Create traceable PowerPoint briefs from Slack threads with Claude Haiku

## Turn a Slack thread into a PowerPoint file, with nothing the thread did not say Mention the app inside a Slack thread ("make slides for the weekly meeting"), or paste a conversation into the form. Claude fills a fixed outline — background, discussion points, decisions needed, next steps (who, what, by when) — and quotes the message behind every item. Code checks each item: the quotes must be in the conversation, every number and date must be written in the quoted messages, owners must be people in the thread. What fails is left out and listed in the reply. Code then writes the .pptx itself (Office Open XML, zipped by the Compression node). No Google or Microsoft account, no community node. The file is attached in the thread, or downloaded from the form. ### Setup 1. Credentials: Slack (bot token), Anthropic. 2. Slack app: bot scopes app_mentions:read, channels:history, chat:write, files:write, users:read; Event Subscriptions with the production URL of Slack mention, subscribed to app_mention. 3. List member IDs in Slack settings. Set fonts, accent color and labels in Config. Try the form first.
