This document summarizes a presentation about quality check tools for software development. It introduces several tools for checking code quality such as Bundler-Audit, RubyCritic, and Reek. It emphasizes that these tools should be used as early as possible, such as during continuous integration or with git hooks. Maintaining code quality helps control technical debt. In the end, the presentation argues that quality is a habit developed through repeated practice.
