Create customer case studies in sales-ready format — Challenge→Solution→Results structure, before/after metrics, quote integration, two-length formats (1-page summary + full version). Use when creating case studies, customer success stories, proof content, or sales collateral. Triggers on: "case study", "customer story", "success story", "proof content", "customer example", "results story", or any request to document customer outcomes.
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 Builder ## Overview A case study is the most versatile proof asset in B2B. It proves your product works in someone else's hands. This skill produces sales-ready case studies: one-page for quick sharing, full version for late-stage deals, always with specific metrics and real quotes. The golden rule: a case study without numbers is a testimonial. Every case study must answer "what changed, and by how much?" ## Authoritative Foundations - **Before-After-Bridge copy formula** — Structure the story as the customer's situation before, the result after, and the product as the bridge between them. - **Joanna Wiebe (Copyhackers) — Voice-of-customer copy** — Quote the customer's own words for the problem and result; interview transcripts beat marketing paraphrase. - **Nielsen Norman Group — How users read on the web** — Readers scan in an F-pattern, so lead with the metric, use subheads, and keep proof in the first screen. ## When to Use - "Create a case study about [customer]" - "Write a customer success story" - "Build proof content for sales" - "Document customer results" - "Create a case study for our website" - "I need customer proof for a deal" …

How to install
mdr add leadmagic/gtm-skills/case-study-builder@sha256:87bac048ed3339f6The line at the top of this page pins the label v1.1.0, 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.
