- framework quality
- agent task success
- benchmark performance
- unique users
- non-npm installations
- commercial adoption
- developer satisfaction
Publication
All five activity measurements must be available for every reviewed project from the two official platform APIs.
Interpretation
The rank is npm activity within this exact cohort. GitHub stars, forks, and recency are separate context columns and are not combined into an opaque popularity or quality score.
