Why this score

This repo hosts 10 skills, so its 49,369 stars are split between them (about 4,937 each) for scoring.

Popularity score: 86/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank

What its code does:

• Reads environment variables and sends network requests with them API clients do this to send your key to the service. Check which service it talks to.
• Runs shell commands Common for dev tools. Read the commands it runs.scripts/retry_elsevier_api.mjs:5 and 1 more
• Runs code it builds while running (eval or exec) Harder to read ahead of time, since the code is assembled while it runs.scripts/lib/cdp-utils.mjs:12
• Makes network requestsSKILL.md, scripts/configure_credentials.py:96, src/validators.py:71 and 6 more
• Uses dependencies without a pinned version A later version of a dependency could change what runs.requirements.txt:1 and 3 more

These are the sites named in the code, so it's where your data could go. It isn't a complete list: code can build addresses while it runs, and a few of these may be links rather than calls. Whatever you send also goes to the AI model you use.

A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
