Action

An executable interaction exposed by an object or surface. Actions connect user intent to service behavior.

Examples:

• open
• join
• navigate
• message
• save
• launch
• share
• pin

Sub-concepts:

• action target — the destination or system affected by the action (surface, service, object, route, external runtime)
• action provider — the service executing the action

Allowed:

• action
• [verb] action (e.g., join action, save action)
• action target
• action provider

Forbidden:

• command (implies CLI or OS context)
• operation (too technical)
• function (engineering term)
• button (UI implementation detail; not a model noun)
• event (avoid — event has a canonical social meaning; see: event)

Notes:

• Actions belong to objects and surfaces, not to blocks or cards. A card may expose an object's actions, but the action is the object's.
• Do not use "event" to mean a user interaction or UI action. "Event" means a social event (see: event).
