Product Requirements Skill

When to Invoke

• Says "I want to build...", "Let's build...", "Create a..."
• Asks "Create a PRD", "Write requirements", "Plan this feature"
• Mentions "product requirements", "PRD", "epic roadmap"
• Has completed discovery phase and needs formal requirements
• Is starting a Level 2-4 project requiring structured planning
• Uses words like: build, create, PRD, requirements, plan, feature, product

• "I want to build [something]"
• "Create a PRD for [project]"
• "Plan this feature"
• "Write the requirements"
• "What should be in the PRD?"
• "Break this into epics"
• "Product requirements for [project]"

• If Level 3-4 project: verify analysis phase complete (discovery brief exists)
• If missing analysis: recommend invoking bmad-discovery-research first
• If Level 0-1: suggest OpenSpec workflow instead

• User is still exploring/brainstorming (use bmad-discovery-research first)
• User is ready for architecture (use bmad-architecture-design instead)
• User wants to code directly (check if prerequisites exist first)
• Project is Level 0-1 simple change (use OpenSpec)

Mission

Inputs Required

• business_goal: clear outcome statement tied to measurable success metrics
• stakeholders: decision makers plus their approvals or open concerns

Process

1. Validate readiness using the gate in

   CHECKLIST.md

   .
2. Review discovery inputs and clarify remaining unknowns.
3. Map goals, scope, and constraints into structured PRD sections.
4. Prioritize epics, sequencing, and acceptance signals for delivery.
5. Run

   scripts/generate_prd.py

   when structured data exists; otherwise compose outputs manually following templates.
6. Apply the quality checklist before returning deliverables and recommended next steps.

Error Handling

• Identify which required input is absent and why it blocks progress.
• Provide a minimal list of follow-up questions or stakeholders needed.
• Recommend re-engaging the discovery-analysis skill or orchestrator when scope is unclear.
