Use when a PR/MR explanation was just delivered (e.g. right after the explain-pr skill finishes) and the change was substantially agent-written, or whenever the user asks to be quizzed on a change: 'quiz me on this change', 'tomame el quiz', 'quiz del MR', 'tomame la lección', '/pr-quiz'. Counters comprehension debt: a formative, change-specific check that the user can defend code they delegated to a coding agent. Do NOT use for code review, bug hunting, or explaining changes…
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
# MR Quiz — can you defend this change? The user just shipped a change that an agent largely wrote. The explanation (`explain-pr`) told them what/why/how; this quiz makes **the user** articulate it. It applies active retrieval with code-grounded feedback — mechanisms with support in adjacent settings (e.g. Anthropic's skill-formation RCT); whether it works here is measured by the user's own delayed performance in study sessions, not assumed. **This quiz is formative and change-specific.** It happens minutes after an explanation, so it measures primed recall. It can catch false confidence and open gaps; it can NEVER certify a subsystem, advance a spacing interval, or close a durable gap (closing requires cold or delayed evidence from a study session). **The user answers. You grade. Never the other way around.** ## The quiz contract 1. **Ground yourself in the real diff.** Same range as explain-pr (`git diff <base>...HEAD`). Note `repo@sha` and the paths touched. …

How to install
mdr add mryll/skills/pr-quiz@sha256:8048a84f3d4df953The line at the top of this page pins the label v2.0.0, 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.
