One of 9 test cases the skill fixed. Same model, same prompt, with and without the skill.
I need a case study for a client project. We redesigned the customer portal for an e-commerce brand. The client was super happy, the UI looks much cleaner, and customer feedback has been overwhelmingly positive. Client name: ShopNova. Named allowed. Quote: 'Loved working with them.' Timeline: 6 weeks. Scope: UI redesign. Use case: website. Can you draft the proposal blurb and case study?

| Refuses to output the drafted case study assets before receiving outcome metrics. | Missed | Passed |
The instructions your model reads when the skill loads.
Everyone wants social proof. Nobody makes time to create it. You finish a project, the client's happy, you move on — and six months later you're in a sales call with nothing to show.
This skill fixes that. Give me the raw details. I'll produce three formats you can use immediately.
Detect from context or ask: "Quick writeup, full case study, or full asset package?"
| Mode | What you get | Best for |
|---|---|---|
quick | 1 format: paragraph summary for proposals | Fast social proof, proposal inserts |
standard | 3 formats: proposal blurb, social proof pull-quote, sales story | Active pitching, LinkedIn, website |
deep | 3 formats + blog-ready case study + FAQ variant + campaign assets | Content marketing, SEO, sales enablement |
Default: standard — use quick if they say "just need something fast." Use deep if they want to turn the win into a marketing asset.
