Lock headline and primary-text caps
Write a Snapchat Ads catalog copy pack from SKU facts. Honor character caps. No invented CTR or reviews. Start by filling Inputs, not by asking the model to remember last week's run. If a field is blank, write NONE or NOT IN INPUTS and leave it blank through Generate. The card is built so the model cannot honestly invent a number, owner, URL, or command that you did not paste.
Paste these fields before you hit run:
SKU facts I lock (name, material, size, pack): [Facts]
Headline character cap I lock: [HeadCap]
Primary-text character cap I lock: [BodyCap]
Words I must not use: [Banned]
What I must never invent (CTR, ROAS, reviews, prices): [Never]
Output format: [Format]
Language: [Lang]
CTA I allow (or UNKNOWN): [Cta]
Brand I may name (or UNKNOWN): [Brand]
That inventory is the honesty ledger. Anything that does not appear there is forbidden in the draft. If you catch yourself adding a nice-to-have after the run, you are no longer using the card. You are ghostwriting. Put the extra fact in Inputs and run again.
Write copy only from SKU facts
Generate is numbered on purpose. Do not skip a step because the first paragraph looked done. The early steps exist to stop later prose from smuggling claims.
Walk the Generate list in order:
- Honesty ledger: Facts nouns, HeadCap, BodyCap, Cta, Brand, Lang. Forbidden: invented CTR, ROAS, reviews, prices.
- Cap table: headline length vs HeadCap. primary text length vs BodyCap. Print counts.
- Headline: Facts only. Brand only if Brand is not UNKNOWN. No review language.
- Primary text plus CTA: only attributes in Facts. Extra claims write NOT IN INPUTS. CTA from Cta or CTA UNKNOWN.
- Refuse list: Meta Advantage+ catalog, Nextdoor neighbor counts, TikTok caption, CTR percents, star integers.
- Brand: quote Brand or write BRAND UNKNOWN.
- Never: do not write 3.1 percent CTR. Do not invent a $12.99 price. Do not invent 4.8 stars.
- Compliance pass: quote Banned and Never hits. Cut them. Print character counts. Format as Format.
If a step asks for a version lock, quote the version from Inputs in the output. If a step asks for a refuse list, keep the refuse list in the published artifact, not in a sidebar you delete. Reviewers should see what the model was not allowed to do.
Refuse CTR ROAS and star ratings
Most failures are the same shape: a missing field gets a confident fill. A conversion rate appears. A Gradle task appears. A flash point appears. A caption appears on a job that asked for slide text only. Your review is to search the draft for numbers, names, and commands, then grep Inputs. No match means cut.
Honor the constraints as hard stops, not vibes:
- Snapchat Ads catalog copy from Facts only. Not Meta Advantage+ and not captions.
- Never invent CTR, ROAS, reviews, or prices.
- Honor HeadCap and BodyCap as hard caps.
- No emojis.
When the card says not legal advice, not certification, not an exam dump, or not a caption engine, that sentence belongs at the top of the output. Deleting it to look more finished is how you inherit risk.
Print character counts against the caps
Finish with the compliance pass the prompt already asks for. Quote the banned-word hits. Cut them. Print character counts when the job has a cap. Print word counts when the job has a budget. List gaps as gaps. Five missing facts are more useful than one smooth paragraph.
Tags on the card (snapchat ads catalog copy, character caps sku facts, no invented ctr) are a reminder of the job shape, not an invitation to wander into a neighboring cluster. If you need a different surface, open a different PromptDig card rather than stretching this one.
Fill the card, then run
Replace every bracket. Run on ChatGPT, Claude, or Gemini. Read the ledger first, then the artifact. If the model invents a commit, KPI, DOI, PEL, bid, or logo, discard the run. Tighten Inputs. Run again. Share the filled card that survived, not the first draft that sounded done.
