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.
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.
