Merge changes down the release branch chain (master → 9.0 → 9.1 → … → 9.X). Resolves merge conflicts, pushes to the correct remote per branch. Use when the user wants to cascade/propagate changes from master through all minor release branches (e.g., "merge cascade", "propagate master", "cascade merge", "/merge-cascade").

Run an automated code review of unstaged changes using Codex CLI, then fix issues and re-review in a loop until approved. Use when the user asks to review changes with Codex, run a code review cycle, or invokes /codex-code-review.

Update all dependencies to latest minor versions across the Mantine monorepo, validate, test, build, and generate a report. Use when the user wants to update dependencies, upgrade packages, run dependency maintenance, or asks to "update deps", "upgrade dependencies", "dependency update", "/update-dependencies".

Initialize a new Mantine minor or major release: creates a git branch, sets up the changelog MDX page, updates mdx-meta-data.ts, mdx-nav-data.ts, and versions.ts, and commits. Use when the user wants to start a new release (e.g., "new release 9.1.0", "/new-mantine-release 9.1.0", "initialize 9.2.0 release").

Sync Mantine GitHub releases into packages/@mantinex/mantine-meta/src/versions.ts. Use when the user wants to update the versions list, sync release dates, add missing patch versions, or update changelog links for older major versions. Triggers on requests like "sync versions", "update versions.ts", "add missing releases".

Build custom dropdown/select/autocomplete/multiselect components using Mantine's Combobox primitives. Use this skill when: (1) creating a new custom select-like component with Combobox primitives, (2) building a searchable dropdown, (3) implementing a multi-select or tags input variant, (4) customizing option rendering, (5) adding custom filtering logic, or (6) any task involving useCombobox, Combobox.Target, Combobox.Option, or Combobox.Dropdown.

Build custom components that integrate with Mantine's theming, Styles API, and core features. Use this skill when: (1) creating a new component using factory(), polymorphicFactory(), or genericFactory(), (2) adding Styles API support (classNames, styles, vars, unstyled), (3) implementing CSS variables via createVarsResolver, (4) building compound components with sub-components and shared context, (5) registering a component with MantineProvider via Component.extend(), or (6) any task involving Factory, useProps, useStyles, BoxProps, StylesApiProps, or ElementProps in @mantine/core.

Build forms using @mantine/form in the mantine-9 repository. Use this skill when: (1) setting up a form with useForm, (2) adding validation rules or async validation, (3) working with nested object or array fields, (4) sharing form state across components with createFormContext, (5) using uncontrolled mode for performance, (6) using the standalone useField hook, or (7) any task involving useForm, getInputProps, onSubmit, insertListItem, or form validation.
