Creates AsyncRedux (Flutter) actions that return null from reduce() to not change the state. Such actions can still do side effects, dispatch other actions, or do nothing.

Use the Event class to interact with Flutter's stateful widgets (TextField, ListView, etc.). Covers creating Event objects in state, consuming events with `context.event()`, scrolling lists, changing text fields, and the event lifecycle.

Add the Retry mixin for automatic retry with exponential backoff on action failure. Covers using Retry alone for limited retries, combining with UnlimitedRetries for infinite retries, and configuring retry behavior.

Creates AsyncRedux (Flutter) synchronous actions that update state immediately by implementing reduce() to return a new state.

implement-cqrs-handler

Execute a **single phase** from an implementation plan with comprehensive quality gates. This skill is designed to be called by `implement-plan` but can also be invoked directly.

implement-retry-logic

Implements functions following project conventions. Applies data-first parameter order, currying patterns with *On and *With variants, and consistent universal operation names.

Solve problems by thinking backwards. Use when forward thinking is stuck, you need to identify risks, or find non-obvious solutions. Not for straightforward implementation tasks or simple bug fixes.
