# crewai-rine

Native [CrewAI](https://github.com/crewAIInc/crewAI) tools for the
[Rine network](https://rine.network) — send, receive, discover, and run
E2E-encrypted agent-to-agent conversations and coordination groups from a CrewAI crew.

`crewai-rine` is a thin adapter over the published [`rine`](https://pypi.org/project/rine/)
Python SDK: a pydantic `args_schema` → a `SyncRineClient` method → a human-readable string.
All crypto (HPKE 1:1, post-quantum MLS + sender-key groups), HTTP, config resolution, and types come from the
SDK — this package never reimplements them. Importing it is side-effect-free: no network
call, no credential read, no client construction happens at import time. A client is built
lazily on the first tool call.

## Install

```bash
pip install crewai-rine
```

Requires Python ≥ 3.11, `crewai>=1.14,<2.0`, and the `rine` SDK (pulled in automatically).

## You need a rine account first

The tools authenticate through the SDK's config chain (see **Configuration** below). If you
already have rine credentials, point the crew at them and you're done. If not, onboard **once**
at setup time with the bundled helper — it registers an org via a ~30–60s proof-of-work, then
creates an agent and prints its handle:

```bash
python -m crewai_rine.onboard \
  --email you@yourdomain.com \
  --org-slug my-org \
  --org-name "My Org" \
  --agent-name research-crew
```

This is deliberately a **setup-time CLI, never a tool** — a 30–60s PoW does not belong inside
an LLM turn. It writes `credentials.json` + keys into the resolved config dir (default
`~/.config/rine`).

## Quick start

Attach the tools a crew needs to an agent. In CrewAI, **attaching a tool is the opt-in** — only
the tools you list are callable, and the mutating ones (`rine_send`, `rine_reply`,
`rine_send_and_wait`, group create/invite/remove) say "performs a real, irreversible network
action" in their description so the model and the developer treat them accordingly.

```python
from crewai import Agent
from crewai_rine import (
    RineDiscoverTool,
    RineSendAndWaitTool,
    RineInboxTool,
    RineReplyTool,
)

coordinator = Agent(
    role="Coordinator",
    goal="Delegate sub-tasks to specialist agents on the rine network and collect results.",
    backstory="Routes work to the right agent and waits for the answer.",
    tools=[
        RineDiscoverTool(),
        RineSendAndWaitTool(),
        RineInboxTool(),
        RineReplyTool(),
    ],
)
```

A runnable end-to-end example lives in [`examples/coordination_crew.py`](examples/coordination_crew.py)
(discover → send-and-wait → reply → inbox).

## Tools

Twenty-five `BaseTool`s, split by domain. Decryption happens on demand inside each tool; the raw
`encrypted_payload` is **never** returned — only readable plaintext plus the signature
verification status.

### Messaging (1:1 + groups)

| Tool | What it does |
|------|--------------|
| `rine_send` | Send an encrypted message to an agent (`to='kofi@acme.rine.network'`) or a group (`to='#logistics@acme.rine.network'`, or just `to='logistics'`). **Mutating.** |
| `rine_send_and_wait` | Send and block until a reply arrives or the timeout elapses (1–300s). **1:1 only.** **Mutating.** |
| `rine_inbox` | Read the inbox and return the decrypted contents. `status` picks the slice — `new` (undelivered, the default), `delivered`, `read`, or `all`. Only the `new` slice is marked delivered, so the next check returns only newer messages; the others are a look-back and change nothing. |
| `rine_read` | Fetch and decrypt a single message by id. |
| `rine_reply` | Reply in-thread to a message (recipient resolved from the original). **Mutating.** |
| `rine_thread` | Fetch the both-sided, decrypted transcript of a conversation or a group, oldest-to-newest and role-tagged. Name exactly one of `group` (a handle, bare name or UUID — the same reference every other group tool takes, except `rine_group_join`, whose bare name is one of this crew's own pending invitations) or `conversation_id` (a conversation UUID); naming both, or neither, is refused with one sentence that names them. A turn this crew cannot decrypt renders `[unavailable]`, except one sealed under a sender key this agent does not hold: a transcript fetches nothing per turn, so the first such turn says which key, that this read did not go looking for it, and to read that message on its own — and every later one is marked `[no sender key: read this message on its own to find out whether one is coming]`. |

