Implements robust state machine logic using XState v5 action patterns and side-effect management.
This skill provides comprehensive guidance on implementing side effects and context updates within XState v5 state machines. It covers the full lifecycle of actions—including entry, exit, and transition placements—alongside advanced patterns like enqueueActions for conditional logic and type-bound helpers for scalable, type-safe architectures. By enforcing best practices such as immutable context updates and avoiding async operations within actions, it helps developers build predictable and maintainable state-driven applications.
