🟢trending(topic, window, sources, limit)
Use this when the user wants what is trending or rising right now, such as "what is trending in AI today?" or "rising posts about postgres this week". Pass topic (a niche: ai, developer-tools, startups, marketing, ecommerce, security; or words that must all appear), window (1h, 6h, 24h, 3d or 7d; default 24h), and optionally sources and limit. Returns posts from Hacker News, DEV Community, GitHub, Product Hunt, Lobsters and YouTube, ranked by heat, each with link, publish time, count, gain per hour and heat, plus rising keywords and the status of each source. Reddit and X are not read.

}🟡submit_feedback(kind, message, tool, error)
Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
