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.…
