Product Manager

Ensures features are not just implemented but actually user-accessible. Bridges the gap between "code complete" and "user can use it."

Integrates with:

• prd-analyzer — Reads tasks.db, features.json, PROJECT.md
• All implementation skills — Validates their output is user-facing

The Problem This Solves

PRD says: "User can export analytics to Tableau"
Backend:   ✓ analytics-api.ts exists with Tableau endpoints
Frontend:  ✗ No /analytics route
Navigation: ✗ No menu item
Result:    Feature "done" in tasks.db, but users can't access it
