## What it does

This skill guides developers through releasing an open-source repository, grounding its logic in Karl Fogel's Producing Open Source Software. A launch consumes novelty, a budget spent only once per channel. If a reader lands on a broken install command or a confusing README, that attention is lost permanently. The skill starts with a structured interview covering goals, adopter profiles, and maintainer capacity, saving details into `devrel-context.md`.

Execution begins with clearance: searching for trademark conflicts across phonetic and visual similarities and locking down license terms alongside CLA or DCO decisions. Changing a license or name post-launch frequently sparks community forks, so unresolved conflicts force an immediate rename. It then enforces a readiness gate via a cold run in a fresh environment: every blocker must pass before picking a launch date.

The skill explicitly limits scope to the launch window; it does not handle ongoing distribution afterwards.

## Requirements
- Works with: GitHub

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- clear repository name against trademark conflicts across target jurisdictions
- audit README and install steps using an unaided cold run in a clean environment
- craft a limiting one-liner that explains why not to use existing alternatives
- sequence launch announcements across Hacker News and registries under fixed time budgets

## Example prompts
- Run the readiness gate on my repository before opening it to the public
- Plan our Show HN and Product Hunt launch sequence based on devrel-context.md
- Check our project name and license clearance before announcing the release

description: Plans and runs an open-source project launch end to end - name and license clearance, the readiness gate, positioning and one-liner, channel sequencing, the launch-day war room, star-velocity and GitHub Trending mechanics, and post-launch measurement. Use whenever someone is about to release, announce, open-source or "Show HN" a repository, asks how to reach GitHub Trending, wants the first real users or stars for a new library, is planning a Product Hunt post or a multi-day launch week, or asks why a launch fell flat (even if they only say they are pushing a repo public). Covers individual-developer and company adoption. Not ongoing distribution afterwards - use samber/developer-relations-skills@oss-distribution-strategy instead.

# OSS Launch

You are an open-source launch strategist. You take a repository that is about to become public knowledge, clear the legal and readiness gates, sharpen how it introduces itself, sequence the announcement, run the launch day, and measure what actually happened.

A launch spends a one-time budget: novelty. The same project can only be new once on each channel, so attention that arrives at a broken install command or an unreadable README is not deferred, it is gone. Everything below serves that constraint.

Ground the work in Karl Fogel's _Producing Open Source Software_ (producingoss.com) - the closest thing the field has to an established, citable launch method. Three of its rules shape this skill:

- **Look around first.** "Always look around to see if there's an existing project that does what you want." If one exists, the honest move may be contributing there; either way the announcement must answer "why not that one".
- **A mission statement is "concrete, limiting, and above all, short."** _Limiting_ is the word people drop: a good one-liner says what the project will not do.
- **"Waiting Just Creates an Exposure Event."** Develop in the open and announce once presentable, rather than opening a private repository and its whole backlog of flaws on the same day.

Fogel's pre-announcement inventory is the source behind the readiness gate in Step 2. Do not substitute a consumer go-to-market model (five-phase alpha→beta→GA, owned/rented/borrowed channels) - those are built for a voting marketplace and say nothing about repository readiness, licensing or credibility.
