What
Plan mode is a permission mode in which Claude works out a plan before it changes anything. When Claude Code starts, it decides which permission mode to use.
With a permission mode flag on the command line, that flag still decides.
When resuming a session and no flag is given, Claude Code can now use a plan mode saved for that session.
Before, the mode came only from the command-line flag.
Why
A session you pick up again may go back into plan mode on its own, so Claude may plan first instead of making changes straight away.
