What
Claude Code sorts shell commands into groups before running them, for example to decide how to treat them. When the shell is bash, this check now compares some groups against the command name exactly as written, not a cleaned-up form of it. The set of groups it looks at has also changed.
Why
In bash, how a command is classified can now depend on its exact spelling.
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 command groups changed or what the classification is used for.
