# Web Browser Skill

Minimal CDP tools for collaborative site exploration.

## Start Chrome

```bash
./scripts/start.js              # Fresh profile
./scripts/start.js --profile    # Copy your profile (cookies, logins)
```

Start Chrome on `:9222` with remote debugging.

## Navigate

```bash
./scripts/nav.js https://example.com
./scripts/nav.js https://example.com --new
```

Navigate current tab or open new tab.

## Evaluate JavaScript

```bash
./scripts/eval.js 'document.title'
./scripts/eval.js 'document.querySelectorAll("a").length'
./scripts/eval.js 'JSON.stringify(Array.from(document.querySelectorAll("a")).map(a => ({ text: a.textContent.trim(), href: a.href })).filter(link => !link.href.startsWith("https://")))'
```

Execute JavaScript in active tab (async context).  Be careful with string escaping, best to use single quotes.

## Screenshot

```bash
./scripts/screenshot.js
```

Screenshot current viewport, returns temp file path

## Pick Elements

```bash
./scripts/pick.js "Click the submit button"
```

Interactive element picker. Click to select, Cmd/Ctrl+Click for multi-select, Enter to finish.

## Dismiss Cookie Dialogs

```bash
./scripts/dismiss-cookies.js          # Accept cookies
./scripts/dismiss-cookies.js --reject # Reject cookies (where possible)
```

Automatically dismisses EU cookie consent dialogs.

Run after navigating to a page:
```bash
./scripts/nav.js https://example.com && ./scripts/dismiss-cookies.js
```

## Background Logging (Console + Errors + Network)

Automatically started by `start.js` and writes JSONL logs to:

```
~/.cache/agent-web/logs/YYYY-MM-DD/<targetId>.jsonl
```

Manually start:
```bash
./scripts/watch.js
```

Tail latest log:
```bash
./scripts/logs-tail.js           # dump current log and exit
./scripts/logs-tail.js --follow  # keep following
```

Summarize network responses:
```bash
./scripts/net-summary.js
```
