maivn-contracts

maivn-contracts contains the typed wire models, JSON Schemas, loaders, and validators shared by mAIvn services and the Python SDK.

Install

pip install maivn-contracts

Import from a focused public namespace rather than from its implementation modules:

from maivn_contracts.events import Event, validate_event
from maivn_contracts.messages import Message, validate_message
from maivn_contracts.tools import ToolCall, validate_tool_call

The package exposes contract families for agents, artifacts, events, messages, resources, runtime state, scenarios, swarms, tools, toolsets, and workers. Each family's load_*_schema functions return the checked-in schema, validate_* functions validate untrusted wire data, and Pydantic models provide typed construction and parsing.

Treat schemas and their canonical encodings as protocol boundaries. Do not copy private fields into logs or relax a validator only in one consumer. Update the shared contract and all affected producers and consumers together.
