Language Injection for Agent Prompts
Authoritative developer guide: docs/dev-guides/6-i18n-language-injection.md.
Prerequisites: Read
docs/dev-guides/6-i18n-language-injection.mdbefore changing Agent prompts, Agent routes, backend user-visible messages, or frontend i18n strings. If your work introduces new language injection patterns or conventions, update this file and related dev-guides accordingly.
Architecture
Frontend i18n.language → Accept-Language header → get_language_instruction()

Core Modules
| Module | Role |
|---|---|
agents/agent_language.py | build_language_instruction(lang, mode), generates prompt fragments; inject_language_instruction(), injects into system prompts; supports 20 languages; returns "" for English |
routes/agents.py → get_language_instruction() | Reads Accept-Language header, delegates to build_language_instruction |
routes/agents.py → _get_ui_lang() | Extracts primary language code from Accept-Language header |
src/app/utils.tsx → fetchWithIdentity() | Sets Accept-Language header on every API request from i18n.language |
src/app/utils.tsx → translateBackend() | Translates backend message_code / content_code using frontend i18n |
Code Examples
