Manga-drawing skill · manga-forge

Ask for “a five-page manga” in one line, and AI hands back finished color pages with speech bubbles and page numbers

Ask Claude Code for a manga, and Claude writes the story and storyboard while Codex draws each page and hands it back as an image. It all runs within the usage of a paid Claude plan and a ChatGPT Plus or higher subscription. If a page looks off, ask for a few more fixes. We gathered pages from people who made their own and posted them.

In panels and speech bubbles, it tells how pasting a repo link and adding one line turns into a manga — A demo from the creator. さ🥺 (@_sagyoai), who built manga-forge, drew this sample page 1 with the skill and posted it on X.

On October 15, 2026, さ🥺 (@_sagyoai), an independent developer in Japan, posted on X. They had thought about charging ¥4,000 to teach people how to use a manga skill they built, then dropped the idea because it was a hassle, so the skill was free. By October 26 the post had 119,724 views and 3,177 bookmarks.

Over the next three days, people started posting pages they had drawn with it. On the 17th an AI illustration creator posted a five-page explainer manga, and on the 18th another user posted a four-page gag manga. On the 19th, fortune-teller VTuber ケイロカミオカ posted three pages generated in a single run and wrote, "凄い、マンガになっていて驚き。(Amazing. I'm surprised it actually came out as a manga.)"

manga-forge is a skill you add to Claude Code. Claude first writes the story and storyboard (a file listing panel positions, dialogue, and where each character stands), then Codex draws one page at a time from it. The skill gathers and checks the finished pages, then hands them over as page images like page1.png and page2.png. The skill is free (MIT license), and the creator wrote that modifying, redistributing, selling, and monetizing it are all fine.

A five-page explainer manga, with the real commands drawn into the panels, shows how its creator built their own AI pet character

ぐふとくく built their own pet character for Codex, 「しずく」, then used manga-forge to turn how they made it into a manga and posted it as an X thread on October 17. One page in the first post, four in the second, five pages in all. The manga is about Codex pets, and Codex image generation drew it.

It is titled 「Codex Petを自分のキャラにする方法」 (How to turn a Codex pet into your own character), and every page carries a page number like 2/5 or 3/5. A blond character in glasses explains three steps. STEP1 is 「専用スキルを入れる」 (install the dedicated skill), STEP2 is 「キャラの絵を渡して頼む」 (hand over your character art and ask), and STEP3 is 「あとは待つだけ」 (now just wait). The actual commands you type, $skill-installer hatch-pet and $hatch-pet この画像のキャラでペットを作って (make a pet from the character in this image), are drawn right into the pages.

In the third post of the thread, ぐふとくく said they made the manga with manga-forge, the skill さ🥺 released.

A few rounds of “fix this part,” and a four-page gag manga was done

On October 18, リナモ posted a four-page gag manga made with the skill, 「脱ぎたい忍者と作戦会議」 (Strategy meeting with a ninja who wants to strip), and wrote: "このスキルで漫画を作ってみた！本当にプロンプトを打って、直してほしいところを何度か指示するだけ。すごい。(I tried making a manga with this skill! I really just typed a prompt and told it a few times what to fix. Amazing.)"

The story parodies the game Wizardry, and the pages are numbered 1/4 through 4/4. On page 1, the party levels up in the inn's stables and heads for the entrance to the maze.

A repo link and one line, “set this up so I can use it,” produced a four-page sample manga about that very process

On October 16, the creator さ🥺 laid out how to use the skill in four steps on X and attached four sample pages drawn with it. Install Claude Code and Codex CLI on your PC and log in, paste the repo link and 「これ使えるようになって」 (set this up so I can use it) into Claude Code, then ask Claude how it works and go straight to asking for a manga. The sample is titled 「URLとひとことで漫画ができた話」 (How a URL and one line became a manga), and it draws that exact process as a manga. The image at the top of this article is its page 1.

The creator said they tuned the skill to turn out manga that read easily and feel steady, even without flashy panel layouts or art breaking out of the panels. That, they said, gives it the feel of the comic that runs on the last pages of a computer magazine.

The creator's first request

https://github.com/sa-san10/rimochan-nyamuru-manga-forge これ使えるようになって

Paste it into Claude Code as is.

Example request from the README

5ページの漫画を描いて。

Swap in your own page count and story. If you have art of your own character, include about three images.

How people reacted

What people liked

“我更喜欢这套东西留下的分镜文件。画面好看当然重要，但能改对白、改格序、换画风，再把同一段故事重新画出来，才值得继续用。”
What I like more is the storyboard file this setup leaves behind. Good-looking art matters, of course, but being able to rewrite the dialogue, reorder the panels, change the art style, and redraw the same story is what makes it worth sticking with.
From an article where they made a 2-page Chinese manga the same way, using a different image generation tool in place of the original script.

“做两三页的解释漫画、工具说明和生活短故事，这种结构化分镜值得试。”
For two- or three-page explainer comics, tool guides, and short slice-of-life stories, this kind of structured storyboard is worth a try.
方知微 (@superfang119) · X articlex.com
“--last を使わないので、他の codex 呼び出しが割り込んでも別の会話を掴まない”
Because it doesn't use --last, it won't grab a different conversation even if another codex call cuts in.
About how the skill continues the same Codex conversation from the previous page when it draws the next one. The editors checked setup and the scripts but did not run the drawing step.

“Claude Codeで画像まわりを触ると、環境準備で止まりがちだったので、喋るだけで漫画まで行ける入口があるのは嬉しいです。週末に試してみます。”
Whenever I worked with images in Claude Code, I tended to get stuck on environment setup, so I'm glad there's a way in where you just talk and get all the way to a manga. I'll try it this weekend.
Posted before trying it.

What fell short

“ここで情報量の調整とかできたら色々だぞ”
If you could adjust how much information goes in here, you could do a lot more with it.
Added when posting three pages generated in a single run.
ケイロカミオカ (@KeiroKamioka) · Xx.com
“猫相对人物的大小有变化”
The cat's size relative to the characters changes.
About a 2-page result made the same way, but with a different image generation tool in place of the original script.
方知微 (@superfang119) · X articlex.com
“它没有验证十页、几十页的长篇一致性”
It hasn't been tested for consistency over long works of ten or dozens of pages.
方知微 (@superfang119) · X articlex.com
“スクリプト3本は実行権限なし（100644）で登録されていた”
The three scripts were committed without execute permission (100644).
The script files did not have execute permission set. Based on the repo as downloaded on October 16.

How to start

Install Claude Code and Codex CLI and log in to both, then paste the request below into Claude Code. Claude Code works on paid Claude plans. Codex image generation works on ChatGPT Plus and above, not on Free. You have to log in to Codex yourself (codex login).

Starter prompt
Read the article at https://www.working-ref.com/en/reference/manga-forge-2026-10, then install the skill at https://github.com/sa-san10/rimochan-nyamuru-manga-forge so I can use it. If you get stuck during setup, read docs/pitfalls.md in the repo first and work it out from there. Then ask me one or two questions about my work and interests, and suggest three manga ideas worth trying at 2 to 5 pages. When I pick one, draw it right away. If none of them fit, start with the 2-page sample included in the repo.
While it draws, don't run other Codex jobs at the same time. Characters from another project can slip into your pages.[13]
