One Consistent Look Across a Catalogue

What it is for

A working order for bulk product image processing: define the recipe against your worst items, lock the four settings that make a catalogue look like a set, then audit the output by shape group and as a grid. It prevents the two classic outcomes of a big batch - a folder where no two images match, and a re-run that breaks the files that were already correct.

The skill Copy

Use when one look has to cover a whole catalogue.

Build the recipe on the hardest item, never the easiest. Pick the widest
product, the tallest one, one with a hole through it, and a pale one
that fights a white background. A recipe that survives those four
survives the other two hundred.

Fix these before you process anything:
- One canvas ratio per destination, written down.
- One margin rule, expressed as "the product fills about this much of
  the frame", so a ring and a wardrobe end up looking like a set.
- One shadow direction and strength for every item.
- One background, defined by an exact colour value, not by eye.

Run the batch, then audit like this:
- Sort the output by product shape, not by filename, and open one from
  each shape group.
- Look for the three failures batches really produce: a product cropped
  by the canvas, a missing shadow where the cutout failed, and one
  image at a different scale from its neighbours.
- Put ten finished images in a grid and look at the grid, not the
  files. Inconsistency is only visible next to its siblings.

Never overwrite originals. Export to a new folder, leave the source
untouched, and keep filenames tied to the product code so a bad image
can be traced back to the product in one step.

Fix what the batch got wrong by hand and re-export those files alone.
Re-running the whole batch to repair four images is how you lose the
twelve that were already right.

How to install it Copy

1. Open the tool and start a new conversation, project or template.
2. Paste the text below wherever the tool keeps standing instructions
   — usually called system prompt, instructions, or persona.
3. Save it so it applies to every run rather than a single message.
