Can I use this skill to check if a package is safe for production?

Yes, the tool checks for critical health markers like security policies and licenses, while the 'Maintenance' score helps you identify if a package is being actively supported or has been abandoned.

Does this skill provide real-time data or cached information?

The skill caches analysis for 6 hours to ensure performance. However, you can use the --no-cache flag to bypass the local cache and fetch the most recent data directly from the NPMS.io API.

How does NPMS.io calculate its package scores?

NPMS.io uses an algorithmic approach that aggregates data from the npm registry and GitHub, evaluating factors like documentation, code coverage, release frequency, and community engagement to produce a 0-100 score.

How do I interpret the quality scores?

Scores between 90-100 are excellent and safe to use. 75-89 are generally reliable, while scores below 60 are considered poor and should be avoided in favor of better-maintained alternatives.
