assertion-quality Skill
Analyzes the variety and depth of assertions across test suites in any language. Use when the user asks to evaluate assertion quality, find shallow testing, identify assertion-free tests (no assertions or only trivial ones like Assert.IsNotNull / expect(x).toBeTruthy() / assert x is not None), flag self-referential or Published by microsoft in testfx.

Skill instructions
Assertion Diversity Analysis Analyze test code in any supported language to measure how varied and meaningful the assertions are. Produce a metrics report that reveals whether tests verify different facets of correctness — not just "output equals X" but also structure, exceptions, state transitions, side effects, and invariants. Language-specific guidance: Call the test-analysis-extensions skill to discover available extension files, then read the file matching the target codebase's language and framework (e.g., dotnet.md for .NET, python.md for pytest, typescript.md for Jest, go.md for the standard testing package). You MUST read the relevant extension file before classifying assertions, because assertion APIs differ significantly across frameworks. Why Assertion Diversity Matters Low assertion diversity signals shallow testing. Tests may pass while bugs hide in unasserted logic. Common symptoms: | Problem | Symptom | Consequence | |---------|---------|-------------| | Trivial asserti
