LOW

Why flagged The flagged 'npm/yarn install' is part of building the project from its own source (cloned from the official GitHub repo), uses locked versions, and installs only declared devDependencies; no remote code execution or malicious payloads are present.

Triggered rules

LOW AI review downgraded a static finding llm_review

The static rules flagged this MEDIUM, but an AI model (qwen/qwen3-235b-a22b-2507) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The flagged 'npm/yarn install' is part of building the project from its own source (cloned from the official GitHub repo), uses locked versions, and installs only declared devDependencies; no remote code execution or malicious payloads are present.

1 higher static finding superseded - not the current verdict (shown for transparency)

MEDIUM npm/yarn/pnpm install of an undeclared external package npm_install_external

Runs `npm/yarn/pnpm install <package>` for a package not in source=(), pulling unpinned, unreviewed code at build time. Severity downgraded: the package declares/looks like a Node.js consumer, where build-time installs are expected.
