One of 18 test cases the skill fixed. Same model, same prompt, with and without the skill.
We need the concrete example walkthrough file for Rust testing. Which examples file in the extensions directory should we open?

The instructions your model reads when the skill loads.
This skill provides access to language-specific guidance files used by the code-testing pipeline. Call this skill to get the file paths, then read the relevant file for your target language.

| extensions/powershell.md | PowerShell | Test commands (Pester v5), module import patterns, discovery/run pitfalls, mocking, common errors |
| extensions/cpp.md | C++ | Testing internals with friend declarations |
| extensions/go.md | Go | go test commands, table-driven tests, integration vs unit layout, mocking via interfaces, common errors |
| extensions/java.md | Java | Maven/Gradle commands, JUnit 4/5 and TestNG detection, Mockito, Spring Boot slices, common errors |
| extensions/rust.md | Rust | cargo test commands, unit vs integration vs doc tests, features, async test harnesses, common errors |
| extensions/ruby.md | Ruby | RSpec and Minitest commands, Bundler usage, Rails specifics, mocking patterns, common errors |

| extensions/kotlin.md | Kotlin | Gradle commands, JUnit/Kotest detection, MockK, coroutines test, KMP and Android specifics, common errors |
| extensions/dotnet-examples.md | .NET (C#/F#/VB) | Concrete pipeline examples: sample research output, plan, generated tests, fix cycles, final report |
| extensions/python-examples.md | Python | Concrete pipeline examples (pytest): research, plan, generated test file, fix cycles, final report |
| extensions/typescript-examples.md | TypeScript/JavaScript | Concrete pipeline examples (Vitest, applicable to Jest): research, plan, generated test file, fix cycles, final report |
| extensions/go-examples.md | Go | Concrete pipeline examples (standard testing): research, plan, table-driven test file, fix cycles, final report |
| extensions/java-examples.md | Java | Concrete pipeline examples (JUnit 5 + Mockito on Maven): research, plan, generated test file, fix cycles, final report |
Read the appropriate extension file for the target language before writing test code. When an <language>-examples.md file exists for the target language, read it alongside the base extension to see a concrete end-to-end pipeline walkthrough (research output, plan, generated tests, fix cycles, final report).
