You'll notice
Claude Code now skips YAML-like front matter when picking a title for a markdown artifact
What
When Claude Code needs to pull a title out of a markdown document (used for naming artifacts), it now recognizes and skips over leading lines that look like YAML front matter, using a new pattern match, before it looks for the actual heading. Previously it only skipped blank lines and HTML content at the start of the document.
Why
Markdown files that start with a front-matter block (key: value lines before the real content) will now get a sensible title pulled from the first real heading instead of from the front matter itself.
