Internal Changes Section of the release
What
Claude Code's shared team memory and mounted-directory storage can now fail in a much wider variety of clearly named ways, including:
team_memory_too_many_entries, team_memory_entry_too_large
team_memory_group_acl_denied, team_memory_group_acl_unconfigured, team_memory_feature_unavailable
mount_dir_foreign_partition, mount_dir_unmanifested_nonempty, mount_dir_unreadable
store_full, content_too_large, content_secret, content_screened
index_too_large, invalid_path, store_archived
Why
A larger, more specific set of error codes means Claude Code can explain more precisely what went wrong when a team memory write or mounted-directory access fails, instead of a generic failure.
