Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
notify-sounds
Plays system sounds in Claude Code when a task finishes or when permission is needed, so you don't have to keep watching the terminal. Cross-platform: macOS (afplay), Linux (PulseAudio/PipeWire), Windows (PowerShell SoundPlayer), with terminal-bell fallback. Sub-agent stops are skipped to avoid noise during multi-agent workflows.
Heard
Let cloud agents talk to you: progress updates spoken on your Mac, and replies you send back.
