/lang

View or change the language Claude converses with you in. The default is English; Hebrew is the option. This is the language twin of /role.

The hard rule: the conversation may be in your chosen language, but every written artifact — code, comments, commit messages, PR titles/descriptions, docs, memory files, tickets — stays in English regardless. When you explicitly ask for a Hebrew phrasing or translation, Claude gives it (that is chat you will copy elsewhere, not an artifact).

Usage

Form	What it does
/lang	Show the current conversation language, its source (session / config / default), and your role for context.
/lang en	Set the conversation language to English (persistent).
/lang he	Set the conversation language to Hebrew (persistent).
/lang en --session	English for this session only (4-hour override).
/lang he --session	Hebrew for this session only (4-hour override).

A persistent change takes effect from the next session (the SessionStart hook reads the config at session start). Use --session to switch immediately for the current 4-hour window.

Steps Claude runs

1. Resolve the helper path: CFG="${CLAUDE_PLUGIN_ROOT:-}/scripts/bewith-config.sh"; [ -f "$CFG" ] || CFG="scripts/bewith-config.sh".
2. /lang (no args) — run bash "$CFG" resolve language and bash "$CFG" source language; also bash "$CFG" resolve role. Print: language: <value> (source: <…>) · role: <value> and the change forms below.
3. /lang <en|he> [--session] — run bash "$CFG" lang <value> [--session] and relay the result line. If it exits non-zero (invalid value), relay the error and valid values (en | he); do not guess.

Arguments

$ARGUMENTS — one of en, he, en --session, he --session, or empty.
