What
Slash commands are the commands you type after a / in Claude Code. Some are marked hidden, which means they exist but are not shown in lists. When Claude Code looks for the command that matches a name, it now also accepts a match when that command is hidden (Ye.isHidden). Before this change, a hidden command could not be the match in that check.
Why
If two commands have the same name and one of them is hidden, the hidden one can now be the one that runs. If a command behaves differently from what you expect, a hidden command with the same name may be the cause.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say which commands are hidden or how two commands end up sharing a name.
