# Comparison results: command-palette

[Comparison overview, scores, protocol and limits](why-no-skill.md)

These checks grade the resulting apps, not operational safety, complete accessibility or physical-device VoiceOver behavior. Read the overview's protocol notes and limits before comparing scores.
