What problem does it solve? It guides developers in defining Redux action creators correctly with the Themis library, preventing duplicate action-type ownership, payload shape drift, and miswired async request/success/failure flows. ## Core Features & Use Cases - Action Creator Patterns: Covers createAction with tuple payload typing, payload modifiers, and namespaced action types like sliceName/actionName. - Async Action Triplets: Explains createAsyncAction request creators with static .success and .failure creators, plus per-instance creators on dispatched requests. - Saga and Reducer Integration: Shows how reducers consume actions via .with() handlers and how sagas watch request creators directly with takeEvery/takeLatest. - Use Case: When adding a todos/rename action, search for existing owners first, define one canonical creator with a tuple payload, and wire it to reducers and sagas without duplicating the type string. ## Quick Start Ask the AI to create a Themis async action for loading a todo by ID, including the request, success, and failure creators wired to a saga watcher.
