Vystak core SDK — declarative AI agent orchestration

vystak

Core SDK for Vystak — declarative, platform-agnostic orchestration for AI agents.

This package provides the foundational schema, hashing engine, provisioning graph, and provider base classes that the rest of the Vystak ecosystem builds on. You typically don't install this directly — use vystak-cli instead, which pulls it in.

Install

pip install vystak

What's in this package

• vystak.schema — Pydantic models for Agent, Model, Provider, Platform, Channel, Service, Skill, Workspace, Secret, Mcp. This is the contract adapters and providers consume.
• vystak.hash — content-addressable hashing (AgentHashTree) for stateless change detection.
• vystak.provisioning — ProvisionGraph, a DAG of Provisionable nodes for topological resource rollout with health checks.
• vystak.providers — PlatformProvider, FrameworkAdapter, ChannelAdapter ABCs.
• vystak.stores — async SQLite-backed key-value store for long-term memory.

Example

import vystak as ast

anthropic = ast.Provider(name="anthropic", type="anthropic")
model = ast.Model(name="claude", provider=anthropic, model_name="claude-sonnet-4-20250514")
agent = ast.Agent(name="support-bot", default_model=model)

See the main repository for the full CLI, adapters, and providers.
