# Agents

> The @agent / @tool model, streaming and an HTTP surface.

`pyrula.agents` runs agents on the durable [workflow](https://docs.pyrula.io/workflows.md) engine. Finished LLM and tool calls are journaled, so a crashed turn resumes without repeating paid calls.

```python
from pyrula.agents import agent, tool
```
