A production n8n workflow that pulls decaying posts from GSC (Google Search Console, 谷歌站长工具), drafts a refresh brief, has ChatGPT write the update, validates the new draft, and ships it to the CMS — all in one loop. The full node map, the three prompts, the four validation gates, and the three failure modes that have actually cost me a post.
Every Monday at 8:14 a.m. a Slack message lands with 4-9 underperforming posts. The n8n + Claude agent that writes it, the prompts that make Claude useful (and the ones that make it noisy), and the three things I changed after six weeks of running it for real.
A production-grade 4-agent content pipeline built in n8n. Each agent has a single job, a structured output, and a retry path. Includes the full workflow JSON you can paste into n8n, the prompts I use for each agent, the state schema that flows between them, and the failure modes that have actually cost me time.
