AI Agent Skills: 6 Worth Installing First (Beginner's Field Guide)

Six AI agent skills worth installing first, explained for beginners — with one real use case each. Two cut what your agent costs (Defuddle, Caveman), three add abilities it doesn't have (Humanizer, Marketing Skills, Composio), and one makes it check its own work (Superpowers). Project pages (all free, open source): • Defuddle — github.com/kepano/obsidian-skills • Caveman — github.com/JuliusBrussee/caveman • Humanizer — github.com/blader/humanizer • Marketing Skills — github.com/coreyhaines31/marketingskills • Composio — github.com/ComposioHQ/composio • Superpowers — github.com/obra/superpowers These are project links, not ads or affiliate links. Star counts and features change often — check the live page before installing, and read a skill's file before you let your agent follow it.
