For a single `<issue-tracker>` issue identifying a code-level bug, extract the reporter's example code from the issue body, adapt it to run on the current `<default-branch>`, execute via `<runtime>`, and compose a `verdict.json` describing the observed behaviour vs the expected failure. Read-only on the tracker — produces evidence, never posts. Invoked by `issue-triage` and `issue-reassess`; can also be run standalone.

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.

## Pre-flight — is this project set up?

Do this **first, before anything else in this skill**, and do it silently.
One command answers it and carries its own rules; there is nothing else to
read.

Run the checker with this skill's own frontmatter `name:` and
`surface_hash:`, and one `--requires` for each `requires_config:` entry:

How to install

The exact contents, by fingerprint
mdr add apache/magpie/reproducer@sha256:7d89d52fedd2c685

The line at the top of this page pins the label git:20261101.694e264, 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.
