Artifact type filtering switches from plain substring search to fuzzy best-match ranking
When listing Artifact types (categories used for shared Artifacts), the type_query parameter used to work as a simple case-insensitive substring filter. It now ranks results by how well they match and drops weaker matches instead of just checking for a substring. Claude is now instructed to only use this parameter when a previous listing without it indicated more types exist than were shown.
A fuzzy best-match search can find relevant types even when the query doesn't exactly appear as a substring, though it also means a narrowed listing might not show the entire catalog of types, since weaker matches are deliberately left out.
