noeta-sdk 0.5.3

Noeta SDK: build AI agents that run on the server. Import noeta.sdk, define your tools and policy — durable event-sourced execution, multi-worker scheduling, provider-neutral, no vendor lock-in.

noeta-sdk

The thin in-process client surface (noeta.sdk facade — query / Client / Options / tool / extension interfaces) over the noeta-runtime kernel, plus the built-in plugin catalogue (noeta.builtins — every official capability implementation: the fs/web tool packs, provider adapters, guards, reminders, memory, browser, app, MCP, sandbox backends, skills, the ReAct policy) and the official presets. Like claude-agent-sdk / LangChain: import noeta.sdk, run an agent in-process; no engine internals, no HTTP server.

Part of the Noeta workspace. Apache-2.0.

Install

pip install noeta-sdk      # noeta-runtime comes along as a transitive dependency

Then import noeta.sdk — that single module is the whole public surface. Python 3.11+.

Quickstart — zero credentials

No API key, no network: drive one turn with the deterministic offline provider from noeta.sdk.testing.

import tempfile
from pathlib import Path

from noeta.sdk import Options, query, LLMResponse, TextBlock, Usage
from noeta.sdk.testing import FakeLLMProvider

provider = FakeLLMProvider(
    responses=[
        LLMResponse(
            stop_reason="end_turn",
            content=[TextBlock(text="Hello from a Noeta SDK agent!")],
            usage=Usage(uncached=1, output=1),
        )
    ]
)

with tempfile.TemporaryDirectory() as tmp:
    result = query(
        Options(
            system_prompt="You are a concise assistant.",
            allowed_tools=("read",),
            permission_mode="bypassPermissions",
        ),
        goal="Say hello.",
        provider=provider,
        workspace_dir=Path(tmp),
        model="stub-model",
    )
    assert result.answer() == "Hello from a Noeta SDK agent!"

query returns the full event-envelope stream for the turn; result.answer() reads the answer off the terminal envelope. Swap the FakeLLMProvider for a live adapter from noeta.sdk.providers (AnthropicProvider / OpenAICompatProvider) to connect a real model — the provider is wiring, not agent identity.
