How the command menu matches what you type

Claude Code filters the / menu as you type. Each bullet below covers one thing you might notice while filtering:

• Highlighting: Claude Code highlights the top suggestion only when the letters after the / match a command's name or alias, from the start of the name or from a word within it, ignoring the :, _, and - separators. Typing /adddir highlights /add-dir, and typing /new highlights /clear through its alias. Press Enter to run the highlighted suggestion. These highlighting rules require Claude Code v2.1.236 or later.
• After a typo: Claude Code highlights nothing. The close matches stay listed, and you can pick one with Tab or the arrow keys, but Enter submits your text as typed and reports Unknown command.
• Commands that aren't available to you: Claude Code leaves them out of the menu. When nothing matches, Claude Code shows No commands match "/name". Most unavailable commands return Unknown command when you submit them; a few, such as /schedule on a Console API key, answer with their own availability message instead. Some commands also answer with a message of their own when your organization's policy disables them.
• Hidden commands: Claude Code keeps a few available commands, such as /heapdump, out of the menu by design. A partial name never brings a hidden command into the menu: if the partial matches nothing visible, Claude Code shows the same no-match message. Claude Code lists the command only once you've typed its full name, and submitting the full name runs it.
