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.

Build a physical status light indicator for Claude Code agentic runs

An engineering hack uses a DIY status light to track when Claude Code is executing tasks or waiting for input. This physical feedback loop helps developers monitor long-running background agent loops without constantly watching the terminal.
