## What it does

This skill guides the setup of an ElevenLabs conversational voice agent. It covers voice, model, opening message, and a system prompt built around role, communication context, tone, goal, guardrails, and tool calls.

It covers `@elevenlabs/react`, `@elevenlabs/client`, and `@elevenlabs/react-native` for application integration, plus `@elevenlabs/elevenlabs-js` for server API work. The full API package uses Node.js `child_process`, so it will not run in a browser. That is a reason to use `@elevenlabs/client` or put a proxy server in front of it.

The skill also handles browser tools, webhook tools, and knowledge-base uploads from PDFs, text files, or URLs. ElevenLabs MCP expects direct JSON-RPC HTTP responses using protocol `2024-11-05`; SSE responses and `text/event-stream` fail here. The skill is compatible with Claude Code only.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill elevenlabs-agents -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill elevenlabs-agents -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill elevenlabs-agents -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jezweb/claude-skills elevenlabs-agents
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill elevenlabs-agents -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jezweb/claude-skills --path plugins/integrations/skills/elevenlabs-agents
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jezweb/claude-skills --skill elevenlabs-agents -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/jezweb/claude-skills/tree/HEAD/plugins/integrations/skills/elevenlabs-agents/SKILL.md

## When to use it
- create an ElevenLabs voice agent
- write an agent prompt with guardrails
- integrate the React or React Native SDK
- keep webhook API keys out of source code
- fix an ElevenLabs MCP server that returns SSE

## Example prompts
- "Create an ElevenLabs voice agent and configure its tools."
- "Integrate `@elevenlabs/react` into my React app."
- "Check my ElevenLabs MCP integration; the server returns SSE."

# ElevenLabs Agent Builder

Build a production-ready conversational AI voice agent. Produces a configured agent with tools, knowledge base, and SDK integration.

## Packages

```bash
npm install @elevenlabs/react           # React SDK
npm install @elevenlabs/client          # JavaScript SDK (browser + server)
npm install @elevenlabs/react-native    # React Native SDK
npm install @elevenlabs/elevenlabs-js   # Full API (server only)
npm install -g @elevenlabs/agents-cli   # CLI ("Agents as Code")
```

**DEPRECATED:** `@11labs/react`, `@11labs/client` -- uninstall if present.

**Server-only warning:** `@elevenlabs/elevenlabs-js` uses Node.js `child_process` and won't work in browsers. Use `@elevenlabs/client` for browser environments, or create a proxy server.

## Workflow

### Step 1: Create Agent via Dashboard or CLI

**Dashboard:** https://elevenlabs.io/app/conversational-ai -> Create Agent

**CLI (Agents as Code):**
```bash
elevenlabs agents init
elevenlabs agents add "Support Bot" --template customer-service
# Edit agent_configs/support-bot.json
elevenlabs agents push --env dev
```

Templates: `default`, `minimal`, `voice-only`, `text-only`, `customer-service`, `assistant`.

Configure:
- **Voice** -- Choose from 5000+ voices or clone
- **LLM** -- GPT, Claude, Gemini, or custom
- **System prompt** -- Use the 6-component framework below
- **First message** -- What the agent says when conversation starts

### Step 2: Write the System Prompt

Use the 6-component framework for effective agent prompts:

**1. Personality** -- who the agent is:
```
You are [NAME], a [ROLE] at [COMPANY].
You have [EXPERIENCE]. Your traits: [LIST TRAITS].
```

**2. Environment** -- communication context:
```
You're communicating via [phone/chat/video].
Consider [environmental factors]. Adapt to [context].
```

**3. Tone** -- speech patterns and formality:
```
Tone: Professional yet warm. Use contractions for natural speech.
Avoid jargon. Keep responses to 2-3 sentences. Ask one question at a time.
```

**4. Goal** -- objectives and success criteria:
```
Primary Goal: Resolve customer issues on the first call.
Success: Customer verbally confirms issue is resolved.
```

**5. Guardrails** -- boundaries and ethics:
```
Never: provide medical/legal/financial advice, share confidential info.
Always: verify identity before account access, document interactions.
