Safe Browser

Build a local browser-agent demo where the generated runtime agent has exactly one browser capability: safe_browser. The tool owns the Playwright/CDP session, enables Fetch interception for all requests, and fails any request whose host is not allowlisted.

This skill is a builder guide. The skill itself is not the runtime boundary; the generated Claude Agent SDK app is.

When to Use

The user asks for a browser agent that must stay on an allowlisted site.

The user wants to demonstrate prompt-injection or link-following containment.

The user asks to build a scraper or browser workflow with domain policy.

The user asks for a Claude Agent SDK example first. Keep OpenAI Agents SDK variants out unless requested.

Default Approach

Use the Claude Agent SDK local template:

don't have the plugin yet? install it then click "run inline in claude" again.
