feat: Complete data_processing pipeline implementation (Issue #163)

jeremymanning · jeremymanning · commit 76f9df19f6f3 · 2025-08-16T09:55:53.000-04:00
- Fixed tool registration (ValidationTool and DataProcessingTool already registered) - Created test data files (JSON and CSV) in examples/test_data/ - Rewrote pipeline YAML to fix template syntax and tool usage - Enhanced DataProcessingTool to handle filter and aggregate transformations - Added JSON parsing to ValidationTool and DataProcessingTool - Created comprehensive test suite with 23 tests (NO MOCKS) - All data processing uses real file I/O and transformations Test categories: - Core functionality (10 tests) - Edge cases (8 tests) - Error handling (5 tests) Pipeline now successfully: - Loads JSON/CSV data - Validates against schemas - Filters records by criteria - Aggregates numeric fields - Saves processed data - Generates reports Issue #163
