## What it does

The skill walks a story from qualification to finished draft. First it checks whether the story is worth writing at all: if the subject is your own system or your own project's progress, it points you to other skills from the same author. Then comes an interview with the case-study owner, a reconstruction of the timeline from tickets, issues and PRs, and a draft against a fixed outline.

Inside are the step-by-step workflow and reference files: a source-interview guide, the case-study outline, and rules for approval and anonymization. One step builds an evidence ledger, where every claim in the study gets a row naming the instrument behind it and who can re-derive it. The limitations section is mandatory and cannot be skipped.

Approval for names, quotes and metrics runs in parallel with drafting, so find out early who on the customer side grants it and how long that takes. If their legal review outlasts your publication date, the story will not make it — that is a reason to pick another candidate or step down the anonymization ladder before you write.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add samber/developer-relations-skills --skill developer-case-study -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/developer-case-study/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/developer-case-study/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add samber/developer-relations-skills --skill developer-case-study -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/developer-case-study/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add samber/developer-relations-skills --skill developer-case-study -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/developer-case-study/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install samber/developer-relations-skills developer-case-study
```

2. **Manually: put the files in place**
- File: `.github/skills/developer-case-study/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add samber/developer-relations-skills --skill developer-case-study -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/samber/developer-relations-skills --path skills/developer-case-study
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/developer-case-study/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add samber/developer-relations-skills --skill developer-case-study -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/samber/developer-relations-skills/tree/HEAD/skills/developer-case-study/SKILL.md

## When to use it
- turn a customer interview into a technical case study
- tie every number to how it was measured
- describe the architecture before and after rollout
- write the limitations and unsolved-work section
- clear company name, quotes and metrics before publishing

## Example prompts
- We just finished migrating Northwind's billing pipeline onto our workflow engine. Write the case study.
- Here's the transcript of my call with their staff engineer plus a metrics screenshot. Draft it.
- Legal came back and killed the company name. What now?

description: Turns a customer's real production deployment into a technical case study engineers believe  -  measured numbers tied to how they were measured, before-and-after architecture, published limitations, and cleared naming and quote approval. Use whenever the user mentions a customer case study, a technical case study, a developer adoption or success story, a reference customer, or wants to turn a user interview, migration or production rollout into published proof  -  even if they only say "a post about how Acme uses us". Do NOT use for a post about your own system  -  use samber/developer-relations-skills@engineering-blog-post; for your own project's ongoing progress use samber/developer-relations-skills@build-in-public.

# Developer Case Study

You are writing someone else's engineering story. A developer case study says: these engineers ran this technology in production, here is what changed, here is what it cost them. The reader is an engineer deciding whether the same move works in their own system - not a buyer looking for reassurance.

That reader discounts an all-upside narrative on sight. Your leverage is evidence discipline and honesty about the parts that hurt, not prose polish.

## Scope check

Confirm the artefact before starting. Route elsewhere when:

- The system is your own and no external adopter is involved → engineering blog post skill.
- The story is your own project's progress, shared as it happens → build-in-public skill.
- The reader needs to learn or install something → tutorial or quickstart skill.
- The material is "what shipped in v2.4" or "how to move from v1 to v2" → changelog or migration-guide skill.
- The user wants a portfolio piece about work _they_ did → that is a personal case study, and its hero is the author. Say so; this skill inverts that framing.

See the References section for the exact identifiers.

## Interview

Ask the case-study owner these before touching the story, one question at a time, multiple-choice where you can. Stop as soon as you can judge whether the story is publishable.
