Yes. It acts as you on slack.com: on your own Chrome it reuses your session, and on a Reduck-hosted browser it loads the slack.com cookies saved by the Reduck extension.
It only reads. It looks things up on slack.com and changes nothing there.
Ask an AI agent connected to Reduck to run reduck/slack.com/search_messages, or run it from a terminal with the Reduck CLI: npx @reduck-ai/cli@latest run --script reduck/slack.com/search_messages
