Summary ⤵️
Claude Opus 4.8 just dropped — and I used two of its most powerful new features (ultracode +to dynamic workflows) build a fully functional AI Operating System in under 15 minutes. No database. Minimal human input. Just Claude doing the heavy lifting.

This AI OS (agentic OS) tracks industry trends, competitor content, YouTube stats, social media metrics, and active projects — all from a single dashboard. And yes, you can sell this to clients.
