----
-
-# HA Frontend Components
-
-Use this skill when creating or reviewing Home Assistant UI components and common interaction patterns.
-
-## Dialogs
-
-Open dialogs through the fire-event pattern:
-
-```ts
-fireEvent(this, "show-dialog", {
-  dialogTag: "dialog-example",
-  dialogImport: () => import("./dialog-example"),
-  dialogParams: { title: "Example", data: someData },
-});
-```
-
-Dialog implementation requirements:
-
-- Use `ha-dialog`.
-- Implement `HassDialog<T>`.
-- Use `@state() private _open = false` to control visibility.
-- Set `_open = true` in `showDialog()` and `_open = false` in `closeDialog()`.
-- Return `nothing` while required params are absent.
-- Fire `dialog-closed` in the close handler.
-- Use `header-title` and `header-subtitle` for simple header text.
-- Use slots when standard header attributes are not enough.
-- Use `ha-dialog-footer` with `primaryAction` and `secondaryAction` slots.
-- Add `autofocus` to the first focusable element, such as `<ha-form autofocus>`, and forward it internally if needed.
-
-Use standard dialog widths: `small`, `medium`, `large`, or `full`. Avoid custom dialog sizing unless there is a clear product need.
-
-## Buttons
-
-`ha-button` wraps the Web Awesome button in `src/components/ha-button.ts`.
-
-Axes:
-
-- `variant`: `brand`, `neutral`, `danger`, `warning`, `success`.
-- `appearance`: `accent`, `filled`, `outlined`, `plain`.
-- `size`: `xs`, `s`, `m`, `l`, `xl`.
-
-Common usage:
-
-- Use `appearance="filled"` for primary emphasis when needed.
-- Use `appearance="plain"` for cancel and dismiss actions.
-- Use `variant="danger"` for destructive actions.
-- Place primary actions in `slot="primaryAction"` and secondary actions in `slot="secondaryAction"`.
-
-## Forms
-
-`ha-form` is schema-driven with `HaFormSchema[]` and supports common selectors for entities, devices, areas, targets, numbers, booleans, time, actions, text, objects, selects, icons, media, and location.
-
-Use `computeLabel`, `computeError`, and `computeHelper` for translated labels, validation, and helper text.
-
-```ts
-<ha-form
-  .hass=${this.hass}
-  .data=${this._data}
-  .schema=${this._schema}
-  .error=${this._errors}
-  .computeLabel=${(schema) => this.hass.localize(`ui.panel.${schema.name}`)}
-  @value-changed=${this._valueChanged}
-></ha-form>
-```
-
-## Alerts
-
-Use `ha-alert` for user-visible status messaging.
-
-- Alert types: `error`, `warning`, `info`, `success`.
-- Useful properties: `title`, `alert-type`, `dismissable`, `narrow`.
-- Slots: `icon` for custom leading icon, `action` for custom action content.
-- Content is announced by screen readers when dynamically displayed.
-
-```html
-<ha-alert alert-type="error">Error message</ha-alert>
-<ha-alert alert-type="warning" title="Warning">Description</ha-alert>
-<ha-alert alert-type="success" dismissable>Success message</ha-alert>
-```
-
-## Shortcuts And Tooltips
-
-Use `ShortcutManager` from `src/common/keyboard/shortcuts.ts` for keyboard shortcuts. It blocks shortcuts in input fields, can prevent shortcuts during text selection, and supports character and KeyCode shortcuts for non-latin keyboards. See `src/state/quick-bar-mixin.ts` for global shortcut examples.
-
-Use `ha-tooltip` from `src/components/ha-tooltip.ts` for contextual hover help. See `src/components/ha-label.ts` for an example.
-
-## Panels And Lovelace Cards
-
-Panels commonly extend `SubscribeMixin(LitElement)` and receive route and narrow-layout properties.
-
-Lovelace cards should implement `LovelaceCard`, validate config in `setConfig()`, handle loading, error, unavailable, and missing-entity states, and add a configuration editor when needed.
-
-Cards are user-story surfaces. Support different households, entity types, responsive layouts, and accessible interaction states.

-description: Home Assistant frontend Lit context and hass migration guidance. Use when adding or changing component state access, replacing hass reads, consuming entity or registry contexts, or reviewing rerender behavior.
----
-
-# HA Frontend Contexts
-
-Use this skill when a component reads Home Assistant state, registries, localization, services, config, UI data, connection state, or API helpers.
