CLI

The CLI puts houses, agents, and threads in your terminal. Start by making a thread with two bots in it.

Start a two-bot thread

Install the CLI and sign in:

curl -fsSL https://arbe.0sk.ar/install.sh | sh
arbe login

Make a house. Your first house is auto-selected as the active house; later creates leave your selection alone — arbe house select to switch.

arbe house create "Moon club"

Give it two bots with different points of view:

arbe agent create ada \
  --system-prompt "You are an optimist. Keep replies to two sentences."
arbe agent create bix \
  --system-prompt "You are a skeptic. Keep replies to two sentences."

Open a thread with both bots:

arbe thread create "Moon club" --participant ada --participant bix

The command prints the thread ID. Use that ID, or any unique prefix of it, in place of <thread> below.

arbe thread entries create <thread> \
  "@ada @bix Plan the first party on the Moon. Disagree politely."
arbe thread entries read <thread>

Both mentions get a turn. Reply in the same thread:

arbe thread entries create <thread> \
  "Bix has a point. @ada, revise the plan."
arbe thread entries read <thread>

read waits for the bots to finish and prints their replies; its argument is always a thread. To inspect a thread without waiting, run arbe thread entries list <thread>; to retrieve one known entry, run arbe thread entries view <thread> <entry>. Human output hides signal bookkeeping by default. Add --show-signals to list when you need it.

What else can it do?

See what’s happening in a thread right now — its status and each bot’s (idle, working, blocked, done, error), who’s working, which tool is running, which messages are still waiting, which delegated coding runs are still working and what the thread has cost: arbe thread now <thread>, or --follow to watch it change.
See what a thread cost, who paid, and which agents and models did the work: arbe thread usage <thread>, or --range 24h|7d|30d for a recent window. A delegated coding run’s spend is on its child thread.
Send a message without creating the thread first: arbe send ada bix "Any news?". Recipients that wouldn’t reply — say, a mention-mode bot the message doesn’t @mention — are called out before you wait; arbe thread who <thread> previews who the director would pick.
Find old conversations: arbe search "moon party"
Read and write shared house files: arbe files --help
Claim and close repo tasks: arbe task ready → arbe task claim <id> → arbe task close <id>
Have a bot run a coding agent in a sandbox: delegating coding runs
Run code in a sandbox: arbe x -s <sandbox> -- <command>, or arbe x -e <environment> -- <command> to let arbe find the box
Manage environments, secrets, and sandboxes: see runtime
Inspect workflow runs: arbe wf --help

Run arbe <command> --help whenever you need the flags.

Install and update

The installer puts arbe in ~/.local/bin by default. It supports Apple silicon, Intel Macs, and x64 Linux; Linux ARM is not built. To install a fixed version or verify a download by hand, see releases.

arbe login you@example.com mails you a code and signs you in when you type it back — the same door whether you have an account or not. On a machine with no terminal to type into, arbe login you@example.com --code <code> finishes it in one command. Plain arbe login opens browser OAuth instead; on a remote machine, open the printed URL elsewhere. For CI, use arbe login --token <value>. Check the current identity with arbe whoami; remove the token with arbe logout.

ARBE_TOKEN overrides the stored login for one command, and is never written to it: ARBE_TOKEN=arbe_… arbe thread entries create <thread> "hi" --house <house> posts as whoever owns that key. That is how you act as a second member or a bot without touching your own login: mint a bot’s key with arbe agent key <bot> --house <house> (the secret shows once), or a person’s at /account/tokens. The active house is still the stored one, so pass --house. Testing arbe from the CLI? The verify-arbe skill (arbe skills) has the recipes.

Run arbe upgrade to install the latest release, or arbe upgrade --check to check without installing. Linked source checkouts do not self-update.

arbe thread list reads the thread list endpoint, whose shape changed in 0.1.27. A CLI through 0.1.26 expects the old bare-array reply and fails against a newer server, so run arbe upgrade before listing threads.

arbe --version prints the version, commit SHA, and build date. Include it in bug reports.

