BrowserSkill

Let AI agents use your browser without interrupting your work.

English · 中文

BrowserSkill connects Cursor, Claude Code, Codex, OpenClaw, CodeBuddy, WorkBuddy, Pi, Hermes Agent, and other shell-capable AI agents to your already logged-in browser.

Need the agent to touch a tab you already have open? It must borrow that tab explicitly, return it when the task is done, and leave the rest of your browser alone.

BrowserSkill Advantages

• Reuse real login state: Agents can work with sites you are already signed into, without separate test accounts.
• Keep working uninterrupted: browser tasks run in a separate, visible Agent Window, so you can keep using your own browser.
• Support any Agent: any Agent that can call a shell can use BrowserSkill through the bsk CLI, with no lock-in to a specific model, Agent framework, or harness.
• Built-in human-in-loop: when a task hits captcha, login, confirmation dialogs, or other human-only steps, the Agent can ask you to take over and then continue afterwards.

Runtime Environment

BrowserSkill has two local runtime pieces: the bsk CLI/daemon and the browser extension.

Quick Start

Start a new Agent session and write a prompt that needs the browser, for example:

/browser-skill open example.com and summarize what is on the page.

How It Works

BrowserSkill is a local bridge between your agent harness and your browser.

The agent never talks to the browser directly. It asks the bsk CLI to perform a browser task; the local daemon routes that request to the extension; the extension runs it in an Agent Window.

For Developers

The repository is a Cargo + pnpm workspace:

• crates/bsk-cli — bsk CLI and local daemon
• crates/bsk-protocol — shared wire types and JSON schemas
• apps/extension — browser extension
• packages/ui and packages/i18n — shared extension UI support
