Agent-ready implementation packet

Headless SDK Agent Builder

Configure the integration once, then hand a coding agent the exact package names, safety rules, files, snippets, and tests it needs to avoid hallucinated APIs or browser credentials.

Selected capabilities

client tools, typed rich content, diagnostics

Preflight checks

No browser secrets

Token exchange stays behind a server route.

Typed message parts

Generated UI renders message.parts instead of widget DOM.

Tool schemas

Selected tools include JSON Schema input validation.

Mock transport test

Test snippet uses createMockChatClient and mockScenarios.

Customer proxy transport

Direct mock transport remains local-only.

Generated artifacts

Copy the tabs into a coding-agent task or use them as the integration checklist.
