Artifact Creator

Create the smallest complete artifact that satisfies the user's requested runtime and security boundary. Keep portable instructions separate from host packaging.

Overview

There is one portable Agent Skills contract, one open MCP protocol, and many different plugin, agent, hook, permission, and marketplace formats. This skill selects the correct authority before writing files and prevents host-specific details from leaking into the portable core.

When to use

Use for a new or substantially revised skill, subagent, plugin, MCP integration, hook, or marketplace entry. For a production modernization involving research, migration, security review, and release evidence, use production-upgrade instead. For review without changes, use artifact-validator.
