Does kcap require any external tools?

kcap utilizes common CLI tools like trafilatura, yt-dlp, and bird-cli for extraction; the skill provides setup instructions if these dependencies are missing.

How does kcap protect against prompt injection from websites?

kcap uses a dual-agent pattern where a privileged main agent handles file operations while a separate, sandboxed synthesis agent analyzes the content without execution permissions.

What is the difference between Standard, Deep, and Full modes?

Standard provides a concise summary, Deep offers extended analysis with counterarguments and action items, and Full performs content cleanup to save the original text without summarization.

Can I save notes directly to my Obsidian vault?

Yes, you can configure a custom output path to your Obsidian vault and enable Obsidian URI integration to open notes automatically after capture.

What types of content can kcap capture?

kcap supports a wide range of content including standard HTTPS web articles, YouTube video transcripts and metadata, and Twitter/X threads.
