Investigate whether one specific npm package is trustworthy — maintainer/ownership takeover signals, publish-provenance mismatches, and risky install scripts. Use when the user asks if a single named package is safe, compromised, hijacked, suspicious, or "can I trust this" — not for auditing a full package.json/lockfile (see dependency-audit) and not for a plain factual question like "what does X do."

# NPMScan package trust check

Use this skill when the user names **one specific package** (optionally a
version) and asks a trust question about it — "is X safe to use," "was X
compromised," "should I be worried about X," "check X's maintainers." This
is a deep, single-package investigation: it runs checks `dependency-audit`
deliberately skips for every package in a batch because they're too
expensive to run at scale.

If the user instead pastes a `package.json`/lockfile/dependency list or asks
to audit multiple packages, use the `dependency-audit` skill instead — don't
run this skill's checks across a whole inventory. If the question is purely
factual with no trust/safety angle ("what does lodash do," "what's the
latest version of express"), just answer directly with `get_package` — don't