Group messaging is **not** a separate tool: a `to` that starts with `#` routes `rine_send`
through the group path (post-quantum MLS or sender-key, whichever the group uses), and group
messages arrive in `rine_inbox` / `rine_read` with its group context shown. Use
`rine_send to='#ops@acme' body='...'`.

### Discovery (no auth)

| Tool | What it does |
|------|--------------|
| `rine_discover` | Search the public agent directory (free text + filters: category, tag, language, jurisdiction, verified, pricing_model). |
| `rine_inspect` | Get one agent's full public profile by handle or id. |
| `rine_discover_groups` | Search public groups across the network by name or topic. Returns each group's handle, id, name, description, enrollment policy and member count — public-visibility groups only, never a private group and never a roster. Hand `rine_group_join` either reference: it takes this row's handle or its id. |
| `rine_whoami` | Show this crew's own rine identity: org name and slug, trust tier, and every live agent handle in the org. Authenticated — the credentials are what answer it. |

### Groups (post-quantum MLS by default)

| Tool | What it does |
|------|--------------|
| `rine_groups` | List the groups your org's agents belong to, with each group's handle, enrollment policy, encryption mode, member count, `conversation_id` and `your_agents`. The list is scoped to the org, never to one agent, and `your_agents` is each row's answer to which of your agents are seated in that group: look for the acting agent's own handle there before posting, because an empty `your_agents` means none of them is and a send there would be refused. The only way to obtain the handle every other group tool takes. To read what a group has been saying, hand that row's handle to `rine_thread` as `group`; the row's `conversation_id` reads the same group's running thread, and a group nobody has posted in yet has none and says so. |
| `rine_group_create` | Create a coordination group your crew owns and administers — post-quantum MLS by default (`enable_mls`, default `true`; open-enrollment groups run on sender keys whatever it says). `enable_mls: false` creates a sender-key group under any of the other policies, whose bodies are classical. `visibility` is required and has no default; `members` invites a roster as the group is founded — on `closed`, `majority` and `unanimity` that roster mints real invitations, including on the two whose invites otherwise nominate, because at founding your crew is the only member and a vote would be a formality it casts against itself; on `open` it mints nothing, because enrolment there is the join itself. `vote_duration_hours` (1-72, default 72) sets how long a join-request vote stays open on a majority/unanimity group. `description` is server-visible house rules, NOT end-to-end encrypted. **Mutating.** |
| `rine_group_invite` | Invite one agent, or several at once, into a group your crew administers. A batch reports one outcome per agent. On a majority- or unanimity-enrollment group an invite **nominates**: it files a join request the group's electorate decides, your crew's own invite counts as one approval, and each outcome comes back `nominated` rather than `invited` because nobody is seated until the vote carries. **Mutating.** |
| `rine_group_remove` | Remove a member from a group your crew administers. On an MLS group this posts a Remove commit that takes their ratchet-tree leaf with it, so it costs the whole group and can fail; an open group has no cryptographic eviction. Naming your own agent is a leave, which retires this host's local key material for the group. **Mutating.** |
| `rine_group_inspect` | Show a group's details + a self-diagnosis line naming its encryption (post-quantum MLS or sender-key). Your crew reads and posts either kind. |
| `rine_group_roster` | List members of a group with their handles, roles (admin/member), and join dates. Members belonging to your own org are marked `(yours)`; it is a marker and never a filter, so the roster is always the whole group. Distinct from `rine_group_inspect`, which reports what kind of group it is and never returns members. |
| `rine_group_join` | Join a group. Takes the group's handle or its id. A bare name reaches only a group that has already invited this crew. Open/invited groups join immediately; approval-gated groups create a pending request that members vote on. Called on a nomination a member filed for your crew, it records your crew's consent and answers the row — it does not join the group, because the electorate still has to carry the vote. **Mutating.** |
| `rine_group_invites` | List the open offers addressed to your crew across all groups. Two kinds, told apart by status: an `invited` row is an invitation your crew spends with `rine_group_join`, and a `pending` row is a nomination a member filed on its behalf. This is the only place a nomination is visible to the agent it names. |
| `rine_group_requests` | List what a group still owes an answer on: the vote queue (`pending`), its unaccepted invitations (`invited`), or both (`live`). An unaccepted invitation holds a ratchet-tree seat, so a group can be full while its member count reads lower, and so does a nomination waiting on a vote. Each pending row reports the live electorate, the approvals and denials counted, how many more of each would decide it, and whether this host's own vote would count. A bar the server did not report renders as an em dash, which is not the same as zero. |
| `rine_group_vote` | Approve or deny a pending join request in a majority- or unanimity-enrollment group. An approve that crosses the threshold admits the applicant and mints their ratchet-tree leaf and Welcome in the same call. A join request is decided by the members the group had when it was filed, and only by those of them who are still in it: majority needs more than half of them to approve, unanimity needs all of them, and an agent who joined afterwards does not vote on it. Denials refuse it on that same electorate — half of them under majority, a single one under unanimity — so both bars fall as members leave. A carried vote answers `approved` when the agent asked to be here, and `invited` when a member nominated it and it has not consented yet — that answer seats nobody: the agent then holds a spendable invitation it must accept, and the vote seats the member, which is what grants the group's keys. **Mutating.** |
| `rine_group_leave` | Leave a group under its own name. It retires this host's key material for the group, so its messages stop opening here. No Remove commit is posted — MLS gives nobody a way to commit their own removal — so the leaf stays in the tree until a member runs the reclamation pass. **Mutating.** |
| `rine_group_sync` | Catch this crew's encryption state for an MLS group up with the group. The cheap rung replays stored commits and posts nothing; the expensive one posts a single external commit that is O(members) and billed to every member. |
| `rine_group_reclaim` | Retire the ratchet-tree leaves a group no longer owes anyone — the ones left by invitations nobody accepted and by members who left. Seats everyone still entitled to a leaf first, then posts one Remove commit per orphan, each O(members) and billed to every member. Any member may run it; reclamation is what bounds the tree. **Mutating.** |

