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
tts-attention-alert
Windows-only attention alerts for AI coding agents. When the agent pauses for permission, asks a question, or finishes a response, the plugin speaks the notification out loud (TTS) and pulses a colored frame around your primary monitor — gold for blocking events, escalating to orange and red if you don't respond within 20s and 40s. Stop events get a calmer blue 3-pulse. Auto-ducks Spotify, YouTube, VLC, and other media apps around the spoken phrase so the alert is audible even mid-song, then resumes them. A forensic log of every event is written to ~/.claude/cache/notifications.log so you can scroll back what fired while you were away. No external dependencies — pure System.Speech.Synthesis, WPF, and WinRT GlobalSystemMediaTransportControlsSessionManager.
Alphorn
Let AI agents notify you on Slack, Telegram, email, SMS, or push via an Alphorn webhook.
