How does this skill deal with unstable GUIDs?

It implements detection logic to track GUID and enclosure URL pairs, using the enclosure URL as a secondary identifier to prevent duplicate episodes when GUIDs change.

What namespaces does this skill support?

The skill supports Standard RSS 2.0, the iTunes namespace (itunes:), and the modern Podcasting 2.0 namespace (podcast:), including transcripts and value tags.

How does it handle missing episode numbers?

It uses smart classification heuristics to infer season and episode numbers from title patterns (like S01E01) or publication date ordering.

Does it support chapter markers?

Yes, it handles both Podlove Simple Chapters embedded in the feed and Podcast Namespace Chapters provided via external JSON references.
