SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

State-machine-modeling prevents boolean sprawl by making lifecycle states, transitions, guards, and side effects explicit and verifiable, so illegal states and unsafe flows become impossible or detectable.

Core Features & Use Cases

Lifecycle state definitions: Model observable states as nouns/adjectives and cover terminal, retryable, and compensating states.
Transition rules with guards: Define triggers and preconditions so transitions are legal only when invariants hold.
Transition-table verification: Specify deterministic behavior for invalid transitions and require tests for allowed and forbidden transitions.

Quick Start

Use the state-machine-modeling skill to define the lifecycle states and allowed transitions for your workflow’s status field, including guards, side effects, and deterministic invalid-transition behavior.

FAQPage Schema

How do I prevent invalid state transitions and boolean sprawl in domain workflows?▼

Preventing invalid state transitions requires explicit finite state machine modeling where states, triggers, and guards are defined as verifiable rules. This approach eliminates boolean sprawl by making legal lifecycle behavior deterministic, ensuring forbidden transitions are detectable or impossible to execute.

What is a finite state machine for modeling software lifecycle behavior?▼

A finite state machine for software lifecycle modeling is a structural pattern that defines observable states as nouns, transitions with preconditions, and deterministic error behavior for invalid changes. It replaces scattered boolean flags with an explicit transition table to guarantee workflow invariants hold.

How do I model retry and compensation states for background jobs?▼

Modeling retry and compensation states for background jobs involves defining terminal, retryable, and compensating states within a finite state machine. You specify transition guards that check invariants before allowing retries, ensuring side effects execute only when preconditions are met.

How do I test finite state machine transitions for forbidden states?▼

Testing finite state machine transitions requires a transition-table verification approach where you specify deterministic behavior for both allowed and forbidden transitions. You write tests asserting that invalid transitions produce defined error behavior and that guards prevent illegal state changes.

When should I use state machine modeling instead of status flags for control flow?▼

State machine modeling should be used instead of status flags when impossible combinations of flags must be prevented in status-driven control flow. It is necessary for product workflows, domain lifecycles, and integration processes where transition guards and side effects ensure invariant safety.

Can I model parallel regions and mutual exclusivity in a state machine?▼

Modeling parallel regions and mutual exclusivity in a state machine is supported by requiring explicit transition methods and mutual exclusivity checks. Parallel regions allow concurrent state tracking, while deterministic rules ensure that conflicting states remain mutually exclusive.
