State Machine - Finite State Machines for Complex Flows

Description

Enforces deterministic, minimal state machines for any multi-step flow in NodeJS-Starter-V1. Codifies the project's existing patterns (TaskStatus, ExecutionStatus, NodeStatus) and provides a reusable framework for defining states, transition maps, guard conditions, and side effects across Python and TypeScript.

When to Apply

Positive Triggers

• Designing multi-step workflows with distinct status phases
• Adding new Enum status fields to Pydantic models
• Implementing UI components with loading/error/success states
• Reviewing state transitions for completeness and determinism
• Adding retry, escalation, or verification loops
• User mentions: "state machine", "status", "workflow state", "transitions", "FSM"
