CLI image generation for newsletter publishers

Know where the CLI stops and the publishing workflow begins

The CLI is an interface to Studio's cloud generation service, not a local renderer or newsletter platform. OfflineCreator says web, MCP, CLI, and API generations use the same account credit balance and published per-model costs, and that CLI inputs go to the disclosed cloud provider for the selected model. Do not put confidential draft copy, subscriber data, or unapproved source material into a generation prompt.

After generation, the newsletter system still owns responsive placement, compression, alternative text, links, tracking, audience segmentation, test sends, and final approval. If the project requires on-device generation, the current product page points to LocalForge as the separate offline option; that is a processing-boundary choice, not proof that the two products have identical commands or outputs.

Choose generation, cropping, or live layout by the actual problem

The issue needs a new visual direction

Generate one 16:9 proofAsk for subject placement and negative space, then evaluate one genuine result inside the newsletter shell.

The approved hero only needs another placement

Crop before regeneratingUse the existing source when a square or vertical crop preserves meaning, subject integrity, and copy-safe space.

Important words must be readable and adaptable

Use live HTML textDo not ask the image model to carry the only headline, offer, date, or call to action.

Mobile loses the focal subject

Create an art-directed derivativeAuthorize a 9:16 or 1:1 composition and review it as a separate asset rather than assuming cross-generation consistency.

Use the CLI to make artwork, not a flattened newsletter

Treat the generated image as a visual layer for the issue, not as the issue itself. Start with one 16:9 hero concept that leaves calm space for the subject line or deck, but add that copy as live text in the newsletter template. The current OfflineCreator CLI accepts a model, prompt, `--aspect 16:9`, and an optional `--wait`; its published implementation also accepts `--aspectRatio` and maps only 16:9, 9:16, or 1:1 into the generation request.

A practical first proof is `npx @offlinecreator/mcp@0.1.2 generate --model "$MODEL" --prompt "Wide editorial photograph, subject on the right third, quiet left half, restrained palette, no lettering, no logo" --aspect 16:9 --wait`. Under the configured Studio account, run the package's `models` and `balance` commands first, then confirm the published per-model credit cost on the product surface before authorizing generation. The prompt asks for copy-safe composition; it does not guarantee accurate brand details, an accessible crop, or publication-ready output.

Move from one issue brief to a reviewed asset set

Issue brief

One visual ideaWrite the article theme, intended emotion, subject-rights status, copy-safe side, prohibited elements, and human approver before spending credits.

Hero proof

16:9Generate one wide candidate without embedded headline copy, then place it behind the real newsletter heading at the actual desktop and mobile widths.

Social derivative

1:1 or 9:16Create a separately reviewed composition only when a crop of the approved hero cannot preserve the focal subject and required negative space.

Delivery record

Prompt, model, ratio, reviewKeep the exact command inputs, output identifier, rights notes, alt decision, and approval result with the issue's production files.

Make the accessibility decision in the newsletter context

First decide whether the hero contributes information. W3C guidance calls for a short alternative that conveys the essential information of an informative image. If the visual is decorative or repeats nearby live text, use an empty `alt` value so assistive technology can skip it. If the image is the only content of a link, the alternative needs to communicate the link's function rather than merely name the scene.

Keep the headline, offer, date, byline, and call to action as live text whenever the technology can create the same presentation. WCAG 2.2 Success Criterion 1.4.5 prefers text over pictures of text, except when the image can be customized or the exact presentation is essential. This lets readers resize or restyle important words and prevents a generated pseudo-headline from becoming the only copy of the message.

Test the assembled issue, not just the downloaded image. Check meaningful alternative text, empty alternatives for decorative derivatives, link purpose, reading order, crop behavior, and contrast between live copy and the image at narrow and wide widths. A generated image can support an accessible newsletter, but generation alone does not establish conformance.

Continue from the next unresolved production decision

Use the creator-use-case directory when the newsletter is one part of a broader image and video plan. Open the podcast pack when one approved episode idea must become cover, clip, carousel, and thumbnail concepts. Use the founder playbook when the issue supports a product launch and needs coordinated site and announcement visuals. These routes keep this page focused on the newsletter-specific handoff: wide artwork, live editorial text, a contextual alt decision, and reviewed derivatives.

Evidence boundary for newsletter publishing

This draft does not publish practitioner or community claims about the exact newsletter workflow because the available recent-source material did not establish them. Community coverage remains marked insufficient, so absence from this page must not be read as evidence that publishers are uninterested. Generic CLI discussion and unrelated repository activity cannot support adoption or outcome claims.

Accordingly, this draft relies on current first-party product interfaces for CLI and ratio facts and on W3C accessibility guidance for text alternatives and images of text. It makes no claim about deliverability, click-through rate, conversion, visual quality, model consistency, client compatibility, or production speed. Those remain editorial and hands-on verification gaps.
