You'll notice
More bash variable and config key names are now protected from being overwritten
What
The list of protected bash shell variable and configuration names grew to include:
BASH_MONOSECONDSBASH_TRAPSIGBASH_SOURCE_PATHbash_cmdsbash_aliasesexecignorebash_source_path
Why
Protecting these names prevents Claude Code, or commands it runs, from accidentally overwriting bash internals or configuration keys that could break shell behavior.
