Swarmauri Core
swarmauri_core provides the interface contracts for the Swarmauri SDK. It is the package component authors use when they need stable abstract interfaces for agents, tools, LLMs, parsers, vector stores, cryptography, signing, key providers, transports, middleware, billing, storage, XMP, and other composable intelligence infrastructure components.
Why Swarmauri Core?
swarmauri_core keeps component contracts separate from implementations. Package authors can depend on stable interfaces without pulling in every base class, provider adapter, model package, or runtime integration.
FAQ
Q: What belongs in swarmauri_core?
A: Interface contracts, protocol shapes, enums, and shared types for Swarmauri component families.
Q: Should application developers instantiate classes from this package?
A: Usually no. Most application code uses concrete implementations from swarmauri_standard, community packages, or provider-specific packages. Component authors use swarmauri_core to implement the correct contract.
Q: How does this package relate to swarmauri_base?
A: swarmauri_core defines interfaces. swarmauri_base implements reusable base classes and serialization behavior on top of those interfaces.
What Is Included?
The package is intentionally implementation-light. It defines contracts, protocol shapes, enums, and shared types so implementation packages can interoperate without depending on each other directly.
Major interface families include:
- Agents and agent APIs:
IAgent, conversation, parser, retrieval, toolkit, and vector-store agent mixins. - LLM and multimodal prediction: text LLMs, tool LLMs, OCR, STT, TTS, and VLM interfaces.
- Documents and parsing: document contracts, parser contracts, chunkers, conversations, prompts, and prompt templates.
- Retrieval and vectors: vector, matrix, tensor, metric, similarity, vector-store comparator, deprecated distance compatibility contracts, vector store, and document store contracts.
- Security and trust: crypto, MRE crypto, cipher suites, signing, proof-of-possession, token services, key providers, certificates, and XMP embedding.
- Runtime infrastructure: middleware, transports, storage adapters, publishers, rate limits, tracing, state, service registries, and pipelines.
- Business systems: billing provider interfaces for customers, payments, invoices, subscriptions, refunds, payouts, risk, reporting, webhooks, and marketplace flows.
Features
- Stable abstract interfaces for Swarmauri component packages.
- Shared types for crypto, signing, key management, transports, billing, and proof-of-possession workflows.
- Zero runtime dependencies.
- Interface-first design for packages that later inherit reusable behavior from
swarmauri_base. - Python 3.10, 3.11, 3.12, 3.13, and 3.14 support.
Installation
Install with uv:
uv add swarmauri_core
Install with pip:
pip install swarmauri_core
Usage
Use swarmauri_core when defining a new implementation package or validating that a class satisfies a public Swarmauri contract.
import asyncio
from typing import Any, Optional
from swarmauri_core.agents.IAgent import IAgent
from swarmauri_core.messages.IMessage import IMessage
class MinimalAgent(IAgent):
def exec(
self,
input_data: Optional[Any] = None,
llm_kwargs: Optional[dict] = None,
) -> Any:
return {"input": input_data, "kwargs": llm_kwargs or {}}
async def aexec(
self,
input_str: Optional[str | IMessage] = "",
llm_kwargs: Optional[dict] = None,
) -> Any:
return self.exec(input_str, llm_kwargs)
def batch(
self,
inputs: list[str | IMessage],
llm_kwargs: Optional[dict] = None,
) -> list[Any]:
return [self.exec(item, llm_kwargs) for item in inputs]
async def abatch(
self,
inputs: list[str | IMessage],
llm_kwargs: Optional[dict] = None,
) -> list[Any]:
return await asyncio.gather(
*(self.aexec(item, llm_kwargs) for item in inputs)
)
Implement a parser contract:
from pathlib import Path
from swarmauri_core.documents.IDocument import IDocument
from swarmauri_core.parsers.IParser import IParser
class PlainTextParser(IParser):
def parse(self, data: str | bytes | Path) -> list[IDocument]:
raise NotImplementedError("Return concrete Document instances here.")
Implement a storage or retrieval contract in a concrete package, then expose the class through swarmauri_base and the public swarmauri namespace when appropriate.
Component Author Workflow
- Choose the closest interface from
swarmauri_core. - Implement domain behavior in a package-specific class.
- Add reusable serialization and registration behavior with
swarmauri_basewhen the implementation should become a Swarmauri component. - Publish or register the implementation package through the appropriate
swarmauri.<kind>entry point or namespace mapping. - Document installation and usage in the implementation package README.
Related Packages
Foundational packages:
- swarmauri provides the namespace importer and plugin discovery layer.
- swarmauri_base provides reusable base classes built on these interfaces.
- swarmauri_standard provides first-party implementations for common component kinds.
Packages built around specific core component kinds:
- swarmauri_signing_ed25519 implements signing interfaces.
- swarmauri_crypto_composite composes crypto providers behind the crypto interface.
- swarmauri_keyprovider_inmemory implements key provider contracts.
- swarmauri_transport_stdio implements transport contracts.
- swarmauri_storage_memory implements storage adapter contracts.
- swarmauri_middleware_jsonrpc implements middleware contracts.
When To Use This Package
Use swarmauri_core when you are designing or implementing a Swarmauri-compatible component and need the interface contract. Use swarmauri_base when you also need reusable base-class behavior, serialization helpers, and component registration. Use swarmauri_standard when you want ready-to-use implementations.
