Graph-informed mutation testing triage. Parses codebases with Trailmark, runs mutation testing and necessist, then uses survived mutants, unnecessary test statements, and call graph data to identify false positives, missing test coverage, and fuzzing targets. Use when triaging survived mutants, analyzing mutation testing results, identifying test gaps, finding fuzzing targets from weak tests, running mutation frameworks (including circomvent and cairo-mutants), or using necessist.

# Genotoxic Combines mutation testing and necessist (test statement removal) with code graph analysis to triage findings into actionable categories: false positives, missing unit tests, and fuzzing targets. ## When to Use - After mutation testing reveals survived mutants that need triage - Identifying where unit tests would have the highest impact - Finding functions that need fuzz harnesses instead of unit tests - Prioritizing test improvements using data flow context - Filtering out harmless mutants from actionable ones - Finding unnecessary test statements that indicate weak assertions (necessist) ## When NOT to Use - Codebase has no existing test suite (write tests first) - Pure documentation or configuration changes - Single-file scripts with trivial logic ## Prerequisites - **trailmark** installed — if `uv run trailmark` fails, run: ```bash uv pip install trailmark ``` **DO NOT** fall back to "manual verification" or "manual analysis" as a substitute for running trailmark. Install it first. If installation fails, report the error instead of switching to manual analysis. - A **mutation testing framework** for the target language — if the framework command fails (not found, not installed), install it using the instructions in [references/mutation-frameworks.md](references/mutation-frameworks.md). **DO NOT** fall back to "manual mutation analysis" or skip mutation testing. Install the framework first. If installation fails, report the error ins
