-### Testing
-- **Run all tests**: `fish -c "mamba activate acq4-torch; python -m pytest"`
-- **Run specific test file**: `fish -c "mamba activate acq4-torch; python -m pytest coorx/tests/test_transforms.py"`
-- **Run single test**: `fish -c "mamba activate acq4-torch; python -m pytest coorx/tests/test_transforms.py::CompositeTransform::test_as_affine"`
-- **Collect tests only**: `fish -c "mamba activate acq4-torch; python -m pytest --collect-only"`
+All commands likely require running python from a particular environment. If this is not specified in an agent instruction file, then prompt the user.
 
-### Environment
-- **Activate environment**: Always use `fish -c "mamba activate acq4-torch; <command>"` since mamba is not available in bash
-- **Install package in development mode**: `fish -c "mamba activate acq4-torch; pip install -e ."`

 ### Image Support (`image.py`)
 - Image class that tracks coordinate system of pixel data
 - Integrates with transform system for spatial transformations
+- Basic manipulations like crop, scale, and rotate track transformations to allow mapping between pixels of original and final images
 
 ### Testing Infrastructure
 - Custom pytest plugin (`conftest.py`) for Jupyter notebook testing
 - Pristine state checking and execution comparison for `.ipynb` files
