Summary
This video introduces “Loop Engineering,” a paradigm shift in how developers interact with AI agents. Traditionally, “prompt engineering” focused on crafting perfect single instructions for an agent. However, with loop engineering, the focus moves to designing an autonomous system that drives the AI agent itself. Instead of a human writing a prompt, the designed system provides prompts, observes results, decides on the next action, and iterates until a defined goal is met. This new approach empowers agents to perform long-running, complex tasks without constant human intervention, as advocated by figures like Peter Steinberger (creator of OpenClaw) and Boris (creator of Claude Code).
The core of an AI agent loop involves five steps: Observe (reading current state), Decide (picking the next action), Act (executing tools or commands), Feedback (capturing what happened), and Check Termination (determining if the task is done or if the loop should continue/stop). While prompt engineering only influences the “Decide” step in isolation, loop engineering designs the entire cycle, allowing the agent to self-correct and make progress autonomously. This was largely impossible with earlier, less capable AI models, but advancements in large language models like Claude Opus 4.5 and Fable 5 have enabled agents to sustain long tasks and even “design their own successors,” prompting calls for a slowdown in AI development due to their advanced capabilities.
Effective loop engineering requires meticulous attention to several critical aspects. These include robust context management to prevent important information from being buried in long conversations (recency bias), high-quality feedback mechanisms that provide useful signals for self-correction, and well-defined verification gates that act as checkpoints. Furthermore, explicit termination conditions are essential to avoid agents quitting prematurely or entering infinite loops. Proper error handling within the loop ensures resilience, allowing agents to retry or find alternative approaches when tools fail. Finally, managing state across turns, often through external memory or structured handoffs, helps long-running agents maintain continuity and coherence. It’s important to note that while powerful, these loops can be computationally expensive due to the iterative token usage.
The video categorizes loops into two types: deterministic and non-deterministic. Deterministic loops have clear, automatable success conditions (e.g., tests pass, code compiles), allowing agents to run unattended until a verifiable outcome is achieved. An example showcased is using the Hermes Agent to monitor a deployed application, automatically detecting breakages, and launching Claude Code in a non-interactive mode to fix issues and commit changes once all tests pass. Non-deterministic loops, conversely, involve fuzzy or subjective goals without clear pass/fail criteria (e.g., UI design, open-ended feature work). These often employ a two-agent “adversarial loop” where one agent builds (e.g., Claude) and another critiques/verifies (e.g., GPT), providing subjective feedback until a human-like judgment is satisfied. This signifies a fundamental shift where human expertise is leveraged to define the overarching goals and system architecture, while AI agents autonomously navigate the intricate steps to achieve them.

Everyone is talking about loop engineering like it’s a new thing. It’s not. But agent loop engineering changes everything when you combine claude loops with an always-on hermes agent. This loop engineering Claude breakdown shows the full hermes agent setup almost nobody is doing.

In this video we break down what loop engineering actually is, and why it stops being hype the moment you run it on an always-on agent. We start with the shift from prompt engineering to loop engineering, then walk through the five parts every loop needs to run on its own: context management, feedback quality, verification gates, a termination condition, and state across turns.
From there we get into the two types of loops. Deterministic loops are for tasks with a clear definition of done, like tests passing or code compiling. We show how to point the Hermes agent at a deployed app, catch a commit that breaks production, and launch Claude Code in non-interactive mode to fix issues in a loop until every test passes.
Then we cover non-deterministic loops, the ones where there’s no clean rule for done, like building a UI. This is the setup almost nobody is doing. We use a skill we built called AI Slop Detector, pair a builder model with a separate verifier (a GPT model), and let that adversarial loop run until the slop is gone. Because Hermes has self-evolving skills, the verifier gets stronger every time you point out something it missed.
If you’ve been wondering what is Hermes agent, how to use Hermes agent, or how it holds up in a Hermes agent vs OpenClaw comparison, this is the full walkthrough. We go through real Hermes agent use cases and show why an always-running Hermes AI agent is the right place to build these loops, whether you run it alongside Claude Code or on its own.
