Auto-promote new Webflow blog posts to LinkedIn and X

Whenever I publish a new article to my Webflow blog, automatically promote it on LinkedIn and X. Build this as an agent workflow.

Trigger: a Webflow webhook on the Collection Item Published event, scoped to my blog collection (I will pick the specific site and collection during setup). The webhook payload includes the published item's ID and the collection ID.

Step 1. Call Webflow Get Collection Item with the item ID from the webhook to read the full fieldData. I care about: title, summary or excerpt, body content, hero image URL, slug, canonical URL, tags or categories, and publish date.

Step 2. The agent's main job is platform-aware rewriting. It should:

- Read the body and pull a real opening hook out of it (a surprising claim, a question, a sharp observation). Do not just template the title.

- Draft a LinkedIn post: longer, first-person, conversational, 3 to 6 short paragraphs. Open with the hook. End with a clear call to action and the canonical article URL. No more than one or two hashtags, and only if they fit naturally.

- Draft an X post: punchy, must fit within 280 characters including the link. One or two hashtags pulled from the post's tags. Include the canonical URL.

- Treat LinkedIn's voice and X's voice as genuinely different. Do not produce two posts that say the same thing in different lengths.

Step 3. Publish both. Call LinkedIn Create Post with the drafted LinkedIn copy (attach the hero image if one is present on the Webflow item). Call X (Twitter) Create Tweet with the drafted X copy.

Step 4. Log the result. Return a short summary: which article ran, the LinkedIn post URL or ID, the X tweet URL or ID, and any errors. If either platform fails, the other should still publish; do not block one on the other.

Guardrails: never publish a duplicate if the same Collection Item Published event fires twice for the same item ID. Skip drafts or items in non-published states. If the hero image URL is missing or invalid, fall back to a text-only LinkedIn post.
