Gauntlet Loops show how to push Claude Code past self-grading and into long runs

This article explains Gauntlet Loops, the prompting method behind the “Claude of Duty” build.
The core idea is to give the agent a standard it cannot talk its way around, split the work, and keep comparing output against a much higher bar instead of letting the builder grade itself.
The author says the original project used Claude Code with a single prompt, ran for many hours, spawned a large fleet of subagents, and produced roughly 55,000 lines of code plus every texture, mesh, animation, and sound from scratch.
The method is presented as broadly useful for:
- code
- websites
- product design
- marketing campaigns
- writing
- research
