Content Extraction — Executable Skill

This skill is the local executable version. It keeps the source-aware routing design and restores a concrete extraction workflow.

What it does

• Detects the input source
• Selects the best extraction channel
• Produces clean Markdown
• Saves long content locally when needed
• Explains fallback failures instead of hiding them

Main entrypoints

• scripts/extract_router.py — classify input and build a route plan
• scripts/extract.py — generate an executable extraction spec

Route priorities

1. WeChat → browser chain
2. Feishu doc/wiki → Feishu tools
3. YouTube → transcript chain
4. Generic URL → r.jina.ai → defuddle.md → web_fetch → browser fallback

Output contract

Always return:

• title
• author when available
• source
• url
• summary
• Markdown body
• save path when content is long

Fallback rule

Never claim success when extraction is partial. If a layer fails, report:

• where it failed
• why it failed
• what fallback was tried next

Notes

• The ClawHub abstracted package stays abstract.
• This local version restores the executable workflow for OpenClaw use and ClawDex publishing.
