Create skills that help people and AI agents accomplish goals with z-schema — a JSON Schema validator supporting draft-04 through draft-2020-12.
Skills live in skills/ / and teach Claude how to perform z-schema tasks reliably: validating data, writing schemas, handling errors, using custom formats, contributing to the codebase, and more.
Match your communication style to the user's technical level. Most z-schema users are developers, but skill creation itself may be new to them. Briefly explain skill-specific concepts (frontmatter, progressive disclosure, trigger descriptions) when first introduced. Don't assume everyone knows what YAML frontmatter is — one sentence of explanation is enough.
Create, improve, and test skills for the z-schema JSON Schema validator library. Use this skill whenever the user wants to create a new skill from scratch, turn a workflow into a reusable skill, update or refine an existing skill, write test cases for a skill, or organize reference material for a skill. Also use when someone mentions "skill", "SKILL.md", or wants to document a z-schema workflow for reuse by humans or AI agents. Source: zaggino/z-schema.
