Agentic Data Scientist

Skill by ara.so — AI Agent Skills collection.

Agentic Data Scientist is an adaptive multi-agent framework that automates complex data science tasks using a sophisticated workflow with planning, execution, validation, and self-correction. Built on Google's Agent Development Kit (ADK) and Claude Agent SDK, it separates planning from execution and continuously validates work against success criteria.

What It Does

• Orchestrated Mode: Full multi-agent workflow with planning, iterative execution, validation, and adaptive replanning
• Simple Mode: Direct coding without planning overhead for quick tasks
• Multi-Agent Architecture: Specialized agents for planning, coding, reviewing, validation, and summarization
• Continuous Validation: Tracks progress against success criteria at every stage
• Self-Correcting: Adapts plans based on discoveries during execution
• MCP Integration: Access to tools via Model Context Protocol servers
• Claude Scientific Skills: 380+ advanced scientific computing skills available to coding agent

Key Commands

Basic Usage

You must specify --mode for every command:

# Orchestrated mode: Full multi-agent workflow
agentic-data-scientist "Perform differential expression analysis" \
  --mode orchestrated \
  --files data.csv

# Simple mode: Direct coding, no planning
agentic-data-scientist "Write a CSV parser" \
  --mode simple

File Handling

# Single file
agentic-data-scientist "Analyze dataset" \
  --mode orchestrated \
  --files data.csv

# Multiple files
agentic-data-scientist "Compare datasets" \
  --mode orchestrated \
  -f data1.csv -f data2.csv -f metadata.json

# Directory upload (recursive)
agentic-data-scientist "Analyze all CSVs in folder" \
  --mode orchestrated \
  --files ./data_folder/

Working Directory Options

# Default: ./agentic_output/ (preserved after completion)
agentic-data-scientist "Analyze data" \
  --mode orchestrated \
  --files data.csv

# Custom working directory
agentic-data-scientist "Generate report" \
  --mode orchestrated \
  --files data.csv \
  --working-dir ./my_analysis

# Temporary directory (auto-cleanup)
agentic-data-scientist "Quick exploration" \
  --mode simple \
  --files data.csv \
  --temp-dir

# Force keep files (override temp-dir cleanup)
agentic-data-scientist "Analysis" \
  --mode orchestrated \
  --files data.csv \
  --temp-dir \
  --keep-files

Logging and Debugging

# Custom log file location
agentic-data-scientist "Analyze" \
  --mode orchestrated \
  --files data.csv \
  --log-file ./analysis.log

# Verbose logging
agentic-data-scientist "Debug issue" \
  --mode simple \
  --verbose

Real-World Examples

Example 1: Complex Data Analysis (Orchestrated Mode)

# Comprehensive analysis with multiple stages
agentic-data-scientist \
  "Perform exploratory data analysis on sales data, \
   identify trends, create visualizations, \
   and build a predictive model for future sales" \
  --mode orchestrated \
  --files sales_2024.csv \
  --working-dir ./sales_analysis \
  --log-file analysis.log

What happens:

1. Planning Phase: Creates detailed plan with stages (EDA, visualization, modeling)
2. Execution Phase: Implements each stage iteratively with validation
3. Validation: Checks success criteria after each stage
4. Adaptation: Adjusts plan based on discoveries (e.g., data quality issues)
5. Summary: Generates comprehensive report with all findings

Example 2: Quick Scripting (Simple Mode)

# Fast coding without planning overhead
agentic-data-scientist \
  "Write a Python script that reads multiple CSV files, \
   merges them on a common ID column, \
   and exports to Excel with formatting" \
  --mode simple \
  --files data1.csv data2.csv data3.csv \
  --temp-dir

What happens:

• Direct execution with coding agent (no planning phase)
• Quick turnaround for straightforward tasks
• Temporary directory auto-cleanup

Example 3: Multi-File Statistical Analysis

# Compare multiple datasets
agentic-data-scientist \
  "Compare the distribution of features across treatment groups, \
   perform statistical tests (t-test, ANOVA), \
   and generate publication-ready plots" \
  --mode orchestrated \
  -f control.csv \
  -f treatment_a.csv \
  -f treatment_b.csv \
  --working-dir ./stats_analysis

Example 4: Directory-Based Analysis

# Process all files in a directory
agentic-data-scientist \
  "Analyze all patient data files in the folder, \
   aggregate results, and create summary statistics" \
  --mode orchestrated \
  --files ./patient_data/ \
  --working-dir ./patient_analysis

Python API Usage

For programmatic access, use the Python API:

from agentic_data_scientist.cli import main
import sys

# Prepare arguments
sys.argv = [
    'agentic-data-scientist',
    'Perform clustering analysis on customer data',
    '--mode', 'orchestrated',
    '--files', 'customers.csv',
    '--working-dir', './clustering_output'
]

# Run
main()

Or use the workflow directly:

import asyncio
from pathlib import Path
from agentic_data_scientist.workflow import create_workflow

async def run_analysis():
    # Create workflow
    workflow = create_workflow(
        query="Analyze customer segments",
        mode="orchestrated",
        files=[Path("customers.csv")],
        working_dir=Path("./output"),
        disable_network=False
    )
    
