| description | Generate 01MVP-style black-and-white article illustrations and visual concepts. Use when the user asks for 01MVP handbook/blog/docs/marketing images, Chinese article illustrations, shot lists, visual metaphors, compressed social-media-ready image assets, assets.01mvp.com uploads, or imagegen prompts that should feel concise, direct, high-impact, and visually consistent with the 01MVP operator style. |
01MVP Art
Generate 01MVP article illustrations in one unified style: white background, chunky black 01 operator, thick marker lines, one red-orange accent, and a direct physical metaphor. Use assets/examples/00-character-exploration.png as the style anchor.

Workflow
- Pick one cognitive anchor from the article: validation, payment, launch, cut scope, feedback, or automation timing.
- Convert it into one physical action: cut, push, launch, crank, charge, weigh, block, collect, or ship.
- Draw the 01MVP operator doing that action. The character must drive the meaning, not decorate the page.
- Keep the image obvious at a glance. If the idea needs many arrows or many labels, reduce the metaphor.
- Use imagegen directly for short Chinese text. Keep text to 1 title plus 2-4 labels, each 2-6 Chinese characters.
- Save only compressed review/production assets by default:
- Web/docs default:
1600x900 WebP, quality around 82.
- Social fallback:
1600x900 JPG, quality around 86 when a platform does not accept WebP.
- Upload approved/reusable compressed images to R2 by default. Prefer
wrangler r2 object put --remote against 01mvp-public-assets; use environment variables only for bucket/public URL overrides. Never print or store access keys.
Quality Gate
- Generate one image per article concept. Do not use one crowded contact sheet as the final article image.
- Review a contact sheet before upload when generating more than 3 images.
- Reject images with wrong Chinese text, unrelated subjects, weak metaphors, thin lines, cute mascots, or decorative clutter.
- Use dated filenames such as
<slug>-YYYYMMDD.webp for public R2 URLs, so a pre-upload 404 cannot poison the final URL through CDN cache.
- Verify every final public URL with
curl -I; it must return 200 and content-type: image/webp.
- Insert only R2 URLs into 01MVP docs. Do not commit generated article images into the web repo unless explicitly requested.
Output Rules
- Do not ship raw imagegen PNGs as the final article asset.
- Do not use local text overlays as the default path.
- Keep source PNGs only as temporary working files unless the user asks to preserve them.
- For 01MVP web docs, do not add generated article images to the repo unless the user explicitly asks for local files.
- For approved/reusable images, use
https://assets.01mvp.com/images/docs/01mvp-art/<slug>.webp in MDX and other docs.
R2 Upload
Use wrangler auth by default. These non-secret environment variables may override the default target:
MJ_01MVP_ART_R2_BUCKETMJ_01MVP_ART_R2_PUBLIC_URLPUBLIC_UPLOAD_BUCKETPUBLIC_UPLOAD_PUBLIC_URL
Do not print, persist, or document API tokens/access keys.
Default upload path uses wrangler ... --remote, so explicit R2 keys are not required when Cloudflare auth is already available in the shell:
scripts/upload-r2-asset.sh images/docs/01mvp-art/<slug>.webp /tmp/<slug>.webp
If wrangler is not authenticated and no safe upload path is available, keep the compressed file in a temporary working directory and report that upload was skipped. Do not fall back to committing image files into the web repo.
