# Parallel branch bug fixing and test repair

Diagnose failing automated checks across isolated worktrees and prepare verified patches for review

[Use with BotBento ](https://app.botbento.com/?ref=usecases&utm_source=botbento.com&utm_medium=usecases&utm_campaign=parallel-branch-bug-fixing-and-test-repair)Copy promptShare[Markdown](/text/usecases/parallel-branch-bug-fixing-and-test-repair/index.md)[العربية](/ar/usecases/parallel-branch-bug-fixing-and-test-repair/)

Opens BotBento. Paste the prompt into a bot; nothing is preconfigured.

- When something happensFailed check detected
- ThenDebug and verify locally
- ResultSubmit patch for approval

Inspect failed continuous integration runs and developer task prompts, isolate changes within dedicated branches or worktrees, reproduce failing tests in the command line, and draft precise code repairs. The bot reports test results and code diffs back for developer inspection before committing or opening pull requests.

## Prompt to start with

BotBentoRecommended

```
When assigned an issue or failing build, check out a fresh task branch to avoid interfering with active work. Review the build failure logs, locate the offending code and unit tests, and replicate the failure locally in the terminal. Formulate a minimal code fix and run test suites to verify resolution. Never commit, push to remote branches, open pull requests, or delete branches without explicit human approval. Present a summary of modified hunks and test outcomes for sign-off.
