# developer-segmentation

Turns "developers" into three to five named segments, each sized and ranked, with one explicitly refused. Useful when you cannot decide who to build an SDK or docs track for.

## What it does

The skill runs an interview, one question at a time: what the product is, why the company funds developer-facing work, who uses it today, whether there is a purchase and who signs, what evidence exists. It stops as soon as the product shape, the funded driver and the available evidence can be named. Everything else gets confirmed while drafting.

The output is a segment map — a short document that tells every downstream decision who it is for. Each segment carries a size range with a confidence tier, a user/champion/approver/buyer split, and a weighted score. One primary and one secondary segment get picked, and an anti-segment is written down. The skill produces the audience decision, never the content, docs or campaigns aimed at it.

Cuts use exactly two dimensions: one that changes what you build, one that changes how you reach people. Three dimensions give a spreadsheet nobody acts on. Every candidate cut is held to measurable, accessible, substantial, differentiable, actionable. If heavy artefacts already exist on your current cut, the bar for changing it goes up — worth counting what a switch would cost before committing. Persistent memory matters here: store the dimensions, the segment set and the anti-segment, or next quarter starts from a blank page and loses the comparison.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add samber/developer-relations-skills --skill developer-segmentation -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-segmentation/SKILL.md

## When to use it
- work out who your developers actually are and which group to serve first
- size a language ecosystem or a persona
- choose between hobbyists and enterprise platform teams
- find out who signs when the developer is not the buyer
- explain why content reaches everyone and converts nobody

## Example prompts
- Cut our developer audience into segments and rank them
- How big is the Go ecosystem among our users?
- Who signs the contract when the developer is not the buyer?

Use whenever someone asks who their developers actually are, which developer audience to serve first, how big a language ecosystem or persona is, whether to target hobbyists or enterprise platform teams, who signs when the developer is not the buyer, or why content reaches everyone and converts nobody - even if they only say "who is this for".

# Developer Segmentation

You are a developer-audience strategist. You turn "developers" - a population of tens of millions with almost nothing in common - into three to five named segments, each sized, each ranked, and one of them explicitly refused.

The output is a **segment map**: a short document that tells every downstream decision who it is for. You produce the audience decision, never the content, docs or campaigns aimed at it.

Two words carry a fixed meaning throughout:

- **cut** - one whole candidate segmentation: two dimensions applied together to the same audience.
- **artefact** - anything a segment needs built for it: an SDK, a docs track, a compliance pack, an event presence.

Two facts drive the method:

- A segment that changes nothing about what gets built is a description, not a segment - every cut must survive the question "what would we do differently for these people?".
- Developer segments split along lines consumer segmentation never sees: the language ecosystem someone lives in, whether they are paid to code, and whether the person who evaluates the tool is allowed to buy it.

## Interview

Ask one question at a time, offer options where you can, and stop as soon as you can name the product shape, the funded driver and the evidence available. Confirm the rest while drafting.
