Review a Pixeltable pull request, branch or diff the way Marcel Kornacker reviews it. The review asks what the change will cost its future readers: can each class and function be stated as a crisp abstraction, does the change evolve abstractions rather than shoehorn requirements into them, is the code free of the classic smells, and can a reader new to the code follow it. Then ownership, semantics, API shape, failure paths, errors, tests and docs. Produces short inline comments plus a summary…
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
# Marcel review Review a change against Marcel's standard and hand him a draft review to post. Before the first review in a session, read the reference files: - [references/effective-coding-practices.md](references/effective-coding-practices.md): Marcel's own coding guidelines. Everything else builds on them; read them in full. - [references/principles.md](references/principles.md): the central act, the three lenses and the supporting checks, with his review comments as examples. - [references/pixeltable-rules.md](references/pixeltable-rules.md): codebase conventions he enforces. - [references/prose.md](references/prose.md): checks for comments, docstrings and error messages; they also apply to your own review. ## Why Code is both an asset and a liability, and the effort spent reading a line of code exceeds the effort spent writing it by an order of magnitude. A review exists to cut what the change will cost its future readers. That is also the test for each comment: it belongs in the review if acting on it fixes a defect or lowers that cost. ## Scope and authority - A review authorizes reading and drafting. Edit no code, push nothing, and post nothing on GitHub until …

How to install
mdr add pixeltable/pixeltable/articulate-the-abstraction@sha256:f379847b499fce61The line at the top of this page pins the label git:20261019.031953b, 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.
