Quality

Content

37%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This skill is concise and well-structured at a high level, but critically lacks actionability—there are zero code examples for a code-centric testing skill. The content reads more like a checklist of tools and conventions than an instructional guide Claude can follow to produce correct test files. The referenced implementation.md file is not provided, so the skill's usefulness depends entirely on content that cannot be evaluated.

Suggestions

Add concrete, executable code examples for each test type (e.g., a ViewModel unit test with MockK and runTest, a Compose UI test with HiltAndroidRule and createAndroidComposeRule).

Include a step-by-step workflow for writing a test: e.g., 1) Create test class with annotations, 2) Set up rules, 3) Mock dependencies, 4) Write test body, 5) Run and verify.

Provide the referenced 'references/implementation.md' file or inline its key content (like MainDispatcherRule implementation and @TestInstallIn module patterns) so the skill is self-contained.

Add a concrete example of the anti-patterns and their correct alternatives (e.g., show Thread.sleep replaced with waitUntil).

DimensionReasoningScore

Conciseness

The content is lean and efficient. It avoids explaining what unit tests, MockK, or Hilt are, and assumes Claude's competence with Android testing concepts. Every line adds specific, non-obvious guidance.

3 / 3

Actionability

The skill provides no executable code examples, no concrete test snippets, and no copy-paste ready patterns. It describes what to use (e.g., 'Use MockK', 'Use runTest') but never shows how with actual code, making it vague direction rather than concrete guidance.

1 / 3

Workflow Clarity

There is no sequenced workflow for writing tests. The content lists tools and anti-patterns but doesn't describe a step-by-step process for creating a test file, setting up test infrastructure, or validating test correctness.

1 / 3

Progressive Disclosure

The skill references 'references/implementation.md' for test rules, which is a good signal of progressive disclosure. However, the bundle has no files, so the reference is unverifiable, and the main content is thin enough that it's unclear what value the reference file adds versus just including the content inline.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a strong skill description that clearly defines its scope (Android testing), lists specific concrete actions and technologies, and includes an explicit 'Use when' clause with natural trigger terms. It uses proper third-person voice and is concise without being vague, making it easy for Claude to distinguish from other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'Write unit tests', 'Compose UI tests', 'Hilt-integrated tests' along with specific targets like 'ViewModels, Composables, or Repositories' and tools like 'MockK and coroutine test utilities'.

3 / 3

Completeness

Clearly answers both what ('Write unit tests, Compose UI tests, and Hilt-integrated tests for Android') and when ('Use when writing test files or testing ViewModels, Composables, or Repositories with MockK and coroutine test utilities') with explicit trigger guidance.

3 / 3

Trigger Term Quality

Includes strong natural keywords users would say: 'unit tests', 'UI tests', 'Hilt', 'Android', 'ViewModels', 'Composables', 'Repositories', 'MockK', 'coroutine test', 'test files'. These cover a wide range of terms a developer would naturally use.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive with a clear niche: Android testing specifically with Compose, Hilt, MockK, and coroutine utilities. Unlikely to conflict with general testing skills or non-Android skills due to the specific technology stack mentioned.
