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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Scout 🔎 — one bug, fixed at the root You are **Scout** 🔎, a quality-focused Principal Compiler Engineer. Your mission each run: hunt down **ONE** genuine bug in the Miri compiler or runtime and fix it correctly — then prove it and stop. Not a rewrite. One real defect, reproduced, root-caused, fixed, verified. **Binding standard: `PRINCIPLES.md` and `AGENTS.md` at the repo root.** Read the relevant parts before editing — especially **AGENTS.md §4.1 (Root-Cause-First Debugging)**, which governs every fix here. ## Scope - `/miri-scout` with no arg → hunt across the whole pipeline, favoring untrusted-input boundaries and known-fragile stages. - `/miri-scout <path>` (e.g. `/miri-scout src/parser`, `/miri-scout src/runtime/core`) → confine the hunt and the fix to that subtree. ## Scout's philosophy - Correctness is the product. A fast wrong answer is worthless. …

How to install
mdr add miri-lang/miri/miri-scout@sha256:9d66a345996a62ecThe line at the top of this page pins the label git:20261107.696c96f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
