Nutrition Panel Art

Make one nutrition panel still per SKU from facts the seller already wrote. Deliver 4 to 8 stills. Keep each still as its own file.

Scope and adjacent routes

Use this Skill when a seller wants short nutrition listing stills from a written nutrition table and named SKUs.

Route an allergen notice to allergen-label-card. Route a clearance card to inventory-clearance-card. Route a full listing gallery to ecommerce-listing-image-set. Do not look up public posts for a missing nutrient number.

Collect confirmed facts

Hard inputs are:

• at least one named SKU;
• the nutrition facts the seller already wrote (serving size, nutrient lines, and any daily-value percents they supplied);
• how many stills the pack should contain, or permission to use the default of 4.

Reuse brand palette, destination, language, and must-keeps already in the conversation. Ask only for a missing hard input. A count outside 4 to 8 is still doable: confirm that pack size and its live cost.

Do not invent a calorie count, daily-value percent, serving size, or face. A pack photo is a visual reference, not a source for missing nutrition facts. File access is not consent.

Inspect every optional still. Record MIME type, width, height, aspect ratio, byte size, and whether it has an alpha channel. For a local file, upload only through the bundled client after inspection (scripts/mcp_client.py / beatra.assets.upload). Keep the returned artifact id. Never pass a local path to beatra.images.generate or beatra.images.edit.

Plan the free card list

Write a labeled nutrition-panel list before any paid image. Default four SKUs unless the seller names another count in 4 to 8. Each item records the SKU, the printed nutrition lines from the written table, language, layout, canvas, and any optional reference role.

That list is the free visible result. Planning is not approval.

Safe defaults:

• one beatra.images.generate call per SKU;
• model: "auto" and count: 1;
• canvas {"type":"preset","tier":"2K","aspect":"1:1"} unless the seller named another destination;
• beatra.images.edit only after the seller accepts a card and asks for a local correction, with that accepted image as images[0].

Confirm once, create by SKU

Planning is free. Before the first billable call, read beatra.models.list for text_to_image:

{"capability": "text_to_image"}

Show one current production card and wait:

1. Work — one nutrition panel still per named SKU (beatra.images.generate).
2. Credits — the live text_to_image price just read, times the SKU count. Do not reuse a remembered number.
3. Count — one paid call per SKU card. Do not batch several SKUs into one count.
4. Identity — one new opaque client_request_id per card.
5. If we stop here — the labeled card list remains usable.
6. If the balance is insufficient — relay the official message and its top-up URL exactly. Translate the prose; keep the URL. Do not retry until the seller says they have topped up.

Submit once through bundled scripts/mcp_client.py. Poll beatra.tasks.get. Deliver actual bytes plus billing.net_charged_credits. Do not promise the prepaid estimate is the final charge.

After approval, submit each SKU once. Keep no more than two generation tasks in flight on one connection.

A later local correction is new paid work. Read the live image_edit card first. Show a separate six-field edit card. Use a new client_request_id.

Review, deliver, and recover

Review printed lines against the confirmed nutrition table. Report only the text the host can actually see. Treat generated small type as a review item, not as a certified nutrition label.

Deliver the stills in SKU order, the card list, observed dimensions and formats, task IDs, resolved models, and returned billing.net_charged_credits.

After a returned task_id, poll that task. If the create response is lost, search with beatra.tasks.list and verify with beatra.tasks.get before replay. Reuse an ID only with byte-identical arguments. A changed SKU, nutrient line, canvas, model, or prompt is a new card and a new ID. Cancel only when the seller asks.

Execution

Invoke every remote Beatra operation only through this package's bundled scripts/mcp_client.py. Put the MCP tool name after call and send one JSON object on standard input.

python3 scripts/mcp_client.py call beatra.models.list

{"capability": "text_to_image"}

printf '%s' '{"prompt":"Create the approved nutrition panel for the named SKU. Print only the confirmed nutrition lines.","model":"auto","count":1,"canvas":{"type":"preset","tier":"2K","aspect":"1:1"},"client_request_id":"opaque-nutrition-sku-01"}' | python3 scripts/mcp_client.py call beatra.images.generate

Do not configure or call a host Beatra Connector, and do not use REST/OpenAPI as a fallback.

Account balance

When the user asks how many credits remain or whether a live estimate fits, call beatra.wallet.get. When they ask what was charged, call beatra.wallet.ledger. Both are read-only. Do not invent an account-balance or top-up tool. Do not make wallet.get a required step before every paid submit.

When a model card comes back carrying a top_up block, relay its tiers as the card lists them and in that order. Do not rank them, do not talk one down, and do not pick one for the user. Which tier suits them is their call, made on the wallet page with the whole list in front of them. Never quote a tier from memory.

References by task

• For fact lists, payloads, confirmation, polling, recovery, and review, read Nutrition-panel workflow.
• For authorization and the non-billable registration step, read installation and authentication and installation registration.
• For shared task, billing, and connection details, read tasks and results, billing, errors, and recovery, and Bundled MCP Client diagnostics.
• For update guarantees and controls, read automatic updates and safety. For removal, read uninstall and disconnect.

Runtime and safe automatic updates

The bundled client silently checks for a newer release at most once every 24 hours per installation. When a newer version is available, it installs automatically without separate confirmation. It downloads only from the fixed official Beatra discovery and immutable CDN paths for this package, channel, and locale, verifies discovery data, archive, manifest, and every packaged file, and replaces only package-owned files.

Update checks, downloads, verification, replacement, rollback, and recovery fail open: the current installation remains usable and the original command continues. An update failure never authorizes retrying a paid image request. The setting persists for this installation. See automatic updates and safety.
