Agents

Help Claude Code, Codex, Cursor and other coding agents write ArkType

Skill

The ArkType skill tells agents when to reach for ArkType, how its syntax maps to TypeScript, and which mistakes to avoid. Add it to your project with:

npx skills add arktypeio/arktype

Releases after 2.2.8 also include the skill in the arktype package at skills/arktype/SKILL.md, so tools like skills-npm can link the copy that matches your installed version.

Docs as Markdown

Every page of these docs is available as Markdown by adding .md to its URL, e.g. /docs/intro/setup.md. The buttons under each page's title copy it or open it in Claude, ChatGPT or Cursor.

/llms.txt has every ArkType page in one file, in the order of the sidebar. Attest's docs are at /docs/attest/llms.txt.

AGENTS.md

If your project has an AGENTS.md or CLAUDE.md, a line like this keeps agents on ArkType when they add validation:

Validate untrusted input with ArkType. Docs: https://arktype.io/llms.txt
