frankstate 0.1.2

Frank brings order and helps you build complex LLM workflows using scalable, testable, and reusable components.

🧟 frankstate

frankstate is a lightweight pattern layer for assembling LangGraph workflows with clearer structure, stronger boundaries, and less duplicated graph wiring.

It does not replace LangGraph and it does not introduce a separate runtime. The compiled result is still a native LangGraph graph built with official LangGraph primitives.

What The Package Provides

The published package focuses on reusable workflow assembly contracts:

• WorkflowBuilder to compile a graph from a layout class.
• GraphLayout to separate runtime dependency construction from graph declaration.
• SimpleNode, CommandNode, SimpleEdge, and ConditionalEdge to model graph structure.
• StateEnhancer, StateEvaluator, and StateCommander to keep node and routing logic aligned with LangGraph concepts.
• NodeManager and EdgeManager to normalize layout declarations into LangGraph registration calls.

Public API

The package root intentionally exports only:

from frankstate import WorkflowBuilder

All other reusable contracts should be imported from subpackages, usually from their concrete modules:

from frankstate.entity.graph_layout import GraphLayout
from frankstate.entity.node import SimpleNode, CommandNode
from frankstate.entity.edge import SimpleEdge, ConditionalEdge
from frankstate.entity.statehandler import StateEnhancer, StateEvaluator, StateCommander
from frankstate.entity.runnable_builder import RunnableBuilder
from frankstate.managers.node_manager import NodeManager
from frankstate.managers.edge_manager import EdgeManager

Installation

With pip:

pip install frankstate

With uv:

uv pip install frankstate

Optional example dependencies:

pip install frankstate[examples]

The published wheel contains only frankstate. Repository-level reference code, service integrations, notebooks, and tests are not part of the base package.

Minimal Example

from frankstate import WorkflowBuilder
from my_project.layouts.simple_graph import SimpleGraphLayout
from my_project.state import GraphState

workflow_builder = WorkflowBuilder(
    config=SimpleGraphLayout,
    state_schema=GraphState,
)

graph = workflow_builder.compile()

LangGraph Alignment

frankstate keeps the official LangGraph execution model:

• StateEnhancer wraps node logic that returns partial state updates.
• StateEvaluator wraps the callable used by conditional edges.
• StateCommander wraps nodes that return official LangGraph Command objects.

The compiled graph still relies on LangGraph's own StateGraph, add_node(), add_edge(), add_conditional_edges(), and Command.

Repository Boundaries

If you are browsing the repository instead of the published package:

• src/frankstate is the reusable package.
• src/core_examples is the repository reference layer.
• src/services contains repository integrations and deployment entrypoints.

Those repository layers help demonstrate how frankstate can be consumed, but they are not the stable public API of the base wheel.
