If len(additional_search_paths) >= 5, an error would be raised: Priority must be positive, got 0

because of the code below:

skillkit/core/manager.py

PRIORITY_CUSTOM_BASE = 5

sources.append(
    SkillSource(
        source_type=SourceType.CUSTOM,
        directory=custom_path.resolve(),
        priority=PRIORITY_CUSTOM_BASE - i,  # Decrement for each additional path
    )
)
