# Agent Studio Embeddable grok-class coding agent via `BridgeSwarm.agent.create()`. Enable QVAC in Control Center → Settings first. Built-in tools (`read_file`, `write_file`, `search_replace`, `grep`, `list_dir`, `run_terminal_cmd`) stay under BridgeSwarm storage unless extra workspace roots are granted in Settings. Register page-owned tools (handlers never leave the tab): ```js const session = await BridgeSwarm.agent.create({ model: 'qwen3.5-4b' }) await session.addTool({ name: 'page_time', description: 'Current time in the web page', parameters: { type: 'object', properties: {} }, execute: () => ({ now: new Date().toISOString() }), }) await session.prompt('Create hello.js then call page_time') ``` This demo registers `page_time` on every new session.