-
-## Goal
-
-Move leaf components away from the broad `hass: HomeAssistant` object. Broad `hass` access rerenders components for unrelated changes, hides the data a component depends on, and makes tests harder to mock.
-
-Container components may keep `hass` when they own it and feed providers. Leaf components should consume the narrowest context that covers their reads.
-
-## Core Files
-
-- Context definitions: `src/data/context/index.ts`
-- Entity-scoped consume helpers: `src/common/decorators/consume-context-entry.ts`
-- Transform decorator: `src/common/decorators/transform.ts`
-- Canonical migration example: `src/panels/lovelace/cards/hui-button-card.ts`
-- Providers are wired by `contextMixin` on `HassBaseEl`; consumers do not wire providers manually.

-
-Lazy contexts subscribe on first consumer and tear down after the last consumer: `labelsContext`, `fullEntitiesContext`, `configEntriesContext`, and `manifestsContext`.
-
-The single-field contexts such as `localizeContext`, `themesContext`, and `userContext` are deprecated. Use grouped contexts instead.
-
-## Consumption Patterns
-
-Use entity-scoped helpers when the component watches an entity id held on the host:
-
-```ts
-@state() @consumeEntityState({ entityIdPath: ["_config", "entity"] })
-private _stateObj?: HassEntity;
-
-@state() @consumeEntityRegistryEntry({ entityIdPath: ["_config", "entity"] })
-private _entity?: EntityRegistryDisplayEntry;
-
-@state() @consumeLocalize()
-private _localize!: LocalizeFunc;
-```
-
-For a single field from a grouped context, pair `@consume` with `@transform`:
-
-```ts
-@state()
-@consume({ context: uiContext, subscribe: true })
-@transform<HomeAssistantUI, Themes>({ transformer: ({ themes }) => themes })
-private _themes!: Themes;
-```
-
-Use `@transform` with `watch` when the transformer depends on a host property, such as a computed entity id. `consumeEntityState` only watches the first path segment.
-
-To consume a whole group untransformed, omit `@transform` and type the field as `ContextType<typeof statesContext>` or the matching context type.
-
-## Review Checklist
-
-- The component consumes the narrowest context needed for the data it reads.
-- A broad `hass` property is kept only when the component is a container or external API requires it.
-- Entity-scoped reads use the consume helpers rather than ad hoc context transforms.
-- Context fields are marked `@state()` so updates trigger rendering.
-- Tests and mocks only provide the data the component actually consumes.

-
-# HA Frontend Review
-
-Use this skill when reviewing Home Assistant frontend changes or preparing a pull request.
-
-## Pull Request Body
-
-When creating a pull request, use `.github/PULL_REQUEST_TEMPLATE.md` as the body.
-
-- Do not omit, reorder, or rewrite template sections.
-- Check the appropriate "Type of change" box based on the actual change.
-- Do not check checklist items on behalf of the user.
-- If the PR includes UI changes, remind the user to add screenshots or a short video.
-- Explain what the change does for users, not only implementation details.
-- Use Markdown.
-
-## Pre-Submission Checklist
-
-- `yarn lint` passes when practical for the scope.
-- `yarn test` or focused relevant tests are green when practical for the scope.
-- Tests are added or updated for new data processing and utilities where applicable.
-- User-facing text is localized and follows `ha-frontend-user-facing-text` guidance.
-- Components handle loading, error, unavailable, and missing-entity states.
-- Entity existence is checked before property access.
-- Event listeners and subscriptions are cleaned up.
-- UI is accessible to screen readers and keyboard users.
-
-## Recurring Review Issues
-
-User experience and accessibility:
-
-- Forms need proper labels, helper text, and validation feedback.
-- Form markup should not cause password managers to identify fields incorrectly.
-- Clickable areas should be large enough for touch interaction.
-- Hover, active, disabled, loading, and focus states should be clear.
-
-Dialog and modal patterns:
-
-- Multi-step operations should show progress.
-- Dialog state should survive background operations correctly.
-- Cancel and close buttons should behave consistently.
-- Defaults should be helpful without blocking user override.
-
-Component design patterns:
-
-- Terminology should be consistent. Use words like "Join" or "Apply" instead of "Group" when that better matches the user action.
-- Visual hierarchy should use appropriate font sizes, weights, and spacing ratios.
-- Components should align to the design grid.
-- Badges and indicators should be placed consistently.
-
-Code quality:
-
-- Null and undefined paths should be handled explicitly.
-- Potentially undefined array and object access should be guarded.
