What it does

Ha Frontend Events is an agent skill from home-assistant/frontend. Home Assistant frontend event patterns. Use when typing event handlers, using HASSDomEvent types, dispatching with fireEvent, or declaring HASSDomEvents and event maps.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design. It works with Home Assistant. The repository describes itself as: :lollipop: Frontend for Home Assistant. The licence is Apache-2.0.

When your agent uses it

Typing event handlers
Using HASSDomEvent types
Dispatching with fireEvent
Declaring HASSDomEvents and event maps

Example prompts

“/ha-frontend-events”

What it can do on your machine

Read from SKILL.md and the folder at commit 3280113. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ha Frontend Events loads about 1.1k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 330 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~47
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

HA Frontend Events

Use this skill when implementing or reviewing event listeners and custom event contracts. Cross-load ha-frontend-components when the work also involves dialogs, forms, alerts, shortcuts, tooltips, panels, Lovelace cards, or buttons.

Event Handling

Use the event types from src/common/dom/fire_event.ts instead of plain Event, generic CustomEvent, or element casts when they express the handler contract:

Use HASSDomCurrentTargetEvent<T> to read the element on which the listener was registered through ev.currentTarget.
Use HASSDomTargetEvent<T> only to read the element that originated the event through ev.target.
Use HASSDomEvent<T> to read a custom event payload through ev.detail.
Use ValueChangedEvent<T> from src/types.ts for the standard value-changed event.
Prefer an event type exported by the component being listened to, such as HaSelectSelectEvent<T, Clearable> or HaDropdownSelectEvent<TValue, TData>, over reconstructing its detail type.
Use ActionHandlerEvent from src/data/lovelace/action_handler.ts for Lovelace tap, hold, and double-tap handlers.

Import event and element types with import type:

import type {
  HASSDomCurrentTargetEvent,
  HASSDomEvent,
  HASSDomTargetEvent,
} from "../common/dom/fire_event";
import type { HaCheckbox } from "../components/ha-checkbox";
import type { HaEntityPicker } from "../components/entity/ha-entity-picker";
import type { HaRadioGroup } from "../components/radio/ha-radio-group";
import type { ValueChangedEvent } from "../types";

Type the handler so the selected property can be read directly. Do not cast ev.currentTarget or assign it to a single-use variable:

private _scopeChanged(ev: HASSDomCurrentTargetEvent<HaRadioGroup>): void {
  this._scope = ev.currentTarget.value;
}

private _checkedChanged(ev: HASSDomTargetEvent<HaCheckbox>): void {
  this._checked = ev.target.checked;
}

private _valueChanged(ev: ValueChangedEvent<string>): void {
  this._value = ev.detail.value;
}

private _itemSelected(ev: HASSDomEvent<{ id: string }>): void {
  this._selectedId = ev.detail.id;
}

Use intersections when a handler needs more than one facet of an event. Keep the native event type when the handler reads native fields such as key, modifier keys, dataTransfer, or focus relationships:

private _entityChanged(
  ev: ValueChangedEvent<string> & HASSDomCurrentTargetEvent<HaEntityPicker>
): void {
  ev.currentTarget.value = ev.detail.value;
}

private _keyDown(
  ev: KeyboardEvent & HASSDomCurrentTargetEvent<HTMLInputElement>
): void {
  if (ev.key === "Enter") {
    this._submit(ev.currentTarget.value);
  }
}

Dispatch Home Assistant component events with fireEvent() instead of constructing Event or CustomEvent directly. Register the event name and detail type by augmenting HASSDomEvents; use undefined when an event has no detail. fireEvent() constrains event names and supplied detail, and events bubble and cross shadow boundaries by default:

fireEvent(this, "item-selected", { id: item.id });
fireEvent(this, "refresh-requested");

When an event is already registered, derive handler and listener types from its registration rather than repeating the payload shape:

private _itemSelected(
  ev: HASSDomEvent<HASSDomEvents["item-selected"]>
): void {
  this._selectedId = ev.detail.id;
}

HASSDomEvents types fireEvent() calls. Augment HTMLElementEventMap for typed listeners on HTML elements, or GlobalEventHandlersEventMap when the event is handled on global event targets.

In component files, prefer placing global event declarations after the class at the bottom of the file. Preserve the existing placement when editing established files; foundational type, helper, and mixin files commonly keep declarations near the top before their consumers.

declare global {
  interface HASSDomEvents {
    "item-selected": { id: string };
    "refresh-requested": undefined;
  }

  interface HTMLElementEventMap {
    "item-selected": HASSDomEvent<HASSDomEvents["item-selected"]>;
  }
}
