Questions

Claude Code skills, answered.

What are the best Claude code skills?

The list above starts with the ones people install most that already have a habit. Each card says what the skill does and what its habit does by itself.

What is the difference between a skill and a habit?

A skill works once, when you ask. A habit runs the skill by itself: it starts on a schedule or event, checks its own work and keeps notes.

How do I use these code skills?

Paste the setup prompt above into Claude Code, Codex or Cursor. Your agent then finds the right skill for each task.
