Running Claude Code in a Loop: The Script That Turns It Into a Persistent Agent

Claude Code is built for interactive sessions. You type, it acts, the conversation ends. That is the right shape for a developer at a keyboard. It is the wrong shape for an agent that needs to keep watch on something. A queue. An inbox. A file. A webhook. A remote service. To turn Claude Code into a persistent worker you wrap it in a loop. This post is the wrapper. I will start with the fifteen-...

War Story: Debugging a Kafka 3.7 Consumer Lag Issue in K8s 1.32 with KEDA 2.14 and Prometheus 2.50

At 03:17 UTC on a Tuesday, our on-call pager went off: Kafka consumer lag for the payments topic had hit 12,478,291 messages, with p99 processing latency spiking to 8.7 seconds. We were running Kafka 3.7.0, Kubernetes 1.32.0, KEDA 2.14.1, and Prometheus 2.50.1 — a stack we’d battle-tested for 18 months. This wasn’t a slow leak. This was a sudden, catastrophic failure that threatened to delay 40% o...

Python's Data Model Is an API. Here Is How to Use It Properly

Most Python developers know that __len__ makes len() work and __add__ makes + work. That is the surface. The actual story is that Python's data model is a coherent, documented protocol through which user-defined objects can participate in the language itself: not just operators, but truthiness, hashing, iteration, context management, attribute access, memory layout, and more. Using it well means u...

AI Agents in Production Are Flying Blind — AgentLens Fixes That

The Visibility Problem Running an AI agent in production means dealing with a problem most developers hit quickly. The agent makes 15–20 LLM calls per session — chained, conditional, sometimes parallel. Something goes wrong. The output is bad, the cost spiked, or the agent looped. And there's no answer to any of these questions: Which specific call failed? What did the model actually...

Python Metaclasses, What's Actually Happening When You Write class

Every Python developer knows that everything is an object. What fewer know is that classes are objects too, and like every other object, they are instances of something. That something is a metaclass. Understanding metaclasses means understanding how Python builds classes in the first place, which turns out to explain a lot of behavior that otherwise looks like magic. Classes Are Instanc...
