Skyptic: checking whether a moving dot in the sky is real
A tool that runs professional-style checks on suspected asteroid or comet sightings, with its engine written by Claude Code.

The full story
Skyptic takes measured positions (MPC or ADES format), FITS frames (still beta) or a plain description of a moving dot in the sky and runs checks: is it a star, a satellite, a known asteroid, do the points move like one object, does one orbit fit across nights, and could it be noise or a camera artefact. Each answer shows the number behind it and how often that verdict has been right.
Claude Code wrote the engine and wired each check to a public source, including MPC orbit files, Gaia DR3, CelesTrak, SatChecker, JPL Horizons, Find_Orb and digest2. The maker ran a main Claude Code session that steered many nested sessions, using different Claude models for the engine, research, design and reading screenshots.
