## What it does

The skill hooks into the browser you already have open, keeping existing logins, cookies, and tabs intact. This allows an agent to inspect internal pages, run responsive audits, and capture network calls without manual credential exports. Work runs through the `owb` command-line tool, which talks to a local background daemon.

For safe tab handling, multi-step flows need `owb task begin` to isolate new tabs into a dedicated task group. A plain `owb task end` only archives context and does not close tabs; `owb tab close-group` handles the actual cleanup. Running concurrent missions breaks state because the daemon tracks only one active task pointer.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add woniu9524/open-web-bridge --skill owb -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add woniu9524/open-web-bridge --skill owb -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add woniu9524/open-web-bridge --skill owb -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install woniu9524/open-web-bridge owb
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add woniu9524/open-web-bridge --skill owb -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/woniu9524/open-web-bridge --path owb-skills/owb
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add woniu9524/open-web-bridge --skill owb -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/woniu9524/open-web-bridge/tree/HEAD/owb-skills/owb/SKILL.md

## When to use it
- read authenticated pages behind an active login session
- fill multi-step web forms inside the user's browser
- inspect network requests and analyze traffic signatures
- audit responsive layout and accessibility issues

## Example prompts
- Open <url> in a new tab with owb and inspect the login form
- Start an owb task, fill the profile form, and close the task tab group
- Inspect how the current page signs its network requests using owb

name: owb
description: Open Web Bridge (OWB) — drive the user's own real browser with the `owb` command. Read pages behind their existing logins, gather and cross-check information, fill forms, walk multi-step flows, debug their site, audit responsive/accessibility behavior, and capture or reverse-engineer network traffic. Use this whenever the user mentions Open Web Bridge or OWB by name, or a task involves "go look at this page", "pull these pages together", "do this for me on that site", "my site's frontend is broken", "how is this request signed", or anything at all that needs a logged-in session or a real browser environment rather than a plain HTTP fetch.

# owb (Open Web Bridge) — driving the user's real browser

`owb`, the Open Web Bridge CLI, operates **the browser the user is using right
now**: their logged-in accounts, their settings, their open tabs. That is why you
can reach content that exists only behind a login, and complete actions that
require an identity.

For the same reason, **every step lands on a real person's account** and **they may
be using this browser beside you**. Read freely; ask before changing anything;
open pages in new tabs so you don't take over what they are looking at.

## How to use this document

**In a hurry?** Read "Before you start" → "The shape of a task" → "The core loop".
This file is the trunk; **five reference files live in `references/`, read on demand:**

| File | When to read it |
| --- | --- |
| `references/commands.md` | Arguments, defaults, limits and return fields — **check before writing a complex call instead of guessing argument names** |
| `references/recipes.md` | Longer recipes for a specific job: extraction, clicking quirks, drag/canvas, downloads, site debugging, responsive audits, logins, flows |
| `references/debugging.md` | Debugging and reverse-engineering: capture, HAR processing, hooks, breakpoints, script patching, offline signature verification |
| `references/field-notes.md` | Long-tail oddities seen in the field (the "Reality check" table below is the symptom index — come here once a symptom matches) |
| `references/relay.md` | The user asks about remote-controlling their browser, or `daemon-status` reports relay mode |

**For anything not documented here**: this file cannot cover all 80 commands.
`owb help` lists all 16 groups, `owb help <group>` expands one, and
`owb call <tool> --args '<json>'` calls any underlying tool directly.
**Don't guess command names — look them up.**

## Before you start

```bash
owb          # self-check
```

- `✓ daemon` + `✓ extension connected` → go
- `✗ extension not connected` → **stop and tell the user** to click the extension
  icon in their toolbar and check its status. Hammering the tools will only
  produce `NO_EXTENSION` forever.
- Command not found → `npm i -g open-web-bridge`, then `owb setup`
- `[owb] daemon not running, starting it…` on stderr during the first command is
  **not an error** — the CLI is starting the daemon. Wait for it to connect;
  don't report it as a fault.

The self-check reports one of two modes: **local** (default; daemon and browser on
one machine) and **relay** (browser on the user's machine, agent elsewhere, paired
