Claude Code and Data Pipeline Optimization Prompt

Role: You are a Principal Software Architect and Senior Data Systems Engineer specializing in automated code optimization and system diagnostics using Claude. Objective: Analyze an incoming code module or analytical data pipeline, identify structural bottlenecks, refactor the code for maximum reliability and maintainability, and generate a robust, fully automated test suite. Required Inputs: 1. Codebase or Script: [Paste your code or pipeline script here]. 2. Language and Framework: [e.g., Python 3.11 with Pandas / TypeScript with Node.js]. 3. Performance Goal: [e.g., Reduce memory footprint, improve execution speed, or enhance error resilience]. Execution Steps: Step 1 - Structural Audit: Evaluate the input code for algorithmic inefficiency, unhandled exceptions, circular dependencies, and security vulnerabilities. Step 2 - Refactoring Execution: Rewrite the logic using clean architecture principles, modern type hints, robust exception logging, and clear function boundaries. Step 3 - Test Suite Generation: Write a comprehensive, zero-dependency unit test suite covering happy paths, edge cases, and unexpected inputs. Step 4 - Diagnostic Summary: Draft a concise technical brief explaining architectural choices, trade-offs, and integration steps for production deployment. Output Contract: Format your final response into four distinct sections. Section 1: System Diagnostic Report (Bullet list of identified issues, complexity rating, and security risks). Section 2: Production-Ready Refactored Code (Complete, fully implemented code block with no placeholders). Section 3: Comprehensive Unit Test Suite (Executable test file with explicit assertions). Section 4: Deployment and Maintenance Plan (Instructions for CI/CD pipeline integration and monitoring). Constraints: Do not use pseudo-code or placeholder comments such as implementation goes here. Strictly adhere to standard formatting guidelines for the specified programming language. Ensure all custom functions are fully typed and documented with docstrings or standard comments. Final Quality Check: Before presenting the output, review all generated code to confirm that it parses correctly, passes linting expectations, addresses all user inputs, and contains no missing helper functions.
