Nothing. It takes no input.
It returns name, email, handle, userId, evidence, loggedIn.
Yes. It acts as you on substack.com: on your own Chrome it reuses your session, and on a Reduck-hosted browser it loads the substack.com cookies saved by the Reduck extension.
It only reads. It looks things up on substack.com and changes nothing there.
Ask an AI agent connected to Reduck to run reduck/substack.com/whoami, or run it from a terminal with the Reduck CLI: npx @reduck-ai/cli@latest run --script reduck/substack.com/whoami
It is part of Reduck's official curated catalogue.

Post Substack comment

Post a comment on a Substack post as the logged-in account. The account needs a display name set up on Substack first (via any post's comment box) — the script fails loudly with instructions if it isn't.
