For AI Agents

Agent-friendly by design

Drop OpenTypes into your AI workflow

Every resource an agent needs is published as clean Markdown at a stable URL — no scraping, no JavaScript, no wasted tokens. Start with SKILL.md — a portable Agent Skills file with frontmatter that any skill-aware client (Claude Code, Codex CLI, Cursor) can consume.

Open SKILL.md

SKILL.md/SKILL.md
Agent Skills spec with frontmatter — drop into Claude Code, Codex, Cursor, or any skill-aware client to teach an agent when and how to install OpenTypes.
llms.txt/llms.txt
Curated index of every schema with descriptions, install commands, and links — follows the llmstxt.org spec.
llms-full.txt/llms-full.txt
Full agent reference: every schema, its dependencies, and the complete TypeScript + Zod source in one Markdown file.
Per-type Markdown/types/<name>.md
Clean Markdown version of every type detail page — token-efficient, no styling, ready to drop into an agent context.

One-liner for an agent

# 2. Or hand it the curated index

# 3. Install a schema (with Zod v4 validators)
