# Code Review Comments for PR #2890 - Add Crew Name Attribute to `CrewBase`

## Overview
This pull request introduces a `_crew_name` attribute to `CrewBase` annotated classes, designed to store the original class name. This enhancement provides useful introspection capabilities during debugging. The changes impact two files: `src/crewai/project/crew_base.py` and `tests/project_test.py`.

## File Analysis

### 1. `src/crewai/project/crew_base.py`

#### Changes Review
- **New Line Added**: `WrappedClass._crew_name = cls.__name__`
- This addition effectively stores the original class name in a protected attribute, facilitating introspection.

#### Issues & Recommendations
1. **Documentation Missing**:
   - **Current**: 
     ```python
     WrappedClass._crew_name = cls.__name__
     ```
   - **Recommendation**: Add a comment for clarity.
     ```python
     # Store the original crew class name for introspection and debugging
     WrappedClass._crew_name = cls.__name__
     ```

2. **Type Hints Missing**:
   - **Current**: No type hint.
   - **Recommendation**: Incorporate type hinting.
     ```python
     WrappedClass._crew_name: str = cls.__name__
     ```

3. **Consider Adding Property Access**:
   - **Recommendation**: Create a read-only property.
     ```python
     @property
     def crew_name(self) -> str:
         """Returns the original crew class name."""
         return self._crew_name
     ```

### 2. `tests/project_test.py`

#### Changes Review
- A new test case `test_crew_name()` was added to verify the `_crew_name` attribute.

#### Issues & Recommendations
1. **Test Documentation**:
   - **Current**:
     ```python
     def test_crew_name():
         crew = InternalCrew()
         assert crew._crew_name == "InternalCrew"
     ```
   - **Recommendation**: Add docstrings for clarity.
     ```python
     def test_crew_name():
         """
         Test that CrewBase classes correctly store their original class name
         in the _crew_name attribute.
         """
         crew = InternalCrew()
         assert crew._crew_name == "InternalCrew"
     ```

2. **Test Coverage**:
   - **Recommendation**: Add tests for inheritance and immutability.
     ```python
     def test_crew_name_inheritance():
         """Test crew name behavior with inheritance."""
         class BaseCrew(CrewBase):
             pass

         class DerivedCrew(BaseCrew):
             pass

         crew = DerivedCrew()
         assert crew._crew_name == "DerivedCrew"

     def test_crew_name_immutability():
         """Ensure that crew name cannot be modified after initialization."""
         crew = InternalCrew()
         with pytest.raises(AttributeError):
             crew._crew_name = "NewName"
     ```

## General Recommendations
1. **Documentation**: Enhance both function and attribute documentation across the codebase.
2. **API Design**: Consider making `_crew_name` public or protecting it effectively through property methods.
3. **Type Safety**: Add type hints consistently for better clarity and maintainability.

## Impact Analysis
Overall, the changes carry low risk and are backward compatible, enhancing the readability and maintainability of the code. The new functionality will aid in debugging efforts without imposing significant performance overhead.

## Conclusion
The changes made are valuable, but further refinement through documentation, expanded test coverage, and type safety improvements will strengthen the overall quality of the code. Implementing these recommendations will lead to better maintainability and robustness in the project's architecture.
