Key Recommendations
- Prefer Setup Stores for complex logic, composables, and watchers
- Use
storeToRefs()when destructuring state/getters to preserve reactivity - Actions can be destructured directly - they're bound to the store
- Call stores inside functions not at module scope, especially for SSR
- Add HMR support to each store for better development experience
- Use
@pinia/testingfor component tests with mocked stores

Useful defaults in pinia — fewer surprises than typical one-off scripts, and it plays nicely with `npx skills` flows.
