Source code for url_content_extractor
"""URL Content Extractor Module.
Scans message text for supported URL types and returns extracted content as
system-injected annotations that can be appended to the LLM context.
Supported sources: Twitter/X, YouTube, GitHub repos/issues/PRs, arXiv papers,
Reddit threads, Wikipedia articles, GitHub Gists, Bluesky posts, Stack
Overflow/Exchange, NVD CVE entries, Spotify, SoundCloud, TikTok, Vimeo,
paste sites (Pastebin/Hastebin/etc.), and cryptocurrency price mentions.
Direct image URLs are downloaded as multimodal content parts, and any
yt-dlp-supported video/image URL is fetched (with disk caching, SSRF
guarding, and background downloads) and surfaced as both text annotations
and multimodal parts.
All extracted user-generated content is wrapped with
:func:`wrap_untrusted_data` to prevent prompt injection.
