What this score measures

The Commit trust score measures behavioral commitment — signals that are hard to fake. Unlike stars, READMEs, or download counts, these signals capture how a package is actually maintained.

Longevity — how long the package has been published and actively maintained
Publisher depth — number of people with npm publish access (distinct from GitHub contributors)
Release consistency — regular releases signal active oversight
Download trend — growing, stable, or declining adoption
GitHub backing — contributor depth and OpenSSF Scorecard process security
Trusted Publishing — whether the package uses npm OIDC provenance to publish from CI, eliminating stolen-credential attacks
