What You Can Do

You can build AI-powered Python agents quickly using the @agentic decorator for simple functions or spawn() for full multi-agent systems with behavioral control. Agents maintain persistent state, integrate with MCP tools, handle typed return values, and coordinate with each other through a unified framework—enabling everything from basic AI-enhanced functions to complex agent orchestration pipelines.

Features

Simple @agentic decorator

Turn any async function into an AI agent with minimal code

Spawn multi-agent systems

Create and control multiple agents with spawn() for orchestration

Type-safe return values

Specify expected output types (int, dict, custom objects) and get validated results

MCP tool integration

Connect agents to external tools and services through Model Context Protocol

Persistent state management

Agents maintain memory and context across multiple invocations

Flexible prompting

Use premise for character/behavior or system for full control

Per-call scope

Pass tools and context dynamically at invocation time

Behavioral debugging

Full control over agent reasoning and decision-making

Example Output

Example 1: Simple agentic function

code
@agentic()
async def summarize(text: str) -> str:
    """Summarize the given text"""
    ...

result = await summarize("Long document here...")
# Returns: "Concise summary of the document"

Example 2: Multi-agent system with tools

code
agent = await spawn(
    premise="You are a data analyst.",
    scope={"analyze": my_analyzer, "query_db": db_query}
)

result: dict[str, int] = await agent.call(
    dict[str, int],
    "Analyze Q3 sales trends"
)
# Returns: {"growth": 23, "peak_month": 7}

Example 3: Agent coordination

code
researcher = await spawn(premise="Research expert")
writer = await spawn(premise="Technical writer")

findings = await researcher.call(str, "Research AI safety")
article = await writer.call(str, f"Write about: {findings}")
