Building an autonomous multi-agent SEO system with Claude + GitHub Actions ("cheap" and quick)

I needed SEO content for a Chrome extension I built. The arithmetic of doing it myself was discouraging: six to eight hours per post if I wanted it to be good, plus another two for translations into Catalan and Spanish (I know, I know). I was not going to write four posts a week. I was not going to write one post a week reliably either. I knew AI Agents could come to the rescue, but those usually require an expensive token economy. and I'm on a budget, so I had to find creative ways to get the work done without breaking the bank. So I came up with a system that does it.
