jsonapi4j — Claude Code plugin

A Claude Code plugin that teaches AI agents how to build apps with the jsonapi4j framework (pro.api4). It bundles the jsonapi4j skill: resources, to-one/to-many relationships, operations, compound documents/includes, pagination, validation, access control, configuration, and RestAssured testing.

It auto-activates whenever you work in a codebase that depends on jsonapi4j (imports under pro.api4.jsonapi4j, the @JsonApiResource / @JsonApiRelationship / @JsonApiResourceOperation annotations, or a /jsonapi rootPath).

This is for developers building on jsonapi4j. If you're contributing to the framework itself, see the repo's AGENTS.md instead.

Install

From any project that uses jsonapi4j:

/plugin marketplace add MoonWorm/jsonapi4j
/plugin install jsonapi4j@jsonapi4j

(The first command registers this repo as a plugin marketplace; the second installs the plugin from it.)
