20 of the best prompts for surfacing full error stack, step by step across 4 stages. Works with ChatGPT, Claude, and Gemini.
Published June 28, 2026
Most people try to use AI for Surfacing Full Error Stack with a single vague prompt and get generic results. This guide takes a different approach: 4 targeted stages, from Diagnose the Wall through Prevent Recurrence, each with a prompt that gives the AI exactly the context it needs. Lovable is only reading the first line of an error, which can lead to missing the root cause buried in the stack trace. This results in unresolved issues and inefficient debugging. These prompts help developers ensure Lovable reads the entire error stack to identify and fix the root cause effectively. Works with ChatGPT, Claude, and Gemini.
Identify the specific error Lovable is missing by not reading the full stack trace.

Ensure that the suggestions are practical and relevant to the context of the issue at hand.
Confirm Fix Implementation
Please confirm that the recent fix has effectively addressed the root cause identified in the error stack trace. Provide a detailed analysis of the changes made and explain how they resolve the issue. Include any relevant test results or observations that demonstrate the fix's effectiveness. Additionally, outline any potential implications or further actions that may be necessary to ensure the issue does not recur.
Ensure that the error is resolved and Lovable is functioning correctly.
Run Build Verification
Please execute a new build for the project and confirm that the previous error related to [ERROR DESCRIPTION] no longer occurs. After the build is completed, provide the detailed output logs for verification. Additionally, summarize any changes made since the last build that may have contributed to resolving the issue. Ensure that the output is clear and highlights any relevant information that indicates the error has been resolved.
Check for Silent Failures
Please analyze the build process for any silent failures that may have occurred. Provide a detailed report outlining any issues detected, including the nature of the failures, their potential impact on the build, and suggestions for resolving them. Additionally, include any relevant logs or error messages that can help in diagnosing the problems. Ensure that the report is structured clearly, with sections for each identified issue and recommended next steps.
Validate Component Changes
Please verify that all approved changes made to the components in [COMPONENT NAME] are still intact following the recent fix. List each change that was implemented and confirm whether it has been retained or altered. If any changes are missing or modified, provide details on what has changed and suggest potential next steps for resolution. Format your response in a clear, structured manner to facilitate easy review.
Assess System Stability
Please evaluate the overall stability of the system following the recent fix. Provide a detailed assessment that includes any lingering issues or anomalies that may still be present. Outline the specific areas of the system that were affected by the fix, and note any performance metrics or error logs that indicate ongoing problems. Additionally, suggest any further actions that may be necessary to ensure complete stability and reliability moving forward.
Confirm Error Absence
Please verify that the specific error identified as [ERROR NAME] and its root cause, which was [ROOT CAUSE], are no longer present in the system. Provide a detailed report on the steps taken to confirm this, including any relevant logs or metrics that demonstrate the absence of the error. Additionally, outline any changes made to the system that may have contributed to resolving the issue and suggest any further monitoring or testing that should be conducted to ensure the error does not reoccur.
Create mechanisms to prevent similar issues from happening in the future.
Draft CLAUDE.md Rule
Please draft a new rule for CLAUDE.md that mandates the review of full error stacks for all resolved issues. The rule should include the rationale for its importance, the specific steps that need to be taken to ensure compliance, and any consequences for failing to adhere to this rule. Additionally, provide examples of scenarios where reviewing the full error stack would be critical for preventing future issues. Format the rule clearly with headings and bullet points for easy reference.
Add Code Comment
Please add a comment in the codebase that emphasizes the importance of reviewing full error stacks when troubleshooting issues.

Explain the benefits of this convention in terms of improving error tracking and facilitating quicker resolution of issues.
Implement Project Guard
Design a project guard that alerts developers when only the first line of an error message is being considered, ensuring that all relevant details are taken into account. The guard should analyze error logs and identify instances where additional context from the error stack is ignored. Provide a detailed outline of the implementation process, including the programming language to be used, the specific conditions that trigger the alert, and how developers will be notified. Additionally, suggest ways to enhance the guard's functionality to improve error handling and debugging efficiency in the project.
Lovable may only read the first line of an error, missing crucial information buried deeper in the stack trace. This can lead to incomplete diagnostics and unresolved issues.
Use prompts to explicitly request the full error stack trace and guide Lovable to consider all lines for a comprehensive analysis.
Verify that Lovable retains all approved changes by running checks post-fix and confirming that no reversion occurs.
Implement project guards and session-opener checklists to ensure Lovable processes error stacks fully and avoids repetitive cycles.
Always request the complete error stack, confirm fixes with build verification, and update CLAUDE.md with new rules to prevent future issues.
