**BrowserSkill** connects Cursor, Claude Code, Codex, OpenClaw, CodeBuddy,
WorkBuddy, Pi, Hermes Agent, DeepSeek Harness, and other 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.

| Runtime | Support |
| --- | --- |
| Operating systems | macOS (Apple Silicon and Intel), Linux (x64 and ARM64), Windows x64 |
| Browsers | Chrome and Microsoft Edge are supported; other Chromium-based browsers are expected to work when they support unpacked Chromium extensions; Firefox is planned |

## Quick Start

### 1. Install the CLI and skill

<details open>
<summary><b>Install with your Agent (recommended)</b></summary>

<br>

Already using Cursor, Claude Code, Codex, WorkBuddy, or another shell-capable
agent? Just copy this one line and send it to your agent — it will install the
CLI and skill for you. You will install the browser extension yourself in step 2
below.

```text
Set up browser-skill on this machine by following https://raw.githubusercontent.com/Tencent/BrowserSkill/main/AGENT_INSTALL.md
```

</details>

<details>
<summary><b>Manual install</b></summary>

<br>

Install the CLI and skill with the commands below.

#### Install the `bsk` CLI

**macOS / Linux** (recommended — installs to `~/.local/bin`):

```bash
curl -fsSL https://raw.githubusercontent.com/Tencent/BrowserSkill/main/install.sh | sh
```

**Windows** (PowerShell — installs to `~/.local/bin`):

```powershell
irm https://raw.githubusercontent.com/Tencent/BrowserSkill/main/install.ps1 | iex
```

Verify the binary:

```bash
bsk --version
```

#### Install the skill

BrowserSkill ships a skill that teaches your agent harness how to use `bsk`. For
these harnesses, install it in one step:

  </tr>
</table>
</p>

```bash
bsk install-skill
```

Use <kbd>Space</kbd> to select the Agent harness you want to install into, then
press <kbd>Enter</kbd> to install the skill. Run `bsk install-skill --list` to see
internal variants and install paths.

Other shell-capable agent harnesses are supported too. Copy
[`skill/SKILL.md`](skill/SKILL.md) into your harness's skills directory as
`browser-skill/SKILL.md` to install the skill manually. DeepSeek Harness uses a
dedicated plugin instead — see [DeepSeek Harness plugin](#deepseek-harness-plugin).

</details>

### 2. Install the browser extension

Due to current browser security policies, you still need to manually install
the extension for your browser.
Open the store link for your browser and confirm the extension installation:

| Browser | Store listing |
| --- | --- |
| Chrome | [Chrome Web Store](https://chromewebstore.google.com/detail/browserskill/hhcmgoofomhgciiibhipgmgkgnoenaoi) |
| Microsoft Edge | [Edge Add-ons](https://microsoftedge.microsoft.com/addons/detail/browserskill/emacgiaaaiojkkpkddmmdfhmokgmnikg) |

On other Chromium-based browsers, install the Chrome Web Store build.

### 3. Start using BrowserSkill

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

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

## DeepSeek Harness plugin

Using [DeepSeek Harness](https://github.com/deepseek-ai/deepseek-harness) (`dsh`)?
BrowserSkill ships a first-class dsh plugin on npm as
[`@wxg-prc-cpg/browser-skill-dsh-plugin`](https://www.npmjs.com/package/@wxg-prc-cpg/browser-skill-dsh-plugin).
It gives the agent native `browser_*` tools and a live view of its browser sessions
in the Web UI. The plugin runs `bsk` on the agent's behalf.

Install the `bsk` CLI and connect the browser extension first. Then add the plugin
to a dsh profile and start it (replace `web` with your profile name):

```sh
dsh plugin --profile web add @wxg-prc-cpg/browser-skill-dsh-plugin
dsh --profile web
```

The plugin includes the `browser-skill` skill, so `bsk install-skill` is not needed
for dsh. Installed plugins do not update automatically. To upgrade this plugin:

```sh
dsh plugin --profile web update @wxg-prc-cpg/browser-skill-dsh-plugin --latest
```

Restart the profile after upgrading. See the
[plugin README](packages/dsh-plugin-browserskill/README.md) for usage and configuration.

## How It Works

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

  subgraph Harness["Agent Harness"]
    Agent["Cursor / Claude Code / Codex / OpenClaw"]
  end

  subgraph Local["Your Machine"]
    CLI["bsk CLI"]

    Extension["BrowserSkill extension"]
  end

  subgraph Browser["Browser Profile"]

    UserWindows["Your normal browser windows"]
  end

  CLI -->|"local IPC"| Daemon

  Extension -->|"automates"| AgentWindow
  Extension -.->|"borrow tab only when asked"| UserWindows

  style UserWindows fill:#f8fafc,stroke:#cbd5e1,color:#334155
```

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. DeepSeek Harness takes the same path
through the [plugin](#deepseek-harness-plugin): the agent calls injected
`browser_*` tools, and the plugin invokes `bsk` on its behalf.

## 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
- `packages/dsh-plugin-browserskill` — DeepSeek Harness plugin (`@wxg-prc-cpg/browser-skill-dsh-plugin`)
- [`evals/browser`](evals/browser/README.md) — deterministic local pages and agent-neutral browser capability evaluation
