Use Case: Accessing and storing Workflow Data in Artifact File Directory

import os
import pandas as pd
import json

def run_tool(config, args):
    # ✅ Read input from workflow data directory
    workflow_data_dir = os.environ.get('WORKFLOW_DATA_DIRECTORY', '/workflow_data')
    input_file = os.path.join(workflow_data_dir, 'sales_data.csv')
    
    if not os.path.exists(input_file):
        return {"error": f"Input file not found: {input_file}"}
    
    # Process data
    df = pd.read_csv(input_file)
    summary = df.groupby('category').sum()
    
    # ✅ Write output to artifact file directory (using relative path)
    output_file = "sales_summary.csv"
    summary.to_csv(output_file, index=True)
    
    # ✅ Write JSON report to artifact file directory
    report_file = "report.json"
    with open(report_file, 'w') as f:
        json.dump({
            "status": "success",
            "total_rows": len(df),
            "categories": summary.index.tolist()
        }, f, indent=2)
    
    # Both files are automatically visible in Agent Studio UI
    return {
        "status": "success",
        "output_files": [output_file, report_file],
        "message": "Files created in artifact file directory"
    }
