3 use cases

  • Find where a photo without GPS was taken

    Give an agent a photo with no location data and get back camera position, heading and an evidence image.

    View prompt
    Use the geo-sleuth skill from the Oldcircle/geo-sleuth repo to find where <path to photo> was taken. Expect a camera position with an error radius, a heading, a satellite evidence image and a confidence grade. Verify that the conclusion names the commands run and the files they produced.

  • Match a mountain skyline to a power line site

    Use nearby power lines and the ridge line in a photo to narrow a location in a region.

    View prompt
    Use the geo-sleuth skill from the Oldcircle/geo-sleuth repo to narrow where <path to photo> was taken, using power lines and the ridge line in the photo. Expect a single candidate site with its fit score and a satellite image of the line of sight. Verify that the score and the files produced by terrain.py fit are cited in the answer.

  • Pin a city street photo using public street-tree data

    Use a city's open street-tree records and street features to find the block in a street photo.

    View prompt
    Use the geo-sleuth skill from the Oldcircle/geo-sleuth repo to find the block where <path to street photo> was taken, starting from public street-tree data for <city>. Expect a block with an error of a few metres and a list of the trees and checks behind it. Verify that each claim names the file or command that supports it.

How to use Geo Sleuth

  1. Check you have what it needs: An agent that reads SKILL.md and can run shell commands (the README names Claude Code, Codex, Cursor, Gemini CLI, OpenCode and GitHub Copilot); Python, since the scripts are written in Python; Node.js with npx, to run the install command (inferred from the npx install line).
  2. Open Oldcircle/geo-sleuth on GitHub and read the README and license.
  3. Run npx skills add Oldcircle/geo-sleuth and pick your agents when prompted.
  4. Ask the agent to run doctor.py from the installed skill's scripts/ folder and fix any failed checks. (inferred, check the README)
  5. Hand the agent the photo and say: find where this photo was taken.
  6. Read the returned coordinates, error radius, heading and evidence image.

These steps come from our top use case, Find where a photo without GPS was taken, which also has a copy-paste agent prompt.
