----
-
-# 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.

-| `uiContext`                                                          | themes, selected theme, panels, sidebar, and UI state                                  |

-
-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.

----
-
-# HA Frontend Testing
-
-Use this skill when choosing or running validation for frontend changes.
-
-## Test Helpers
-
-- Before adding or changing tests, inspect the relevant suite's existing helpers and fixtures. Reuse them instead of duplicating setup, test data, navigation, interactions, waits, or assertions.
-- When the same test flow appears more than once, move it into the closest suite-local helper with a focused interface.
-- Keep one-off test behaviour in the test unless a helper makes the intent materially clearer. Do not hide the behaviour under test behind broad, configurable abstractions.
-
-## 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]`. Prefer managed background mode while iterating so the watcher stays available across test runs without occupying the terminal.
-
-## Playwright E2E
-
-Each suite has its own dev server port. Prefer running the relevant server in the background while iterating. Playwright reuses it 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   | Background server                            | Test command            |
-| ------- | -------------------------------------------- | ----------------------- |
-| App     | `yarn test:e2e:app:dev --background` on 8095 | `yarn test:e2e:app`     |
-| Demo    | `yarn dev:demo --background` on 8090         | `yarn test:e2e:demo`    |
-| Gallery | `yarn dev:gallery --background` on 8100      | `yarn test:e2e:gallery` |
-
-Use the same server command with `--status`, `--logs [--follow]`, or `--stop` to manage it. Server reuse and `--stop` use the `/__ha_dev_status` health check, so starting or stopping twice is harmless.
-
-Local runs against a watched development server do not always match CI's clean build artifacts, environment, sharding, or worker configuration. Use background servers for the fast iteration loop, but confirm the relevant CI jobs complete successfully before considering E2E changes verified.
-
-Use `-g "<title>" --project=chromium` to narrow a run. `yarn test:e2e` runs all three suites in parallel when every managed server is available, otherwise it runs them sequentially to prevent cold builds racing over shared generated assets. 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.
