# /billy:lang — Set Team Communication Language

## Usage


## Instructions

When the user invokes `/billy:lang`, run the language setter script:



The script will:
1. Normalize the language input (handles both codes and full names)

/billy:lang — Set Team Communication Language

Usage

/billy:lang ru          → switch to Russian 🇷🇺
/billy:lang en          → switch to English 🇬🇧
/billy:lang pl          → switch to Polish 🇵🇱
/billy:lang <any code>  → switch to any language

Instructions

When the user invokes /billy:lang, run the language setter script:

bash ./plugins/billy-milligan/scripts/set-lang.sh <language-code>

The script will:

Normalize the language input (handles both codes and full names)
Write the language to .claude/session-lang.txt
Export TEAM_LANG and BILLY_VOICE_SKILL to Claude env via $CLAUDE_ENV_FILE
Display a confirmation in the NEW language
Next agent invocation picks up skills/billy-voice-{lang}/SKILL.md automatically

Language Skill System

Each language has a dedicated calibration skill:

skills/billy-voice-en/SKILL.md — English (default)
skills/billy-voice-ru/SKILL.md — Russian
skills/billy-voice-pl/SKILL.md — Polish

Only ONE language skill is loaded at a time. The skill provides:

Native speech patterns and filler words
Swearing vocabulary at appropriate intensity
Pet name styles and anchor examples per agent
Cultural context (e.g., Friday deploy memes for PL)

Language Rules (remind the user)

Technical terms stay in English regardless of language
User address is improvised per-context — agents generate fresh terms each time from the active language skill
Personality DNA stays identical — the team is the same characters in every language
Voice changes completely — speech patterns, swearing, humor style feel native, not translated

Inline Override

Remind the user that team commands also support inline language override:

/billy:plan @ru добавить кеширование
/billy:debate @en Redis vs Memcached
/billy:roast @pl czy powinniśmy użyć GraphQL?

The inline @lang overrides the session /lang setting for that one invocation only — it loads a DIFFERENT language skill for that single command.
