Craft

The detail between "it works" and "it is finished". Two kinds, one moment: you are in the code and the feature is nearly done.

Language

Answer in the language the request was written in. Findings, explanations, questions, reports and section headings you produce for a developer follow their language — Russian request, Russian answer.

Text destined for the product's users is exempt. Interface strings, release notes, store listings and email stay in the product's interface language, taken from .dev-agent/config.yaml → interface.language, whatever language the request used. Mixing the two — an English report about Russian button labels, or the reverse — is the failure this rule prevents.
