AGNT5 Python SDK
Build reliable AI agents and durable workflows in Python. The AGNT5 SDK provides typed components, workflow checkpoints, retries, streaming, tools, human-in-the-loop coordination, evaluation, and runtime observability.
Requirements
- Python 3.11 or newer
- An AGNT5 runtime for deployed execution
Installation
pip install agnt5
Quick start
Define a function. Type hints are used to derive its input and output schema.
from agnt5 import FunctionContext, function
@function(retries=3, backoff="exponential")
async def greet(ctx: FunctionContext, name: str) -> dict[str, str]:
ctx.logger.info("greeting user", extra={"name": name})
return {"message": f"Hello, {name}!"}
Register application components with a worker for runtime-backed execution:
import asyncio
from agnt5 import Worker
async def main() -> None:
worker = Worker(service_name="hello-python")
await worker.run()
asyncio.run(main())
Decorated functions, workflows, agents, tools, and scorers are registered when
their modules are imported. See examples/app.py for a
complete application entrypoint.
Invoke a deployed component
from agnt5 import Client
client = Client(
gateway_url="https://gw.agnt5.com",
api_key="agnt5_sk_...",
deployment_id="deployment-id",
)
result = client.run("greet", {"name": "Ada"})
print(result)
Client also supports asynchronous submission, status and result polling,
streaming events, batches, cancellation, workflow resume, chat, and evaluation.
Configuration can be supplied explicitly or through AGNT5_GATEWAY_URL,
AGNT5_API_KEY, and AGNT5_DEPLOYMENT_ID.
Core APIs
| API | Purpose |
|---|---|
@function |
Typed, retryable units of work |
@workflow |
Durable multi-step orchestration and checkpointing |
Agent and @agent |
Model and tool orchestration |
@tool |
Typed tools with generated schemas |
ctx.state |
Durable workflow and component state |
ctx.memory |
Conversation and application memory |
Client / AsyncClient |
Invoke and observe deployed components |
Worker |
Register components and serve runtime dispatch |
The shared Rust runtime foundation lives in
agnt5dev/sdk-core. Vendor sandbox
adapters live in
agnt5dev/sdk-integrations.
Examples and documentation
examples/contains functions, workflows, agents, tools, streaming, HITL, MCP, chat, and evaluation examples.docs/contains SDK-specific guides.- AGNT5 documentation covers platform concepts and deployment.
Development
uv sync --all-groups
uv run ruff check src tests
uv run pytest tests/unit -q
uv build --sdist
Development builds use a sibling checkout of
sdk-core.