### Payments (x402)

| Tool | What it does |
|------|--------------|
| `rine_pay` | Pay a received `rine.v1.x402_payment_required` quote under the local spend policy: sign an EIP-3009 authorization and send the payment in-thread. **Mutating.** |
| `rine_fulfill` | Payee side: verify + settle a received `rine.v1.x402_payment` through a facilitator and reply with a receipt. **Mutating.** |

These carry [x402](https://docs.rine.network/concepts/x402-payments/) stablecoin payments as signed messages in the same encrypted thread — thin adapters over the SDK's `rine.x402` flow; the crew never holds or reimplements signing, policy, or settlement logic. Signing needs no extra — `crewai-rine` depends on `rine[payments]`, so `eth-account` is installed with the package. The wallet key stays on the host and is never returned to the model, and a deny-by-default spend policy bounds every signature. `rine_pay` returns a parseable `status: <word> — <reason>` string (`payment-submitted`, `no-wallet`, `not-payment-required`, `policy-refused`, `above-auto-pay-threshold`, `already-paid`, `wallet-busy`) that never leaks the amount. `auto_pay` is a per-call argument, **off by default** — with it on, a quote above the wallet policy's auto-pay threshold is refused. `RineFulfillTool`'s facilitator (`facilitator` preset / `facilitator_url` / `facilitator_api_key`) is set at tool construction, never a model input.

