I tested my autonomous content pipeline six times and found nine bugs. The model caused exactly zero of them. Every single failure was in the harness -- the environment around the model. This post walks through all nine, what caused them, and the one fix that retired most of them at once. What I built I wired up an autonomous content pipeline with Claude Code. Three independent AI sessions chain together: Observer -- scans the landscape (trending topics, competitor articles, performance data) Strategist -- picks the topic, decides the angle, writes an outline Marketer -- writes the full article, runs quality checks, schedules publication Each phase is a separate Claude session. The Observer's output becomes the Strategist's input. The Strategist's output becomes the Marketer's input. No human in the loop unless something fails a quality check. I drew this on a napkin and felt like a genius. On paper it was perfect.…
