Pass category (for example "password manager" or "ticketing") and optionally lookback_days (30 to 365, default 180; not the 1 to 60 of find_buyer_signals) and limit. Return

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 i
