Loop Engineering

Loop Engineering provides free, browser-based tools for designing safe, verifiable AI agent workflows. The toolkit includes a goal generator, verified templates, a budget calculator and a readiness doctor. It helps teams plan workflows with evidence, stop rules, budget limits, fallbacks and human approval gates. The outputs are copyable for Claude Code, Codex, Cursor, GitHub Actions and other agents. No sign-up is needed.

Use the goal generator to draft a goal for an agent workflow. Browse the verified templates for starting points, and adapt one to your use. Use the budget calculator to consider costs before running a workflow. The readiness doctor helps check whether a workflow is ready, including whether its controls and review points are made clear. The resulting text can be copied into the tools and agents you already use.

Loop Engineering is a workflow-design toolkit, not a model-generation platform or an autonomous execution service. It does not run an agent on your behalf. Instead, it helps you define what the workflow should do, what evidence it should produce, how much budget it may use, when it should stop, what fallback to use and where a person must approve the next step. These controls make the proposed work easier to review before it is handed to another agent.

The free browser-based tools are intended for developers and teams building or using AI agent workflows. Start with a goal, use a template if helpful, estimate a budget and check readiness. Then review and copy the output for the agent or automation environment of your choice. This makes Loop Engineering useful when you want explicit limits and human oversight in a workflow without asking the tool to execute the task itself.
