SBTI Personality Test & Claude Skill: A Complete Guide

What is SBTI?

SBTI (Super-Big Personality Test) is a humorous personality test originated from Chinese creator @蛆肉儿串儿 on Bilibili. Unlike traditional personality frameworks like MBTI, SBTI takes a irreverent, meme-laden approach to self-discovery — making it both entertaining and surprisingly insightful.

The test maps responses across 15 psychological dimensions organized into 5 models:

Model	Dimensions
Self Model	S1 Self-Esteem, S2 Self-Clarity, S3 Core Values
Emotional Model	E1 Attachment Security, E2 Emotional Investment, E3 Boundaries & Dependence
Attitude Model	A1 Worldview Tendency, A2 Rules & Flexibility, A3 Life Meaning
Action Drive Model	Ac1 Motivation Orientation, Ac2 Decision Style, Ac3 Execution Mode
Social Model	So1 Social Proactivity, So2 Interpersonal Boundaries, So3 Expression & Authenticity

Each dimension is scored on a 3-point scale (L=Low, M=Medium, H=High), producing a 15-character pattern like HHH-HMH-MHH-HHH-MHM. This pattern is then matched against 25 unique personality types — from CTRL (The Controller) to DRUNK (The Drunkard) — using Manhattan distance similarity scoring.

Some types are hidden and only triggered by specific answers (e.g., the DRUNK type activates if you indicate heavy alcohol consumption). Others serve as fallback options when the match is too loose (e.g., HHHH, the "Gigilord" — assigned when your brain pattern is so unique that the standard library refuses to categorize you).

What is a Claude Skill?

A Claude Skill is a lightweight, portable unit of functionality that extends Claude's capabilities. It consists of:

• A SKILL.md file — the manifest defining name, description, trigger words, and step-by-step instructions
• Supporting files — Python scripts, images, data, etc.
• Placed in ~/.claude/skills/ directory

Skills are invoked by users with slash commands (e.g., /sbti) and executed entirely within Claude's workflow — no external services, no API keys required.

How the SBTI Skill Was Built

Repository Structure

sbti-skill/
├── SKILL.md          # Skill manifest
├── sbti.py           # Core Python logic (questions + scoring)
└── image/            # 27 personality result images
    ├── CTRL.png
    ├── BOSS.png
    ├── DRUNK.png
    └── ...

Core Python Implementation (sbti.py)

The script is dependency-free (pure Python standard library) and exposes two commands:

# List all questions
python3 sbti.py questions

# Calculate personality from answers
echo '{"q1": 3, "q2": 1, ...}' | python3 sbti.py calc

The calc command:

1. Sums answers per dimension → converts to L/M/H level
2. Builds a 15-character user vector
3. Computes Manhattan distance against all 25 personality patterns
4. Applies special rules (drunk trigger, HHHH fallback)
5. Returns JSON with type code, name, description, image path, and dimension breakdown

Cross-Platform Considerations

To ensure the skill works on macOS, Linux, and Windows:

# Prefer uvx if available, fall back to python3
if command -v uvx &> /dev/null; then
  PY_CMD="uvx --from python python3"
else
  PY_CMD="python3"
fi

$PY_CMD sbti.py questions

For the result image, Downloads directory detection:

DOWNLOAD_DIR="$HOME/Downloads"
if [ ! -d "$DOWNLOAD_DIR" ]; then
  DOWNLOAD_DIR="$USERPROFILE/Downloads"  # Windows fallback
fi
cp ./image/${TYPE}.png "$DOWNLOAD_DIR/sbti_${TYPE}.png"

How to Use the SBTI Skill

Prerequisites

• Claude Code CLI installed
• Skill placed in ~/.claude/skills/sbti-skill/

Invocation

/sbti

Workflow

1. Welcome — Claude greets you and explains the test
2. Q&A — Claude asks all 30+ questions one by one, you respond with your choice (A/B/C/D)
3. Scoring — After the last question, Claude runs the calculation
4. Result — Claude outputs your personality type, description, 15-dimension breakdown, and saves the image to ~/Downloads/sbti_{TYPE}.png
