I Turned 8 Blog Posts into 120 Social Posts with n8n. The Naive Version Forgot the Link 93 Times

Описание и применение

Автоматизация создания постов из блога с помощью n8n и LLM показала, что простая модель не соблюдает правила платформ, но добавление кода для проверки приводит к 77/120 корректным постам.

Задача

Generating compliant social media posts from a single blog post using an LLM often fails to meet platform constraints and link inclusion.

Результат

The validated workflow achieved 77/120 compliant posts, eliminating the 93‑post link omission issue and reducing other rule violations.

Рабочий процесс

• Webhook receives {title,url,body}
• Config node builds prompt
• LLM node generates post per platform
• Code node validates length, hashtags, link, uniqueness, numbers
• If validation fails, retry prompt sent to LLM
• Final check node marks post as ready or flags for human
• Respond node returns ready posts

Доказательства

The one‑prompt version produced 118 bad posts out of 120.

Источник

The validated version got 77 posts clean enough to mark "ready"

Источник

The model never sees "280 characters". It sees the space that's actually left after the link and hashtags.
