edstem activity lists your own recent activity — threads, answers and comments — across one unit or every unit you’re enrolled in.
edstem activity with no <unit> returns activity across every unit you’re enrolled in. Passing <unit> scopes it to that one unit; <unit> resolves the same way it does everywhere else — see Units.
--filter accepts all, thread, answer or comment. The CLI doesn’t check this value itself — a value outside that list is rejected by Ed, not by the CLI.
Scripting this or wiring it into an agent? See Ed Discussion CLI for scripts and agents.
