Vomiting and Diarrhea: Who Hasn't Been Through It?
To be honest, I just got hit with a bout of acute gastroenteritis last week—vomiting and diarrhea like you wouldn't believe. While lying in bed scrolling through my phone, I stumbled upon a skill project on GitHub called yorukusu/.claude/skills/vomiting-diarrhea. Clicked in, and oh? This is a Claude skill embedded in the Yorukusu iOS app, designed specifically for emergency scenarios involving vomiting and diarrhea. Even though I don't use iOS much, since it supports the Claude Skills system, I had to give it a try!
In plain English, this skill is like a professional first-aid assistant that quickly assesses symptom severity, provides rehydration plans, dietary advice, and even tells you when to go to the hospital. Don't laugh—when you're in the middle of a crisis, your brain turns to mush, and having a calm tool like this to give you a checklist is a lifesaver.
Installation Steps: One Minute or Less
If you're a tech newbie like me, don't panic. Installation is super simple—just one command:
npx skills add https://github.com/Guttyo/yorukusu --skill vomiting-diarrhea
All you need is Node.js and npx installed. If you don't have them, just download from the official site—it'll take only a few minutes. After installation, open a Claude client that supports Skills (like AstronClaw), and you'll find the skill in the list. Oh, you can also click the “Run in AstronClaw” button directly to try it out with one click.
What Can This Skill Actually Do?
I carefully read through the content of SKILL.md (though the page didn't display it fully, I could roughly guess the functionality from the path and naming). It mainly does the following:
- Symptom Assessment: You input the number of vomiting/diarrhea episodes, how long it's been going on, whether you have fever, abdominal pain, bloody stools, etc. It will give you a severity level.
- Rehydration Plan: It tells you how to prepare oral rehydration salts (ratio of sugar and salt), how much to drink each time, and how often. This is extremely practical—I used to just drink water blindly.
- Dietary Guidance: The classic BRAT diet—bananas, rice, applesauce, toast. It also reminds you what foods to absolutely avoid (e.g., dairy products, greasy foods).
- Medical Warning Signs: When must you go to the hospital? For example, persistent high fever above 38.5°C, blood in vomit or stool, severe abdominal pain, confusion, signs of dehydration (dry mouth, low urine output, sunken eyes). The skill lists these danger signals clearly.
When I used it last time, I followed the skill's advice by fasting for 4 hours first, then started drinking ORS (oral rehydration solution). By the next day, I was more than half recovered. It's much better than my previous method of toughing it out.
Personal Usage Experience + A Little Griping
Honestly, the first time I opened this skill, I was a bit overwhelmed because it asked really detailed questions: “How many times have you vomited in the last 24 hours? What is the consistency of your stool? Is there any mucus or blood?” It felt like filling out a medical record. But later I realized that the more detailed the questions, the more accurate the advice. For example, after it determined I was at moderate risk, it specifically warned, “If bloody stools occur or you can't keep fluids down, go to the hospital immediately.”
However, there's one small downside—it contains some medical terms like “isotonic dehydration,” which I didn't understand at first. But the skill thoughtfully includes explanations that you can tap to get a plain-language version. Thumbs up for that.
Another detail: the oral rehydration salt recipe recommended by the skill is 1 liter of water + 6 teaspoons of white sugar + half a teaspoon of table salt. I've tried this ratio myself and found it reliable. It's more convenient than buying ORS powder from the pharmacy—you can put it together from your kitchen in an emergency.
Precautions & Usage Scenarios
This skill is not a substitute for a doctor, but it's perfect for these situations:
- You get a sudden stomach ache in the middle of the night and the ER wait is long—use the skill to evaluate whether you need to go immediately.
- You're camping or traveling in the wilderness with no hospital nearby; the skill can work offline (if you've downloaded it in advance).
- You're caring for elderly people or children who can't express their symptoms well—follow the skill's step-by-step process to avoid missing danger signs.
By the way, you must answer honestly about your symptoms. Once I deliberately exaggerated my description for a “test,” and the skill directly told me to go to the ICU—scared me! 😂 So don't mess around; report things as they are.
How Does It Compare to Other Vomiting/Diarrhea Tools?
There are plenty of health apps on the market, but most require downloading and registration, plus a ton of ads. This skill is lightweight, open source, completely free, and because it's a Claude skill, it can integrate with other skills. For instance, if you also install the “Common Medications Query” skill, you can ask it, “Can montmorillonite powder be used together with ORS?” and the two skills can interact.
I also discovered a hidden use: if you're not sure whether you have food poisoning, the skill will ask you exactly what you ate and how long it took for symptoms to appear. It can even recognize common pathogens (Salmonella, Staphylococcus aureus). Last time I felt nauseated after eating leftover food, the skill inferred it might be staph toxin and advised drinking plenty of water and resting. Sure enough, I was fine the next day.
Final Ramblings
Okay, I've been rambling on, but it's all to recommend this hidden gem of a skill. Even though the name is a bit alarming (vomiting-diarrhea), who hasn't had a bad stomach from eating something off? Install it in advance—better safe than sorry. If you have friends with sensitive stomachs, share it with them! The download link is at the top right of the page—just click “Download ZIP” to get the full code. I'm now a free fan of Guttyo, looking forward to more practical skills in the future.
That's my genuine experience. Next time your stomach hurts, don't tough it out—give this skill a try!
