# DataRobot Feature Engineering Skill

This skill provides guidance for working with features in DataRobot, including understanding automated feature engineering, analyzing feature importance, and optimizing feature sets.

## Quick Start

**Most common use case**: Analyze feature importance for a model

1. **Get feature importance**: `get_feature_importance(model_id)` to get importance scores
2. **Analyze top features**: Sort by importance and identify key drivers
3. **Export feature list**: `export_feature_list(project_id)` to document features

**Example**: "Show me the top 10 most important features for model xyz123"

## When to use this skill

Use this skill when you need to:
- Understand what features DataRobot creates automatically
- Analyze feature importance for models
- Discover which features drive predictions
- Optimize feature sets for better performance
- Understand feature types and transformations
- Export feature lists and definitions

## Key capabilities

### 1. Feature Discovery

- Understand automated feature engineering in DataRobot
- Review derived features and transformations
- Identify feature types (numeric, categorical, text, date)
- Explore feature relationships and interactions

### 2. Feature Importance Analysis

- Get feature importance scores for models
- Understand which features drive predictions
- Compare feature importance across models
- Identify redundant or low-value features

### 3. Feature Optimization

- Select important features for model performance
- Remove low-importance features to reduce complexity
- Understand feature impact on predictions
- Optimize feature sets for deployment

### 4. Feature Documentation

- Export feature lists and definitions
- Document feature transformations
- Understand feature derivation logic
- Share feature information with stakeholders

## Workflow examples

### Example 1: Analyze feature importance

**User request**: "Show me the top 10 most important features for model xyz123 and explain what they mean."

**Agent workflow**:
1. Get feature importance scores for the model
2. Sort features by importance (descending)
3. Get top 10 features with their scores
4. Retrieve feature metadata and descriptions
5. Explain what each feature represents and why it's important
6. Provide insights on feature relationships

### Example 2: Optimize feature set for deployment

**User request**: "Create a simplified feature set for deployment abc123, keeping only features with importance > 0.1."

**Agent workflow**:
1. Get feature importance for the deployed model
2. Filter features by importance threshold (> 0.1)
3. Verify filtered features are sufficient for predictions
4. Document the optimized feature set
5. Update deployment configuration if needed

## Using DataRobot SDK

This skill guides you to use the DataRobot Python SDK directly. Install the SDK if needed:

```bash
pip install datarobot
```

### Key SDK Operations

Use these DataRobot SDK methods for feature analysis:

**Feature Information**:
- `model.get_features()` - List all features in a model
- `model.get_feature_impact()` - Get feature importance scores
- `project.get_features()` - List features in a project

**Feature Analysis**:
- `feature.name` - Feature name
- `feature.feature_type` - Feature type (Numeric, Categorical, etc.)
- `feature.importance` - Feature importance score

See the [Common Patterns](#common-patterns) section below for complete examples.

## Best practices

1. **Review automated features**: DataRobot creates many derived features automatically - review them
2. **Focus on important features**: Pay attention to high-importance features for insights
3. **Understand feature types**: Different feature types require different handling
4. **Feature documentation**: Document important features for stakeholders
5. **Feature selection**: Consider removing very low-importance features for simplicity
6. **Feature stability**: Consider feature stability over time, not just importance

## Common patterns

### Pattern 1: Feature importance analysis
