Building Composable AI: Why Skills Marketplaces Are the Next Package Managers

The software world solved dependency management decades ago. npm, pip, cargo — these tools transformed how we build by making code reusable and discoverable. But in the AI agent space, we are still in the pre-package-manager era. The Problem: Every Team Rebuilds From Scratch If you are building AI agents today, you have probably noticed the pattern. Your agent needs to extract data from PDFs? Build it. Summarize meeting notes? Build it. Generate domain-specific reports? Build it again.
