Skills your team can write, share, and run

A skill is a reusable procedure your agents can execute — packaged, versioned, and stored as a real bundle rather than a prompt someone pasted into a doc. Author one in chat or from Claude Code with create_skill, share it into a brain, and anyone who can reach that brain can run it.

Skills stage into the code-execution sandbox by name, so chat can load the right one for the task instead of improvising. Built-in skills are preloaded for everyone.
