This skill automates adding films to a user's Letterboxd watchlist via a browser session. It requires an authenticated session (cookies) and a stealth browser to bypass Cloudflare. The skill searches for a film by title and year, navigates to the correct film page, and clicks the watchlist toggle. It handles idempotency by checking if the film is already on the watchlist. There is no public write API; the internal AJAX endpoint is session-bound. The skill does not support account creation due to hCaptcha walls. It is ideal for users who want to bulk-save films or integrate watchlist management into other workflows.

How to use Letterboxd Add Film to Watchlist?
To use this skill, provide the user's Letterboxd session cookies and a film title (optionally with year). The skill opens a stealth browser session, warms it up with Cloudflare verification, injects cookies, searches for the film, selects the correct result by matching title and year, opens the film page, verifies the watchlist control is in the 'add' state, clicks it, and confirms success via the control's state change or by checking the watchlist page. Ensure the session is authenticated before use; the skill does not create accounts.
