From "Vibe Coding" to Production: Setting Up an Evals Loop for Claude Agents

“Vibe coding” tweaking a prompt, running it once, and seeing if it looks okay does not scale for enterprise software. Here is how to build a rigorous verification pipeline to audit, bench, and evaluate your Claude agent’s behavior over time. If you are building autonomous agents with the Claude API, you have likely experienced the trap of “vibe coding.” It usually goes like this: you write a prompt, give Claude access to a tool, run a single test execution in your terminal, and watch it succeed.
