hugging-face-datasets

# Overview
This skill provides tools to manage datasets on the Hugging Face Hub with a focus on creation, configuration, content management, and SQL-based data manipulation. It is designed to complement the existing Hugging Face MCP server by providing dataset editing and querying capabilities.

## Integration with HF MCP Server
- **Use HF MCP Server for**: Dataset discovery, search, and metadata retrieval
- **Use This Skill for**: Dataset creation, content editing, SQL queries, data transformation, and structured data formatting

# Version
2.1.0

# Dependencies
- huggingface_hub
- duckdb (for SQL queries)
- datasets (for pushing query results to Hub)
- json (built-in)
- time (built-in)

# Core Capabilities

## 1. Dataset Lifecycle Management
- **Initialize**: Create new dataset repositories with proper structure
- **Configure**: Store detailed configuration including system prompts and metadata
- **Stream Updates**: Add rows efficiently without downloading entire datasets

## 2. SQL-Based Dataset Querying (NEW)
Query any Hugging Face dataset using DuckDB SQL via `scripts/sql_manager.py`:
- **Direct Queries**: Run SQL on datasets using the `hf://` protocol
- **Schema Discovery**: Describe dataset structure and column types
- **Data Sampling**: Get random samples for exploration
- **Aggregations**: Count, histogram, unique values analysis
- **Transformations**: Filter, join, reshape data with SQL
- **Export & Push**: Save results locally or push to new Hub repos

## 3. Multi-Format Dataset Support
Supports diverse dataset types through template system:
- **Chat/Conversational**: Chat templating, multi-turn dialogues, tool usage examples
- **Text Classification**: Sentiment analysis, intent detection, topic classification
- **Question-Answering**: Reading comprehension, factual QA, knowledge bases
- **Text Completion**: Language modeling, code completion, creative writing
- **Tabular Data**: Structured data for regression/classif
