The Shift to Harness-Level Agent Loops in Software Engineering
The development workflow is shifting from manual prompting to outer harness loops that orchestrate agent sessions. While highly effective for mechanical translation and porting code, these autonomous loops often generate overly defensive, complex, and unmaintainable code for long-term production systems.
Why it matters. Understanding where agentic loops excel—and where they generate technical debt—helps developers choose the right automation boundaries.
