Under the hood
Artifact-type telemetry now distinguishes a proper capabilities declaration from a missing or malformed one
What
When Claude Code describes an Artifact type internally, the telemetry it records now classifies the type's capabilities value into one of three states: not present, a valid capabilities object, or malformed. A new declaration field is included in the recorded detail when it's defined.
Why
This should make it easier to notice and diagnose Artifact types with broken or malformed capability declarations, rather than lumping them in with types that simply have none.
