Concrete CMS packages are modular components that extend the functionality of the platform. This skill is essential for developers who want to create custom functionality or integrate third-party services into their Concrete CMS projects.
Follow these steps to develop a custom package in Concrete CMS:
packages/ with a lowercase, underscore-separated name (e.g., packages/my_custom_package).controller.php file in the package root. Define the package handle, version, and basic information.
install() method of your controller, add code to register block types, themes, single pages, or other entities.

Apply this skill whenever you are writing, reviewing, or modifying PHP code for Concrete CMS (concrete5) — custom blocks, packages, single pages, dashboard or dialog or backend controllers, REST endpoints, Express entities, themes, attribute types, jobs, or anything in concrete/controllers, concrete/blocks, controllers/, blocks/, packages/, src/. Use it even when the user does not say "security" — for example, adding a new endpoint, accepting a POST parameter, rendering a user-supplied string, unserializing block config, fetching a URL server-side, or handling a file upload. Concrete CMS shipped 90+ CVEs over the past four years and the failure modes repeat — admin strings rendered raw, missing CSRF tokens on state-changing GETs, unserialize() on stored data, file uploads validated after writing, sequential IDs without per-object authz, type-juggling guard bypasses, OAuth handlers that skip account-state checks. This skill encodes the patterns behind those CVEs so you do not reproduce them.
Create and manage Concrete CMS block types. Use this skill when the user asks to create or modify custom block types.
This skill provides instructions and best practices for creating and managing single pages in Concrete CMS packages. Use this skill when you need to add custom dashboard pages, specific application logic pages, or any landing pages that don't follow the standard page type/template system.
Customize the appearance of Express forms in Concrete CMS
This skill provides guidance and standard workflows for developing custom themes for Concrete CMS, including directory structure, page templates, asset management, and v9+ features like containers. Use this when creating or modifying Concrete CMS themes.
