Just one RL example of using Claude Code

[Javier Tarí 33]

This is a real example, not even a chosen one. It's to show not the programming itself, but just to show how is it to work with Claude Code

Note: some of the identifiers are spanish, as I'm spanish and I tend to mix spanish and english in my code. Strings that interact with the user in any way are in spanish, because the suers are spanish

 

Inside one of my ERP application folders, there is a group of units that help the user with inserting them in the system. They handle PDF of the Purchase Invoices, use IA on them, and reduce the user work by around 80-95%. It's fully finished, although will have further refinements.

There is a file documenting them, called ganProveedoresFacturaRapida.md

 

I jsut gave Claude this prompt:

"read ganProveedoresFacturaRapida.md; we will refactor it for good practices, starting with DRY"

and it presented me a plan

Then instead of appying it, I made a new prompt:

"Make redactoring-plan.md with your plan, and anything else needed so another IA agent can implement it just by
  reading the main documentation and this .md"

It's answer:

● I'll create a comprehensive refactoring plan document that another AI agent can follow to implement the DRY
  improvements.

     # DRY Refactoring Plan for ganProveedoresFacturaRapida Module
     ## Executive Summary
     This document provides a detailed plan to refactor the `ganProveedoresFacturaRapida` module to eliminate code
     duplication and improve maintainability following DRY (Don't Repeat Yourself) principles. The module currently
     has ~2500 lines with significant repetition that can be reduced by ~30%.
     ## Current State Analysis
     ### Module Overview
     - **Purpose**: AI-powered rapid supplier invoice entry system
     … +729 lines (ctrl+o to expand)

● I've created a comprehensive refactoring plan document at
  /mnt/w/Clientes/GAN/ganProveedoresFacturaRapida-refactoring-plan.md.

  The document includes:

  1. Executive Summary - Overview of the refactoring goals and expected improvements
  2. Current State Analysis - Detailed list of DRY violations with code examples
  3. Refactoring Design - New architecture with helper classes and services
  4. Implementation Plan - Three-phase approach with complete code samples for new classes
  5. Migration Guide - Step-by-step instructions for developers
  6. Code Mapping Table - Shows exactly how to replace old patterns with new ones
  7. Risk Assessment - Identifies potential issues and mitigation strategies
  8. Testing Plan - Unit, integration, and regression testing approach
  9. Code Examples - Before/after comparisons showing the improvements

  The plan provides everything needed for another AI agent or developer to implement the refactoring:
  - Complete class definitions with methods
  - Clear mapping of old code to new patterns
  - Specific file locations and naming conventions
  - Testing requirements
  - Expected metrics (30% code reduction, improved maintainability)

  The refactoring follows DRY principles by consolidating repeated patterns into reusable helper classes:
  - TInvoiceFileHelper - All file operations
  - TTimeoutManager - Timeout and retry logic
  - TStatusManager - UI status updates
  - TBatchProcessor - Batch processing service
  - TAnalysisConfig - Centralized configuration

  This approach will transform the module from procedural code with 40% duplication to a well-structured,
  object-oriented design with less than 10% duplication.
