Individual skill

where-was-this-taken

End-to-end workflow to establish where and when a photo or video was captured and whether it is authentic — evidentiary handling, metadata extraction, reverse image search for provenance, visual geolocation, chronolocation from shadows, and manipulation checks, ending in a location finding with a stated confidence radius. Use when asked to verify where an image was taken, confirm or refute a claimed location or date, or authenticate media before relying on it. Applies to insurance claims, litigation evidence, disinformation analysis, and conflict and human-rights documentation. Reference at useosint.com/skills/where-was-this-taken.

# Where was this taken

Input: an image or video file, or a URL to one. Output: a location with a confidence
radius, a time window, an authenticity assessment, and the evidence chain for each.

This workflow orchestrates. The technique detail lives in `secrets-in-file-metadata`,
`find-the-original-image`, `geolocate-from-pixels` and `is-this-photo-real` — run
those, don't reimplement them here.

The order matters more than anything else in this file. Metadata before analysis,
because analysis destroys metadata. Provenance before geolocation, because the
original's caption often *is* the location. Authenticity checks before you commit,
because geolocating a composite gives you a confident answer to the wrong question.
