Each skill is a standalone Agent Skills spec (opens in a new tab) directory with a SKILL.md file. To use them on other platforms, copy the skill directory you want into your platform’s skills location (typically .agents/skills/):
plugins/<plugin>/skills/<skill-name>/ # copy this directory
For example, to add svg-design to a Codex project:
MIT — the text of every skill is reproduced unmodified, frontmatter included, under the upstream licence.
Discovery
3 skills found by walking the repository tree for SKILL.md, not by matching a directory convention. 3 distinct layouts observed: plugins/openchart/skills/*/SKILL.md, plugins/opendata/skills/*/SKILL.md, plugins/opendesign/skills/*/SKILL.md.
Issue colours
Resolved from a deterministic hash of the owner name. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.
Heading repairs
1 repair applied to the front matter so the document has one h1 and no skipped levels:
Shifted “8 headings” from h1 to h2 so the skill title is the only h1.
Images inside a skill come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.
Marketplace
A plugin manifest is published at .claude-plugin/marketplace.json by OpenData, declaring 3 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.
Signal
This repository is unranked on skills.sh, which says nothing about it: the leaderboard covers a fraction of published skills.
Agent surfaces
The whole issue is available as one markdown document at /tryopendata/skills.md, and each skill at its own .md URL.
Publication
Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
