What problem does it solve? Creating a new Codex plugin requires a specific directory structure, a correctly shaped .codex-plugin/plugin.json manifest, and optionally a marketplace entry with valid policy fields. Doing this by hand is error-prone and repetitive. ## Core Features & Use Cases - Plugin Scaffolding: Generates a normalized plugin folder with a complete placeholder plugin.json including the full interface section. - Optional Structure: Adds skills/, hooks/, scripts/, assets/, .mcp.json, and .app.json on demand via CLI flags. - Marketplace Management: Creates or updates .agents/plugins/marketplace.json entries with required policy.installation, policy.authentication, and category fields, supporting both repo-local and home-local plugins. - Use Case: You want to publish a new local plugin called "My Reports". Run the scaffold script to get plugins/my-reports/.codex-plugin/plugin.json with placeholders, then add --with-marketplace to register it in the marketplace ordering. ## Quick Start Ask the assistant to scaffold a new Codex plugin named my-plugin with a marketplace entry using the plugin-creator skill.
