TCM Constitution Analyzer - A Claude Skill for Nine Constitution Types Identification and Health Recommendations

TCM Constitution Analyzer: A Health Tool Hidden in GitHub

Recently, while organizing my skill library, I stumbled upon a rather interesting Claude Skill project — the TCM Constitution Analyzer. To be honest, at first I thought it was one of those flashy but useless things, but upon closer inspection, this thing actually has some substance.

This skill was created by the developer foolhardy45 and is stored in their portfolio repository, under the path .claude/skills/tcm-constitution-analyzer. Although the repo only contains a single SKILL.md file, just from the name you can guess what it does — it helps you analyze your constitution according to traditional Chinese medicine (TCM) and gives you health recommendations. And because it's a Claude Skill, it's super convenient to use — you can do everything right in a conversation.

What Can It Actually Do?

I'm sure many of you have heard of the "nine constitutions" in TCM, right? They are: Balanced Constitution, Qi Deficiency, Yang Deficiency, Yin Deficiency, Phlegm-Dampness, Damp-Heat, Blood Stasis, Qi Stagnation, and Allergic Constitution. In the past, if you wanted to figure out your constitution, you had to either visit a TCM doctor for a full diagnosis (looking, listening, asking, and pulse-taking), or install a bunch of messy apps on your phone, which often risked leaking your privacy.

This skill is different — you just chat with Claude and answer a few questions, like:

• Do you often feel tired easily?
• Are your hands and feet frequently cold?
• Is your stool often loose or unformed?
• Does your tongue coating look thick?

Then, based on your responses, Claude will comprehensively assess your constitution type and give you very specific advice — such as what foods to eat, what exercises are suitable, and what emotional adjustments to pay attention to. I tried it myself, and I think it's even more reliable than some paid constitution-testing apps (at least it won't try to sell you health supplements).

How to Install and Use?

This skill is open source, hosted on GitHub, and installation is very straightforward:

npx skills add https://github.com/foolhardy45/portfolio.git --skill tcm-constitution-analyzer

If you prefer using SSH, you can also do:

npx skills add [email protected]:foolhardy45/portfolio.git --skill tcm-constitution-analyzer

After installation, simply type "Start constitution test" or "Analyze my constitution" in Claude's chat interface, and the skill will automatically load and begin a conversation with you. The whole process feels like chatting with a friend, without the boredom of filling out a questionnaire.

What's interesting is that it doesn't throw all the questions at you at once — instead, it dynamically adjusts subsequent questions based on your answers. For example, if you say "I often have cold hands and feet," it might follow up with "Do you also experience soreness in your lower back and knees?" or "Do you tend to get diarrhea after eating cold or raw foods?" This interactive approach makes the test results more accurate and feels more natural.

Experience and Precautions

The first time I used it, Claude asked me, "Do you prefer warm or cold food?" I answered "Warm," and it continued, "Do you feel uncomfortable after eating cold things?" In the end, it identified me as having Yang Deficiency. The recommendations included: drink more ginger and brown sugar water, eat less watermelon and other cooling foods, and do morning jogs or Ba Duan Jin (a traditional Chinese exercise). Well, I must say, these suggestions really fit my lifestyle.

However, I need to remind everyone: this skill is only a health reference and cannot replace a doctor's diagnosis. If you have obvious physical discomfort — such as persistent fatigue, pain, or severe sleep problems — you should definitely visit a proper hospital. TCM constitution analysis is more about helping you understand your constitutional tendencies so you can consciously adjust your lifestyle habits — it belongs to the realm of preventive health care.

Also, all conversation data is stored only within the current session. Claude does not upload your health data to any server (unless you actively share it), so you can feel relatively safe about privacy.

Who Is It For?

I think the following groups of people will particularly enjoy this skill:

• TCM enthusiasts — those who want to systematically learn constitution identification but can't find a good tool.
• Health-conscious people — those who already pay attention to diet and exercise and want to fine-tune their regimen.
• Office workers — those who often stay up late, are in suboptimal health, and want to know their constitution type.
• Health management professionals — they can use it as a supplementary tool to help clients quickly understand their constitution.

Of course, if you're someone who "doesn't believe in TCM," then this skill may not be for you. But hey, it's never a bad thing to learn a bit about traditional medical wisdom — maybe you'll discover something new.

A Little Easter Egg

While testing, I found that this skill also supports multi-turn follow-up questions. For example, after I was diagnosed as Qi Deficiency, I asked, "Would it be helpful to drink astragalus (Huang Qi) water regularly?" Claude, based on the previous analysis, went on to give me even more detailed advice — including the dosage of astragalus, what herbs to combine it with, and when it's not suitable to drink it. This feature is really practical — it's like having a portable TCM consultant by your side.

In short, if you have a Claude environment, give this skill a try. It's open source and free, and installation takes just a few seconds. After you use it, feel free to share in the comments what constitution you were diagnosed with — let's see which of the nine types is the most common 😄
