arsalanqasim/verity-fact-checker ? reverse-engineered prompt

Build me a Slack bot called Verity that people can mention or paste a link or claim to, and it should reply in the thread with a clear fact check verdict like True, False, Misleading, or Unverifiable.

I want it to handle plain text claims, article links, and YouTube links, pull in live web evidence, and weigh sources so stronger sources count more than random blogs. It should give a short explanation, show the most relevant sources it used, and feel like a trustworthy assistant for spotting misinformation.

Please make it work nicely in Slack with threaded replies, and set it up so it can run locally with Socket Mode. If it helps, look up the current Slack and Brave Search docs online while building it. Keep the code clean, include tests, and make sure the app can be configured from environment variables.
