My family’s accounting firm runs a small machine of its own: articles, carousels, a video archive, contact buttons that count, and a search report twice a month. Agents write most of it. I keep the rules, and a person approves anything that goes out. Scroll through two example weeks.

    A topic is due

    Two practical pieces a week and a roundup on Friday, chosen from what businesses actually search for and researched in official sources: the federal gazette and the tax and social-security authorities. The 1st and the 15th belong to the search report.

    drafted by agents

    Same morning

    Agents draft it

    An article in Markdown, a carousel, a story and two captions, written by agents from rules kept as skills. The article builds into a plain static page.

    • 1080 × 1350, every slide
    • Story at 1080 × 1920
    • Narrative order
    • Sources on the last slide
    • Text contrast

    Ready for a person to look at.

    Before anyone looks

    The audit runs

    Size, slide order, sources and contrast are checked by a script. A failure blocks the delivery instead of becoming a note for later.

    A person decides

    Nothing after this point happens on its own. The website needs a merge; the posts need the next step.

    Same day

    Publishing is run by hand

    The workflow only validates unless PUBLICAR is typed, exactly. It checks the slides, the permissions and the account first. On the Meta side there is one business app and a system user with six permissions: no messages, ads, payments or full control. Revoke it, delete the secret, turn off the workflow, and it all stops.

    one post, every photo

    A minute later

    The posts go up

    Instagram gets one item per slide, then a carousel that is checked until Meta reports it finished. Facebook does not copy a post made this way, so the slides go up as unpublished photos and become one post. The story’s link sticker is still added by hand, on a phone.

    Someone gets in touch

    WhatsApp is a click-to-chat button, not a bot. Every contact is counted by channel and by the page it started on, with nothing the visitor typed; campaign tags travel with the form.

    The report comes back

    A scheduled job reads Search Console with an account that can only read, writes the report and a memory of what was tried, then opens a branch and an issue. It never merges itself, and it judges a page by the contacts it starts.

    The video archive

    Sapiencia is the firm’s video talk show. Its episodes were imported from the public channel, sorted into seven subjects and given a short note and three questions to listen for, then turned into pages with privacy-friendly embeds.

A static site in plain HTML and Tailwind, Node scripts for every build and audit, GitHub Actions for publishing and the search report, Vercel for hosting. Two coding agents, Claude Code and Codex, share one skill that a script keeps in sync.

That any of this brought in a client. The loop is built to answer that; this page does not report the answer.
