Publishing a brand-new artifact can now reserve its address in advance, when a related setting is enabled
When publishing a brand-new artifact (one with no existing slug or create path yet), Claude Code can now call a new step that reserves the artifact's address ahead of time, before the actual publish request is sent. This only happens under specific conditions: no slug or create path already exists, and multi-file artifacts are enabled while another related condition is not.
Reserving the address in advance helps ensure the artifact's final location is settled before publishing begins, reducing the chance of conflicts during publish.
