LOW

Why flagged The npx command is used to run electron-builder locally as part of the build process for a project built from its own source; this is a standard and legitimate use in AUR packages, not execution of a remote untrusted package.

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-07-25) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The npx command is used to run electron-builder locally as part of the build process for a project built from its own source; this is a standard and legitimate use in AUR packages, not execution of a remote untrusted package.

1 higher static finding superseded - not the current verdict (shown for transparency)

MEDIUM npx/bunx/deno executes a remote package remote_code_tool

`npx`/`bunx`/`pnpm dlx`/`deno run <url>` downloads AND runs a remote package at build time — the moral equivalent of piping a download into a shell. Severity downgraded: Node.js consumer context.
