Install sdd for Codex and Claude Code

Installs for the current user

codex plugin marketplace add YMD7/agent-plugins
codex plugin marketplace upgrade agent-plugins
codex plugin add sdd@agent-plugins

Paste and run these commands in a terminal with Codex. They add and refresh the agent-plugins catalog, then install this plugin.

Compatibility: the page URL and API slug “sdd-3” remain stable.

Codex: sdd-3@agent-plugin-marketplace → sdd@agent-plugins

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.
