  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by OpenSenseNova on GitHub. Read the source before you install it.

Installation

Install the Numeric Extraction And Distribution Analysis AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/OpenSenseNova/SenseNova-Skills.git /tmp/SenseNova-Skills
mkdir -p .claude/skills
cp -r /tmp/SenseNova-Skills/skills/sn-da-excel-workflow/capability/excel-conditional-formatting/data-bar-formatting .claude/skills/numeric-extraction-and-distribution-analysis
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Numeric Extraction And Distribution Analysis in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Numeric Extraction And Distribution Analysis on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Numeric Extraction And Distribution Analysis is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Skill Steps

Step1 从原始数据中提取目标列,清理无效和空值数据,并安全地将带单位的字符串转换为数值类型

python
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

# 配置中英文字体,避免图表乱码
plt.rcParams['font.sans-serif'] = ['SimHei', 'DejaVu Sans']
plt.rcParams['axes.unicode_minus'] = False

item_col = '项目名称'  # 占位示例:分类或名称列
value_col = '带单位的数值'  # 占位示例:需要提取数值的原始列
numeric_col = '提取数值'
unit_str = 'g'  # 占位示例:需要移除的单位字符串

def extract_numeric_value(val_str):
    """从带单位的字符串中提取数值"""
    if pd.isna(val_str):
        return None
    try:
        # 移除单位并转换为浮点数
        return float(str(val_str).replace(unit_str, '').strip())
    except ValueError:
        return None

# 清理缺失值与异常占位符
df_clean = df.dropna(subset=[item_col, value_col]).copy()
df_clean = df_clean[df_clean[item_col] != '...']

# 应用提取函数并过滤转换失败的行
df_clean[numeric_col] = df_clean[value_col].apply(extract_numeric_value)
df_clean = df_clean.dropna(subset=[numeric_col])

Step2 创建基础分布直方图,并添加平均值和中位数的参考线以展示数据的集中趋势

python
plt.figure(figsize=(12, 8))

# 绘制直方图
plt.hist(df_clean[numeric_col], bins=10, alpha=0.7, color='skyblue', edgecolor='black')

# 计算并添加平均值和中位数参考线
mean_val = df_clean[numeric_col].mean()
median_val = df_clean[numeric_col].median()
plt.axvline(mean_val, color='red', linestyle='--', linewidth=2, label=f'平均值: {mean_val:.2f}')
plt.axvline(median_val, color='green', linestyle='--', linewidth=2, label=f'中位数: {median_val:.2f}')

plt.xlabel(f'{numeric_col}', fontsize=12)
plt.ylabel('频数', fontsize=12)
plt.title(f'{numeric_col}分布直方图', fontsize=14, fontweight='bold')
plt.legend()
plt.grid(True, alpha=0.3)
plt.show()

Step3 生成包含直方图、饼图、条形图和累积分布图的综合分析面板,全面展示数值的分布特征并保存高分辨率图片

python
# 创建 2x2 子图布局
fig, ((ax1, ax2), (ax3, ax4)) = plt.subplots(2, 2, figsize=(16, 12))

# 1. 直方图
ax1.hist(df_clean[numeric_col], bins=8, alpha=0.7, color='lightblue', edgecolor='black', rwidth=0.8)
ax1.set_xlabel(f'{numeric_col}', fontsize=12)
ax1.set_ylabel('频数', fontsize=12)
ax1.set_title(f'{numeric_col}分布直方图', fontsize=14, fontweight='bold')
ax1.grid(True, alpha=0.3)

# 2. 饼图 (基于 value_counts 统计占比)
val_counts = df_clean[numeric_col].value_counts().sort_index()
colors = plt.cm.Set3(np.linspace(0, 1, len(val_counts)))
ax2.pie(val_counts.values, labels=[f'{x}' for x in val_counts.index], autopct='%1.1f%%', colors=colors, startangle=90)
ax2.set_title(f'{numeric_col}占比分布', fontsize=14, fontweight='bold')

# 3. 条形图
val_counts.plot(kind='bar', ax=ax3, color='lightcoral', alpha=0.8)
ax3.set_xlabel(f'{numeric_col}', fontsize=12)
ax3.set_ylabel('数量', fontsize=12)
ax3.set_title(f'各{numeric_col}对应的数量', fontsize=14, fontweight='bold')
ax3.tick_params(axis='x', rotation=45)
ax3.grid(True, alpha=0.3)

# 4. 累积分布图
sorted_values = np.sort(df_clean[numeric_col])
cumulative_freq = np.arange(1, len(sorted_values) + 1) / len(sorted_values) * 100
ax4.plot(sorted_values, cumulative_freq, marker='o', linewidth=2, markersize=6, color='darkgreen')
ax4.set_xlabel(f'{numeric_col}', fontsize=12)
ax4.set_ylabel('累积百分比 (%)', fontsize=12)
ax4.set_title(f'{numeric_col}累积分布', fontsize=14, fontweight='bold')
ax4.grid(True, alpha=0.3)

# 调整布局并保存
plt.tight_layout()
output_path = 'distribution_dashboard.png'
plt.savefig(output_path, dpi=300, bbox_inches='tight')
plt.show()

Frequently asked questions

What does the Numeric Extraction And Distribution Analysis AI skill do?

从带单位的字符串列中提取数值并清洗,生成包含直方图、饼图、条形图和累积分布图的多维度综合分布可视化图表,用于展示数据的集中趋势与分布特征。

Why use Numeric Extraction And Distribution Analysis on TypingMind?

Because you install it once and use it with any model. Numeric Extraction And Distribution Analysis is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Numeric Extraction And Distribution Analysis in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/OpenSenseNova/SenseNova-Skills/tree/main/skills/sn-da-excel-workflow/capability/excel-conditional-formatting/data-bar-formatting. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Numeric Extraction And Distribution Analysis?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Numeric Extraction And Distribution Analysis?

As many as you like. As long as a model supports skills, you can use Numeric Extraction And Distribution Analysis with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Numeric Extraction And Distribution Analysis AI skill free?

Yes. It is published on GitHub by OpenSenseNova under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
