Stethoscope

Check the health of a github repo with one easy step.

Features & Capabilities

When you go to a github repo, the extension will check for various things on that page and give a score/grade. It is not meant to make the decision for you, it is just a quick assessment.

For the time being it only works on the English version of Github, but we hope to internationalize at some point soon.

Here is some of the criteria we look for. It is important to note that missing some of these is not a huge problem. They add up in total to more than 100% of a possible score. So, one missing can still allow a perfect grade.

  • Has License file or section in the README. It is an immediate fail if no license is found.

  • Stars count being above 100.

  • Has Readme file.

  • Most recent commit. Scaled to within a year. 1 year ago being a 0 and now being a 20.

  • Amount of contributors being greater than 5.

  • Amount of commits.

  • Has a sponsors section.

  • Has a releases section

  • Has docs folder.

  • Frequency of commits for root level files and folders. Checks amount of time between most recent and oldest. Also checks for varied dates between and ratio of unique commits.

  • Open issues relative to star count or commit count, whichever is greater.

Is Stethoscope Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Stethoscope requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Stethoscope is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
