mistralai-vibe-sdk 0.4.0

Vibe SDK

Vibe SDK

High-level Python interface for running Vibe protocol agents.

The SDK distribution also ships the legacy mistralai.vibe.protocol.* namespace for compatibility while the consolidation moves internals toward SDK-owned contexts.

The SDK gives you:

• Agent and stateful async/sync sessions
• Pydantic-based tool authoring
• Built-in filesystem tools
• Client-handled tools for UI- or host-dependent actions, such as asking the user a question

Quick Start

from mistralai.vibe.sdk import Agent, AgentConfig
from mistralai.vibe.sdk.execution_record.patching.json_patch import apply_patches
from mistralai.vibe.sdk.execution_record.state import TaskState
from mistralai.vibe.sdk.transports.events import TaskResultEvent, TaskStateUpdateEvent

agent = Agent(
    config=AgentConfig(
        model="mistral-large-latest",
        system_prompt="You are a concise assistant.",
    )
)

async with agent.session() as session:
    state = TaskState(input="Hello")
    async for event in session.run("Hello"):
        if isinstance(event, TaskStateUpdateEvent):
            state = apply_patches(state, event.payload.patches)
        elif isinstance(event, TaskResultEvent):
            state = event.payload.result

    print(state.output)
