/lang --first=en --second=vi --mode=full

How it works

Set the session language for all AI-generated content.

Single language (only one specified, or both the same):

• /lang --first=vi — All content in Vietnamese
• /lang --second=en — All content in English
• /lang --first=en --second=en — All content in English

Bilingual mode (two different languages):

• /lang --first=en --second=vi — English with Vietnamese terms in parentheses (default: term mode)
• /lang --first=en --second=vi --mode=term — Technical terms translated in parentheses
• /lang --first=en --second=vi --mode=full — Full bilingual with alternating paragraphs

Supported languages: en, vi, fr, zh, de, ja, es, pt, ko, th

How it works:

• At least one of --first or --second must be provided
• If both are the same language, it's treated as single-language mode
• --mode is only used in bilingual mode (ignored for single language)
• Language is auto-detected from your first prompt when creating a plan
• Use /lang to change it mid-session if needed
• Affects: PoK content, chat responses, command responses (/explain, /summary, etc.)
• Does NOT retroactively change already-generated content
