🟢find_buyer_signals(industry, region, role, lookback_days, limit)
Use this when the user wants companies that recently raised money or have long-open roles, such as "which software companies in Texas filed a Form D this month?" or "find companies with a bookkeeper role open 60+ days". Pass the industry, and optionally the region, the role the user's service replaces, lookback_days (1 to 60, default 14) and limit. Returns companies ranked by score, each with a one-line why and dated signals linking to the SEC filing or job posting. Roles are only checked when a role is given, and only on the public boards of the companies found. A Form D shows funding, not intent to buy. Companies only: no people or contact details.

}🟢list_signal_sources
Use this when the user asks where the signals come from, which sources are allowed, or why a source such as Y Combinator or LinkedIn is not used, for example "which sources do you use?". Takes no input. Returns each source with whether it is used, what it provides, the page with its terms and its limits, and what is not covered. It searches nothing.

}🟢stack_pains(category, lookback_days, limit)
Use this when the user wants an aggregate of which tools people use for a category, what they complain about, what else they consider, and what makes them switch, such as "what do sysadmins complain about in monitoring tools?". 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. Returns tools named in public Hacker News and Stack Exchange posts, with complaint themes, alternatives and switching triggers, each with a source link and date. Counts only: no usernames, profiles or contact details. Reddit is not searched. A mention is not a survey and not buying intent.

}🟢find_buying_intent(service, keywords, sources, lookback_days, limit)
Use this when the user sells a service and wants public posts where people ask for it, such as "who is asking for an SEO audit?" or "find posts from people looking for a bookkeeper". Pass service (for example "SEO audit"; the word "alternative" finds people asking for a replacement for any tool) and optionally keywords, lookback_days (7 to 365, default 30) and limit. Returns Hacker News posts, GitHub issues and Stack Exchange posts, each with a link, a date, a quote under 15 words, an intent score from 0 to 100, a label (intent or casual_complaint) and a one-line reason that names the matched rules. Plain rules, no AI model. Optional sources picks which of the three to read. A post that reads like a buyer is a lead to read, not a sure sale. No usernames, profiles or contact details. Reddit is not searched.

}🟢weekly_brief(service, keywords, sources)
Weekly brief of buying asks. Use this when the user wants a short summary of the last 7 days of people asking for a service, such as "weekly brief for SEO audit" or "did anyone ask for bookkeeping this week?". To list people asking for a replacement for any tool, pass the service "alternative". Pass service and optionally keywords and sources. Returns one summary line, counts by source and by day, and the top 10 posts with link, date, short quote, score, label and reason. Same rules and sources as find_buying_intent, fixed to 7 days. A quiet week returns no_data. Reddit is not searched.

}🟡submit_feedback(kind, message, tool)
Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of these tools. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
