Getting Detect Function Signature Changes right takes more than a single prompt. This 4-stage guide covers Diagnose the Wall, Isolate and Fix, Verify the Resolution, and more, breaking the whole process into focused steps where each prompt builds on the last. When Bolt changes a function signature without updating all calling files, it leads to runtime errors that can block development. If left unaddressed, these errors can cascade into larger issues, causing significant delays. By following this guide, developers can ensure that function signatures remain consistent across their applications. Every prompt is optimized and runs in ChatGPT, Claude, and Gemini.

Additionally, suggest potential solutions or adjustments that could be made to rectify the issue.

Diagnose the Wall

Isolate and Fix

Target the specific function signature that has changed and needs to be reverted or updated. Focus on ensuring all references are consistent.

Revert Function Signature

Please revert the function signature at [FILE]:[LINE] to its original form. The original signature is: [PASTE]. The modified signature is: [PASTE]. Before applying the change, provide a diff that highlights the differences between the original and modified signatures.

Isolate and Fix

Rewrite with Explicit Constraint

Rewrite the function located at [FILE] on line [LINE] to ensure it strictly adheres to the expected signature: [EXPECTED SIGNATURE]. Additionally, verify that all references to this function throughout the codebase are updated accordingly to reflect the new signature. Provide a summary of the changes made and any potential impacts on the surrounding code.

Isolate and Fix

Scoped Change to Function Calls

Please update all calls to the function located at [FILE]:[LINE] to ensure they match the expected signature of [EXPECTED SIGNATURE]. Focus on modifying only the relevant files to maintain consistency across the codebase. After making the changes, provide a summary of the modifications made and any potential impacts on related functions.

Isolate and Fix

Enforce Signature Format

Check the function signature at [FILE] on line [LINE] against the expected format of [EXPECTED FORMAT]. If the signature does not conform to this format, please correct it and provide the updated code snippet. Additionally, include a brief explanation of the changes made to ensure clarity on how the signature was adjusted.

Isolate and Fix

Correct Import Dependencies

Verify that all import statements in the file located at [FILE] on line [LINE] correctly reference the updated function signature. If you find any outdated imports, please update them to align with the expected signature. Additionally, provide a brief summary of the changes made and any potential impact these corrections may have on the overall functionality of the code.

Isolate and Fix

Verify the Resolution

Confirm that the function signature issue has been resolved by checking for errors in the console. Look for successful execution of all function calls.

Run a Test for Function Calls

Please run the test suite for the function calls located at [FILE]:[LINE]. Ensure that all tests pass successfully and verify that there are no signature-related errors. Provide a summary of the test results, including any errors encountered and suggestions for resolving them if applicable.

Verify the Resolution

Show the Diff of Changes

Please provide a detailed comparison of the changes made to the function located at [FILE]:[LINE]. Highlight the differences in the code, confirm that the function signature aligns with the expected format, and ensure that all references to this function throughout the codebase have been updated accordingly. Present the findings in a structured format, including a summary of the changes and any potential impacts on the overall functionality.

Verify the Resolution

Replay Original Failing Scenario

Replay the original scenario that resulted in the function signature error for the [API NAME]. Provide a detailed account of the steps taken to reproduce the issue, including any relevant input data and configurations. After replaying the scenario, confirm whether the error persists and describe the application's behavior, noting any changes or improvements observed in its functionality.

Verify the Resolution

Check Edge Cases for Regression

Identify and test edge cases related to the function at [FILE]:[LINE]. Please provide a detailed report on each edge case, including the expected behavior, the actual behavior observed during testing, and any discrepancies found. Additionally, suggest any necessary changes to ensure that all edge cases are handled correctly without introducing new signature issues. Format the report with clear headings for each edge case tested.

Prevent Recurrence

Implement artefacts that prevent future issues with function signature changes. Focus on maintaining consistency across the codebase.

Function Signature Consistency Check

Draft a session-opening constraint for the project titled 'Function Signature Consistency Check.' Use the following structure: 'Before any function signature change, verify that all calling files are updated accordingly. If [TRIGGER] occurs, stop and [ACTION] before continuing. Never deploy without confirming signature consistency.' Ensure that the constraint is clear and actionable, providing specific examples of potential triggers and actions that should be taken.

Prevent Recurrence

Function Call Validation Template

Please create a validation template for function calls that includes the following instructions: For every function signature change, ensure that all instances in [SPECIFIC FILES] are updated accordingly. If any outdated instances are found, list them clearly and request confirmation from the user before proceeding with any further actions. Format the output as a checklist that can be easily followed.

Frequently asked questions

What happens if I change a function signature?+

Changing a function signature without updating all references can lead to runtime errors in Bolt. This is because the tool may not automatically propagate changes to all calling files, resulting in broken functionality.

How can I identify where a function signature is used?+

You can use the search functionality in Bolt to find all instances of a function signature. This helps ensure that any changes made are reflected in all relevant parts of the codebase.

What should I do if I encounter a signature mismatch error?+

If you encounter a signature mismatch error, check the console for the exact error message. This will help you identify which function calls are failing and require updates to align with the new signature.

Can Bolt automatically update function calls?+

Bolt does not automatically update function calls when a signature changes. Developers must manually ensure that all references are consistent to avoid runtime errors.

How can I prevent signature change issues in the future?+

To prevent signature change issues, implement a verification process that checks all function signatures before deployment. This can include automated tests that confirm all references are updated accordingly.
