def self.skills_adapter(model = nil)
  return Riffer::Skills::XmlAdapter if model && ANTHROPIC_MODEL_PATTERN.match?(model)
  Riffer::Skills::MarkdownAdapter
end

Bedrock hosts models from multiple vendors. Anthropic models prefer XML-rendered catalogs; everything else falls back to the default Markdown adapter.
