Draft and schedule a weekly newsletter
Observed in the wild: sid wrote a Claude Code skill, a markdown file, with a Kit v4 API key kept in .env. On /newsletter it reads the site's content index for posts from the last 7 days and sketches a short email powered by his voice rules. The whole run takes about two minutes, down from 30+ minutes by hand.

Why it matters
Email is where a lot of admin quietly piles up. An agent that can read, sort, draft and follow up turns an inbox from a to-do list into something closer to a summary. It is one of 106 sightings filed under Email & Inbox on Agent Sightings (number 84 by interest), and one of 164 involving Claude Code.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude Code or any similar agent and adjust the details to your situation.
Go through my mail for this goal: draft and schedule a weekly newsletter. Propose labels, drafts, and unsubscribes as a checklist; change nothing until I approve.
Tip: Start with read-only access or 'draft, don't send', and check a few drafts before trusting it to send anything.
