📝 Example: Creating an AI Function
OpenClaw (Skill-based)
# Create a custom skill
# skills/my-skill.py
from openclaw import Skill
@skill(name="sentiment-analyzer")
def analyze_sentiment(text: str) -> dict:
'''
Analyze sentiment of text
Returns: positive, negative, neutral
'''
# Use LLM via OpenClaw SDK
result = llm.complete(
model="gpt-4",
messages=[{
"role": "user",
"content": f"Analyze: {text}"
}]
)
return {
"sentiment": result.choice,
"confidence": 0.95
}
# Install and run
# openclaw install ./my-skill
# openclaw run sentiment-analyzer --text "Great!"
Magentic (Decorator)
# Add AI to any Python function
from magentic import prompt
from pydantic import BaseModel
class SentimentResult(BaseModel):
sentiment: str
confidence: float
@prompt("Analyze sentiment: {text}")
def analyze_sentiment(text: str) -> SentimentResult:
'''
Magentic automatically:
- Calls the LLM
- Parses response into BaseModel
- Provides type hints
'''
pass
# Use like a normal function
result = analyze_sentiment("Great product!")
print(result.sentiment) # "positive"
print(result.confidence) # 0.95
⚡ Example: Async Operations
OpenClaw
from openclaw import Skill
import asyncio
@skill(async_enabled=True)
async def scrape_multiple(urls: list[str]) -> list:
'''
Scrape multiple URLs concurrently
'''
tasks = [
scrape_url(url)
for url in urls
]
return await asyncio.gather(*tasks)
# OpenClaw handles concurrency
# max_concurrent: 10 in config.yaml
Magentic
from magentic import prompt, AsyncChat
import asyncio
@prompt("Summarize: {url}")
async def summarize_url(url: str) -> str: ...
# Use native Python async
async def main():
urls = ["url1", "url2", "url3"]
results = await asyncio.gather(*[
summarize_url(url)
for url in urls
])
return results
# You control concurrency
asyncio.run(main())
🌊 Example: Streaming Responses
OpenClaw
from openclaw import Skill
@skill(stream=True)
def stream_response(prompt: str):
'''
Stream LLM responses in real-time
'''
for chunk in llm.stream(
model="gpt-4",
prompt=prompt
):
yield chunk
# CLI automatically handles streaming
# openclaw run stream-response \
# --prompt "Tell me a story"
Magentic
from magentic import prompt_stream
from openai import AsyncOpenAI
@prompt_stream("Tell me about: {topic}")
def stream_response(topic: str):
'''
Magentic supports streaming
with async generators
'''
# Returns an async generator
pass
async def main():
async for chunk in stream_response("AI"):
print(chunk, end="", flush=True)
asyncio.run(main())
Deep Dive
Understanding the key differences in philosophy and design
🎯 Philosophy & Design
Platform vs Library
OpenClaw is a complete platform with CLI, server, authentication, logging, monitoring, and a skill marketplace. It's designed to run as a standalone service.
Magentic is a focused Python library that does one thing exceptionally well: turn LLM calls into typed Python functions. It's designed to be integrated into your existing applications.
Ecosystem vs DIY
OpenClaw provides 5000+ pre-built skills for common tasks (web scraping, API calls, data processing). You install skills like packages.
Magentic gives you the building blocks to create your own typed AI functions. You build everything yourself, but with full control.
Operations Focused vs Developer Focused
OpenClaw is built for production operations: resource limits, timeouts, audit logs, error recovery, scaling, monitoring. It's designed to be deployed and managed.
Magentic is built for developer experience: clean API, type hints, IDE autocomplete, Pydantic integration. It's designed to make writing AI-powered code delightful.
