Claude skills and agent skills: what they are, and how to install them
A Claude skill (the general term is agent skill) is a folder with a SKILL.md file: instructions, and sometimes scripts or resources, that an agent loads only when the task calls for it, instead of sitting in context on every turn. Every skill below links to its real source and the exact command that installs it, verified against the client it actually works with.
