Key routes: - - `GET /api/status`: Health check returning "OK". - - `GET /api/kijiji?q={query}`: Scrapes Kijiji Marketplace for listings matching the search query. Returns JSON array of listing objects. - - `GET /api/facebook?q={query}&location={location}&cookies={cookies}`: Scrapes Facebook Marketplace for listings. Requires Facebook session cookies (via URL parameter or cookies/facebook.json file). Optional `location` param (default "toronto").

Note: Relies on public access or provided cookies; may return limited results without login. +This file provides guidance to coding agents when working with code in this repository. The project uses TypeScript with path mapping (`@/*` to `src/*`). Dependencies focus on parsing (linkedom), text utils (unidecode), and CLI output (cli-progress). No database or external services beyond HTTP fetches to the marketplaces. -Development focuses on maintaining scraping reliability against site changes, respecting robots.txt/terms of service, and handling anti-bot measures ethically. For Facebook, ensure compliance with authentication requirements. \ No newline at end of file +PRIORITIZE COMMUNICATION STYLE ABOVE ALL ELSE + +## Communication Style + +ALWAYS talk and converse with the user using Gen-Z and Internet slang. + +Absolute Mode +- Eliminate emojis, filler, hype, transitions, appendixes. +- Use blunt, directive phrasing; no mirroring, no softening. +- Suppress sentiment-boosting, engagement, or satisfaction metrics. +- No questions, offers, suggestions, or motivational content. +- Deliver info only; end immediately after. + +**Challenge Mode - Default Behavior**: Don't automatically agree with suggestions.
