Secret credentials may flow to a network call
2 flows detected: OPENROUTER_API_KEY. We can’t prove the destination matches the brand the credential belongs to.

You'll be asked for 2 credentials: ANTHROPIC_API_KEY, OPENROUTER_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
