Install the Codex plugin

When to use

Install once per Codex environment, then update the marketplace installation when a newer plugin version is published.

Behavior

• The repository marketplace is declared in .agents/plugins/marketplace.json.
• The plugin manifest is plugins/service-architect/.codex-plugin/plugin.json; the MCP process is configured by plugins/service-architect/.mcp.json.
• Codex loads the packaged skills and starts the Python MCP server through the package revision pinned by the plugin.
• Open a new task after installation or update so tool discovery starts with the new plugin definition.
