Plugin: MVP Launch

Analyze web app codebases against a battle-tested 10-point MVP launch checklist. Based on "Realistic MVP Launch Checklist (from building 30+ apps)".

/launch-check

The 10-Point Checklist:

1. Stripe Setup (webhooks, trials, failed payments)
2. Mobile-First Design (real device testing)
3. Smooth Onboarding (minimal steps, fast first win)
4. AI & Automation Stability (retries, error handling)
5. Critical Emails (welcome, trial-ending, failed payment)
6. Error Logging (catch bugs before users)
7. User Feedback Loop (simple form or tool)
8. Auth & Roles (secure pages, basic roles)
9. Custom Domain with SSL (no dev URLs)
10. Real Database & Backups (automated backups)

Philosophy: "Don't overbuild. Just make it stable, usable, and something people can trust."

See plugins/mvp-launch/README.md for full documentation.

Plugin: Product Management

AI-native product management for startups. Process signals, not features.

After installing, just ask Claude Code:

"Analyze my product"
"Research competitors"
"Find feature gaps we should build"
"What should we build next?"

Key Commands

/pm analyze     # Deep product understanding
/pm landscape   # Market overview + competitors
/pm gaps        # Batch gap analysis with WINNING scores
/pm file        # Create GitHub Issues for top priorities
/pm roadmap     # Organize into Now/Next/Later

WINNING Filter

Prioritize with objective scoring: WINNING = Pain × Timing × Execution

• 40-60: FILE (high conviction)
• 25-39: WAIT (monitor)
• 0-24: SKIP (not worth it)

spec-kit Integration

This skill handles WHAT to build (product discovery). For HOW to build, use spec-kit:
