Use when a checked deck should become the file the app opens, or when the creator says /deck-pack, export the deck, or make the file.\nlicense: MIT\ncompatibility: Requires Node 22 and the kit's scripts (npm install in the kit folder); network access to vocabloot.com for the language registry, with an offline snapshot fallback.\n---\n\n# /deck-pack\n\n**Show your work.** This is step 5 of 6. Say so before the command, then post the result line (cards, stickers, size, SHA-256) and offer the file itself where the host can attach or download it, not only its path.\n\nCommands below run from the kit's root, the folder two levels above this file (`<kit>/skills/<this skill>/SKILL.md`); from anywhere else, prefix `scripts/` with that path. If a script answers that dependencies are not installed, run the `npm install` it prints.\n\n```bash\nnode scripts/pack.mjs <deck-folder>\n```\n\nThe packer runs every check first and refuses with the reasons if any fail; there is no override. On success it prints the card and sticker counts, the file's SHA-256 and the path (`<deck-folder>/<deckId>.vlbackup`).\n\nThe packer is the Vocabloot app's own codec compiled to JavaScript (`packer/`, built from the app's `shared/format` module); the file it writes is the same format the app exports. Tell the creator the file is ready and hand over to `/deck-publish` for how to open it.\n"
