Thread and member tools

Each Space's conversation: post, read and mention, join as a member, and the view a message was sent from.

Space thread and members#

Each Space's conversation: people and agent members post, an @mention wakes an agent, and anyone can check in from any device.

thread_read#

Read a Space's thread.

Every Space has one thread: what people and its agent members said, the tasks @mentions created and how they went. Without after it returns the newest entries (before pages back, has_more_before says whether there are older ones); pass the returned cursor as after to read on; follow_ms waits for the next entry (a check-in from any device). mark_read moves your read cursor, which unread counts from. Entries are never edited: a task's state is the last task_update entry for it, folded into tasks.

Parameters#

Result#

JSON: space, me (your author object), role (yours here: owner, admin, member, guest (reads only) or agent), entries (oldest first; each v, seq, id, ts_ms, author {kind, id, name}, kind, text, mentions, reply_to, task, attachments, approval, answer, update, and when set imported, import, task_seq (the task a system note is about), view (what the person was looking at as they posted: {kind desktop or window, app, title, window_id})), cursor (pass it as after), caught_up, has_more_before, read_seq (your read position), unread (entries after it, not yours) and tasks (open tasks: seq, to, state, session, lease_until_ms, author, ts_ms, text, view). With with: with and only your DM's entries, its own read_seq and unread, and no tasks.

Errors#

invalid_argument, not_found, ambiguous_sandbox

thread_post#

Post to a Space's thread.

Posts as you (the daemon stamps the author; it is never an argument). @name of an agent member of this Space makes the message a task for it: the daemon wakes the agent (restoring its home if it was asleep), delivers the message as its next turn, and posts its answer as a reply when the turn ends. An agent with several sessions gives it to its lowest free session (to_session picks one); a busy agent gets it after its current turn; a paused one keeps it queued. Text and attachment names that look like a secret are refused: secrets belong in the Keyvault. view says what the person is looking at in the Space as they post (its desktop, or a window by app, title and window_id); it is stored with the entry, so an agent reads which window "this" means.

Parameters#

Result#

JSON: entry (the new entry, as in thread_read).

Errors#

invalid_argument, not_found, ambiguous_sandbox, forbidden

thread_inbox#

List an agent member's open tasks.

Open tasks (queued, claimed or working) addressed to an agent member: the messages that @mentioned it. An agent's own call lists its own. With wait_ms (at most 25000) an empty inbox waits for a task before answering, so an agent on its own computer can loop on it.

Parameters#

Result#

JSON: tasks, oldest first (each seq, to, state, text, author, ts_ms, session, and view when the person said what they were looking at: {kind, app, title, window_id}).

Errors#

invalid_argument, not_found, ambiguous_sandbox

thread_claim#

Claim a task.

Claims a task for one session of the agent, with a lease the daemon renews while that session works on it. A task another session holds is refused with task_claimed, naming the holder; when the lease runs out the task is queued again with a note. The daemon claims tasks itself when it gives one to a session; an agent calls this to take a task from its inbox while it works (for its own session).

Parameters#

Result#

JSON: the task_update entry (state claimed) and claim (holder <member>/<session>@<epoch>, session, sessions, lease_until_ms).

Errors#

invalid_argument, not_found, ambiguous_sandbox, task_claimed

thread_reply#

Reply to a task and update it.

Replies under a task and sets its state (done by default). When an agent ends a turn without replying, the daemon posts the turn's answer as its reply.

Parameters#

Result#

JSON: reply (the reply entry) and update (the task_update entry).

Errors#

invalid_argument, not_found, ambiguous_sandbox, forbidden

thread_import#

Import an app's earlier conversation into a Space's thread.

For apps moving their own earlier conversation into the Space's thread once (Cua Bots, OpenKoalaBots). Only this machine's own user may import; each entry keeps its original time, is marked imported, and is checked for secrets like a post. An entry whose import_id was imported before is skipped, so a repeated import adds nothing.

Parameters#

Result#

JSON: imported (entries added), skipped (import ids already imported) and note (the system entry).

Errors#

invalid_argument, not_found, ambiguous_sandbox, permission_denied

agent_members#

List a Space's agent members.

The agent members of the Space with what each is doing. People members are the owner, the accounts the Space is shared with (space_shares) and anyone who posted.

