How to review a map-from-scratch renderer by opening it and looking, because every check can pass on a map that is squashed, upside down or missing half the world; and how to write verification checks against the geography instead of the renderer's own output. Load it before calling a renderer done, when reviewing examples someone else (or another agent) wrote, and when writing verification checks. The mistakes this procedure found, by category (world wrapping, projection, interaction…
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
# Visual review: what only the screen shows Two review passes over the examples (2026-10-30) fixed 19 of them; in 13 the opening view or the first interaction was visibly wrong. `bin/mfs test` caught none of them, and the bench checks could not: they read pixels at places derived from the renderer's own output. This skill is the procedure that found them and the rule for writing checks that would have. What it found, with how to test and fix each mistake, is in `.agents/skills/map-from-scratch/references/rendering-mistakes.md`; read the sections for the request's features before writing the renderer. ## 1. Procedure Do this for every page, in a real browser, at 1920×1021 and at the bench viewport (1280×800). Use the dev server (`bin/mfs serve`) so data under `data/baked` is served. 1. **Look at the opening view before touching it.** Name three features and say where they must be relative to each other (Paris north-west of Cairo, Tokyo east of Osaka, the Bay inside the coast). Check sizes against known ratios: Akita is about 1.6 times taller than wide; Luxembourg must fit an 800 px window at the opening zoom. …

How to install
mdr add yuiseki/map-from-scratch/visual-review@sha256:b1faffe9d36f4492The line at the top of this page pins the label git:20261030.143afe8, 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.
