⚠️ Security warnings before use:

• Files over 50 MB require --confirm-upload to upload to public third-party hosts (tmpfiles.org, transfer.sh)
• Browser cookie access ( --cookies-from-browser) exposes active session tokens for any platform you're logged into
• Never use with private, paid, confidential, copyrighted, or regulated content unless you explicitly intend external transmission

How It Works#

1. User shares a URL from any supported platform
2. Run the extraction script
3. Script downloads the media (or just analyzes it)
4. Returns the file path (under 50 MB) or a cloud link (over 50 MB)
5. Agent sends the media to the user

⚠️ Before any extraction: Confirm the content is not private, paid, or sensitive. Files over 50 MB are uploaded to public temp hosts — the script now shows a pre-upload warning and supports --no-upload to skip it entirely.

node skills/clip/extract.js "https://www.instagram.com/p/abc123/" --title

Supported Platforms#

yt-dlp: 1,872 extractors — covers essentially every major media platform on the internet.

Quick reference (most common):#

YouTube, TikTok, Instagram, X/Twitter, Facebook, Reddit, Twitch, Vimeo, Dailymotion, Rumble, Peertube, Bilibili, Niconico, SoundCloud, Bandcamp, Pinterest, Imgur, Tumblr, Flickr, Bluesky, Telegram, Kick, Odysee, CNN, BBC, Al Jazeera, TED, Khan Academy, Udemy, Crunchyroll, HiDive, and 1,800+ more.

File Size Handling#

• Under 50 MB → Returns local file path (agent sends via chat)
• Over 50 MB → Requires --confirm-upload to upload to temp cloud storage, returns download link
• Over 50 MB without --confirm-upload → Returns local path only, blocks upload with clear message
• Over 50 MB + --upload → Forces cloud upload even for smaller files (still requires --confirm-upload)

Cloud Providers#

⚠️ Both providers are public and third-party. Uploaded files are accessible to anyone with the link.

Pre-upload warning: Files over 50 MB require --confirm-upload for any public cloud upload. Without it, the script returns the local path only and blocks the upload with a clear message. Use --no-upload to always save locally without prompts.

Authentication#

⚠️ Browser cookie access exposes active session tokens for every platform you're logged into.

Some platforms require cookies for full access:

PlatformNeeds cookies?InstagramSometimes (private content, full resolution)X / TwitterSometimes (rate limits, some content)PatreonYes (paid content)OnlyFansYesFanvue / FanslyYesNetflix / HBO / Disney+Via browser cookiesYouTubeRarely (age-restricted content)

If cookies are needed:

• Use --cookies-from-browser chrome as a last resort — it exposes ALL platform session tokens in that browser
• Warn the user that this could enable unauthorized account access if the machine is compromised
• Prefer manual cookie paste or API keys when available
• Never use --cookies-from-browser with paid/sensitive platforms unless the user explicitly consents to the risk
• Consider exporting cookies from only the specific browser/profile needed, not the default one

How It Works (Under the Hood)#

1. Analyze: yt-dlp --dump-json detects the platform and media type
2. Download: yt-dlp -o <path> grabs the highest quality version
3. Route: Under 50 MB → return path. Over 50 MB → upload to cloud → return link
4. Fallback: If download fails, returns title/description so the agent can inform the user

Dependencies#

• yt-dlp (installed) — 1,872 extractors
• ffmpeg (installed) — format conversion
• curl (installed) — cloud uploads

Error Handling#

When a URL returns no media, the script returns the title/description. The agent should:

• Inform the user what was found
• Suggest trying --cookies-from-browser chrome if the platform may require auth
• Note that geo-blocked content cannot be bypassed

Notes#

• Rate limits may apply on some platforms — add delays between calls
• Some platforms (Instagram, X) work better with cookies
• If a URL returns no media, return the title/description to the user instead
• The generic extractor handles many embedded video players not explicitly listed
