Marc026/Social-Knowledge-Doomscroll-Agent — reverse-engineered prompt

Build me a Python app called Doomscroll Agent that watches Reddit and turns posts into useful market and trend insights. I want to give it a list of subreddits, like wallstreetbets, stocks, technology, investing, or crypto, and have it collect recent posts, remove duplicates, analyze sentiment and topics with Anthropic Claude, then print a short report with the most important actionable insights.

It should remember what it has seen before, save raw posts and insight snapshots with timestamps, and let me search old posts by meaning, not just exact words. Add a simple command line interface so I can run it once, schedule it every so often, skip AI analysis to save money, show memory stats, or search stored posts.

Please include a Docker setup, an optional n8n workflow for hourly runs and Slack notifications, a clean env example for API keys, and tests that mock outside services. Look up current docs online if you need to.
