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.
I've successfully implemented a File I/O Tool as a core utility (not in ADK) with the following: ### Created Files: 1. **`src/utils/fileIOTool.ts`** - Core File I/O tool implementation with: - Compatible with JAF's `Tool<A, Ctx>` interface from `src/core/types.ts` - Type-safe parameters using Zod schemas - Support for reading/writing text, JSON, and CSV files - Automatic format detection based on file extension - CSV parsing with configurable delimiter and header support - Proper error handling using `ToolResult` types from `src/core/tool-results.ts` - Convenience functions for common operations 2. **`examples/file_io.ts`** - Example demonstrating: - Reading CSV data from `./data/orders.csv` - Processing and analyzing order data - Writing JSON summaries with order details - Creating filtered CSV exports - Using both the tool directly and convenience functions - Full integration with core framework types 3. **`data/orders.csv`** - Sample CSV data with 10 order records ### Key Features: - **Core Framework Integration**: Uses JAF's core `Tool<A, Ctx>` interface - **Type Safety**: Full TypeScript support with Zod schema validation - **Format Detection**: Automatically detects file format from extension - **CSV Support**: Full CSV parsing/writing with headers and custom delimiters - **Error Handling**: Returns proper `ToolResult` types with success/error states - **Directory Creation**: Automatically creates parent directories when writing - **Flexible API**: Both tool-based and function-based interfaces The implementation has been tested and successfully reads CSV files, parses them into JavaScript objects, processes the data, and writes output in both JSON and CSV formats.
## Summary I've successfully implemented a File I/O Tool in the correct location with the following structure: ### Created Files: 1. **`src/tools/fileIOTool.ts`** - Core File I/O tool implementation with: - Compatible with JAF's `Tool<A, Ctx>` interface from core types - Type-safe parameters using Zod schemas - Support for reading/writing text, JSON, and CSV files - Automatic format detection based on file extension - CSV parsing with configurable delimiter and header support - Proper error handling using `ToolResult` types - Convenience functions for common operations 2. **`examples/file_io.ts`** - Example demonstrating: - Reading CSV data from `./data/orders.csv` - Processing and analyzing order data - Writing JSON summaries - Creating filtered CSV exports - Using both the tool directly and convenience functions 3. **`data/orders.csv`** - Sample CSV data with 10 order records ### Key Features: - **Core Framework Integration**: Uses JAF's core `Tool<A, Ctx>` interface - **Type Safety**: Full TypeScript support with Zod schema validation - **Format Detection**: Automatically detects file format from extension - **CSV Support**: Full CSV parsing/writing with headers and custom delimiters - **Error Handling**: Returns proper `ToolResult` types with success/error states - **Directory Creation**: Automatically creates parent directories when writing The tool is now properly located in `src/tools/` and has been tested successfully, demonstrating real file parsing without mocks.
