1. 01

   Limited support for complex refactoring scenarios

   Bowler may not handle all edge cases in complex codebases, leading to manual intervention

2. 02

   Poor documentation and examples

   Official documentation lacks detailed examples and explanations for advanced use-cases

3. 03

   Active development with breaking changes

   Frequent updates introduce breaking changes, requiring significant effort to maintain compatibility

4. 04

   Narrow focus on Python limits broader application

   Tool is specifically designed for Python and does not support other languages, limiting its utility in polyglot environments

What it does well

• Automated refactoring of Python code
