A gold-markets newsletter automation in Claude Code, built on the WAT framework (Workflows, Agents, Tools). I give it a gold topic and it emails a branded, fact-checked briefing end-to-end: pulls real gold price + volatility from a broker (never invents a number), runs two Perplexity passes (news drivers + social pulse from X/YouTube/Reddit), has Claude write the copy grounded in sources, renders a real price chart, and sends a branded HTML email archiving every paid call. (screenshots attached) 💡 One thing I learned Perplexity isn't just web search with domain filters it searches social media too (X, YouTube, Reddit), so I get real sentiment, not just news. GPT Image Gen 2 (via kie.ai) also felt more capable than Nano Banana. Two gotchas: emails clip above ~102 KB, and phone dark mode breaks a plain black/white logo (the background flips but the logo doesn't). 🔧 One thing I'd improve Be more specific in my prompts. Vague asks gave output that missed what I pictured the more concrete detail I gave, the closer it landed. Next time: lead with precise requirements, not vague direction. #AISChallenge
