A practical checklist argues that merging to `main` is a commitment, not a formality. Before approval, ensure unit tests exist and assert real behavior, not just execution. UI must align with the design system, and code should be readable, following team patterns. Mobile compatibility and proper folder structure are non-negotiable, as is using Storybook for component states.

The guide emphasizes performance considerations, like avoiding unnecessary re-renders, and enforcing clean tooling with ESLint and Prettier. The core question is whether you’d be comfortable owning this code in six months. This checklist protects the codebase from future pain, shifting reviews from gatekeeping to collaborative maintenance.

Adopting such a structured review process helps teams scale. It prevents technical debt from silent UI inconsistencies or untestable logic. While tools automate linting and formatting, human judgment on readability and intent remains key. The final test is ownership: if the code isn’t maintainable, it shouldn’t merge.