-- Event handlers, timers, observers, and subscriptions should be cleaned up.
-
-Configuration and props:
-
-- Make configuration fields optional when sensible.
-- Provide reasonable defaults.
-- Keep APIs extensible without adding speculative abstractions.
-- Validate configuration before applying changes.
-
-## Review Flow
-
-- Identify behavioral regressions, bugs, accessibility issues, and missing tests first.
-- Keep style-only comments secondary unless they affect maintainability or user experience.
-- Prefer small, direct fixes over large refactors during review follow-up.
-- Cross-load `ha-frontend-contexts`, `ha-frontend-components`, `ha-frontend-styling`, `ha-frontend-testing`, or `ha-frontend-user-facing-text` when a finding falls in that area.

----
-
-# HA Frontend Styling
-
-Use this skill when editing CSS, layout, visual hierarchy, theme integration, responsive behavior, RTL support, or view transitions.
-
-## Theme And Layout Basics
-
-- Use Home Assistant CSS custom properties instead of hardcoded colors.
-- Use `--ha-space-*` spacing tokens instead of hardcoded spacing where possible.
-- Keep components mobile-first and enhance for desktop.
-- Keep layouts RTL-safe. Prefer logical properties when they fit.
-- Prefer `ha-*` components and current Web Awesome wrappers.
-- Avoid adding new legacy Material Web Components (`mwc-*`).
-- Scope styles to the component. Do not rely on global styles for component internals.
-
-Spacing tokens are defined in `src/resources/theme/core.globals.ts`. The scale runs from `--ha-space-1` at 4px through `--ha-space-20` at 80px in 4px increments. Common values are `--ha-space-2` at 8px, `--ha-space-4` at 16px, and `--ha-space-8` at 32px.
-
-```ts
-static get styles() {
-  return css`
-    :host {
-      padding: var(--ha-space-4);
-      color: var(--primary-text-color);
-      background-color: var(--card-background-color);
-    }
-
-    .content {
-      gap: var(--ha-space-2);
-    }
-
-    @media (max-width: 600px) {
-      :host {
-        padding: var(--ha-space-2);
-      }
-    }
-  `;
-}
-```
-
-## Interaction States
-
-- Make touch targets large enough for mobile.
-- Provide clear hover, active, focus, disabled, loading, error, and unavailable states.
-- Preserve keyboard navigation and visible focus indicators.
-- Maintain WCAG AA contrast for text and essential UI affordances.
-
-## View Transitions
-
-Use the View Transitions API only for meaningful continuity between DOM states.
-
-Core resources:
-
-- Utility wrapper: `src/common/util/view-transition.ts`, `withViewTransition()`.
-- Launch-screen fade example: `src/util/launch-screen.ts`.
-- Animation keyframes: `src/resources/theme/animations.globals.ts`.
-- Animation duration tokens: `src/resources/theme/core.globals.ts`.
-
-Implementation rules:
-
-- Use `withViewTransition()` for fallback behavior.
-- Keep transitions simple. Subtle fades and crossfades usually work best.
-- Use `--ha-animation-duration-fast`, `--ha-animation-duration-normal`, or `--ha-animation-duration-slow` for timing.
-- Ensure each `view-transition-name` is unique at any given time.
-- Remember only one view transition can run at a time.
-- View transitions operate at document level and do not work inside Shadow DOM style isolation. For web components, set `view-transition-name` on `:host` or use document-level transitions.
-- The root gets `view-transition-name: root` by default. Target `::view-transition-group(root)` to customize the default page transition.
-
-## Review Checklist
-
-- Styling uses theme variables and spacing tokens where practical.
-- Layout is mobile-first and RTL-safe.
-- Component styles are scoped.
-- Interactive states are clear and accessible.
-- Motion is subtle, tokenized, and respects reduced-motion behavior through existing globals.

-description: Home Assistant frontend validation workflow. Use when running lint, TypeScript checks, Vitest, Playwright e2e suites, dev servers, or chart-data benchmarks.
----
-
-# HA Frontend Testing
-
-Use this skill when choosing or running validation for frontend changes.
-
-## Core Commands
-
-```bash
-yarn lint          # ESLint + Prettier + TypeScript + Lit
-yarn format        # Auto-fix ESLint + Prettier
-yarn lint:types    # TypeScript compiler, run without file arguments
-yarn test          # Vitest
-yarn dev           # App dev server
-yarn dev:serve     # Local serving dev server
-```
-
-Never run `tsc` or `yarn lint:types` with file arguments. File arguments make `tsc` ignore `tsconfig.json` and can emit `.js` files into `src/`.
