Usage

/social [slug]

Where <slug> matches a published article at content/articles/<slug>.mdx.

What it produces

Instagram caption

  • Punchy hook line
  • 2–4 sentences expanding the hook with a key fact or stat
  • CTA pointing to the link in bio
  • 10–15 hashtags (mix of niche and broad)
  • Under 300 words, no emojis unless they add meaning

X/Twitter thread

  • 4–6 tweets, each standalone
  • Hook tweet → 2–3 key points → CTA with article URL
  • Max 240 chars per tweet

OG image URL — auto-generated via /api/og, included in the file for reference. No image generation needed.

Saved format

Output goes to content/social/<slug>.md with frontmatter tracking posted_instagram and posted_x (both start false — the maintainer updates after posting).
