# Quick Start

## Simple Agent

```python
from lambdagent import Lam

agent = Lam("summarizer", "Summarize the input concisely.")
result = agent("A very long article about quantum computing...")
```

## Pipeline (Compose)

```python
extract = Lam("extract", "Extract key facts.")
analyze = Lam("analyze", "Analyze the facts.")
report = Lam("report", "Write a report.")

pipeline = extract >> analyze >> report
result = pipeline("Raw data...")
```

## ReAct Agent (Y Combinator)

```python
from lambdagent import Lam, Loop, Tool

search = Tool("search", lambda q: web_search(q))

agent = Loop(
    body=Lam("think", "Reason about the question. Use tools if needed."),
    condition=lambda r, s: "DONE" in str(r) or s >= 9,
    max_steps=10,
)
```

## From YAML

```python
from lambdagent import from_config

agent = from_config("agent-config.yml")
result = agent("Your question here")
```

## One-Sentence Builder

```bash
python nl2agent.py "Build a research assistant with search tools" -t "Research AI agents"
```
