The approach, called harness engineering, combines feedforward rules (a CLAUDE.md file and .claude/rules/) with a feedback loop: a Stop hook that runs RuboCop against any Ruby files the agent touches, auto-corrects what it can, gives the agent one chance to fix remaining violations, and surfaces what it can't. The post also covers creating a .rubocop_strict.yml to prevent silencing critical cops (ThreadSafety, Lint/Debugger) and writing a custom RuboCop cop to deterministically block inline disable directives for those cops. ## Full article daily.dev links to this article rather than hosting it.
