Product Descriptions That Don't Invent Specs
Feed it only the specs that decide the purchase, keep one fixed skeleton across the catalog, and check the four invented facts that come back as returns.
What it is for
Catalog copy generated from a product name instead of real attributes invents compatibility, materials and warranties — and those inventions arrive back as returns. This fixes what goes in (only the four to six specs that decide the purchase, compact enough for a short input field), the output shape (one skeleton for the whole catalog), and the four-item check before publishing. Use it when writing more than a handful of product pages.
The skill
Do not paste a whole spec sheet. Give it only the four to six attributes that
decide the purchase, as compact pairs — "material: anodised alu; fits: 35mm bar;
weight: 240g; warranty: 2yr" — and add the remaining specs by hand after
generation. Fewer facts in means fewer invented facts to hunt afterwards.
The model may reorder those attributes and phrase them well. It may not add one.
Write the first three descriptions by hand. They are your skeleton — two
hundred SKUs written against a skeleton read like one shop; two hundred written
freely read like two hundred shops.
Fix the skeleton and reuse it across the catalog:
line 1 what it is, and who it is for
line 2 the one attribute that decides the purchase
line 3-4 the remaining specs, in the same order every time — this is where
the specs you kept out of the prompt go back in
line 5 what it does not do, or what it does not fit
If the catalog ships in more than one language, check the numbers survived the
switch. Decimal separators, units and sizes are where a translated catalog
quietly breaks.
Before anything goes live, hunt the four inventions that come back as returns
and chargebacks:
- compatibility it was never told about ("fits all standard mounts")
- certifications and standards nobody verified
- materials upgraded in translation: coated becomes solid, alloy becomes steel
- country of origin, warranty length, or a delivery promise you never made
Ban superlatives you cannot defend — best, leading, unmatched. In several
markets that is a legal exposure, not a style preference.
Finally, run a duplicate check across the catalog. Generated copy for similar
SKUs converges on the same sentences, and search engines treat a catalog of
near-identical text exactly as it deserves.
How to install it
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.
