Scaffolding a Claude Code and Codex plugin repository requires generating the necessary `.claude-plugin/` and `.codex-plugin/` manifests. This process creates a complete, marketplace-ready GitHub repo structure with correct autodiscovery and schema constraints.

Publishing a Claude Code plugin to the marketplace requires `plugin.json` and `marketplace.json` files. These metadata files ensure your plugin can be correctly discovered, installed via the marketplace flow, and validated against required schema constraints.

Packaging existing skills and agents into a unified plugin requires keeping them at the repository root so autodiscovery works properly. Scaffolding tools enforce this correct repo structure while generating the necessary plugin manifests.

Configuring MCP servers and hooks is supported when creating a plugin repo. During the scaffolding process, you can select optional skills, agents, hooks, and MCP server configurations to include in your generated plugin manifests.

Claude Code plugin schema validation fails during marketplace installation when repository structure is misconfigured. If skills and agents are not placed at the repo root, autodiscovery breaks, preventing correct operation and marketplace metadata processing.

Scaffolding a marketplace-ready plugin requires providing your repo name, GitHub username, a one-sentence description, author name, the plugin contents, and your chosen license. This information populates the generated manifest and marketplace metadata files.
