Artifact quickstart gains a 'start kit' mode that saves type and design-system files to disk instead of reading them one by one
The Artifact quickstart flow has a new "start kit" mode. Instead of the model reading an Artifact type's and design system's files through repeated Artifact tool calls, this mode saves those files to a local scratchpad directory on disk and tells the model to read them all at once with a single tail -n +1 command in the Bash tool.
The mode enforces caps, refusing when there are "more than" a set number of files or when the total size goes "over the 8 MB total" limit.
Reading a batch of files from disk in one Bash call is faster and cheaper than making many separate Artifact tool reads, speeding up the start of an Artifact quickstart.
