antialiasing-and-blending from yuiseki/map-from-scratch is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

How map engines smooth edges (MSAA, analytic coverage in the shader, post-process, none), pay for resolution, blend translucent layers without darkened overlaps, keep one alpha convention, and avoid seams between tiles and shapes, with what each choice cost them. Load it when a map-from-scratch request has translucent fills or lines, layer opacity, fades, thin strokes or points on a target without MSAA (offscreen framebuffer, WebGPU, another engine's context, Canvas 2D hit canvas), a…
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
# Antialiasing and blending: edges, alpha, overlaps and seams Every map edge is a partial-coverage problem, and every partial-coverage pixel is a blending problem. A general engine must antialias any shape on any render target, blend any number of translucent layers in any order, composite over any page, and accept tiles from any producer, so it carries MSAA, shader coverage, offscreen passes, stencil tricks and alpha bookkeeping, and still ships bugs where two of them meet: darker overlaps, fringes at transparent edges, hairline seams between tiles, ids that do not exist. A renderer made for one request knows its targets, its layers and whether any of them is translucent, so most of this machinery becomes a bake-time decision or disappears. This skill collects what the engines decided and why. Line geometry (joins, the ±0.5 px outset) is in the line-tessellation skill, glyph halos in text-rendering, icon snapping in symbols-and-icons, fallback tiles in tile-lod-and-overzoom; only the coverage and blending side is here [108]. Per-engine detail is in [references/engines.md](references/engines.md). ## First decision: where does edge coverage come from? …

How to install
mdr add yuiseki/map-from-scratch/antialiasing-and-blending@sha256:f4d7cec8a350341cThe line at the top of this page pins the label git:20261026.79a684e, 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.
