What
The --await-claim flag, an option typed on the command line, starts a spare session that waits to be given a project. The permissions.blockFileToolReadsOutsideWorkingDirectories setting lets Claude read files only in the folders given at launch. A spare session is launched before its project is known, so the two do not fit together. Claude Code now stops with an error when both are used, and tells you to start the session in its project's folder instead.
Why
If you combine these two options, startup now fails outright, so scripts or setups that use both need to change.
