The function `renderShellOutput` does not handle the case when `exitCode` is not 0. This could lead to unexpected behavior if the shell command fails. Please consider adding error handling for this case. 😊

The function `renderShellOutput` does not use the `stderr` variable. If the shell command produces an error, this information will be lost. Please consider including `stderr` in the output when `exitCode` is not 0. 🙏

The function `renderShellOutput` does not have a return type. Although TypeScript can infer the return type, it's a good practice to explicitly define it for better readability and maintainability. Please consider adding a return type to this function. 👍

You are returning stdout when the exitCode is 0, but you are not using stderr in any way. If the shell command generates an error, this information will be lost. Consider including stderr in your output. 😊

In the case where the exitCode is not 0, there is no explicit return statement. This could lead to undefined behavior. Please ensure all code paths return a value. 😊

The early return when exitCode is 0 might bypass important logic in the lines following this condition. Please ensure that no necessary code is being skipped due to this early return. 🧐

$`Your are an expert software engineer and you are able to analyze the logs and find the root cause of the failure.

- GIT_DIFF contains a diff of 2 run commits
- LOG_DIFF contains a diff of 2 runs in GitHub Actions for the ${owner}/${repo} repository
- The first run is the last successful run and the second run is the first failed run

## Task 1

Analyze the diff in LOG_DIFF and provide a summary of the root cause of the failure.

If you cannot find the root cause, stop.

## Task 2

Generate updates for the source files that can fix the issue.
- use a unified diff format compatible with diff

## Task 3

Generate annotations in the source code to help identify the root cause of the failure.
