave.
- Also trigger when users ask to "spec out" a feature, write up requirements, or create a detailed plan for stakeholders or developers — even if they don't use the exact terms explicitly.