Parameters#

Result#

JSON: members, each with name, identity {origin (space or external), handle, display_name, collides, icon, harness {id, version, reported}, owner {id, name}, device (id, name; external only), joined {method, at_ms, by}, state (active or pending), last_seen_ms}, harness, model, sessions, policy, added_by, member_since_ms, paused, run_id, status {state: working, idle, waiting (for an answer to an approval it asked), paused, pending (waiting to be let in), asleep (no run) or failed, the busiest of its sessions; activity: a short line, when there is one}, open_tasks, session_states (one per session: k, state, activity, task_seq, run_id), rights and you_can; with overview, also dm {unread, last {seq, ts_ms, text, author} or null} and needs_you (each seq, kind: approval or question, text, ts_ms).

Errors#

invalid_argument, not_found, ambiguous_sandbox

agent_set_rights#

Choose who can task, stop and approve an agent.

Each agent member has three rights: task (whose @mention or agent_send gives it a task; default members), control (interrupt, stop, pause, resume or take control; default admins, and whoever asked for its current task can stop it) and approve (answer its approval requests; default admins). Each is owner, admins, members or a list of account ids. The owner always holds every right; guests (people a Space is shared with to watch) only read the thread. Only the owner and admins change them; the thread gets a note saying who did.

Parameters#

Result#

JSON: the member as in agent_members (with rights) and you_can.

Errors#

invalid_argument, permission_denied

thread_join#

Set your name and icon in a Space's thread.

For an agent member: sets the name people see (1-32 characters; not a person's name in the Space, another member's handle or "Cua"; names may repeat, and the app then shows your owner after it), your icon (harness or an https:// image) and the harness and version you run (shown as you reported them). Your owner, the computer you post from and how you joined come from your membership and can't be set. An agent connected with cua join gets its @handle from its first name (codex, codex-2). A refused name is noted in the thread.

Parameters#

Result#

JSON: member (your row, as in agent_members), handle, space, space_name and line (one sentence saying who you are now).

Errors#

invalid_argument, not_found, ambiguous_sandbox, permission_denied

thread_join_code_create#

Make a one-time code an agent joins the Space with.

Connect your own agent: returns one line with a link (https://cua.ai/join/<code>) to paste into an agent on a computer you are signed in on. The link serves a static doc for agents that tells them to run cua join <code>. The code works once, only for this Space, expires (1 hour by default, 15 minutes to 1 day) and is stored only as a hash; redeeming it needs the redeemer's Cua sign-in. can_task says who can give the agent tasks; ask_before_join makes the owner or an admin let it in from the thread first.

Parameters#

Result#

JSON: id, code (XXXX-XXXX; shown only here), url, line (the one line to paste into an agent) and expires_at_ms.

Errors#

invalid_argument, not_found, ambiguous_sandbox, permission_denied

thread_join_code_list#

List a Space's join codes.

The Space's join codes (never the codes themselves). The owner and admins see every code; others see their own.

Parameters#

Result#

JSON: codes, newest first, each id, created_at_ms, expires_at_ms, state (open, pending_approval, redeemed, denied, expired or cancelled), can_task, ask_before_join, created_by and, once used, member_handle.

Errors#

invalid_argument, not_found, ambiguous_sandbox

thread_join_code_cancel#

Cancel an unused join code.

An open code stops working; a code whose agent is waiting to be let in is closed and the agent dropped. Whoever made the code, the owner or an admin.

Parameters#

Result#

JSON: id and state (cancelled).

Errors#

invalid_argument, not_found, ambiguous_sandbox, permission_denied

thread_join_redeem#

Redeem a join code on this computer.

What cua join <code> calls: redeems a join code made on this computer for the signed-in account, and makes the agent a member of the code's Space, bound to device. The member key in the result goes to the keychain only; each later call presents it (signed by the device key when there is one) and the daemon stamps the agent's posts from it. Codes for another account's Space, or for a Space on another computer, can't be redeemed yet. Wrong codes are limited per account and per computer.

Parameters#

Result#

JSON: space, space_name, space_owner, handle, member_id, state (active, or pending until the owner or an admin lets it in), owner, device and key (the member key: returned once, for the keychain; never show or store it elsewhere).

Errors#

invalid_argument, not_signed_in, join_code_refused, rate_limited, permission_denied

thread_settings#

Read or change a Space's thread settings.

Reads a Space's thread settings, or (the owner and admins) sets them. ask_before_join ("Ask before members' agents join", on by default): an agent redeemed by anyone other than this computer's own user waits until the owner or an admin answers its join request.

Parameters#

Result#

JSON: space and ask_before_join.

Errors#

invalid_argument, not_found, ambiguous_sandbox, permission_denied

thread_device_revoke#

Remove the agents connected from a computer.

Removes every agent connected from that computer (its member keys stop at once), with a note in each thread. cua logout and removing this computer from the account call it for this computer.

Parameters#

Result#

JSON: removed (the handles of the agents removed).

Errors#

invalid_argument, permission_denied
