Unclear What difference the new check makes in practice is not known.
What
A flag is an option you add when starting claude. Claude Code now checks the --safe-mode flag with the same routine it already uses for --restricted and --strict-mcp-config. The check now runs when it is needed rather than once up front.
Why
This could change how --safe-mode is handled in some situations.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Confirmed sinceAnthropic's documentation has since written up --safe-mode, on Debug your configuration.Start with [`claude --safe-mode`](/docs/en/cli-reference#cli-flags), which launches a session with your customizations disabled, including:debug-your-configsee the edit
Confirmed sinceAnthropic's documentation has since written up --restricted, on Claude Code changelog.* Fixed `--tools` and `--restricted` not applying to built-in tools that register after launch, and deprecated tool names reaching tools outside the caller's tool setchangelogsee the edit
