    - Capture and analyze the complete output, noting error types, locations, and severity

 2. **Context Gathering**
    - Before making fixes, examine the affected files using `git diff` to understand recent changes
    - Review surrounding code to understand the implementation context
    - Check for similar patterns in the codebase using `rg` to ensure consistency
