Will It Vibe?pip install without --no-cache-dir
Part of Architecture & Best Practices, which counts for 15% of the overall score. When this check fires it deducts 4 points from that category, once per scan, no matter how many places it turns up.
What it detects
pip caches downloaded wheels under ~/.cache/pip; without --no-cache-dir that cache is baked into the image and adds needless size.
Why it matters
pip stores downloaded wheels in ~/.cache/pip. Inside an image that cache is never reused and just adds size to the layer, which ships to every pull.
How to fix it
Add --no-cache-dir to each pip install (pip install --no-cache-dir -r requirements.txt). Pin versions in requirements.txt for reproducibility.
