Clean duplicate and dead YouTube playlist videos with Slack reports

Quick overview This workflow runs weekly to scan a YouTube playlist, flagging deleted/unavailable/private videos and duplicate entries, optionally removing them from the playlist, and posting a cleanup report to a Slack channel. How it works Runs every week on a schedule trigger. Loads the target YouTube playlist ID, the dry-run toggle, and the Slack channel ID. Retrieves all items from the specified YouTube playlist and looks up each referenced video’s status. Classifies each playlist item as active or dead (deleted/unavailable/private) and flags duplicates by video ID while keeping the first occurrence. If dry run is disabled, deletes the flagged playlist items from YouTube in batches. Builds a summary of what was found/removed and posts the report to the configured Slack channel. Setup Connect a YouTube (Google) OAuth2 credential with permissions enabled to read playlists and delete playlist items as needed. Connect a Slack credential with permission enabled to post messages to your chosen channel. Set your playlistId, slackChannelId, and (optionally) dryRun in the workflow options before turning on the workflow. Requirements A Google account with YouTube access and an OAuth2 cr
