# browser-relay

This skill points the agent at the Chrome you already have open, logins included: it reads pages, clicks controls and takes screenshots. Useful when a task sits behind a sign-in.

## What it does

browser-relay reuses your running browser and its session state. A tab is picked by URL and title, and a foreground switch should not pull your work elsewhere. Give every independent task its own session name: `browser-relay tabs`, then `browser-relay read --tab <id> --session <task-name>`.

Pick the observation that matches the question. `read` keeps the main content with semantic groups, full text and whole URLs, while `read --ref <ref>` narrows to an observed subtree. `observe` covers the entire page with controls and states, and screenshots are for canvas, layout or missing accessible text. When output is clipped, follow `nextCursor`; it stops working after navigation.

Batch actions once targets and order are known: fill a field, pick an option, submit, wait for the expected result. Stop the batch before an unfamiliar page or dialog. Refs go stale on navigation or removal, and guessing refs or tab IDs is off the table. Background clicks use DOM activation and come back as `strategy:'dom'`, so they are not a trusted mouse gesture. An idle lease expires after two minutes, which is why standalone CLI calls renew it on every operation and `session heartbeat --session <name>` keeps it alive in between. A stopped session cannot restart on its own: resumed work needs a fresh ID.

## Requirements
- Works with: Chrome

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add reliefeai/browser-relay --skill browser-relay -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add reliefeai/browser-relay --skill browser-relay -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add reliefeai/browser-relay --skill browser-relay -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install reliefeai/browser-relay browser-relay
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add reliefeai/browser-relay --skill browser-relay -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/reliefeai/browser-relay --path skills/browser-relay
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add reliefeai/browser-relay --skill browser-relay -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/reliefeai/browser-relay/tree/HEAD/skills/browser-relay/SKILL.md

## When to use it
- read an account page that blocks logged-out visitors
- fill a form and wait for the result to appear
- capture a canvas screenshot where no accessible text exists
- parse a feed without counting recommendations as comments
- run a slow job asynchronously and keep its task ID

## Example prompts
- List the open tabs and read the orders page in session `orders`
- Fill the search box, click "Search records" and wait for the "Results" heading
- Take a screenshot in `both` mode and save it to `/tmp/page.png`

# Browser Relay

Use the user's existing browser and login state. Select an actual tab ID by URL
and title; a foreground change must not redirect your work.

```bash
browser-relay tabs
browser-relay read --tab <id> --session <task-name>
```

Use a distinct session name for each independent task. Managed operations claim
the tab for that session. Another owner must release or hand it off before you
operate it; never stop someone else's session merely to gain access. These
leases coordinate trusted clients, not access control against local software.

## Choose the observation that answers the question

- **Reading:** `read` focuses on main content and preserves semantic groups,
  complete text and full URLs. `read --ref <ref>` reads an observed subtree.
- **Operating:** `observe` includes the whole page, controls, states and refs.
  Use it to find navigation, dialogs or controls outside the main content.
- **Seeing:** use screenshots for canvas, layout, missing accessible text or a
  semantic action with an unexpected outcome. In the runtime,
  `tab.observe({mode:'both'})` returns a snapshot and screenshot together. With
  CLI use `observe --mode both --output /tmp/page.png --tab <id> --session <name>`.

Follow `nextCursor` (`read --cursor <cursor>`) when an observation is truncated.
A cursor continues the same captured text; it is not a new live observation.
After navigation it expires. If the page exceeds the cache limit, read a smaller
subtree. Do not report a partial result as the complete page or article.
Runtime output has a separate budget: if runtimeOutput.nextCursor is returned,
run its readWith expression in the same session to recover the clipped output.
Then follow any browser nextCursor it contains; a new diff cannot recover it.
A site's “Show more” is separate from output pagination: expand the site control
when the task needs the full article. Group parents, quoted material and replies
remain distinct; do not count recommendations as comments or duplicate cards.