-
-For focused type feedback on one file, use editor diagnostics instead of a file-scoped `tsc` command.
-
-## Unit And Utility Tests
-
-- Add or update Vitest tests for data processing, utility code, and behavior that can be tested without a browser.
-- Mock WebSocket connections and API calls at boundaries.
-- Cover loading, error, unavailable, and missing-entity states where relevant.
-- Test accessibility-sensitive behavior when it can be asserted without brittle DOM internals.
-
-## Dev Servers
-
-`yarn dev` builds and watches the app, served by a running Home Assistant core configured through `development_repo`.
-
-`yarn dev:serve` also serves locally and supports `-c` for the core URL and `-p` for the port. Default local serving port is 8124.
-
-Dev server commands support `--background`, `--status`, `--stop`, and `--logs [--follow]`.
-
-## Playwright E2E
-
-Each suite has its own dev server port. Playwright reuses an existing server locally when the port is already running; otherwise it performs a slow full build. The rspack watcher recompiles on save, so reruns should not need a restart.
-
-Start the relevant suite server, then run that suite:
-
-| Suite   | Server                          | Test command            |
-| ------- | ------------------------------- | ----------------------- |
-| App     | `yarn test:e2e:app:dev` on 8095 | `yarn test:e2e:app`     |
-| Demo    | `yarn dev:demo` on 8090         | `yarn test:e2e:demo`    |
-| Gallery | `yarn dev:gallery` on 8100      | `yarn test:e2e:gallery` |
-
-Server reuse and `--stop` use the `/__ha_dev_status` health check, so starting or stopping twice is harmless.
-
-Use `-g "<title>" --project=chromium` to narrow a run. `yarn test:e2e` runs all three suites. Run suites directly; piping through output truncation hides progress and failures.
-
-The app suite uses a stripped-down harness for e2e. Demo and gallery use their normal dev servers.
-
-## Benchmarks
-
-For chart data transforms such as history, statistics, energy, and downsampling, follow `test/benchmarks/README.md`.
-
-Use seeded fixtures, characterization snapshot tests, and `yarn test:bench` before and after optimization. Optimizations must keep output bit-identical.
-
-## Verification Selection
-
-- Documentation-only change: no code test required unless examples or commands changed.
-- Type-only or utility change: run focused Vitest if available, then `yarn lint:types` if practical.
-- Lit component change: run relevant tests plus lint or typecheck depending on scope.
-- E2E-sensitive flow: start the relevant e2e dev server and run the narrow Playwright suite.
-- Broad refactor: run `yarn lint` and relevant test suites when practical.

----
-
-# HA Frontend User-Facing Text
-
-Use this skill for all user-facing text, translations, labels, buttons, dialog copy, errors, helper text, and review comments about wording.
-
-## Localization
-
-- All user-facing text must be translatable.
-- Add translation keys to `src/translations/en.json` when introducing new strings.
-- Use the localization system instead of inline user-visible strings.
-- Prefer complete localized strings with placeholders over concatenating translated fragments.
-- Give translators enough context through key naming and placeholders.
-
-```ts
-this.hass.localize("ui.panel.config.updates.update_available", {
-  count: 5,
-});
-```
-
-## Voice And Style
-
-- Use American English.
-- Use a friendly, informational tone.
-- Address users directly with "you" and "your" when appropriate.
-- Be inclusive, objective, and non-discriminatory.
-- Be concise and clear.
-- Use active voice.
-- Avoid jargon where a familiar home automation term works.
-- Always write "Home Assistant" in full. Do not use "HA" or "HASS" in user-facing copy.
-- Spell out terms when possible.
-- Use sentence case for titles, headings, buttons, labels, and UI elements.
-- Use the Oxford comma in lists.
-- Prefer "like" over "e.g." and "for example" over "i.e.".
-- Avoid all caps for emphasis. Use wording, bold, or italics instead.
-- Write for both technical and non-technical users.
-
-Sentence case examples:
-
-- Use: "Create new automation"
-- Avoid: "Create New Automation"
-- Use: "Device settings"
-- Avoid: "Device Settings"
-
-## Terminology
-
-Use "integration" instead of "component" for user-facing product language unless referring to a frontend component in developer context.
-
-Technical product terms are lowercase in prose: automation, entity, device, service.
