Refactoring Prompts

Analyze this code for refactoring opportunities: [paste code]. Identify: code duplication, overly complex functions, poor naming, violations of SOLID principles, and modernization opportunities. Prioritize by impact and risk.

This function is too long/complex: [paste function]. Identify logical chunks that could be extracted into separate functions. For each extraction, suggest: function name, parameters, return value, and how it simplifies the original.

Modernize this [old JavaScript/Python 2/etc.] code to current standards: [paste code]. Update syntax, replace deprecated patterns, use modern language features where beneficial, but preserve exact functionality. Show before/after.

This code has high cyclomatic complexity: [paste code]. Refactor to reduce nesting and branching. Consider: early returns, guard clauses, lookup tables instead of switches, and polymorphism. Maintain readability.

Suggest design pattern improvements for this code: [paste code]. Identify patterns that could help: where to apply Strategy, Factory, Observer, etc. Explain the benefit and show how the refactored code would look.

I want to refactor [describe change]. Current code: [paste]. Create a step-by-step refactoring plan where each step is independently deployable and testable. No step should break the system.
