Why flagged

The npx commands are used to build the project's own frontend from source during packaging, not to execute arbitrary remote code; the source is from the project's GitHub repository and the build process is standard for Electron apps.

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 commands are used to build the project's own frontend from source during packaging, not to execute arbitrary remote code; the source is from the project's GitHub repository and the build process is standard for Electron apps.

1 higher static finding superseded - not the current verdict (shown for transparency)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