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: Read the caller-provided or runtime-listed test-analysis-extensions catalog, then its matching language file (dotnet.md, python.md, typescript.md, go.md, etc.). test-analysis-extensions is reference-only; do not invoke it as a skill. If the bundle is absent, use the pinned framework and this skill's rules, report the missing reference, and do not search installation directories.

Why Assertion Diversity Matters

Low assertion diversity signals shallow testing. Tests may pass while bugs hide in unasserted logic. Common symptoms:
