This is an agent skill (a SKILL.md) for verifying whether an image or video is authentic, original, and correctly captioned. It covers provenance checks, ELA, noise and compression analysis, clone detection, lighting/shadow consistency, C2PA credentials, deepfake and AI-generation tells, plus video container inspection via tools like ffprobe.

Use it when you need a structured, hypothesis-driven workflow for image or video verification rather than ad-hoc tool running.

Use it to

  • Fact-check a photo or video's origin and caption
  • Check footage for deepfake or AI-generation signs
  • Detect copy-move or splice manipulation
  • Test whether media is recycled or miscaptioned
  • Grade confidence per claim before publishing

For Fact-checkers, OSINT analysts, fraud and insurance reviewers
