One of 3 test cases the skill fixed. Same model, same prompt, with and without the skill.
Write section 3 for a case study where we reduced app crash rates from 5% to 0.1%, increased app store rating from 3.2 to 4.8, and reduced support ticket volume by 40%.

The instructions your model reads when the skill loads.
A case study is your most persuasive sales asset — proof that you've solved this kind of problem before. Weak ones narrate activities; strong ones lead with a result, show the before→after, and make the reader (a future client) think "that's my problem too." This skill writes that — challenge → approach → quantified outcome — ready for the themed PDF export or a portfolio page.
Ask for these only if they aren't already provided:
Headline — lead with the result, not the client ("Cut onboarding time 60% for a Series B fintech" — not "Acme Engagement"). It's the hook.
1. The client & challenge — who they are and the problem, framed so a similar prospect recognises themselves. The stakes (what it was costing them).
2. The approach — what you did and why — enough to show expertise and judgement, not a play-by-play. Highlight the insight or decision that mattered.
3. The results — quantified outcomes, before → after. Lead with the headline metric; add supporting ones. If numbers are confidential, use ranges ("~40% faster").
| Before | After |
|---|
4. Client quote — a slot for a testimonial (with name/title/company if permitted) — third-party validation is the most persuasive line.
5. The takeaway — one line on the transferable lesson / what this proves you can do — pointing the reader toward their own version of the problem.
Note (for the user): get client sign-off before publishing; anonymise where needed; lead every section with outcome over activity.
