## What it does

The skill guides agents on interacting with the Unbrowse platform via CLI commands or remote MCP tools. The host agent discovers existing site routes, grabs page contents in Markdown, and operates a cloud browser for tasks that need rendering. Route execution and saved sessions remain on the remote service.

Authentication relies on OAuth in a local browser: the user receives a sign-in link via email and approves access without copying tokens into prompts. For headless systems or continuous integration pipelines, credentials pass through the `UNBROWSE_API_KEY` environment variable instead. Tools like `scrape` and `index` require CLI version 12.2.0 or newer.

Site requests originate from your local IP by default, so you must explicitly pass `--from-unbrowse` to route traffic through external infrastructure. When installed as an environment plugin, it intentionally blocks native browser actions unless overridden by an explicit environment flag.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add unbrowse-ai/unbrowse --skill unbrowse -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/unbrowse/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/unbrowse/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add unbrowse-ai/unbrowse --skill unbrowse -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/unbrowse/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add unbrowse-ai/unbrowse --skill unbrowse -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/unbrowse/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install unbrowse-ai/unbrowse unbrowse
```

2. **Manually: put the files in place**
- File: `.github/skills/unbrowse/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add unbrowse-ai/unbrowse --skill unbrowse -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/unbrowse-ai/unbrowse --path plugins/claude-code/skills/unbrowse
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/unbrowse/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add unbrowse-ai/unbrowse --skill unbrowse -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/unbrowse-ai/unbrowse/tree/HEAD/plugins/claude-code/skills/unbrowse/SKILL.md

## When to use it
- extract clean web page content into Markdown
- discover and trigger pre-indexed routes for target websites
- run authenticated cloud browser actions without storing passwords in chat
- train new site routes using cloud indexing tools

## Example prompts
- Check current authentication status with npx unbrowse whoami
- Fetch page content as Markdown using unbrowse scrape <url>
- Discover available site automation tools with unbrowse discover <query>

# Unbrowse

Use the hosted service at `https://unbrowse.ai`. Execution, indexed routes and website sessions stay server-side. This skill supplies operating guidance; signing in is OAuth, below.

## Onboarding: sign in with OAuth

Sign-in is OAuth in the person's browser: an emailed sign-in link, then **Allow**. No password, and nothing to paste. Never ask the person for a token or key in chat.

Check first, then sign in only what is missing:

1. MCP: if `unbrowse_discover` is in this session's tool list, the MCP is signed in.
2. CLI: `npx unbrowse whoami`. Exit 0 means signed in. Exit 3 means not signed in.

Sign in the MCP (agent hosts):

```sh
claude mcp add --transport http unbrowse https://unbrowse.ai/mcp
```

```json
{"mcpServers":{"unbrowse":{"url":"https://unbrowse.ai/mcp"}}}
```

The host runs the OAuth sign-in itself (in Claude Code: `/mcp`, pick `unbrowse`, Authenticate). Do not put a bearer header in the config; with one set, hosts skip OAuth. A URL in a config is not a signed-in session: until the host finishes OAuth, the Unbrowse tools are not listed.

Sign in the CLI:

```sh
npx skills add unbrowse-ai/unbrowse && npx unbrowse login
```

`unbrowse login` opens the sign-in page in the browser on this machine. The person enters their email, opens the link, presses **Allow**; the CLI prints `Signed in to https://unbrowse.ai (workspace ws_…)` and stores the token at `~/.config/unbrowse/cli.json` (mode 0600, refreshed automatically).

From an agent's shell (no terminal for the person): run `npx unbrowse login --no-open` in the background, give the person the `https://unbrowse.ai/authorize?…` link it prints, and wait for the `Signed in` line. The link returns to `127.0.0.1` on this machine, so the person must open it in a browser on the same machine. On a remote or headless box, run `npx unbrowse login --device` and approve the code it shows from any device, or use an API key (below). Any other command run with no sign-in starts the same browser sign-in when it has a terminal; without one it exits 3 and asks for `unbrowse login`.

Then the first call: `npx unbrowse run 'top stories on hacker news'`. The site requests go from the person's own IP by default; `--from-unbrowse` sends them from Unbrowse instead.
