Creating a Backstage Scaffolder Action

When to use this skill

• Building a custom action that scaffolder templates can call (e.g. acme:user:create, myorg:slack:notify)
• Editing an existing scaffolder-backend-module-* plugin

What you build

A scaffolder action is a backend module (createBackendModule({ pluginId: 'scaffolder', ... })) that registers a TemplateAction against the scaffolderActionsExtensionPoint. Two pieces:

1. The action itself (created via createTemplateAction)
2. The module that registers it
