Spark CLI Skills 1.2.2

Updates the use-spark base skill to Spark CLI 1.2.2, brings the Spark CLI to Windows, and ships a new recipe.

Platform

• The Spark CLI is now supported on Windows, in addition to macOS.

Changed commands

• draft - added --attach-stream to attach a file piped from stdin (the inbound twin of attachment --stream), for files the app can't read from disk. The output now surfaces a Spark deep link that opens the draft directly.
• comment - added --attach-stream to attach a stdin-piped file as its own comment message.

New skills

• recipe-unsubscribe-audit - full unsubscribe audit: scan inbox, archive, and GateKeeper for newsletter senders, classify by volume and engagement, flag phishing and duplicate subscriptions, then unsubscribe via spark action or extracted footer links. Contributed by @quser.
