Bump the Umbraco CMS version across all required files. Use when the user asks to bump, update, or set the version number — e.g., "bump version to 17.3.4", "set version to 18.0.0-rc", "update version". Accepts the target version as an argument.

umb-review

Automated PR code review for Umbraco CMS. Analyzes changed files for intent, impact on consumers, breaking changes, architecture compliance, and code quality. Non-interactive — outputs a full structured review. Use this skill whenever the user asks to review a branch, review a PR, check their changes for issues, analyze a diff, or validate breaking change patterns — even if they don't say "review" explicitly. Does NOT apply to writing new code, fixing bugs, refactoring, explaining architecture, writing tests, or reviewing documentation content.

umb-release-notes

Improve a set of auto-generated GitHub release notes for an Umbraco CMS release. Cross-checks the notes against every PR carrying the release label, adds any that are missing, re-files every PR under the most appropriate category, and strips purely-internal entries. Use whenever the user asks to tidy up, improve, complete, or recategorize release notes for a given version, or mentions a release-notes text file plus a version number.

general-create-workspace

Create a new workspace for an entity in the Umbraco backoffice. Supports two workspace types — default (simple, manifest-only, for root/listing pages) and routable (entity detail editing with create/edit flows). Use when the user says "create a workspace", "add a workspace for X", or "scaffold a workspace". For routable workspaces, the entity must already have a package, entity type, repository, and data source.

general-deprecate-api

Deprecate a public API (class, method, property, type, constant, or context token) following the 2-major-version rule. Use when removing or replacing any publicly exported symbol that external consumers may depend on — includes exports from package index.ts files, global components, extension type aliases, and manifest schemas.

general-create-repository

Create or extend a repository in the Umbraco backoffice. Covers detail (CRUD), item (batch lookup), collection (paginated list), and action-specific (publish, duplicate, move, etc.) repositories. Use when the user says "create a repository", "add a data source", or when a feature needs to fetch or post data. Each repository type has its own template — pick the right one based on the operation.

general-create-package

Create a new package in the Umbraco backoffice client with its first module. Use when adding a new domain feature area that needs its own package under src/packages/ — e.g., a new CMS feature like data types, tags, or relations. Packages are self-contained domain modules that can theoretically be uninstalled independently. Also use when the user says things like "scaffold a new package", "add a new feature package", or "create a new domain module".

general-create-kind

Create a new extension kind — a reusable default implementation for an extension type. Use when multiple extensions of the same type share the same element/API implementation and only differ in configuration. Kinds reduce boilerplate by providing pre-built defaults that extensions customize via meta.

general-create-extension-type

Create a new extension type for the Umbraco backoffice extension registry. Use when adding a new type of extension that can be registered via manifests (e.g., a new dashboard type, a new sidebar app type, a new toolbar extension type). Any package can define extension types.

general-create-condition

Create a new extension condition that controls when extensions are active. Use when you need to conditionally show or hide extensions based on application state (e.g., current section, user permissions, entity state, workspace context). Conditions are registered as extensions and referenced in manifest condition arrays.

general-add-value-type

Add a new value type — a named, typed string constant that extends UmbValueTypeMap. Use when a feature needs to declare what type of value it holds so it can be referenced in collection columns or value summary manifests. Also use when a property editor needs to expose its value type for use in collection views.

general-add-value-summary

Add a value summary extension so a feature's typed value can be displayed compactly in collection views (e.g., table columns). Use when a feature or property editor already has a value type and needs a renderer for collection table cells. Two variants — simple (element only, no API call) and resolver (batch API resolution needed). Prerequisite: a value type constant must already exist — use the general-add-value-type skill first if it doesn't.
