test-impact skillA

test-impact is agent-read markdown (skill) from borda/ai-rig: Identify which tests need rerunning after a code change — traces static call graph (function-level) or import graph (module-level) to find affected test files, then emits a ready-to-run pytest command. TRIGGER when: user asks which tests are affected by a change; phrases: "which tests are affected", "what tests cover this", "test impact of", "what tests to rerun"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add borda/ai-rig/test-impact@git:20260918.49b4239
Exact content
mdr add borda/ai-rig/test-impact@sha256:18b9960cfd078c25

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
