What
Claude Code has a fallback way of matching commands that looks at the individual words of a command line. This fallback now ignores any configured command whose name contains a space.
Why
A single word can never match a name made of several words, so those names are left out of this check. Multi-word command names are no longer handled by this fallback.
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 feature relies on this matching helper.