-
-## Delete, Remove, Create, Add
-
-Use "Remove" for actions that can be restored or reapplied:
-
-- Removing a user's permission.
-- Removing a user from a group.
-- Removing links between items.
-- Removing a widget from a dashboard.
-- Removing an item from a cart.
-
-Use "Delete" for permanent, non-recoverable actions:
-
-- Deleting a field.
-- Deleting a value in a field.
-- Deleting a task.
-- Deleting a group.
-- Deleting a permission.
-- Deleting a calendar event.
-
-Use "Add" for already-existing items:
-
-- Adding a permission to a user.
-- Adding a user to a group.
-- Adding links between items.
-- Adding a widget to a dashboard.
-- Adding an item to a cart.
-
-Use "Create" for something made from scratch:
-
-- Creating a new field.
-- Creating a new task.
-- Creating a new group.
-- Creating a new permission.
-- Creating a new calendar event.
-
-Create pairs with Delete. Add pairs with Remove.
-
-## Review Checklist
-
-- Text is localized.
-- Copy uses sentence case.
-- "Home Assistant" is written in full.
-- Delete/Remove and Create/Add match recoverability and object lifecycle.
-- Placeholders are used instead of string concatenation.
-- The wording is concise and understandable without implementation knowledge.

-# Home Assistant Frontend Agent Guide
-
-You are helping develop the Home Assistant frontend. This repository is a TypeScript application built from Lit-based Web Components for the Home Assistant web UI.
-
-For gallery-specific documentation, demos, page structure, and examples, read `gallery/AGENTS.md` when working under `gallery/`.
-
-## Essential Commands
-
-```bash
-yarn lint          # ESLint + Prettier + TypeScript + Lit
-yarn format        # Auto-fix ESLint + Prettier
-yarn lint:types    # TypeScript compiler, run without file arguments
-yarn test          # Vitest
-yarn dev           # App dev server, supports --background/--status/--stop/--logs
-yarn dev:serve     # Local serving dev server, supports -c core URL, -p port, and dev flags
-```
-
-Never run `tsc` or `yarn lint:types` with file arguments. When `tsc` receives file arguments, it ignores `tsconfig.json` and can emit `.js` files into `src/`. Always run `yarn lint:types` without arguments. For individual file type checking, rely on editor diagnostics.
-
-## Architecture
-
-- The frontend uses custom elements built with Lit and TypeScript strict mode.
-- Components communicate with the backend through the Home Assistant WebSocket API.
-- Use `ha-` for Home Assistant components, `hui-` for Lovelace UI components, and `dialog-` for dialogs.
-- Prefer `ha-*` components and current Web Awesome wrappers. Avoid adding new legacy `mwc-*` usage.
-- Leaf components should consume narrow Lit contexts instead of taking the broad `hass` object unless they are containers that own and provide `hass`.
-
-## Development Standards
-
-- Use strict TypeScript, proper interfaces, and `import type` for type-only imports.
-- Avoid `any`; model data with existing Home Assistant types or narrow new types.
-- Keep imports organized and remove unused imports.
-- Do not use `console`; use existing logging or user-visible error patterns.
-- Use `@state()` for internal Lit state and `@property()` for public API.
-- Do not query or manipulate DOM manually when Lit decorators, component refs, or render state are appropriate.
-- Scope styles to components, use theme custom properties, and keep layouts mobile-first and RTL-safe.
-- All user-facing text must be localized through the translation system.
-
-## Project Skills
-
-Detailed guidance lives in project skills under `.agents/skills/`. Load the matching skill before detailed implementation or review:
-
-- `ha-frontend-contexts`: Lit contexts, `hass` migration, and rerender-sensitive state access.
-- `ha-frontend-components`: dialogs, forms, alerts, shortcuts, tooltips, panels, and Lovelace cards.
-- `ha-frontend-styling`: theme variables, spacing tokens, responsive layout, RTL, and view transitions.
-- `ha-frontend-testing`: lint, typecheck, Vitest, Playwright e2e dev servers, and benchmarks.
-- `ha-frontend-user-facing-text`: localization, terminology, sentence case, and Home Assistant text style.
-- `ha-frontend-review`: PR template use, review checklist, and recurring review issues.
-
-## Pull Requests
-
-When creating a pull request, use `.github/PULL_REQUEST_TEMPLATE.md` as the PR body. Preserve template sections, check only the appropriate type-of-change boxes, and do not check checklist items on behalf of the user. If the PR includes UI changes, remind the user to add screenshots or a short video.
