+# Kotlin clean code

+- If a function, variable, or small wrapper is used **once**, inline it at the call site unless it clarifies a non-obvious boundary (network call, animation controller, crypto).
+- Prefer existing project components (`ActionButton`, `Category`, `ExpressiveStepFlow`, `apiRequest`) over new abstractions.
+- Match surrounding naming, imports, and composable structure; read adjacent files before adding helpers.
+- Extract only when shared by **2+** call sites or when the block exceeds ~40 lines of non-trivial logic (pager math, crypto, API wiring).
+- No hardcoded user-visible strings in shared UI — use Compose Multiplatform resources (`composeResources/values/strings.xml` + `values-ru`).

+Do **not** run `rg` / ripgrep in terminal commands. It is unreliable in this environment.

+- **Cursor Grep tool** — preferred for searching the codebase
+- **`grep -r`** — if a shell search is truly needed
