🟢lection_browser_tools_info(platform)

Explain how to export data from Instagram (comments, followers, following, posts) or LinkedIn (connections) with Lection. These sites require login, so they run in the user's own browser through the Lection Chrome extension rather than inside ChatGPT. Call this whenever the user asks for Instagram or LinkedIn data; it returns the install link and the right tool page.

🔴schedule_extraction(savedScrapeId, name, cadence, timeOfDay, weekday, ...)

Create a recurring schedule (hourly, daily or weekly) that re-runs one of the user's saved scrapes and delivers each run to email, a Google Sheet or a webhook. This creates a recurring job in the user's Lection account and may use cloud credits: confirm the saved scrape, cadence and destination with the user before calling. Respects the user's plan limits and returns a clear message if one is reached.
