Coroutine patterns, Flow operators, Jetpack Compose state management, Ktor routing, and Kotlin Multiplatform shared code.

One of 2 test cases the skill fixed. Same model, same prompt, with and without the skill.
I need a Kotlin repository function that accepts a flow of search query text and outputs a flow of product search results. Please provide the repository method using Flow operators to handle live search input efficiently (filtering out rapid keystrokes and overly brief queries) and gracefully handling backend network failures.
| Checked | Without skill | With skill |
|---|---|---|
| uses debounce to delay emissions from rapid query text changes | Passed | Passed |
| uses flatMapLatest to switch to the latest search query coroutine | Passed | Passed |
| catches exceptions in inner flow without swallowing coroutine cancellation | Missed | Passed |
