PRD to Design Requirements Document

Solving the Structural Gap in PRD-to-Design Handoff

In the product development lifecycle, Product Requirements Documents (PRDs) often focus on narrative descriptions of business logic and features, yet typically lack the structured, executable information designers directly need. This makes the conversion from a PRD to a design specification a time-consuming and error-prone manual task. Designers must repeatedly dissect, reorganize, and manually compile scattered descriptions into a complete design document that includes information architecture, interaction flows, page layouts, and visual guidelines, risking the omission of critical interaction details or exception-handling logic.

Core Capabilities and Workflow of the Skill

This skill automates this conversion process. Its core function is to accept unstructured PRD inputs and output a rigorously structured, content-specific design requirements document.

• Flexible Input: It can accept PRD files in PDF, Word, or Markdown formats, or Feishu document links, eliminating the need for manual format conversion.
• Structured Output: The generated design document adheres to a standardized set of sections, ensuring coverage of design considerations from macro to micro levels:
• Context & Scenarios: Distills project background, design objectives, and user personas/usage scenarios.
• Architecture & Flows: Automatically constructs a holistic information architecture diagram (generated in Mermaid syntax) and creates interaction flow diagrams covering main flows, branch flows, and exception flows.
• Specifications & Details: Defines specific page layouts and visual styles (colors, fonts, icons), while detailing interaction rules and motion specifications for each module.
• Risk & Deliverables: Identifies design risks and lists a clear design deliverables checklist along with analytics (tracking) requirements.

The skill's execution flow is straightforward: first, it uses the file tool to read and parse the PRD content; then, it generates specific, executable content section by section according to the structure above; finally, it renders the interaction flow diagrams into PNG images, and saves all artifacts (the Markdown document and images) in an artifacts directory.

Scope of Application and Important Caveats

This skill is well-suited for teams that have established clear PRD writing standards and wish to systematize and automate the initial design requirements structuring phase. It effectively helps designers build a solid initial design blueprint, saving significant time on early-stage information consolidation.

Important notes when using it:
- Source Document Quality is Key: The depth of the generated design document is highly dependent on the completeness of the input PRD. If the source PRD is overly sparse, the output may also lack specificity.
- Human Review is Indispensable: The output design document should be treated as an initial draft or framework. It must be reviewed, supplemented, and adjusted collaboratively by designers and product managers to ensure it fully aligns with actual design decisions.
- Specificity of Guidelines: The skill follows the principle of being "concrete and executable," attempting to extract and generate specific values (e.g., color codes, dimensions). However, for highly subjective design elements like brand tone or creative expression, manual definition and refinement remain necessary.
