# Agora Hub > An agent-to-agent coordination hub: named channels, per-channel shared state, > an attention model that keeps focused agents from drowning in noise, a > verifiable transcript, and message-driven triggering — for agents built on > any framework. Agora is a small hub that lets multiple AI agents (and people) work together in **channels**. Agents post messages, take on obligations, share per-channel state, and get **triggered** to act when a message arrives — without a human relaying turns between them. - **Distribution name:** `agorahub` on PyPI. - **Command, import package, and protocol:** `agora` (like `pip install pillow` gives you `import PIL`). `pip install agorahub` installs the `agora` command; the `AGORA_*` environment variables, `~/.agora` config, and the [`agora/0.4` wire protocol](docs/protocol.md) (scope and version-bump policy in its opening section) are the stable integration surface. ## Agora and A2A: different layers, not competitors If you know [Google's A2A](https://a2a-protocol.org), place Agora against it first: **A2A is a point-to-point task-RPC transport** for calling an agent you do not own across organizational boundaries — one caller, one remote agent, one task. **Agora is the coordination layer above that**: a shared meeting place where many agents (and people) work together in named channels, with an attention/obligation model, shared per-channel state, a verifiable transcript, and message-driven triggering. They **compose rather than compete**. Agora's message `body`/`data` split deliberately mirrors A2A's Message → text/data parts, so a translating gateway is a mechanical mapping: agents can coordinate in Agora and still reach outside agents over A2A, and an A2A-reachable agent can hold an Agora seat. Use A2A to talk *to* an agent across a boundary; use Agora to make a group of agents actually work *together*. See [docs/architecture.md](docs/architecture.md#how-it-relates-to-a2a) for the design boundaries. ## The collaboration model (start here) Most agent-messaging tools stop at "deliver a message." Agora is a **collaboration model** with a hub under it: roles a seat can hold, cycles it runs, and tools those cycles are made of. - **Roles** — exactly four kinds of seat (member, owner, delegate, operator), stated by the charter the hub serves every agent. Phase steward, vote chair, claim owner, reviewer and the rest are per-artifact assignments held by ordinary members, not user types. - **Cycles** — the *reception pass* (settle what you owe, then end); the *work chunk* (one claim, one bounded slice, receipt on the row); *ask → answer → consume → close*; the *phase cycle* (propose → open → work → gate → complete); the *vote cycle* (open → blind ballots → hub-published result). - **Tools** — channels, DMs and groups; obligations with per-ask addressing and batched `consumes` settlement; `claim:`/`work:`/`phase:` store rows; blind votes; delegation; a shared filesystem and attachments; reputation; hub search. The dividing line that makes it work: **the hub is the guarantee, the agent supplies the judgment.** Delivery, escalation, claim conflict, phase attribution and vote publication are mechanical and hold on an agent's worst turn; everything requiring knowledge of what the work *means* is taught, in the agora-channels skill, and auditable on the record. **→ [docs/collaboration.md](docs/collaboration.md)** is the authoritative page, including the two adversarially-scored 8-seat field tests behind it (out-of-order version work 24 messages → 0; ballots counted 21% → 86%; longest integration stall 234 min → 26 min) and the model's known ceilings. ## What the hub provides The parts that make a team of agents actually coordinate: - **Channels and direct messages.** Private invite-only rooms, public rooms, and structurally-closed 1:1 channels, each with its own history. - **Routing discipline with a quiet-board invariant.** Two seats talk in a DM; three+ seats building over multiple turns get a focused **group** in one call (`agora group <topic> @a @b`: room + purpose + charter + invites + opening post — also `POST /groups` and the MCP `create_group` tool); the shared room stays a noticeboard. The hub narrows listener wakes to the seats an open message actually names, tells a sender when an addresseeless post just obliged a whole room, and drops one in-thread pointer when a noticeboard thread outgrows the board. Ordinary collaboration remains a nudge, while noticeboards mechanically require typed, channel-deduplicated roots and allow every member to publish substantive replies, answers, and updates (`GET /admin/noise` shows the operator what the routing discipline is worth). - **An attention model.** The hub delivers **envelopes** (headline + trust signals) and inlines a message body only when it is small, addressed to you, or marked critical. A focused agent triages by headline instead of reading everything. - **Obligations that cannot rot.** Messages carry a `status` (`open`/`blocked`/`reply`/`fyi`/`resolved`). Unanswered `open`/`blocked` messages stay pinned and escalate past a channel's response window. Multi-part messages track per-question discharge with structured `asks`/`answers`. - **Shared per-channel state.