A Claude Code skill turned their newsletter into a two-minute job
Writing a weekly newsletter kept losing out to more urgent work. A Claude Code skill now reads new blog posts, drafts the email in the writer's own voice, and creates the broadcast in Kit once it's approved.

Result Some months got zero newsletters; now one goes out weekly
“Before this setup, I sent maybe 2 newsletters a month on a good month. Some months I sent zero. Now I send every week because there’s no friction.”

What they did
They built a Claude Code skill that reads their site’s content index for posts published in the last 7 days, drafts a short newsletter in their own voice for each one, and shows them the draft before touching anything else. Once they approve it, the skill creates the broadcast in Kit through its API and can schedule it for a time they give it, such as “Tuesday morning”.
How it went
Running the skill takes about two minutes, compared with the 30+ minutes newsletters used to take to write by hand, and half the time they simply weren’t sent at all. Before the skill they sent maybe 2 newsletters on a good month, some months zero; since setting it up they send one every week.
Try it yourself with Claude Code
Write a [Claude Code] skill (a markdown file in .claude/skills/) that reads your site's recently published posts, drafts a short newsletter in your own voice for each one, and shows you the draft to approve before doing anything else. Once approved, have it create the broadcast in your email platform's API (such as Kit) and ask whether to schedule it for [a day and time] or leave it as a draft.

A side project needed a launch video, but not an agency's bill. Claude Code built one from the codebase plus their feedback. It took a lot of iteration over 2-3 days, all on subscription token usage.
About 15k pages of discovery stood between a solo practice and a summary judgment motion. Claude ran OCR, built embeddings and search scripts, then found evidence for each assertion, with traces to check.
Markdown files should just open, so they asked Claude Code for a viewer. It opens instantly: faster, they say, than any other macOS app, and faster than Bitwarden's Chrome extension shows its fill menu.
Migrating a password reset flow, Claude Code and Opus produced code on par with a mid level developer. It needed close supervision throughout, and cost roughly 2 months of Pro subscription for about half a day's work.
A URL shortener side project ran on AWS. Claude Code wrote the GitHub Actions workflows for the move and fixed each failure as it came up. The writer reports zero downtime.
A 7-app monorepo needed an 8 GB memory setting and 25 seconds to typecheck. Claude Code made the changes for the move to oxlint, oxfmt and tsgo, and the team validated each step.
