One-command scaffolding from the 18 published @metaharness/* example packages — the fastest path from a use-case to a working harness, no template/host flags to remember.
Where create-harness walks the full wizard, this skill maps a use-case straight onto a published npm wrapper. Each wrapper shells out to metaharness@latest with the correct --template + --host flags, so the result is byte-identical to the full CLI invocation.
bashmkdir -p ~/.codex/skills/example-harness curl -fsSL https://raw.githubusercontent.com/ruvnet/agent-harness-generator/main/.codex/skills/example-harness/skill.toml \ -o ~/.codex/skills/example-harness/skill.toml
No MCP server needed — the wrapper packages run via npx.
/example-harnessCodex prompts for the package + a directory name, then runs:
bashnpx --yes @metaharness/<package>@latest <name>

Every scaffold ships a .claude-plugin/plugin.json, so it also loads as a Claude Code plugin: claude -p --plugin-dir <name> "...".
