Channel commands read the current state first and converge on what you ask
for: repeating a command that has already taken effect succeeds with
changed: false instead of failing or duplicating.
hansa chat channels list # your channels
hansa chat channels browse # public channels you have not joined
hansa chat channels get --channel general # one channel by slug or ID
Creating and changing channels
# Return "Marketing" and create it only if it does not exist yet
hansa chat channels ensure --name Marketing --type public
# Rename or change the type; a no-op when nothing changes
hansa chat channels set --channel marketing --name Marketing EU --type private
# Archive a channel (idempotent)
hansa chat channels archive --channel marketing
References use the backend's slug or ID, never display-name matching. Note that renaming a channel changes its slug — reference the channel by ID in scripts, or re-resolve it after a rename.
Membership
hansa chat channels join --channel general # no-op when already a member
hansa chat channels leave --channel general # no-op when not a member
hansa chat channels members --channel general # list channel members
hansa chat channels invite --channel general --member 42
Direct messages
hansa chat channels dm --member 42
Returns the existing direct channel with that user or creates it; the backend treats this operation as idempotent.
Read state
Reading channels and messages never changes what counts as read. The only command that does is:
hansa chat channels mark-read --channel general
Workspace members
hansa chat members list --query igor # search members by text
hansa chat members get --member 42 # one member by user ID
