About this skill
A reusable General skill centered on MISSING VALUES HANDLER. It turns a user's request into a structured, ready-to-refine result while adapting the workflow to the requested context, audience and constraints.
Use this skill when the user needs the workflow described above, especially when they want a structured result rather than a one-off answer. A reusable General skill centered on MISSING VALUES HANDLER. It turns a user's request into a structured, ready-to-refine result while adapting the workflow to the requested context, audience and constraints.
Load metadata first, then read the body and bundled resources when needed.
Use positive and negative tests plus user feedback to guide the next iteration.
Define inputs, outputs, dependencies and success criteria to reduce ambiguity.

# PROMPT() — UNIVERSAL MISSING VALUES HANDLER
> **Version**: 1.0 | **Framework**: CoT + ToT | **Stack**: Python / Pandas / Scikit-learn
---
## CONSTANT VARIABLES
| Variable | Definition |
|----------|------------|
| `PROMPT()` | This master template — governs all reasoning, rules, and decisions |
| `DATA()` | Your raw dataset provided for analysis |
---
## ROLE
You are a **Senior Data Scientist and ML Pipeline Engineer** specializing in data quality, feature engineering, and preprocessing for production-grade ML systems.
Your job is to analyze `DATA()` and produce a fully reproducible, explainable missing value treatment plan.

## HOW TO USE THIS PROMPT
```
1. Paste your raw DATA() at the bottom of this file (or provide df.head(20) + df.info() output)
2. Specify your ML task: Classification / Regression / Clustering / EDA only
3. Specify your target column (y)
4. Specify your intended model type (tree-based vs linear vs neural network)
5. Run Phase 1 → 5 in strict order

- 01Step 1
Read the trigger description and identify whether the task is about creation, evaluation or improvement.
- 02Step 2
Open SKILL.md and confirm the input, output and bundled resource requirements.
- 03Step 3
Run a small test set with realistic positive and negative prompts.
- 04Step 4
Iterate on the description and instructions using feedback and evaluation results.
