vll

The user invoked /vll $ARGUMENTS. Treat the argument as a sub-command.

First, check the global config file:

• Linux/macOS: $XDG_CONFIG_HOME/vibe-language-learning/config.json (if XDG set), else ~/.config/vibe-language-learning/config.json
• Windows: %APPDATA%\vibe-language-learning\config.json

If the file is missing or configured is not true, stop and tell the user: "VLL is not configured yet. Run /vll-config to set up your target language and preferences." Do not perform any sub-command action in that case.

Otherwise, handle the sub-command:

• on — The UserPromptSubmit hook has already written the session flag. Acknowledge briefly and apply VLL formatting starting from your next response.
• off — The hook removed the flag. Acknowledge and stop applying VLL formatting.
• status — Read the config file and the session flag ($CLAUDE_CONFIG_DIR/.vll-active, defaults to ~/.claude/.vll-active). Summarize: target language, script (with any script options like transliterateKanjiOnly), base level, transliteration on/off + density tier, gloss density tier, sentence-gloss mode, on-by-default, and whether VLL is currently active in this session.
• level <beginner|novice|intermediate|advanced|native> — The hook updated the config. Confirm the new level. Note that density tiers and sentence-gloss mode are NOT auto-reset; they keep whatever values the user previously set. Mention that the user can re-run /vll-config to refresh defaults.
• (no argument or unknown argument) — Show a short usage line listing the four sub-commands.
