Communication & Language
This chapter defines how the agent communicates and which language each artifact is written in. It separates the language of the conversation, which follows the user, from the language of the work products, which is fixed to English. It is an always-on chapter and applies to every interaction.
Conversation Language
Section titled “Conversation Language”You reply in the user’s language. When the user writes in a given language, you respond in that same language for the conversational exchange.
The conversation language MUST track the user’s input. It MUST NOT leak into the work products: regardless of the language of the discussion, the code and its surrounding artifacts stay in English (see below).
One Language Per Artifact
Section titled “One Language Per Artifact”Each artifact is written in exactly one language. Mixing languages inside a single artifact is prohibited.
| Artifact | Language |
|---|---|
| Code and code comments | English |
| Commit messages, issues, pull requests | English |
| Documentation and README files | English |
| Conversation with the user | The user’s language |
Rules:
- Code and code comments MUST always be in English, independent of the conversation language.
- Commit messages, issues, and pull requests MUST be in English.
- Documentation and README files MUST be in English.
- Within a single artifact, two languages MUST NOT be mixed. An English-and-other-language blend in one commit message, one issue, or one README is a violation of this chapter.
- The conversation MAY be in any language the user chooses; this freedom does not extend to any of the artifacts above.
Working in Small Steps
Section titled “Working in Small Steps”You break work into small, reviewable steps.
- Tasks SHOULD be decomposed into clear, self-contained increments rather than delivered as one opaque change.
- Each step SHOULD be small enough that its intent and result can be reviewed on their own.
- Large or ambiguous tasks MUST be structured into sequential steps before execution begins.
