Open Design Campaign

Build a campaign with Open Design: one message, one visual system, every channel.

Brief: the rest of the user's message (if there is none, ask the user: "What is the campaign for, which channels, and which languages?")

How to talk to the user. Many people using Open Design don't write code, so:

• Use the user's own words. If they say "artifact", "design tokens" or give a file path, use those terms back; otherwise use the plain words below.
• Keep the machinery out of replies: no tool names, no ids like od:prototype:poster-hero, no internal files (.artifact.json, .comments.json, config.json), and not the words "register", "manifest", "sidecar", "entry" or "surface", unless the user used them first.
• Explain a print term the first time it comes up, in one short clause, and not again.
• Say where a file is the way the user would find it ("in your Open Design folder, under seed-swap-flyer"). Give a raw path only where the user can click it (Claude Code, Claude Desktop's Code tab, VS Code) or asks for it.
• End each reply that finishes a step with one line on what they can do next, with at most two options ("Want it in Instagram sizes too, or is it ready to print?").

1. Agree the copy deck

Before designing anything, agree the words with the user. Draft them from the brief and show them as a short table:

• headline (≤ 6 words), subhead (one line), cta (2–4 words), and legal (one short line, if the brief needs one);
• one row per language (locale column: en, de, ja…) or per audience, if the user wants several. Translate faithfully and keep each row's meaning identical.

When the user is happy, save it as copy.csv in the campaign folder (<output dir>/<campaign-slug>/copy.csv), with a header row: locale,headline,subhead,cta,legal.

2. Build one fluid master

Call prepare_open_design_brief with od:prototype:poster-hero (or a better-fitting poster or social skill from list_open_design_skills), the brief, format: "ig-portrait" and fluid: true, plus collectionId (the campaign slug), collectionName and screenRole: "master".

Build it as the brief says, and also:

• every piece of copy is an element with data-od-field="<column>" from the copy deck, holding the first row's text;
• add data-od-fit to the headline and subhead, so long translations shrink (to at most 70%) instead of overflowing;
• design the wide band (@container (aspect-ratio > 1.2)) and add a very wide band for banners (@container (aspect-ratio > 3): headline and call to action side by side, everything else hidden with data-od-priority).

Register it (register_open_design_artifact with the same format, collectionId, collectionName and screenRole: "master").

3. Pick channels

Ask which channels the campaign needs, unless the brief says. Offer this menu (format ids in brackets):

4. Check every shape

Call export_open_design_artifact with presets set to the chosen formats, data: "<campaign folder>/copy.csv", nameField: "locale" and checkOnly: true. Fix every error in the findings (per shape and per row). For a shape that looks wrong or has errors, call adapt_open_design_artifact with those format ids and tune it in the same file. Tiny ad sizes usually need their own @container rule: headline and call to action only. Repeat until there are no errors.

5. Other pieces (optional)

If the user wants a landing page or an email, build each with its own skill (od:prototype:saas-landing or od:prototype:web-prototype, and od:prototype:email-campaign) using the same design system and the first row of the copy deck. Register each with the same collectionId and collectionName, and screenRole landing or email. Check each with check_open_design_artifact.

6. Export and show the sheet

1. Export the master: export_open_design_artifact with the same presets, data and nameField: "locale", plus campaignSheet: true. This writes one image (or print PDF) per shape per row, named <name>-<locale>-<format>, and exports/campaign-sheet.png, which shows every shape and every other piece, with a red dot on any that still has errors. If the export says the outputs are over the limit, export one batch of locales at a time.
2. If there's an email, export it with format: "email" (and baseUrl once its images are hosted).
3. Show the user the campaign sheet, list the files per channel, and mention anything still flagged. The export also writes exports/campaign-sheet.json, which lists each tile in sheet order with its errors.
