description: Reviews coroutine and Flow usage — scope choice, dispatcher, exception handling and collection in Compose. Use when the user asks for a review of coroutines, Flow, suspend functions or async code.

# Coroutine / Flow review

!`git diff --name-only main -- '*.kt'`

Read the files above that contain `suspend`, `launch`, `Flow` or
`collect`, and check:

1. **Scope** — is `GlobalScope` used anywhere? It should be
   `viewModelScope` in a ViewModel, and `rememberCoroutineScope`
   or `LaunchedEffect` in a Composable.
2. **Dispatcher** — is IO work on `Dispatchers.IO`?
   Is the dispatcher hardcoded or injected?
   (It should be injected, for testability.)
3. **Exceptions** — is an exception thrown inside `launch` caught?
   Is there a `try/catch` or a `CoroutineExceptionHandler`?
4. **Collection in Compose** — is `collectAsStateWithLifecycle`
   used, or plain `collectAsState`?
5. **Cancellation** — do long loops check `ensureActive()` or
   `isActive`?

Output: `file:line` plus a short explanation and a suggestion for
each finding. Do not modify files.

description: Writes a UI test for an existing Composable — createComposeRule, semantics finders and assertions. Use when the user wants a test written for Compose.

# Compose UI test: $composable

## Existing test examples

!`find . -path '*/androidTest/*' -name '*Test.kt' | head -3`

## Steps

1. Find the `$composable` function and read its parameters.
2. Read one of the existing tests above and follow the project's
   test style (naming, setup, fakes).
3. Write the test under `androidTest`:
   - `createComposeRule()` when no Activity is needed
   - `createAndroidComposeRule<T>()` when one is
4. Cover: the initial state, a user action, the result, and the
   empty/error state if there is one.
5. Run `./gradlew :app:compileDebugAndroidTestKotlin`.

Note: finding by text (`onNodeWithText`) breaks when localisation
changes. Prefer `testTag`, adding `Modifier.testTag(...)` to the
Composable where needed.
