Until today the distribution hub built every social draft from two fields: a post's title and its one-sentence description. So X, LinkedIn, Reddit and a video script all said the same thing, New write-up: <title>, one sentence and a link. That is an announcement. A reader scrolling LinkedIn or a subreddit needs the finding itself, and the post body already has it.
The new content engine (platform/distribution/hub/content.mjs) reads the body, scores each sentence and lays the best ones out natively for each platform. Sentences with numbers and sentences from the opening paragraph rank up; file paths and repository housekeeping rank down. Sentences that say what a result does not show are kept apart as limits. From one post it makes a numbered thread sized for X (280 characters), Bluesky (300), Threads and Mastodon (500), a LinkedIn post with the findings as bullets, a Reddit body with a TL;DR, findings, limits and an affiliation disclosure, a Hacker News first comment, carousel slides and a spoken video script.
The rule that makes it safe to automate: it extracts and never writes. Every sentence a reader sees is quoted word for word from the post, clipped on a word only when a limit forces it. The only words it adds are fixed labels ("What the data showed", "Limits", "3/6") and the disclosure. So a draft can be no more wrong than the post it came from. It calls no model, costs nothing to run, and gives the same text on every run.
Run against all 1,470 posts in docs/posts/, 1,456 yield a kit, with 3.35 findings and 1.35 stated limits each on average. No extracted sentence is missing from its post, and no piece exceeds its platform's limit. The test suite repeats that check on every post, so a change to the scorer cannot quietly start paraphrasing. Building those checks found two bugs first: a code span such as fix-<n> lost its <n> to the HTML stripper, and a post with an empty description got no findings at all.
What did not change: the channels that can post unattended (Threads, Facebook, Instagram, email, and the Bluesky and Mastodon bots) post exactly the text they did before. The richer shapes go to the drafts the owner posts by hand, and a community's own rules still decide whether something goes up at all. Most subreddits and Hacker News forbid automated posting, so nothing posts there automatically. No platform is live yet; each one waits for the owner to switch it on.
