Write customer case studies and success stories using the Situation-Complication-Resolution (SCR) narrative framework and Barbara Minto's Pyramid Principle (conclusion first). Produces case studies where the headline states the result, the complication makes readers recognize their own situation, and every paragraph advances the story. Use when the user asks for a case study, customer story, customer success story, win story, reference write-up, or "turn this customer into a case study". Reads…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# case-study-writer

Turns raw customer interview material into a structured case study. Mandatory SCR (Situation-Complication-Resolution) narrative structure with Pyramid Principle headline. Designed for sales enablement and SEO. The reader is a busy prospect who will decide in 10 seconds whether to keep reading - the conclusion goes first, not last.

## When to use

- "Write a case study from these notes"
- "Turn this customer interview into a story"
- "Draft a customer success story for X"
- "We need a reference write-up"

## Framework: SCR + Pyramid Principle (McKinsey storytelling / Barbara Minto)

**Why SCR, not chronological storytelling:**
Chronological case studies bury the hook. Readers are busy. SCR gets to the problem in the first paragraph, which is where readers decide whether this is relevant to them.

**The 3 SCR components:**

| Component | Length | What it must do | It has failed when |
|---|---|---|---|
| **Situation** | 1 paragraph | State only what the reader accepts without argument | It reads as a company profile, or the reader has to be persuaded of anything in it |

How to install

The exact contents, by fingerprint
mdr add qa-aman/claude-skills/case-study-writer@sha256:0ac02ed1e623ef54

The line at the top of this page pins the label git:20260808.7dfb5c7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