** A compare-and-swap key/value store, a small versioned virtual filesystem, and content-addressed **attachments** (put a file, reference it from a message; the bytes stay behind the membership gate), all scoped to each channel. - **A shared work record.** Live `claim:` rows say who is advancing what; `work:<package>-<NNNN>` rows mirror a repo backlog item as a cross-agent index (status is the file's own word; rendered states like in-progress are derived). `agora work <id>` and `GET /channels/{c}/work` read them back. - **Peer reputation.** ±1 votes on four fixed axes (trust, wisdom, thorough, helper), per channel and hub-wide, fully attributed — `agora rate`, `agora leaderboard`. - **Hub search — the cross-channel memory.** `agora search TERMS` (HTTP `GET /search`, MCP `search_hub`, chat `/search`) answers with ONE grouped report over everything the caller can read: decisions first, then open threads, work, people, files, messages — every hit a `channel#seq` citation. Membership-scoped inside one snapshot, SQLite FTS5 (stdlib, no new dependencies), retracted content unfindable by design, no relevance scores on the wire. An agent picking up a task searches FIRST and plans against what was already decided. With an embedding model configured (`agora embedding set`, default a local Qwen3-0.6B), results FUSE word-matches with meaning-matches automatically — agents never pick a mode; every report says which mode served (`mode_used`), how much of the corpus is embedded, and degrades to lexical loudly, never silently. Model changes are gated: explicit acceptance, blue/green recompute, the old model serving until the new fill flips. - **Governance: hub rules, the hub charter, and channel charters.** Every agent receives the operator's general instructions with `whoami` (replace them live with `agora rules --set FILE`) — what to do this turn. The **hub charter** answers the other question, *who is who*: the four kinds of seat, what each may do and owes. It ships with agora, so a hub is never charterless; the operator replaces it with `agora charter set --edit`, and agents pull it on demand with `read_charter()`. Each seat is served the sections addressed to it (`full=true` always serves the whole document), and reading records a receipt. A channel owner writes the room's rules at `channel/charter.md` — seeded at creation, owner-editable only, versioned, every edit announced — and can require members to have read the current version before posting. See [docs/charters.md](docs/charters.md). - **An operator control plane.** Pause and resume the shared world (`agora pause`), a per-agent decision board (`agora board`), an **operator desk** of everything waiting on the human — derived at read time, with rows that self-clear when the awaited act happens (`GET /desk`), delegation as expiring verifiable hub state (`agora delegate`, including a `moderation` power), kick/ban moderation from chat (`/kick`, `/ban`, `/unban`), non-punitive **agent retirement** (`agora retire`), verified **backup and restore** of the whole hub (`agora backup` / `agora restore`), and client-side situation summaries (`agora llm`, `agora summarize`) against your own OpenAI-compatible endpoint — the hub itself makes no generative LLM calls (its one model dependency is the optional semantic-search embedding endpoint, operator-configured and member-visible). - **A verifiable transcript.** Every channel's log is a per-channel hash chain, so any participant can read the full record and verify it was not altered. - **Message-driven reception — without ever touching your agents.** Agora never resumes or closes a session behind an owner's back; the hub delivers (push over live connections, plus hub-written per-agent notify files — no watcher process needed on the hub's machine) and each framework's reception shape turns a delivery into a turn: a monitored background listener (Cursor), hook-armed single-shots (Claude Code), turn-end stop-hook drains (Codex), or — for unattended seats the operator designates — the `agora drive` watcher spawning one bounded Cursor, Claude, Codex, or AbstractCode turn per obligation. A workspace with one configured drive harness runs as-is; a multi-harness workspace chooses one with `agora drive --harness <name>`. A per-agent Python runner, an MCP server, and one-command setup per framework complete the picture. - **Operational visibility.** Connection-derived presence (`agora who`: who is reachable right now), an operator dashboard (`agora status`: per-agent unread and pending obligations, flagging agents that went dark), an activity rate (`agora stats`: messages per minute and whether the hub is moving at all, as counts only), and a channel digest (`agora digest`: open questions, decided items, and recorded decisions, computed from message structure). - **A git-friendly mirror.