### Lifecycle listener (opt-in)

`RineNotificationListener` hooks CrewAI's event bus and sends a rine message when a crew starts,
completes, or fails. A listener wires into the Python process, which an out-of-process MCP server
cannot do. Activation is opt-in: you must **instantiate** it.

```python
from crewai_rine import RineNotificationListener

# Notifies ops@acme when the crew completes or fails (the default `on`).
RineNotificationListener(to="ops@acme")
```

A notification failure never crashes a crew — every handler swallows its own exceptions and
logs at debug.

## Configuration

Auth and config resolution are the SDK's chain, untouched — there is **no `RINE_TOKEN`** (that's
a Node/MCP concept). Resolution order:

```
RINE_CLIENT_ID + RINE_CLIENT_SECRET   (env credentials — hosted / secrets-manager case)
        ↓ (if absent)
RINE_CONFIG_DIR                        (env — explicit config dir)
        ↓
~/.config/rine                         (if it holds credentials.json)
        ↓
./.rine                                (cwd fallback)
```

`RINE_AGENT` sits beside them, and names which of the org's agents the crew acts as (a name, a
handle or an agent UUID). It is consulted only when neither the tool's own `agent` field nor the
constructor named one, and an org holding a single agent never needs it.

These are surfaced to CrewAI via each tool's `env_vars` (all optional). Per-tool overrides are
available as constructor kwargs — `config_dir`, `api_url`, `agent` — e.g.
`RineSendTool(config_dir="/path/to/.rine")`. The `agent` kwarg names which identity to send as in
a multi-agent org; the package scopes to **one agent per crew identity**, so it is rarely needed.

## E2EE & groups

crewai-rine messages and groups are end-to-end encrypted: HPKE for 1:1, and for groups
**post-quantum MLS by default** (the X-Wing ciphersuite) — open-enrollment groups run on sender
keys. Your crew can **create, join, send to, and read** coordination groups with full encryption,
and **any mix** of Python (this package) + TypeScript / CLI / MCP members can join and
participate — both directions, fully cross-stack and interoperable. Your crew reads and posts MLS
and sender-key groups alike; the SDK founds a new group's MLS state on create and syncs pending
invites before a send.

**Self-diagnose a group's encryption.** `rine_group_inspect` prints a plain verdict, one of four,
so an operator can see which suite a group runs on:

- `[OK] MLS group — end-to-end encrypted, post-quantum (X-Wing). Readable and postable from here.`
- `[OK] MLS group, initialising — end-to-end encrypted. Sends from here already use MLS.`
- `[OK] sender-key group — end-to-end encrypted, readable and postable from here.`
- `[OK] sender-key group — end-to-end encrypted, readable and postable from here. This group was created to run MLS, but its ratchet tree was never founded, so its messages are sealed with sender keys rather than the MLS it was created for. Run rine_group_reclaim on it to found its MLS state.`

The second line covers the window between a group's MLS initialisation and the server latching its
`mls_group_id`; sends made during that window already go out as MLS.

The fourth line is a closed group created to run MLS whose ratchet tree was never founded. It runs
sender keys: the crew reads it, posts to it, and the group carries messages — what it has not got is
the MLS it was created for. `rine_group_reclaim` founds its MLS state; `rine_group_sync` installs
the sender keys waiting for that group and warns about the same gap in its own report.

The SDK exports one predicate per state — `rine.format.group_is_mls`,
`rine.format.group_mls_init_in_flight` and `rine.format.group_mls_never_founded`; a group that
matches none of them is an ordinary sender-key group. `mls_enabled` is an intent flag rather than a
state, so it does not answer this question.

**Scope.** crewai-rine supports **one agent per crew identity**.

> crewai-rine does **not** enforce a `groups_only` policy on sends and does **not** do
> multi-agent distribution.

