Individual skill
geo-sleuth
Geolocate or chronolocate a photo with tool-verified reasoning, then route every output into the case's EV-NNNN evidence chain. Companion to the upstream Oldcircle/geo-sleuth agent skill (MIT): its scripts do metadata, OCR, reverse image search, sun/shadow math, OSM corridors, DEM skylines and street-view ranking. Use when: "where was this photo taken", "geolocate this image", "when was this taken", "chronolocate", "find the location of this picture". NOT for: identifying a person in a photo (use /q-face, founder approval required), or photos of private individuals whose location the case has no lawful reason to find.

# geo-sleuth (Investigators Copilot companion)
Adapted from https://github.com/Oldcircle/geo-sleuth (MIT, see `NOTICE.md`). This
file does NOT vendor the upstream scripts. It tells you how to install them, the
rules that make their output defensible, and how to land every artifact in the
case's evidence chain under `.claude/rules/evidence-capture-protocol.md`.
## 0. Gate before you start
- **Purpose check.** If the photo shows a private residence, a minor, or a person
who is not a case target, stop and ask the founder what the location is for.
Upstream's own rule: never use it to find people who have not agreed to be found.
- **Register the photo first.** A client-provided photo becomes an EV item before
any analysis touches it:
