Insights on AI agent optimization, prompt engineering, and shipping reliable agents.https://www.mutagent.io/https://www.mutagent.io/blog/three-ai-debts-artifact-mindset/https://www.mutagent.io/blog/three-ai-debts-artifact-mindset/A recent VentureBeat piece named the right symptoms in enterprise AI: prompt debt, retrieval debt, evaluation debt. The cause sits one layer down, in how teams still treat agents as artifacts to ship instead of systems to evolve.Thu, 28 May 2026 00:00:00 GMTDr.-Ing.
