To debug error propagation in an autonomous coding assistant for shared repositories by implementing dependency tracking, version-aware execution, rollback mechanisms, peer validation, and isolated test environments.
Here is the code snippet you can refer to:

In the above code we are using the following key points:
- Dependency Change Detection: Flags updates in requirements.txt or package.json.
- Isolated Test Execution: Runs tests separately to prevent cross-impact issues.
- Error-Based Rollback Suggestion: Provides commit-level rollback options.
- CI/CD Integration Compatibility: Can be integrated into GitHub Actions or GitLab CI.
- Pre-Merge Validation: Prevents broken changes from propagating across the repository.
Hence, debugging error propagation in an autonomous coding assistant for shared repositories requires dependency tracking, rollback mechanisms, isolated testing, and structured validation to prevent breaking changes from affecting collaborative development.
