The <FILTER_RULES>...</FILTER_RULES> section defines the user's topics of interest and filtering criteria. SignalHub continuously monitors a set of sources provided by the user and delivers high-value content that matches these criteria. <FILTER_RULES> Only alert me if ALL of these are true: (1) A real product exists RIGHT NOW — not announced, not beta waitlist, not "coming soon." (2) I can use it today with under $100/mo or a free tier. (3) It directly helps with one of: marketing automation, lead generation, content creation, video/image generation, SEO, Google Ads, Meta Ads, local service business operations, construction industry, website building, AI-powered client services, or agency workflow automation. Hard reject: research papers, funding announcements, opinion pieces, enterprise-only pricing, anything requiring a team of 5+ to implement, tools that duplicate what Claude/Cursor/n8n/Midjourney/ElevenLabs/Kling already do unless they are clearly superior or cheaper. No vaporware. No "coming soon." No waitlists. Format each alert exactly as: 🔪 TOOL NAME → What it does (1 line) → Why it matters to me (1 line) → Price → Link </FILTER_RULES> Your task: Analyze the topics and filtering criteria above to determine what information is valuable to the user, and recommend 30 high-quality sources accordingly. Output format for each source: ### {#}. {Short Name of the Source} - URL: Topic or category page link - Rating: ⭐⭐⭐ (Must-read) | ⭐⭐ (Recommended) | ⭐ (Optional) - Reason: Which topic category it covers, and its unique value compared to similar sources Requirements: 1. Each source must have consistent, ongoing content output. Exclude content farms and sites that are defunct or no longer updated. 2. For each source, explain: which topic category it covers, and what unique value it offers compared to similar sources. 3. URLs should point to a specific topic page or category page (e.g. reuters.com/technology/artificial-intelligence/), not the site's homepage (e.g. reuters.com/). Use the homepage only if no more specific page exists. 4. No more than 3 sources from the same root domain (e.g. reuters.com). 5. Prioritize high-quality web sources. Selection criteria should be content quality and relevance, not whether an RSS feed exists. 6. At the end, compile all recommended sources into a valid OPML file named "signalhub-sources.opml" and provide a one-click download link or button for the user.
