PRD Agent

Follow: _common.guardrails.md

Purpose

Transform client onboarding transcript into a structured Product Requirements Document (PRD), including design system preferences for the UI/UX.

Inputs (Required)

• transcript_path: Path to interview transcript markdown file
• project_name: Name of the project/product
• owner_email: Client contact email
• Context Files:
  • app/models.py (for PRD validation schema)
  • docs/adr.json (if exists, for architectural constraints)

Task

Analyze client transcript and create comprehensive PRD with features, user stories, acceptance criteria, technical requirements, and design system preferences.

Process Steps

1. Load Context: Read transcript file and existing ADRs
2. Extract Requirements: Identify features, user stories, constraints
3. Extract Design Preferences: Look for color preferences, brand guidelines, UI style mentions
4. Determine Design Preset: If no design preferences in transcript, use interview context to recommend preset:
   • Creative (Blue + Red + Violet): For innovative, creative, or consumer-facing apps
   • Corporate (Teal Green): For business, enterprise, or professional apps
   • Neutral (Gray + Red/Blue accents): For minimal, utility, or neutral apps
   • Custom: If client specifies specific colors/brand guidelines
5. Structure Data: Organize into PRD format with stable IDs
6. Validate Output: JSON must pass PRD Pydantic validation
7. Emit Result: Output pure JSON only

Design Preference Extraction

Look for these signals in the interview transcript:

Signal in Transcript	Recommended Preset
"modern", "innovative", "creative", "startup", "consumer app"	creative
"professional", "enterprise", "B2B", "corporate", "business"	corporate
"clean", "minimal", "simple", "utility", "neutral"	neutral
Specific hex codes, brand colors, style guide mentioned	custom
No preference mentioned	Default to corporate for internal apps, neutral for client projects

If the transcript mentions specific colors (e.g., "our brand color is blue #2563eb"), capture them in design_preferences.custom_colors.

Validation Requirements

• JSON must validate against PRDModel in app/models.py
• Feature IDs: FR-001, FR-002, etc. (never regenerate)
• Story IDs: ST-001, ST-002, etc. (increment only)
• All acceptance criteria must be testable
• Technical requirements must reference specific technologies
• Design preset must be one of: creative, corporate, neutral, custom

Consistency Rules

• Features must align with any existing ADR decisions
• User stories must map to specific features
• Non-functional requirements must be measurable
• Dependencies must be clearly identified
• Design preferences should align with project type and audience

Error Handling

If validation fails or inputs are invalid, output:

{
  "error": {
    "code": "PRD_VALIDATION_FAILED",
    "message": "PRD does not match required schema",
    "details": ["Missing required field: project_name"],
    "artifact": "prd",
    "remediation": "Fix validation errors and regenerate PRD"
  }
}

Example Usage

Use @agents/genesis/prd.md
transcript_path: @docs/interview/client_onboarding.md
project_name: E-Commerce Platform
owner_email: client@example.com

Human Approval Gate

After successful completion, this agent requires approval from:

• Cynthia (Product Owner) - Reviews features and design preferences
• Hermann (Technical Lead) - Reviews technical requirements
• Usama (Project Manager) - Reviews overall scope

Do not proceed to Flow design until explicit human approval is received.

Note: If design preferences are unclear from the transcript, the approvers should confirm or adjust the design preset during the approval stage. This prevents design misalignment later in the project.
