What problem does it solve?

This Skill allows developers to extend existing Open Mercato modules without modifying their source code, enabling customization and integration.

Core Features & Use Cases

  • Modular Extension: Add fields, columns, filters, actions, menu items, and more to existing entities.
  • API Interception & Mutation Guards: Intercept API requests and validate/transform mutations before persistence.
  • Component Replacement: Swap or wrap UI components to customize the user interface.
  • Event Handling: React to domain events emitted by other modules.
  • Use Case: A team needs to add a custom "priority" field to the existing "Customer" form and display it as a column in the "Customers" table. This Skill guides them through creating a response enricher, a field widget, and a column widget, and wiring them together using the Triad Pattern.

Quick Start

Use the system-extension skill to add a new column to the 'customers.person' table.
