Overengineering can lead to unnecessary complexity in your application, making it harder to maintain and understand. If left unresolved, this can result in increased development time and potential bugs. By following this guide, you will streamline your code, making it simpler and more efficient to work with. Built across 4 distinct stages covering Diagnose the Wall, Isolate and Fix, Verify the Resolution and more, this guide gives you one expert prompt per step so you never have to write from scratch or guess what the AI needs. The prompts work in ChatGPT, Claude, and Gemini and are designed to get usable output on the first try.

Diagnose the Wall

Look for instances where the AI has added unnecessary abstraction layers or design patterns in your code. Check the specific function or component that seems overly complex.

Quote the Unnecessary Abstraction

Please quote the exact output generated by the function 'calculateTax' in the file 'taxCalculator.js'. Then, compare this output to the original requirement, which was to perform a straightforward tax calculation without any unnecessary abstractions. Highlight any discrepancies you find between the output and the original requirement, and provide a brief explanation of how the additional layers affect the functionality.

Diagnose the Wall

Paste and Analyze Function

Please paste the 'calculateTax' function from 'taxCalculator.js' below. Analyze the function for any modifications made to it, and identify any unnecessary design patterns or abstractions that have been introduced. Provide a detailed explanation of how these changes impact the function's performance and readability, and suggest improvements to simplify the design.

Diagnose the Wall

Interpret Original Instruction

Please explain your interpretation of the original instruction to create a simple tax calculation function. In your response, clarify any misunderstandings that may have contributed to overengineering this function. Additionally, provide a concise summary of the key elements that should be included in a straightforward implementation of the tax calculation, ensuring that it remains efficient and focused on the core requirements.

Diagnose the Wall

Expected vs. Actual Behavior

List the expected behavior of the 'calculateTax' function, which should return a simple numeric value based on the input provided. Then, compare this expected behavior to the actual output generated by the AI. Highlight any added complexity or discrepancies in the output, and provide a brief explanation of how the actual output deviates from the expected behavior. Format your response in a clear comparison table with columns for 'Expected Behavior', 'Actual Output', and 'Notes on Complexity'.

Diagnose the Wall

Identify Violated Constraints

Identify the specific rule or constraint that was violated in the implementation of the 'calculateTax' function. Please quote the exact clause from the design guidelines that states the requirement for simplicity in function design. Additionally, provide an explanation of how this violation impacts the overall code quality and suggest a revised version of the function that adheres to the simplicity requirement.

Diagnose the Wall

Isolate and Fix

Target the specific function or component that has been overengineered. Focus on simplifying its structure and removing unnecessary abstractions.

Inline Fix for Function Signature

Revert the 'calculateTax' function in 'taxCalculator.js' to its original signature: 'function calculateTax(income)'. Ensure that any additional parameters that were added unnecessarily are completely removed. After making these changes, provide a brief explanation of the impact of this modification on the function's usability and performance.

Isolate and Fix

Rewrite with Explicit Simplicity Constraint

Rewrite the 'calculateTax' function in 'taxCalculator.js' to ensure it performs a direct calculation without any additional abstractions or design patterns. The function should take in parameters for income and tax rate, and return the calculated tax amount. Please provide the updated code along with a brief explanation of how it meets the simplicity constraint.

Isolate and Fix

Scoped Change to Remove Layers

Please modify the 'calculateTax' function in the 'taxCalculator.js' file. Your task is to eliminate any nested functions or classes that have been introduced, ensuring that the implementation remains straightforward and focused solely on the core tax calculation. Provide the revised code along with a brief explanation of the changes made and how they simplify the function.

Isolate and Fix

Enforce Function Format

Please review the 'calculateTax' function in the 'taxCalculator.js' file. Ensure it adheres to the following format: 'function calculateTax(income) { return income * 0.2; }'. If there is any additional code present that does not conform to this structure, remove it and provide a revised version of the function that meets the specified format.

Isolate and Fix

Correct Unnecessary Imports

Review the imports in the file 'taxCalculator.js' and identify any libraries or modules that are not necessary for the tax calculation functionality. Provide a list of the unnecessary imports along with a brief explanation of why each one can be removed. Finally, suggest an updated version of the file with only the essential imports retained.

Isolate and Fix

Verify the Resolution

Confirm that the changes made have simplified the function and that it now performs as expected. Check the output of the function.

Run a Test for Simplified Function

Please run a test for the 'calculateTax' function located in 'taxCalculator.js'. Use an input value of 1000 and verify that the output equals 200. If the output is correct, provide a brief explanation of how this confirms that the function has been simplified and is functioning as intended.

Verify the Resolution

Show Diff of Changes Made

Please provide a detailed comparison of the changes made to the file 'taxCalculator.js'. Highlight the specific lines where unnecessary abstractions have been removed and explain how the updated function aligns with the original requirements. Additionally, include a summary of the overall impact of these changes on the function's performance and readability.

Verify the Resolution

Replay Original Failing Scenario

Replay the original scenario where the 'calculateTax' function failed due to complexity. Verify that the function now executes correctly without any errors. Provide a detailed explanation of the changes made to resolve the issue and include any relevant test cases that demonstrate the function's correct behavior.

Verify the Resolution

Check Edge Case for Simplicity

Please test the 'calculateTax' function using an edge case input of 0. Confirm that the output is 0, and provide a brief explanation of how this demonstrates the function's ability to handle edge cases simply and effectively. Additionally, include any relevant details about the expected behavior of the function in this scenario.

Verify the Resolution

Confirm Function Output State

Verify the output of the 'calculateTax' function in 'taxCalculator.js'. Confirm that the output is a simple numeric value and does not produce any complex objects or structures. Provide a brief explanation of how you validated this and include any relevant test cases or examples that demonstrate the expected output.

Verify the Resolution

Prevent Recurrence

Create artefacts that will prevent the recurrence of overengineering in future development. Focus on guidelines and constraints.

Simplicity Enforcement Instruction

Before implementing any function, please verify that it adheres to the principle of simplicity. If you identify any unnecessary abstractions, provide a simplified version of the function and explain how it aligns with the simplicity principle. Ensure that the final implementation is straightforward and easy to understand.

Prevent Recurrence

Design Pattern Constraint Message

Draft a project convention message that clearly states: 'All functions must be designed to perform a single task without introducing additional design patterns.' Include a brief explanation of the importance of this guideline and instruct team members to review each function for adherence to this principle before finalizing their work. Format the message in a way that it can be easily shared with the team, ensuring clarity and emphasis on the key points.

Prevent Recurrence

Code Comment Guard for Simplicity

Please add a comment guard in the 'taxCalculator.js' file. The comment should read: '// Ensure this function remains simple and direct. Any future changes must not introduce additional complexity or abstractions.'
