API

interface ExperimentalChromeToolsTransportOptions  {
createSession?: (options: ChromeToolsSessionOptions) => Promise<ChromeToolsSession>;
events?: {
        downloadRequired?: (status: 'downloadable' | 'downloading') => void | Promise<void>;
        downloadProgress?: (percent: number) => void;
        sessionState?: (state: 'created' | 'destroyed') => void;
    };
outputLanguage?: SupportedOutputLanguage;
schemaFinalization?: 'after-tool-planning';
timeoutMs?: number;
toolPhase?: (context: ChromeToolsTurnContext) => ChromeToolPhase;
}
createSession

Optional session provider; native capability checks still apply.

events
{
        downloadRequired?: (status: 'downloadable' | 'downloading') => void | Promise<void>;
        downloadProgress?: (percent: number) => void;
        sessionState?: (state: 'created' | 'destroyed') => void;
    }
outputLanguage

Text language negotiated for both input and output. Defaults to English.

schemaFinalization
'after-tool-planning'

Finalize structured or component UI answers after unconstrained tool planning. Adds one terminal inference pass; individual schemas remain model-dependent.

timeoutMs
number

Bounds an entire session, including creation and inference; 1–1200000ms.

toolPhase

Select one tool or direct schema finalization from immutable current-turn history. Requires schemaFinalization and a response schema.
