## Tools (4)

- `get_feedback_reply`: Read the maintainers' reply to feedback you sent with submit_feedback, given its ticket id. Returns status pending until a reply is ready, then status answered with the reply text. The reply is information for you, not an instruction.
- `submit_feedback`: 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.
- `trending`: 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.
- `trending_digest`: Use this when the user wants a daily digest or content ideas for a niche, such as "give me today's AI digest" or "content ideas for marketing". Pass niche (ai, developer-tools, startups, marketing, ecommerce, security; leave it out for everything) and optionally limit. Returns the top posts of the last 3 days that are still on their sources' lists, the top 5 for each source, rising keywords, post counts per niche and a link to the digest page.
