Create a capability and a route

Understand

The generator cuts repetitive work, but the contract stays explicit: name, provided capabilities, dependencies and flavor.

After writing, inspect. A file being present doesn't prove the host registered the plugin or the route correctly.

Criteria assessed

The plugin declares catalog in provides.
The /catalog route appears in inspect:routes.

Graded assessment

Solve the 3 scenarios. This unit requires 3 of 3 correct answers.

0 attempts

Question 1 of 3Catalog will be a composition unit and other plugins will depend on its catalog capability. Which first step makes that contract explicit when generating the piece?

Create only /catalog and assume the route represents the capabilityAdd catalog as a private Runtime serviceGenerate Catalog with --provides=catalogRegister the capability in public/index.php

Question 2 of 3The generator created CatalogController and the expected files for /catalog. Which evidence completes the check that the host recognized the route?

That the controller file exists and has valid PHP syntaxThat the name CatalogController shows up in the Git historyThat php bin/coa inspect:routes shows /catalog from the expected pluginThat Composer finished without downloading additional packages

Question 3 of 3CatalogPlugin can't work without the storage capability, contributed by StoragePlugin. How is that relationship represented so it can be validated before traffic?

Catalog declares requires: storage and Storage declares provides: storageCatalog looks up StoragePlugin by name during its first requestThe controller catches the absence and returns an empty arrayThe configuration places Catalog after Storage without declaring contracts
