# Agents

> Configuring and managing AI agents in Playgent

# Agents

An **Agent** is your AI system configuration in Playgent. It includes your LLM provider, credentials, system prompt, and default evaluation metrics.

## Quick Start

<CodeGroup>
  ```python Python theme={null}
  from playgent import Playgent

  client = Playgent(api_key="your-api-key")

  agent = client.agents.create(
      name="Customer Support Agent",
      provider="openai",
      credentials={"OPENAI_API_KEY": "sk-xxx..."},
      system_prompt="You are a helpful customer support agent for Acme Corp...",
      default_scorers=["answer_relevancy", "faithfulness", "bias"]
  )
  ```

  ```typescript TypeScript theme={null}
  import { Playgent } from "playgent";

  const client = new Playgent({ apiKey: "your-api-key" });

  const agent = await client.agents.create({
    name: "Customer Support Agent",
    provider: "openai",
    credentials: { OPENAI_API_KEY: "sk-xxx..." },
    systemPrompt: "You are a helpful customer support agent for Acme Corp...",
    defaultScorers: ["answer_relevancy", "faithfulness", "bias"],
  });
  ```
</CodeGroup>

## Configuration Options

### Supported Providers

| Provider    | Value       |
| ----------- | ----------- |
| OpenAI      | `openai`    |
| Anthropic   | `anthropic` |
| AWS Bedrock | `bedrock`   |
| LangChain   | `langchain` |
| Custom      | `custom`    |

### System Prompt

Base instructions for your agent. Used during test execution and prompt optimization.

### Default Scorers

Automatic evaluation metrics for all test runs:

```python theme={null}
agent = client.agents.create(
    name="Support Agent",
    provider="openai",
    default_scorers=["answer_relevancy", "faithfulness", "bias"]
)
```

### Custom Endpoints

For custom agent invocation:

```python theme={null}
agent = client.agents.create(
    name="Custom Agent",
    provider="custom",
    invocation={
        "url": "https://your-api.com/chat",
        "headers": {"X-API-Key": "your-key"}
    }
)
```
