miri-scout skillA

miri-scout is agent-read markdown (skill) from miri-lang/miri: Scout 🔎 — a quality-focused single pass that hunts down ONE real bug in the Miri compiler/runtime and fixes it at the root. Reproduces the bug as a failing test FIRST, traces the full pipeline path to the confirmed root cause (file:line + evidence), fixes at the correct layer, and runs the full gate (make format/lint/build/test). Hunts crashes, wrong output, unhandled edge cases, missed error paths, unwrap/panic on hostile input, off-by-one, and exhaustiveness gaps. Reads and appends critical l.

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.