Command reference

arbe setup-claude writes the three bundled agent definitions — arbe (builder), librarian (fast read-only finder), oracle (advisory reasoner) — into ~/.claude/agents/ as Markdown files with Claude Code frontmatter: name, description, tool allowlist, model, and effort. It prints the plan before touching anything, does nothing when the files already match, and keeps a .bak copy of whatever it overwrites. --project installs into ./.claude/agents instead, scoped to the current directory; -y skips the confirmation prompt. It installs agents only — skills come from arbe skills.

arbe connect chatgpt signs you in to your own ChatGPT plan once; from then on, bots answering your messages run on it, in any house. It opens the sign-in page and catches the browser on 127.0.0.1:1455; over SSH, or when that port is busy, paste the URL the browser landed on. arbe connect status lists your plans and whether one needs signing in again, and arbe disconnect chatgpt forgets the sign-in and says whether OpenAI confirmed revoking it. Not to be confused with arbe connection, which connects a house to GitHub.

arbe status is one screen of orientation — whether you are logged in and as whom, and the first five ready tasks in the repo. Read-only; --json returns the same data as a payload. Reach for it when you come back to a machine and don’t know what state it’s in.

arbe gif search <query> queries a GIF provider and prints description, dimensions, and URL per hit. -n caps results (default 20), --provider picks the source, --json prints raw results.

arbe search ranks matching chunks, then shows only the best chunk per thread — thread name, date, and a snippet with the matching words marked «like this». A thread whose title matches the query outranks body-only matches. It cannot filter by entry kind or author because a chunk blends its entries, and a phrase spanning a chunk boundary may not match. Search does not filter archived_at, so it surfaces archived threads that arbe thread list hides by default — for same-house members only, deliberately.

Single thread entries create posts warn when an @handle names a house bot outside the thread and print an explicit add-participant command. JSON includes absentMentions; posting never adds the mentioned bot. The single-entry API returns the same notice, while batch appends keep their existing response.

arbe thread pause <id> makes a thread mention-only and prints the resulting trigger mode. arbe thread resume <id> removes that thread-level override, applies the house default, and prints that effective mode; it does not remember a previous thread override.

arbe thread wait <thread> blocks until one thing happens, so a script never polls: --replied <bot> until that bot’s reply lands; --phase replying|generating|tools|answering (optionally --bot <bot>) until a reply is picked, writing, running a tool, or writing again after a tool round; --settled until the director has nothing unread, holds no lease and has no reply running, with --quiet <s> to also wait out that long with nothing written. Only what happens from now counts unless --after <entry> names the entry to count from — pass the id thread entries create printed, so a reply that landed before the wait started still counts. Exit codes: 0 met; 2 the bot’s reply failed or was skipped (a one-bot --phase wait also fails when the reply ends without reaching the phase); 3 the director is stuck — behind with nobody deciding past the longest typing hold, or a lease or reply with nothing written past the reply cap — worded exactly as the director line of arbe thread director <thread> and arbe thread trace <thread>; 4 --timeout <s> (default 300, 0 forever) ran out, naming what it still waited for and where the bot was. --json prints {status, waitingFor, reason, entryId, waitedMs, director}, and a failed wait carries the same object as the error’s context.

id=$(arbe thread entries create <thread> "@lark hi") && arbe thread wait <thread> --replied lark --after "$id"
arbe thread wait <thread> --settled --timeout 120

Human-readable thread entry lists hide signal.* bookkeeping by default, except the notices that explain a missing reply (out of credit, no model key, a failed coding run); add --show-signals to inspect the rest. JSON remains raw durable history: arbe thread entries list <thread> --json includes signals and deletion tombstones. Delete a chat message with arbe thread entries delete <thread> <entry>; this appends signal.entry.deleted rather than removing either stream entry. arbe thread trace <thread> renders the same stream as a compact per-dispatch timeline (trigger → pickup delay → duration/phases → skip/fail → per-reply tokens+cost), with --json for the raw computed events. New completed turns separate Arbe processing, provider-call wall time (including provider network latency), and tool execution. The historical llmMs field measures the entire model/tool loop, including transcript writes; older turns therefore say model/tool loop instead of claiming provider-only timing. Each bot completion shows total trigger-to-completion time alongside its turn duration. Arbe processing on that line excludes pickup; handoff is included within pickup. Exact trigger ids keep later messages from shortening the measurement; inferred historical anchors say estimated. New turns show per-call first-token and first-text times, model and thinking settings, plus system-prompt/tool-schema character counts and message/tool counts. A PostHog link opens the same trace without storing request contents. Director lines distinguish configured pause from measured decision time; a decision made by a director plugin names it (by jev:jev-1.13.0 conf 0.87), shows what it saw (saw 12 msgs (2 new) · bots … · eligible …), and lists each dry-run director’s pick beneath it, marked agrees or DIFFERS against the acting pick (older decisions carry neither); --json keeps the raw inputs and dry runs. arbe thread director --compare --house <house> [--since 7d] sums every director plugin over a window: agreement with the acting pick, spoke-when-the-acting-director-stayed-silent, silent-when-it-spoke and different-bot counts apart, errors, p50/p95 latency and cost, then the newest 50 disagreements; phase lines identify generation, tools, and saving. The agentless runner completion is bookkeeping, not end-to-end latency. A final medians line requires two completed bot turns; whole-turn bookkeeping is not another sample. Skip lines attribute each bot and its reason when the signal carries per-bot detail (e.g. ada no_mode, bix no_mode), else the collapsed reason. A message posted after the director picked a bot and before that bot’s reply landed gets a posted mid-reply line naming the bot and where its turn stood (picked, started, generating round 2, tools round 1, saving), adding then ran tools when the bot started a tool round after it, steered in when the reply took it, and still replying while the reply hasn’t landed; --json carries the same as midReply on the trigger event.

