sanitizer-build-analysis

sanitizer-build-analysis is an Application security skill for AI agents, published by nygenome in the Lancet2 repository on GitHub. Skillspace rates sanitizer-build-analysis C (73/100) and it passed the safety scan; the rating is based on static analysis only.

Use when investigating a crash, intermittent test failure, suspected data race, memory error, or any sanitizer-detectable bug, AND the goal is to land a fix with a regression test. Trigger on "this crashes", "race condition", "use-after-free", "ASan says", "TSan reports", "MSan", "UBSan", "intermittent flake in tests/". Drives pixi-managed sanitizer build trees (cmake-build-asan, cmake-build-msan, cmake-build-tsan, cmake-build-ubsan), reproduces the failure, hands the trace to the sanitizer-expert agent for analysis, and lands the minimum fix with a regression test. Per-sanitizer detail (what each catches, runtime options, common findings, the mimalloc-coverage caveat) lives in references/sanitizer_matrix.md, loaded on demand. For analysis-only of an existing report, use the sanitizer-expert subagent instead.

Unproven: rated by static analysis only, not yet compared head-to-head.

Not launch-quality. It is graded C with a clean safety verdict, but our quality filters exclude it: it looks like a template or a stub that was never filled in; it looks written only for the repository it lives in. So it is not in our launch-quality set, the skills our MCP server searches and recommends. How launch-quality is decided

Our two independent classifiers differ on this skill's category, so treat the placement as provisional.
