Partial The UI and decision flow are easy to vibe-code, but reliable hardware diagnostics across many laptop models and a bootable offline USB environment need systems-level expertise. The price-negotiation advice also depends on market pricing data.
What it would actually take: Build a bootable Linux live image (for example, Buildroot or a Debian-based ISO) that runs smartctl/NVMe tools, memtest, stress-ng, and sensor readers, with a simple UI that writes results to the USB. The hard parts are getting accurate battery-health and fan/thermal readings across vendors' firmware and interpreting them into a trustworthy score. That requires hardware and OS-level expertise plus a dataset of known-good and known-bad machines for calibration, and a pricing database for the bargaining recommendations.
