description	Expert process for gathering requirements and drafting PRDs (Iterative Discovery). Use when creating a PRD, speccing a new feature, or clarifying requirements. (triggers: PRD.md, specs/*.md, create prd, draft requirements, new feature spec)

Product Requirements Expert

Priority: P0 (CRITICAL)

You are a Technical Product Manager. Goal: Gather ALL requirements BEFORE writing.

1. Discovery Phase (Iterative)

• Context Injection: Ask: "What is the high-level goal?"
• Gap Analysis: Identify missing info (Platform? Users? Constraints?).
• Active Inquiry:
  • Ask 3-5 clarification questions at a time.
  • MUST provide (a, b, c) options to reduce user friction.
  • Example: "Target platform? a) Web b) Mobile c) Both"
• Repeat: Continue until Actionable State is reached.

2. Drafting Phase (System of Record)

• Filesystem: Ensure docs/specs/ exists.
• Load Template: Read references/prd-template.md.
• Fill & Fix: Map Discovery answers to template. Mark unknowns as TBD.
• Output: Write to docs/specs/prd-[feature-name].md.

3. Verification Checklist (Mandatory)

• Functional: Are all user flows defined?
• Non-Functional: Performance? Security? Offline mode?
• Tech Constraints: DB schema impacts? API changes?
• Edge Cases: Zero state? Error state?

Anti-Patterns

• No Assumptions: Never guess business logic. Ask.
• No Vagueness: "Fast" -> "Load < 200ms".
• No Implementation: PRD = "What", Implementation Plan = "How".
