About this skill

What it does. Parses a repository without building or running tests, using Roslyn for C#/.NET or tree-sitter for supported languages. It reports paired and unpaired source files, declaration counts, suggested test paths and, for polyglot scans, orphan tests.

When to use it. Use it to create a static source-to-test worklist before writing tests or to check newly generated tests. It does not measure line or branch coverage, prioritise from coverage data, or assess test strength; treat results as heuristic.
