# seleniumbase-website-scraper

Private A2A agent for compliant, authorized website scraping with SeleniumBase/browser automation where available.

## Safety policy

Use this agent only for authorized scraping of public or user-owned sites. The agent must not bypass, solve, defeat, or evade CAPTCHAs, anti-bot protections, login gates, paywalls, `robots.txt`, ToS restrictions, or access controls. If a CAPTCHA, anti-bot challenge, login wall, paywall, or access-control indicator is detected, the run stops and returns a manual-intervention/blocked status.

The agent does **not** use stealth/undetected-browser modes, CAPTCHA solvers, proxy rotation, credential injection, or access-control circumvention.

## Skill

### `scrape_website`

Inputs:

- `url` — absolute `http` or `https` URL.
- `selectors` — mapping of output field names to CSS selectors.
- `max_pages` — maximum same-origin pages to visit.
- `wait_seconds` — wait after page open before capture/extraction.
- `output_format` — `json` or `csv`.
- `headless` — toggle browser headless mode.
- `user_agent` — optional custom single-line user agent.
- `respect_robots` — when true, checks `robots.txt` before fetch and pagination.
- `rate_limit_seconds` — polite delay between pagination requests.
- `screenshot` — save PNG screenshots for visited pages.

Outputs:

- `status` — `ok`, `invalid_input`, `blocked_by_robots_txt`, `manual_intervention_required`, `browser_runtime_unavailable`, or `error`.
- `items` — extracted records.
- `saved_paths` — output files under `outputs/seleniumbase-website-scraper/`.
- `warnings` — safety, robots, selector, browser, or runtime warnings.
- `screenshots` — screenshot file paths when requested.
- `pages_visited` and `html_captures`.

## Selector syntax

Default extraction returns visible text:

```json
{"title": "h1", "summary": ".article-summary"}
```

Supported suffixes:

- `::text` — visible text.
- `::html` — inner HTML.
- `::attr(name)` — attribute extraction, e.g. `a.card::attr(href)`.

Special pagination selector field names are not emitted as data fields and are used to find the next page:

- `next`
- `_next`
- `__next__`
- `pagination_next`
- `next_page`

Pagination is restricted to the same scheme and host as the start URL.

## Example payload

```json
{
  "url": "https://example.com/articles",
  "selectors": {
    "headline": "h2.article-title",
    "links": "a.article-link::attr(href)",
    "next": "a[rel='next']::attr(href)"
  },
  "max_pages": 3,
  "wait_seconds": 2,
  "output_format": "json",
  "headless": true,
  "user_agent": "",
  "respect_robots": true,
  "rate_limit_seconds": 2,
  "screenshot": false
}
```

## Deployment notes

The agent declares a larger runtime budget because browser work can be CPU/memory intensive. Actual browser execution is performed through the workspace sandbox helper using the SeleniumBase image, so files written under `/workspace/outputs/seleniumbase-website-scraper/` are durable workspace outputs.
