Async functions in Windsurf often fail to catch, handle, or propagate errors correctly, leading to unpredictable application behavior. This can result in silent failures or crashes that are difficult to debug. These prompts help developers ensure robust error handling in async functions, improving application stability. 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.

Additionally, include examples of potential error scenarios and how your refactoring mitigates them.

Isolate and Fix

Verify the Resolution

Ensure that the async error handling issues are resolved and the code behaves as expected.

Run Error Handling Tests

Please execute a series of tests on the following function: [PASTE FUNCTION]. Focus on verifying that all potential errors are handled correctly, including both synchronous and asynchronous scenarios. For each test case, document the expected outcome versus the actual outcome, and provide a summary of any errors that were caught or missed during the tests. Additionally, include recommendations for any further improvements to error handling based on your findings.

Verify the Resolution

Simulate Error Scenarios

Please simulate potential error scenarios in the following code: [PASTE CODE]. Identify and describe at least three different types of errors that could occur during execution. For each error scenario, explain how the existing error handling mechanisms respond and whether they effectively manage the error. Additionally, provide suggestions for improving error handling if necessary, and summarize the overall robustness of the error management in the code.
