yuiseki-open-data SKILL.md skillA
yuiseki-open-data from yuiseki/map-from-scratch is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Catalog of the geospatial data the owner publishes on z.yuiseki.net/static and on Hugging Face (yuiseki/*), with format, layout, size, licence, local path, public URL and how well each reads by HTTP Range as is. Load it when choosing data for a new map-from-scratch request ("I want to ..., so make me a map"), before writing spec.yaml datasets or bake.ts, or when asked what data is available for a renderer.
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
# yuiseki-open-data: what data there is, and how it reads The owner keeps two public shelves of data. Most of what a map-from-scratch request needs is already on one of them, in a layout chosen for HTTP Range reading. This skill says what is there, where the bytes are on this machine, the public URL, the licence, and whether a renderer can read it as is or must bake it first. - One section per dataset: [references/catalog.md](references/catalog.md). - Surveyed 2026-10-26 from the local copies (`/sata_hdd_24tb/www/html/static/` and `/sata_hdd_24tb/hf_data/`), the Hugging Face API (96 datasets) and the files' own headers (PMTiles header and metadata, Parquet footers through DuckDB 1.5.5 in `mfs-base`, SQLite pragmas). Counts below are measured, not copied from READMEs, unless marked. ## How to use it 1. Read the request for: area, time span, what is drawn (points, lines, polygons, grid, raster), what the user touches (time slider, hover, tap), and the device. Then scan the overview table below for area and kind. 2. Open the dataset's section in references/catalog.md. Check the licence first: Ookla is CC BY-NC-SA, ekidata.jp forbids paid redistribution of …

How to install
mdr add yuiseki/map-from-scratch/yuiseki-open-data@sha256:5ae0739a9620343eThe line at the top of this page pins the label git:20261026.85ca76d, 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.
