Show HN: Bullshit Detector – agent skills that fact-check videos and articles

A developer has created Bullshit Detector, an open-source tool that uses AI agent skills to fact-check videos, articles, and other online content by providing claim-by-claim verification reports with sources and a "BS score" (0-10). The skills are portable and work across multiple AI platforms including Claude Code, and can be installed either as copyable files or as a Claude Code plugin that auto-updates.