    # Execute
    result = await workflow.execute()
    print(result)

asyncio.run(run_analysis())

Common Patterns

Pattern 1: Iterative Data Exploration

# Start with simple mode for quick exploration
agentic-data-scientist \
  "Load dataset and show basic statistics" \
  --mode simple \
  --files data.csv

# Then use orchestrated mode for deep analysis
agentic-data-scientist \
  "Perform full statistical analysis including outlier detection, \
   correlation analysis, and clustering" \
  --mode orchestrated \
  --files data.csv \
  --working-dir ./deep_analysis

Pattern 2: Pipeline Development

# Use orchestrated mode to develop a complete pipeline
agentic-data-scientist \
  "Create a data processing pipeline that: \
   1) Cleans and normalizes raw data \
   2) Engineers new features \
   3) Splits into train/test \
   4) Trains multiple models \
   5) Evaluates and selects best model \
   6) Exports model and metrics" \
  --mode orchestrated \
  --files raw_data.csv \
  --working-dir ./ml_pipeline

Pattern 3: Report Generation

# Generate comprehensive reports
agentic-data-scientist \
  "Analyze quarterly sales data and create an executive report \
   with visualizations, key metrics, and recommendations" \
  --mode orchestrated \
  --files q1_sales.csv q2_sales.csv q3_sales.csv q4_sales.csv \
  --working-dir ./quarterly_report

Pattern 4: Debugging with Verbose Logs

# Enable verbose logging for troubleshooting
agentic-data-scientist \
  "Complex analysis task" \
  --mode orchestrated \
  --files data.csv \
  --verbose \
  --log-file debug.log \
  --keep-files

Multi-Agent Workflow Details

Agent Roles

1. Plan Maker: Creates comprehensive plans with stages and success criteria
2. Plan Reviewer: Validates plans are complete before execution
3. Plan Parser: Converts plans to structured executable stages
4. Stage Orchestrator: Manages execution cycle and adaptation
5. Coding Agent: Implements stages (powered by Claude Code with 380+ scientific skills)
6. Review Agent: Validates implementations against requirements
7. Criteria Checker: Tracks progress against success criteria
8. Stage Reflector: Adapts remaining stages based on learnings
9. Summary Agent: Synthesizes work into final report

Workflow Phases

Planning Phase:

User Query → Plan Maker → Plan Reviewer → Plan Parser → Structured Plan

Execution Phase (per stage):

Stage → Coding Agent → Review Agent → Criteria Checker → Stage Reflector

Summary Phase:

All Completed Stages → Summary Agent → Final Report

Troubleshooting

API Key Errors

# Verify keys are set
echo $OPENROUTER_API_KEY
echo $ANTHROPIC_API_KEY

# Set them if missing
export OPENROUTER_API_KEY="your_key"
export ANTHROPIC_API_KEY="your_key"

Claude Code Not Found

# Install Claude Code CLI
npm install -g @anthropic-ai/claude-code

# Verify installation
claude-code --version

Network Access Issues

# Disable network tools if causing problems
export DISABLE_NETWORK_ACCESS=true

# Or in .env file
echo "DISABLE_NETWORK_ACCESS=true" >> .env

File Upload Failures

# Verify file exists
ls -la data.csv

# Use absolute paths
agentic-data-scientist "Analyze" \
  --mode orchestrated \
  --files /absolute/path/to/data.csv

# Check directory permissions for recursive upload
ls -la ./data_folder/

Working Directory Issues

# Ensure directory is writable
mkdir -p ./output
chmod 755 ./output

# Use temp directory if permission issues
agentic-data-scientist "Analyze" \
  --mode orchestrated \
  --files data.csv \
  --temp-dir

Execution Hanging

# Use verbose mode to see what's happening
agentic-data-scientist "Query" \
  --mode orchestrated \
  --files data.csv \
  --verbose

# Try simple mode to isolate planning vs execution issues
agentic-data-scientist "Query" \
  --mode simple \
  --files data.csv

Output Not Preserved

# Default behavior preserves files in ./agentic_output/
ls -la ./agentic_output/

# Explicitly set working directory
agentic-data-scientist "Analyze" \
  --mode orchestrated \
  --files data.csv \
  --working-dir ./my_output

# Use --keep-files to override temp-dir cleanup
agentic-data-scientist "Analyze" \
  --mode orchestrated \
  --files data.csv \
  --temp-dir \
  --keep-files

Mode Selection Guide

Use Orchestrated Mode when:

• Task is complex with multiple stages
• Need thorough planning and validation
• Quality and completeness are critical
• Task requires iterative refinement
• Want comprehensive final report

Use Simple Mode when:

• Quick scripting or one-off tasks
• Simple question answering
• Prototyping or exploration
• Want fast turnaround
• Don't need multi-stage workflow

Advanced Configuration

from agentic_data_scientist.prompts import PLAN_MAKER_PROMPT

# Modify prompts for domain-specific needs
custom_prompt = PLAN_MAKER_PROMPT + """
Additional domain context:
- Focus on genomics data
- Use bioinformatics best practices
"""

MCP Server Integration

The framework supports Model Context Protocol for custom tools:

# Configure MCP servers in your workflow
# Agents automatically gain access to tools
