From f68f2e6ea93af95750dc799e44e7f767c2a43707 Mon Sep 17 00:00:00 2001 From: Anurag Sharan Date: Tue, 9 Sep 2025 23:00:44 +0530 Subject: [PATCH 1/3] ## Summary I've successfully implemented a File I/O Tool for the JAF framework with the following features: ### Created Files: 1. **`src/adk/tools/fileIOTool.ts`** - The main tool implementation with: - Support for reading and writing text, JSON, and CSV files - Automatic format detection based on file extension - CSV parsing with configurable delimiter and header support - JSON serialization/deserialization - Error handling and validation - Convenience functions for common operations (readTextFile, readJSONFile, readCSVFile, writeTextFile, writeJSONFile, writeCSVFile) 2. **`examples/file_io.ts`** - Example demonstrating: - Reading CSV data from `./data/orders.csv` - Processing and analyzing the data - Writing JSON summaries - Creating filtered CSV exports - Using both the tool directly and convenience functions 3. **`data/orders.csv`** - Sample CSV data file with 10 order records 4. **`test-file-io.mjs`** - Standalone test script that successfully demonstrates all functionality ### Key Features: - **Format Detection**: Automatically detects file format from extension (.json, .csv, .txt) - **CSV Support**: Full CSV parsing with headers and custom delimiters - **Directory Creation**: Automatically creates parent directories when writing files - **Type Safety**: Fully typed with TypeScript interfaces - **Error Handling**: Comprehensive error handling with detailed error messages - **Flexible API**: Both tool-based and function-based interfaces The implementation successfully reads CSV files, parses them into JavaScript objects, processes the data, and writes output in both JSON and CSV formats, as demonstrated by the test run. --- data/completed_orders.csv | 6 + data/order_summary.json | 124 +++++++++++++++ data/orders.csv | 11 ++ data/report.json | 11 ++ examples/file_io.ts | 167
