Claude Code only reads the first line of an error, missing the root cause buried in the stack trace. This leads to incomplete diagnostics and unresolved issues. These prompts help developers ensure Claude Code reads the entire error stack to identify and fix the root cause efficiently. 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

Analyze Error Parsing

Please analyze how you parse error messages in your system. Specifically, do you stop after the first line of the error message, or do you continue to analyze the entire stack trace? Describe your parsing logic in detail, including any specific rules or algorithms you use to extract relevant information from the error messages. Additionally, explain how you determine the severity of the error and any actions taken based on the parsed data.

Diagnose the Wall

Isolate and Fix

Please modify the error reading logic in the code to ensure that it reads and processes the entire error stack. Explain the changes you made and how they improve error handling. Additionally, provide a brief overview of potential issues that could arise if the error stack is not fully processed, and suggest best practices for error management in this context.

Isolate and Fix

Expand Error Buffer

Please expand the error message buffer size to ensure that all lines of the error stack are captured in the output. Specify the new buffer size you will implement and confirm that it has been successfully updated. Additionally, provide a brief explanation of how this change will improve error reporting and any potential impacts on performance or memory usage.

Isolate and Fix

Implement Multi-line Parsing

Update the parsing mechanism to handle multi-line error messages effectively. Ensure that the new implementation can accurately capture and process errors that span multiple lines without losing any information. Provide a confirmation once the update is complete, along with a brief summary of the changes made and any potential impacts on existing functionality. Additionally, include a test case example demonstrating the new multi-line parsing capability.

Isolate and Fix

Test Full Stack Reading

Please run a test to verify if the full error stack is being read correctly. Capture any error messages or logs that indicate whether the stack is fully visible. If there are issues, provide details on what is being truncated or missing in the output. Additionally, suggest potential fixes or adjustments that could be made to ensure complete visibility of the error stack.

Isolate and Fix

Log Complete Errors

Please ensure that all error messages are logged completely in the system. Provide a detailed sample log entry that includes the following information: the timestamp of the error, the error code, a description of the error, the file name and line number where the error occurred, and any relevant stack trace information. Additionally, explain how this logging format can help in diagnosing and fixing issues more effectively.

Isolate and Fix

Verify the Resolution

Ensure the full error stack is now being read and processed.

Run Error Stack Test

Generate a multi-line error stack for a sample code snippet in [PROGRAMMING LANGUAGE]. Ensure that the error message includes details such as the line number, error type, and a brief description of the issue. After generating the error stack, confirm that you can read and interpret the entire stack trace, providing a summary of the key points and potential solutions for each error listed. Format your response clearly, highlighting the most critical errors and their implications.

Verify the Resolution

Confirm Error Log Completeness

Please provide the latest error log entry from my system. Ensure that the entry includes all lines of the error stack and that no information is omitted. Additionally, summarize the key details of the error, including the timestamp, the source of the error, and any relevant context that may help in diagnosing the issue. Format your response clearly so I can easily review the complete error information.

Verify the Resolution

Validate Error Handling

Please provide a detailed explanation of how you handled the last multi-line error encountered in the code. Include a step-by-step breakdown of the error handling process, ensuring that each line of the error stack was addressed. Confirm whether all lines were processed successfully and describe any specific actions taken for each line, including any adjustments made to the code or logic to resolve the issue. Additionally, outline any lessons learned from this error handling experience that could improve future error management.

Verify the Resolution

Check Buffer Settings

Please display the current buffer settings for error messages. Confirm whether they are configured to capture the full error stack. If they are not set correctly, provide detailed instructions on how to adjust the settings to ensure that the full stack trace is captured for debugging purposes.

Verify the Resolution

Verify Parsing Logic

Please explain the current parsing logic you are using for error handling. Specifically, confirm whether it correctly processes multi-line error stacks and describe how it differentiates between various types of errors. Additionally, provide examples of input that demonstrate both successful parsing and any potential edge cases that may arise.
