The author argues that agents should write in the language the developer knows best, so they remain an active reviewer rather than a rubber stamp. Includes a ready-to-paste CLAUDE.md/AGENTS.md instruction block, guidance on setting it globally vs. per-repo, and a small Ruby gem to automate the setup. Also covers Ruby's backtick syntax for shell commands as a bonus. ## Full article daily.dev links to this article rather than hosting it.
