Opc

A full team in a single Claude Code skill. You're the CEO — OPC is everyone else.

21 built-in roles (PM, Designer, Security, Devil's Advocate, and more) that build, review, and evaluate your code through a digraph-based pipeline with code-enforced quality gates.

What you can build

From a single one-line brief, OPC's build-verify flow ships a complete, production-quality product — design tokens injected and visual quality validated by the design-intelligence extension. Every screenshot below is a real, clickable site (not a mockup), built by the same 21-role pipeline. Same system, six completely different design languages.

Each card in the lookbook flips on hover to reveal the exact prompt that built it — e.g. Pulse came from one line: /opc build a production-quality SaaS analytics dashboard called "Pulse"...

OPC isn't only for UIs. The same zero-trust pipeline also handles:

• Whole products, unattended — /opc loop build features F1–F4 from PLAN.md decomposes the work, schedules a durable cron, and runs 10+ hours without you.
• Code review — /opc review the auth changes dispatches 2–5 independent role agents (security, backend, a11y, devil's advocate) in parallel and computes a mechanical verdict.
• Full-stack features — /opc implement user auth with email/password runs build → independent review → test-design → test-execute → gate.
• Pre-release audits — /opc verify before release runs acceptance + audit + e2e gates before you ship.

How It Works

One principle: the agent that does the work never evaluates it.
