You'll notice
Artifact file listing and reading now include the artifact's declared type when the file is type-locked
What
When the artifact tool's list_files and read_file actions handle a file that is "type-locked" (tied to a specific artifact type), Claude Code now looks up that type's metadata and includes it as a type field in the response, alongside the existing from_type flag. The read action also now records type_named in its internal telemetry when the artifact has a title.
Why
This gives Claude Code more context about what kind of artifact a file belongs to when listing or reading it, which can help produce more accurate handling of type-specific files.
