## What it does

Fishjam is Software Mansion's hosted WebRTC platform. This skill kicks in before the agent writes, reviews or debugs code that talks to a Fishjam instance — from a Node or Python backend, or from a React, React Native and Expo client. Skip it and the model mixes up the data model and method names.

It routes you to sub-skills under `references/`. Start with `references/platform/SKILL.md` for rooms, peers, tracks, tokens and notifications, then pick the one matching your build: `js-server-sdk`, `python-server-sdk`, `react-client`, `react-native-client`, `composition`. Svelte, Vue and web workers drop to `@fishjam-cloud/ts-client`; plain REST lives in `references/platform/rest-endpoints.md`.

Two things break production. The management token stays on the backend — if it leaks, regenerate it from the Dashboard. A peer token is valid for 24 hours from creation and is consumed during the initial WS handshake, so a peer that has not connected yet, or needs to reconnect later, requires `refreshPeerToken` (`refresh_peer_token`). Sandbox API URLs are dev-only: anyone holding one can create rooms on your account, which is why they never ship in a client build.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill fishjam -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill fishjam -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill fishjam -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install software-mansion-labs/skills fishjam
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill fishjam -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/software-mansion-labs/skills --path skills/fishjam
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add software-mansion-labs/skills --skill fishjam -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/software-mansion-labs/skills/tree/HEAD/skills/fishjam/SKILL.md

## When to use it
- create a room and hand a peer token to a client from Node
- wire a React app to Fishjam through the provider
- refresh an expired peer token so a peer can reconnect
- build a composed stream with overlays and restreaming
- learn the room, track and notification model before coding

## Example prompts
- Write an Express backend that creates a Fishjam room and returns a peer token
- Add FishjamProvider to my React app and connect the camera
- A peer dropped after a day — how do I refresh its token with refreshPeerToken?

# Fishjam

Software Mansion's hosted WebRTC platform. Routes between platform fundamentals, the four SDKs, and compositions.

Read the **`references/platform/SKILL.md`** first for the domain model (rooms, peers, tracks, tokens, notifications). Then read the SDK sub-skill that matches what you're building. All sub-skills are in `references/`.

## Which sub-skill do I need?
