ZIO Skills — Teach Your Agent to Build ZIO Applications

Teaching coding agents (Claude Code, Cursor, Codex, Gemini, OpenCode) how to build and document ZIO applications.

This marketplace currently ships three plugins:

• zio-skills — Build ZIO and ZIO HTTP applications (server scaffolding, OpenAPI code generation, endpoint API, …).
• documentation — Write high-quality documentation for ZIO libraries (reference pages, how-to guides, tutorials, mdoc conventions, writing-style enforcement).
• docs-write — Guided documentation authoring workflow (research, generation, and quality review for existing code).

Installation

Claude Code

First, add the marketplace, then install one or both plugins:

claude plugin marketplace add zio/zio-skills

# build apps with ZIO / ZIO HTTP
claude plugin install zio-skills@ziogenetics

# write documentation for ZIO libraries
claude plugin install documentation@ziogenetics

# guided documentation authoring workflow
claude plugin install docs-write@ziogenetics

Then invoke a skill in Claude Code:

/zio-http-scaffold
/zio-http-openapi-to-endpoint
/zio-http-endpoint-to-openapi
/zio-http-imperative-to-declarative
/docs-write
/docs-data-type-ref
/docs-how-to-guide
/docs-tutorial
/docs-writing-style
