Python SDK for Vouchstone — AI engineers you can vouch for

Vouchstone SDK

Python SDK for building AI agents on the Vouchstone platform — the first accountable AI engineering firm.

Install

pip install vouchstone-sdk

# With vector memory (ChromaDB)
pip install vouchstone-sdk[vector]

# With graph memory (Neo4j)
pip install vouchstone-sdk[graph]

# Everything
pip install vouchstone-sdk[all]

Quick Start

from vouchstone_sdk import Agent, AgentConfig, Message

class MyAgent(Agent):
    async def run(self, message: Message, context: dict):
        relevant_docs = context.get("semantic", [])
        history = context.get("episodic", [])

        response = await self.llm.complete(
            system=f"You are {self.config.name}. Use the context to help the user.",
            messages=[{"role": "user", "content": message.content}],
            context=relevant_docs,
        )
        return AgentResponse(content=response)

config = AgentConfig(
    name="Data Migration Agent",
    model="claude-sonnet-4-20250514",
    semantic_memory=True,
    episodic_memory=True,
    procedural_memory=True,
)

agent = MyAgent(config)
await agent.initialize(vector_db_url="http://chromadb:8000")
response = await agent.process(Message(content="Migrate our PostgreSQL to Snowflake"))

5-Layer Memory Stack

Each agent has access to a biologically-inspired memory architecture:

Layer	Name	Storage	Purpose
1	Working	Redis	Current turn context (resets per session)
2	Episodic	PostgreSQL	Cross-session traces (append-only)
3	Semantic	ChromaDB	Entity store (vector search)
4	Procedural	Neo4j	Learned skills (versioned DAG)
5	Meta	Control Plane	Decay, dedup, compress, forget

Control Plane Client

from vouchstone_sdk import VouchstoneClient

client = VouchstoneClient(
    api_url="https://api.vouchstone.ai",
    api_key="your-api-key",
    tenant_id="your-tenant-id",
)

# List agents
agents = await client.list_agents()

# Execute an agent
result = await client.execute(agent_id="...", input={"content": "Hello"})
