SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Command handlers in aibdd workflows often struggle with consistent service invocation, error handling, and dependency resolution. This Skill provides a structured reference for implementing reliable Command handlers that execute operations via service methods, capture failures, and enforce proper layer boundaries.

Core Features & Use Cases

  • Deterministic service invocation: invoke the correct service method based on the api.yml operationId to execute business logic.
  • Error containment: When steps are executed, failures are caught and stored for later validation, avoiding leakage into the test flow.
  • Dependency-driven IDs: all necessary identifiers are sourced from a shared ids map, preventing hard-coded lookups.
  • No direct DB access: reinforces service-layer boundaries, disallowing direct DB calls from the command handler.

Quick Start

Provide a concrete example that uses a When step to call a service method and handle errors with try/catch.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I handle errors in PHP command handlers without breaking the test flow?▼

Error handling in PHP command handlers captures failures via a lastError mechanism, storing errors for later validation. Wrapping service method calls in try/catch blocks contains exceptions so they do not leak into the test flow.

What's the best way to resolve dependencies in WordPress service layer command handlers?▼

Dependency resolution in WordPress command handlers uses a shared ids map. Sourcing all necessary identifiers from this map prevents hard-coded lookups and ensures deterministic service invocation when executing business logic.

How do I invoke service methods deterministically from PHP command handlers?▼

Deterministic service invocation in PHP command handlers uses the operationId defined in api.yml. This ensures the correct service method is called to execute business logic while enforcing service-layer boundaries.

Why should PHP command handlers avoid direct database access in integration tests?▼

Direct database access in PHP command handlers breaks service-layer boundaries. Preventing direct DB calls ensures all state-changing operations route through service methods, maintaining consistent error handling and architectural integrity.

Can I use Given and When steps to test state-changing operations in WordPress?▼

Given and When steps in WordPress execute state-changing operations by invoking service methods. The When step calls the appropriate service method while the command handler captures any failures through the lastError mechanism for validation.
