Use the RSSaurus command-line client (Go binary `rssaurus`) to interact with https://rssaurus.com from the terminal: authenticate (`rssaurus auth login/whoami`), list feeds/items, print item URLs for piping, open URLs, and perform triage actions (mark read/unread, bulk mark-read, save/unsave). Use when asked to automate RSSaurus tasks from CLI, debug token/config issues, or demonstrate command usage.
