content-summarizer

To summarize web pages and YouTube videos, this skill detects uncommitted markdown files, extracts source URLs from frontmatter, fetches content via WebFetch or transcripts, and generates structured summaries with metadata.

Extracting YouTube transcripts into structured notes is done by detecting uncommitted markdown files containing video URLs in frontmatter, fetching the transcript, and generating a reviewed summary directly in the file.

No external dependencies are required to start summarizing markdown. The skill fetches web content via Firecrawl or WebFetch and YouTube transcripts natively, requiring only uncommitted markdown files with source URLs in the frontmatter.

Frontmatter updating occurs after a review step where the skill performs fact-checking and supplementation. Once confirmed, it gracefully updates both the frontmatter and the markdown body with the structured summary and metadata.

You can review and fact-check summaries before committing because the skill includes a review step that performs fact-checking and supplementation, updating the markdown file only after optional user confirmation.

Uncommitted markdown files may not be detected if they lack a valid source URL in the frontmatter. The skill requires frontmatter URLs to fetch web content or YouTube transcripts for summarization and graceful error handling.
