A skill is one more ability for your Claude
By default, Claude is an excellent generalist. But the moment you want it to analyze a database, browse the web for you, draw diagrams or stop writing like a robot, it needs a hand.
That's where skills come in. They're packs of abilities you install once, and that Claude loads on its own when the context calls for it. You no longer have to re-explain everything in every conversation.
This list contains the 9 resources I keep on hand: official skills, open source libs and serious docs to turn Claude into a real operational assistant.
The Claude AI Lab is my Skool community where I share my Claude systems and the more advanced modules. Entry is free.
Join the Lab →Pick from the list based on your need. No point installing everything at once. Start with 1 or 2 skills that match your current workflow, test them for a week, then stack more.
stop-slop
Anti-slop skill: detects and rewrites AI writing patterns so your text sounds human. Essential if you publish content drafted with Claude.

Evaluating Skills with MLflow
The go-to article for understanding how to test and evaluate the quality of your skills before deploying them. Useful as soon as you start building your own.
Skills load into ~/.claude/skills/ (Claude Code) or via the Skills menu on Claude.ai. A git clone and you're set. Install 1 skill, test it for 24h. You see the difference, you stack another.
