Turn client wins into formatted case studies for proposals, social proof, and sales conversations. Use when someone needs to document results, build credibility, or create reusable proof assets.
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 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. --- ## Mode 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. --- ## Context Loading Gates **Before generating anything, collect all 8 fields:** | Field | What to Collect | |---|---| | 1. Client | Industry, company size/stage, named or anonymized? | …

How to install
mdr add brianrwagner/ai-marketing-claude-code-skills/case-study-builder@sha256:680dba23ce33f81cThe line at the top of this page pins the label git:20260308.1c3e1fe, 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.
