What are you building?
Describe your app. x4 plans it, agents build it, ships it to production.

Your terminal just got a team.
Eight features. One command. Agents handle the rest.
The stack you would have chosen anyway.
Not scaffolded toys. Not locked-in frameworks. The exact tools senior engineers pick.
Shipped is never finished.
x4 scans what you've built and finds what's missing before your users do.
/x4:gaps
Dead ends. Missing connections. Incomplete flows.
- ●No error handling on /api/payments
- ●Profile page has no loading state
- ●Settings route unreachable from nav
/x4:dream
What if. What's next. What's emerging.
- ●[What if] Dark mode toggle
- ●[What's next] Stripe billing integration
- ●[Emerging] AI-powered search
Selected ideas feed straight back into /x4:work. The loop never ends.
Six specialists. One pipeline.
Each agent owns its domain. None can touch what isn't theirs.
API routes, database schema, tRPC procedures, server-side logic
React components, pages, styling, client-side state
Code review, architecture decisions, quality audits — delegates to Security Reviewer for sensitive changes
tRPC auth, session/token handling, API key exposure, input validation, CORS, SQL injection, XSS — auto-spawned by Reviewer
Unit tests, integration tests, E2E with Playwright
Bundle analysis, Core Web Vitals, query optimization
Ready to stop building manually?
Three commands. Your machine is ready. Your agents are waiting.
