Summary

Melvin argues that agent skills are the future: modular, on-demand packages that give a coding agent deep context for complex development, beyond simple code completion. He started skillsbento.com, a free, open-source collection of agent skills. He also quotes a post announcing an "Intro to Agent Skills" video.
