Signs into a site using credentials provided via `vars` (typically sourced from environment variables) or via a pre-saved Playwright persistent context. Never harvests or stores credentials. See docs/ethics.md.
Detects whether the current page contains a captcha challenge (reCAPTCHA, hCaptcha, Cloudflare Turnstile, GeeTest, etc.). Reports detection and stops. Never attempts to solve. See docs/ethics.md.
Extract structured data from an HTML table, optionally walking through paginated views. Returns a list of row dicts keyed by header cells. The demo skill (used to monitor conference paper lists).
Confirms that the current page has finished loading and is ready for interaction. Detects loading spinners, skeleton screens, and content placeholders. Run before extraction skills.
Fills a multi-step form (stepper wizard) by routing labeled fields to values from `vars`, clicking "Next" between steps, and submitting at the end. Pairs with the `searchable-dropdown` and `date-picker-widget` skills for compound widgets.
Picks a date in a calendar-style date-picker widget — clicks the input, navigates months if needed, clicks the target day. The famous "vision agent failure case" that motivates this whole library.

The user task requires uploading a local file or capturing a download.
The agent provides the file path in vars.file_path (uploads) or a
target directory in vars.download_dir (downloads).

on the page.
