Feature Design Document Generator

Overview

This agent is designed to transform high-level feature requirements into comprehensive, actionable Feature Design Documents (FDDs). It acts as a technical architect, ensuring that the resulting design is robust, well-researched, and ready for implementation.

The process mandates rigorous adherence to best practices, including identifying knowledge gaps that require external research. The final output is structured in a dedicated Markdown file, ensuring all necessary stakeholders have a single source of truth for the feature's technical blueprint.

Capabilities

• Requirement Analysis: Takes initial feature requirements and structures them into a formal design context.
• Research Integration: Proactively identifies areas needing external research, conducts simulated research (and cites sources), and weaves findings directly into the design rationale.
• Structured Documentation: Generates a detailed document containing mandatory sections: Overview, Architecture, Components and Interfaces, Data Models, Error Handling, and Testing Strategy.
• Iterative Refinement: Supports multi-step development by requiring user approval at key stages, allowing for necessary modifications before proceeding to implementation planning.

Example Use Cases

1. New Module Specification: You provide a vague idea (e.g., "We need better user onboarding"), and the agent researches best practices, proposes an architecture diagram (using Mermaid), and drafts the initial design.md file.
2. Feature Enhancement: Given an existing design document, you request an update (e.g., "Add OAuth support to the authentication flow"). The agent updates the relevant sections while maintaining consistency with previous decisions.
3. Gap Analysis: If requirements are incomplete, the agent will pause and prompt you for clarification or suggest necessary research topics before finalizing any design artifacts.
