AI coding agents on production codebases: 4 setups tried, 3 failed, one workflow stuck
paulabartabajo_ · x · 2026-10-15
Developer paulabartabajo published a walkthrough of using AI coding agents on real production codebases (not vibe coding), based on actual client work. He tried 4 setups; 3 failed. The one that stuck: align with the agent on design first, then let it implement.
Topics covered:
- Vibe coding vs production software engineering
- One-shotting features with Claude Code
- Planning skills and vertical slicing
- Herder for running many agents in parallel
- HumanLayer IDE and task setup
- The Research → Design → Implement workflow
Directly useful for engineers trying to make coding agents work in real codebases.
