Encode your manual QA steps as a SKILL.md verification skill so the loop starts closing itself

Claude by Anthropic·high signal

Anthropic's guidance is that the highest-leverage move in any agent loop is upgrading the verification step, not the orchestration. The concrete frontend recipe: start the dev server, open the edited page, interact with the change, screenshot before and after, assert zero new console errors, then run a Chrome DevTools performance trace against Core Web Vitals. The stated principle — the more quantitative the checks, the easier it is for Claude to self-verify — means every prose acceptance criterion you convert into a number removes a human turn from the loop.
