Responsible use
ShipSleuth is a calculator, not a judge.
ShipSleuth helps people read public GitHub activity. Users can optionally supplement with self-reported private stats, but the tool does not verify those claims or measure total company quality or individual employee performance.
Short version
Use ShipSleuth as a diligence aid, not a verdict. It is best at making visible public GitHub activity easier to inspect and compare.
Context matters
Public GitHub signal can be useful. It can also be incomplete or misleading without context. Private work, stealth products, enterprise customers, regulatory constraints, monorepos, automation, and repo structure all affect what is visible.
Users can optionally enter self-reported private activity (commits, PRs, repos, releases, active days, lines changed) to get a more complete analysis. These values are clearly labeled as self-reported and are not verified by ShipSleuth.