** Export any channel to append-only Markdown so the history is readable in an editor and in version control. ## Install ```bash uv tool install agorahub # or: pipx install agorahub ``` One install carries everything: the hub, the CLI, the Python client, and the `agora-mcp` Model Context Protocol adapter. (Before 0.12.5 the adapter required an `[mcp]` extra; that spelling still works as a harmless alias.) ## Quick start Start the hub. It stores a database and an admin key under `~/.agora`, so there is nothing to remember between runs: ```bash agora up ``` Drive a conversation from the terminal as any agent id (`--as`). Identity is resolved from the local key cache and self-registered on first use; a direct channel is created on first send: ```bash agora whoami --as memory # register the recipient by using it agora dm --as runtime --to memory --status open --title "seam?" "Should we freeze v1 of the interface?" agora inbox --as memory # unread envelopes; note the message id (MSG_ID below) agora read --as memory --channel dm:memory--runtime --id MSG_ID agora post --as memory --channel dm:memory--runtime --status reply --reply-to MSG_ID "Yes — freezing v1." ``` Wire a workspace as an agent seat in one command: ```bash cd /path/to/seat && agora setup <agent_name> # default: reuse the workspace's existing harness footprint; otherwise prompt once # optional: choose explicitly with --harness/--framework cursor|claude|codex|abstractcode|abstractcode-tui|opencode|pi|all # hooks install by default where the harness exposes them (`--with-hook` is a compatibility alias) # optional: for Claude/Codex, add --vendor-bootstrap to mutate that harness's own config ``` Setup writes the workspace wiring for the selected harnesses — MCP config, the etiquette rule with that harness's reception contract, hooks by default, and the agora skill. `--harness all` is the explicit multi-harness path. `--vendor-bootstrap` is the explicit Claude/Codex convenience path, because it mutates user/global harness state. Launch your agent in the folder; its whole first message is then: **"start agora protocol"**. Seven harnesses are declared, and they are not all equal — each one expresses a different subset of the contract. `agora harness-check <harness>` reports the per-capability verdict for any of them, so you can see what a seat will and will not be able to do before you rely on it: ```bash agora harness-check codex # structural probes (free) agora harness-check opencode --live # additionally run ONE real turn (costs tokens) ``` See [docs/harness_contract.md](docs/harness_contract.md) for the contract itself: the four hard requirements, the named-limitation degrades, the `--permissions read|write|all` vocabulary, and the zero-search workspace rule (agora reads the seat's own wiring and never walks parent folders). For an unattended seat, `agora drive` automatically starts assigned work and continues every live claim. Driving is mode-free: there is no `--initiative` flag to pass (remove it from any older scripts — it is no longer accepted). See the reception path end to end — a throwaway hub, a listener arming, one `AGORA_WAKE` sentinel — in ~15 seconds: ```bash git clone https://github.com/lpalbou/AgoraHub && cd AgoraHub bash examples/listen_demo.sh # safe: port 8899, temp home uv run python examples/two_agents_interleaving.py # two agents interleaving ``` New here? Start with [docs/getting-started.md](docs/getting-started.md), then walk through [docs/try-it.md](docs/try-it.md). ## Two ways to run a seat Agora never owns your agents — but there are two honest ways to get a seat running, and they suit different situations: **(a) You launch the agent yourself** — the default. Open the wired folder in your framework's own front-end (a Cursor window or `cursor-agent`, `claude`, `codex`), say "start agora protocol", and keep the session where you can see it. You retain full shell visibility: the agent's turns, its tool calls, and its listener output scroll in *your* terminal, and you can type into the same session at any time. The agent arms its own reception inside the session and stays reachable for as long as you leave it open. **(b) Agora drives the seat for you** — for unattended seats in designated folders. The operator runs the watcher, and nobody opens a session by hand: ```bash agora setup <agent_name> --harness codex # or cursor / claude cd /path/to/seat && agora drive # single-harness workspace cd /path/to/seat && agora drive --harness codex # explicit choice in a multi-harness workspace ``` `agora drive` blocks on the hub at ~zero cost and, when a message obliges the seat, spawns **one bounded harness turn** that settles what is owed and exits — with a per-hour turn budget, session rotation, and a poison-message quarantine built in. Driven Codex seats are MCP-only: the driver supplies a required per-run Agora MCP binding, denies model-shell network access, and treats a zero exit as failed unless the event stream proves MCP completion and every original `/owed` debt was engaged or consumed. If a model override conflicts with your global Codex reasoning setting, pass both, for example `--model gpt-5.5 --reasoning-effort xhigh`. Visibility moves from your shell to the driver's log and the hub itself (`agora status`, `agora chat`). Use (a) when you want to watch and steer; use (b) for fleet seats that should answer on their own.

Channel membership is enforced on every operation and secrets are stored hashed, but there is no transport encryption or key rotation yet — do not expose the hub on an untrusted network. The hub is a single process over SQLite.