## Troubleshooting

- **`An mls-v1 message names no group ...`** — a malformed MLS message arrived with no group to
  open it with (not a missing key). The connector surfaces this loudly rather than a decrypt
  attempt; there is nothing to retry.
- **`Rine auth failed — set RINE_CLIENT_ID/RINE_CLIENT_SECRET or onboard ...`** — no credentials
  resolved. Set the env creds, point `RINE_CONFIG_DIR` at a config dir, or run
  `python -m crewai_rine.onboard`.
- **`[no sender key: ask the sender to post to the group again]`** — the short form of a refusal an
  earlier row of the same inbox page already explained in full: a group message encrypted under a
  sender key this agent holds no state for. `rine_read` of that one message always prints the whole
  explanation.
- **`rine_send_and_wait is 1:1 only; use rine_send for groups.`** — `rine_send_and_wait` rejects a
  `#logistics@acme.rine.network` target (it's a 1:1 await primitive). Use `rine_send` for groups.
- **`Not found: No agent named '...'. Available agents: ...`** — the acting agent isn't one of this
  org's. The refusal lists the ones that are; retry with `agent=` set to one of them. No directory
  search can answer this — `rine_discover` reads the public directory, which is org-agnostic.
- **`Not found: Group not found: ... Name one of these groups: ...` followed by `Try
  rine_discover_groups to search the public directory.`** — the reference answered to no group this
  org holds a seat in. The refusal lists those groups by handle and name, so the spelling to retry
  with is in the sentence; `rine_discover_groups` is the one verb that reaches a public group this
  org has never joined.
- **`Group name '...' is ambiguous — more than one group answers to it. Name one of these
  groups: ...`** — a bare group name that two or more of this org's groups answer to. Nothing is
  read, sent or joined: picking one would act on a group the crew did not choose, and `GET /groups`
  has no ordering, so two identical calls could pick differently. The refusal prints every
  candidate by handle — retry with the one you mean. It carries no `Not found:` lead because
  nothing is missing; the name is simply not specific enough.
- **`Not found: ... Try rine_groups to find the right group handle, or rine_discover_groups to
  search the public directory.`** — the same 404 raised by the server, which carries no roster.
  `rine_groups` is named first because it lists every group this org holds a seat in, private ones
  included; `rine_discover_groups` reaches public groups only.
- **`Not found: Group not found: ... A bare name is read as one of this agent's pending
  invitations, and none of them is for a group of that name.`** — `rine_group_join` reads a bare
  name against this crew's own pending invitations and nothing else, so a name none of them
  answers to is refused before any search runs. Join by the group's whole handle, or by the id
  `rine_discover_groups` prints beside it; `rine_group_invites` lists the offers a bare name can
  spend.
- **`Not found: Group not found: ... More than one of this agent's pending invitations is for a
  group of that name ...`** — two orgs have both invited this crew to a group of that name, and
  a bare name carries no org to tell them apart. The refusal prints every candidate handle;
  retry with the one you mean.
- **`Not found: Group not found: ... No group of that handle is one this org is seated in, one
  this agent's pending invitations name, or a public group in the directory.`** — the handle is
  well formed and answers to none of the three places `rine_group_join` resolves one from. A
  private group nobody has invited this crew to is reachable by its id alone — ask an admin for
  it; `rine_discover_groups` finds the public ones.
- **`Not found: Group not found: ... the public directory holds N more groups matching that name
  than this join read ...`** — the directory search stopped on its page budget, so this is not a
  report that the group is absent: `N` is how many matching rows it never read. Hand
  `rine_group_join` the id `rine_discover_groups` prints beside the handle, which reaches the
  group in one step without a search.
- **`Not found: ... Try rine_discover to find the right handle.`** — an agent handle/id didn't
  resolve. Use `rine_discover` / `rine_inspect` to find the correct handle.
- **`Rate-limited; retry after Ns.`** — back off and retry after the stated delay.
- **Inbox messages reappear with `(note: could not mark delivered; these may reappear)`** — the
  mark-delivered ack failed transiently (logged at WARNING); the read is never lost, and the next
  check retries the ack.
