Composer

The standard chat input — a PromptInput pre-assembled with attachments, tools and submit.

Standing permission-policy chooser — how far the agent may act on its own, not whether one call proceeds.

Chat composer FORM (Enter submits) emitting a message to the app's runtime.

Composer control for an ordered reasoning-budget scale whose indicator fills as the level rises.

Composer control for the agent's operating mode — an app-defined enum of how autonomously it may act.

The slash-command palette over a composer — type /, filter by prefix, pick a command with the keyboard.

The chat composer with @-mentions: typing @ opens a people and resource picker, and the chosen mentions travel with the message.