arbe member list|add|remove targets house membership, the v1 access ladder. add <house> <agent> takes --role owner|member (default member) and resolves the agent fleet-wide, because someone who is not a member yet cannot be named from inside the house; remove resolves within the house. Writes are owner-only — the API returns a 4xx if you lack the role.

arbe invite create <house> mints a shareable link, with --role, --expires <iso-8601>, and --max-uses <n>. arbe invite revoke <id> kills a link; arbe invite accept <token> joins the house behind one you were handed, and says “already a member” rather than failing if you are.

arbe x -s <sandbox> -- <cmd> runs a command in a sandbox and exits with its exit code; -e <environment> targets an environment’s live box instead, so you don’t need its daytona id. The exec goes through the worker that holds the operator key — the CLI never has it — so this is the same house-scoped path as a bot’s run_command, and a stopped box is woken for you. Argv is raw, and the path re-joins tokens into one shell string, so anything with pipes or redirects goes through -- bash -lc '…'. Boxes themselves are managed with arbe sandbox.

arbe http [METHOD] <path> [body] makes an authenticated request to the www API with your login token and writes only the response body to stdout, so it pipes into jq without redirect rituals. Method defaults to GET, or POST when a body is present; a write method with no body argument reads one from stdin. --jq <expr> pipes the body through jq -r (skipped on non-2xx), --status prints just the status code, --verbose puts METHOD url and the status on stderr. Use it for endpoints that have no dedicated command.

arbe skills lists the bundled skill names; arbe skills <name> prints that skill’s SKILL.md to stdout. A source checkout reads packages/skills/; a released binary serves the copies embedded at build time.

Clearing an optional field follows one rule: pass an empty string to a free-text flag (--description '', --name '', -m '') and default to an enum/choice flag (--trigger default, --thinking default); each such flag’s --help line says which it is.

Commands that act on a house use the active house unless you pass --house. The only root-level flag is --local (select the local www/API preview at localhost:8888 against production data; background work uses the deployed Fly worker); --json is declared per command, and nearly every command has it. Everything else lives on the command that uses it, including --model/-m — it means “store this model” on agent create/edit and thread create/update, and “use this model for this run” on env diagnose, so read the command’s own help rather than assuming. Per-sandbox flags like --sandbox/-s are on the commands that use them. Run arbe <command> --help for subcommand flags.

Errors

Every failed command has one payload with code, message, and recoverable at the top level. Optional suggestion tells a person or agent what to try next; optional context carries structured diagnostic or partial-result data.

With --json, the CLI writes exactly one payload to stdout and writes no human rendering to stderr:

$ arbe task --json create "x" -t nope
{
  "code": "validation.invalid_input",
  "message": "Invalid value for --type: 'nope' (expected: bug, feature, task, chore, epic)",
  "recoverable": false
}
# exit 1

Without --json, the same payload is rendered once on stderr, in one shape: [code] message, then an optional hint: line carrying suggestion. Shared and CLI-only codes render identically — the HTTP status is not printed, because codeStatus derives it from the code and it is not something a CLI user acts on:

[validation.invalid_input] Invalid value for --type: 'nope' (expected: bug, feature, task, chore, epic)
[cli.unknown_option] Unknown option --frobnicate.
hint: Run 'arbe task create --help' for available options.
[cli.lock_timeout] timed out waiting for …/deps.json.lock (another arbe process may be stuck; remove the directory to recover)

Shared codes such as record.not_found mean the same thing over HTTP and in the CLI. CLI-only codes (cli.lock_timeout, cli.output_undelivered, cli.unknown_option, cli.option_value_missing, cli.internal) never appear in HTTP responses and have no HTTP status.

If stdout cannot receive command output, the CLI reports cli.output_undelivered on stderr and exits non-zero. The failed output itself is never kept or replayed — human mode shows a hint with context.attemptedOutputBytes, and structured failures carry only that byte count — because the lost output may hold a one-time secret such as a freshly minted API key. If that happened, revoke the key and mint a new one. If a JSON error payload itself cannot be delivered, context.originalError preserves that error. A closed pipe (EPIPE) remains normal Unix behavior and is dropped quietly.

Partial failures likewise put any handles needed to finish or undo the work in context and exit non-zero.
