An agent skill that geolocates a photo with nothing readable in it — OSM geometry, elevation skylines and satellite tiles turn “where was this taken?” into a measured answer with an error radius.
geo-sleuth is a standard Agent Skill (SKILL.md plus ~20 single-purpose Python scripts) where the scripts search, score and sort and the model only judges among the top few. It is built for photos with no text, no plates and no landmarks: OpenStreetMap geometry, elevation data, satellite tiles and street view carry the search on their own. The README's showcase case is a stripped-EXIF phone photo of a rice paddy and a railway viaduct: pier spacing became a distance ruler, 27,335 OSM railway-bridge segments were scanned down to 171 candidate sites, 14,372 skyline-fit positions collapsed to 22, an overlay check and a 17-pier bearing intersection pinned one spot to ±2 m — about 72 minutes end to end. Every conclusion must name the command that ran and the file it produced; answers carry coordinates ± radius, camera heading, a satellite evidence image and a graded confidence. MIT, Python 3.10+, and the same folder runs in Claude Code, Codex, Cursor, Gemini CLI, OpenCode and GitHub Copilot.
Geolocation-grade photo forensics from a single image — verifying where a claim photo was shot, tracing landscapes for research or journalism, or exercising an agent on a long multi-step evidence task where every step must point at a file.

Runs are long: the showcase case took about 72 minutes, roughly half of it computation. Rulers rely on stated assumptions (the case assumed a 32 m pier span), and accuracy degrades where OSM or elevation data is thin — the answer's error radius exists for a reason. Geolocation is dual-use: locating people or sensitive sites from photos can cause real harm, so use it on lawful targets. MIT.
