Multi-step agents keep poisoning themselves and I am tired

Summary

The author discusses a persistent challenge in multi-step AI agents where state contamination from previous steps leads to hallucinated outputs, and notes the need for cleaner context boundaries despite available tools like EnterPro Agent Builder.

Been poking at multi-step agents and the hard part isnt tool calling. it is keeping yesterday's junk out of the current step. Tiny test today. summarize one PDF, call a weather API, then summarize a different PDF. The last summary came back talking about London cloud cover like it was a supply chain metaphor. not kidding. the weather result was still hanging around, so the model politely stitched it into a logistics answer. Thats the part that scares me. the tool call worked. the prompts were fine-ish. the state was dirty. so now I am trying to be less casual about what each step gets to see. smaller inputs, cleaner outputs, fewer leftovers. I keep looking at builders like EnterPro Agent Builder for preview, publish, versions, and rollback. useful stuff. but clean step boundaries still feel like the open problem, not something I would claim any tool magically solved. are people isolating context between steps, or just praying the message array stays sane

The quiet reason your "autonomous agents" keep looping (a teardown of under-the-hood agent memory)

A technical teardown of how multi-agent frameworks like CrewAI and AutoGen actually route information under the hood, revealing that they are essentially automated prompt-chaining loops. The article explains why agents get stuck in infinite loops due to context window inflation and missing deterministic stop conditions, offering practical advice for builders to treat agents as functional programming functions instead of human collaborators.
