You'll notice
Artifact tool's list_files/read_file summaries were similarly shortened, dropping detailed co-write and approval explanations
What
The short descriptions shown for the artifacts tool's list_files and read_file actions were also cut down to two brief, fixed sentences, replacing more detailed text that had explained co-writing, type-publisher distinctions, and approval scope.
Why
This matches the same simplification made to the artifact read/list-asset summaries, trading detailed explanation for shorter, simpler text shown to the reader.
