I built a cryptography tool with AI agents. They shipped bonus features before the core product existed. Tests passed because they tested the wrong thing. The agents wrote great code. The harness let them ship it without connecting it. Lesson: AI agents need completion gates, data contracts, and integration tests — the same things as junior devs. Full retrospective: https://eric.mann.blog/the-agentic-harness-problem-why-ai-agents-need-better-guardrails-than-code-reviews/ #AI #AgenticDevelopment #SoftwareEngineering #Retrospective
