[FEATURE]:Proposal for Configuration-Based Three-Tier Language Internationalization in OpenCode #15800
Description
Feature hasn't been suggested before.
- I have verified this feature I'm about to request hasn't been suggested before.
Describe the enhancement you want to request
It is recommended that OpenCode introduce a three-tier language internationalization configuration in the settings file: the first tier for TUI interface language (e.g., ui.locale) to control static UI text; the second tier for LLM output language (e.g., llm.outputLanguage) to directly constrain the model’s natural language generation; and the third tier for tool call and output description differentiation (e.g., tool.callLanguage and tool.descriptionLanguage) to separately specify the language for tool execution syntax (such as enforcing English commands) and user-facing descriptions. All language preferences should be declared in the configuration file and automatically enforced by the system, eliminating the need for manual prompt engineering.

Strongly support the
llm.outputLanguagetier. My use case: forcing the model to consistently respond in Italian for all thinking and answering, without manual prompt engineering every session.github-actions commentedon Jul 3, 2026
