What
When you type a slash command Claude Code does not recognise, Claude gets instructions on how to reply. Those instructions used to say you could add the command as an organization plugin or a project skill.
They now:
tell Claude to use a skill of that name if one exists (a skill is a packaged set of instructions Claude can use)
suggest creating the command in claude.ai or the desktop app
end with "Do not say the command ran."
Why
This changes what Claude says when you use a command it does not know, and makes it clear the command did not run.
