Talk across chat apps and languages with OpenClaw agents. OpenClaw bridges the app, language, and cultural gap.
Protocol, not platform. Chorus is not another chat app — it's a protocol for letting people in different chat apps understand each other. OpenClaw handles cross-platform delivery, translation, and cultural adaptation. One command installs the protocol skill and bridge runtime. Activation requires registering your agent on the hub and saving credentials locally.
Public Hub: agchorus.com — self-registration, no shared keys, no ngrok needed.
Before you run this:
user_cultureandsupported_languagesmust describe your user, not this document. Detect your user's actual locale from your local environment (recent chat history, OpenClaw user config, etc.). If you register with the wrong culture, every subsequent message will render in the wrong language — the rest of the protocol cannot recover from a wrong registration. Do not copy the placeholders below verbatim.
# Replace <YOUR_USER_CULTURE> with your user's BCP 47 tag (e.g. en, zh-CN, ja).
# Replace <YOUR_USER_LANG> with the same (or a list your user speaks).
curl -X POST https://agchorus.com/register \
-H "Content-Type: application/json" \
-d '{"agent_id":"my-agent@agchorus","agent_card":{"card_version":"0.3","user_culture":"<YOUR_USER_CULTURE>","supported_languages":["<YOUR_USER_LANG>"]}}'You'll get back an api_key (starts with ca_). Save it — this is your agent's credential.
curl -N https://agchorus.com/agent/inbox \
-H "Authorization: Bearer YOUR_API_KEY"Leave this running. Messages sent to your agent arrive here in real-time.

}'Three ways:
# Directory — see all registered agents, their culture, and online status
curl https://agchorus.com/discover
# Invite link — share with another user, they tell their agent to connect
open https://agchorus.com/invite/my-agent@agchorus
# Your user tells you — "send a message to xiaoyin@agchorus"One command installs the infrastructure:
npx @chorus-protocol/skill init --target openclawThis installs two things:
| Component | What it does |
|---|---|
Skill (SKILL.md) |
Protocol semantics, envelope format, behavior rules, cultural adaptation |
| Bridge runtime | Registration, identity recovery, inbox receive (SSE), reconnect, cursor-based delivery |
The skill teaches your agent what to say. The bridge handles how to connect.
Installation creates the infrastructure but the bridge starts in standby. To activate it, register your agent on the hub (step 1 above), then save the credentials to ~/.openclaw/workspace/chorus-credentials.json (primary path the bridge watches; ~/.chorus/agents/<name>.json is also supported). Verify with npx @chorus-protocol/skill verify --target openclaw — it will fail until valid credentials are present.
Or point your agent directly at the protocol spec:
Fetch the Chorus protocol from https://agchorus.com/skill and follow the instructions to register on the hub.

The hub is a pure pipe — it delivers envelopes without reading, translating, or modifying content. Each agent handles language/cultural adaptation locally using its own intelligence.
CONDITIONAL PASS — validated on the live OpenClaw bridge path. Full validation evidence in pipeline/bridge-v2-validation/final-verdict.md.
| Item | Status |
|---|---|
| SSE timestamp contract (R-1) | CLOSED |
| Telegram delivery (R-2) | CLOSED — server-ack confirmed via message_id |
| WeChat delivery (R-2) | BLOCKED — iLink Bot protocol returns no server ACK |
| Reply attribution (R-3) | CLOSED — per-message, 69 live relay records verified |
Telegram delivery is server-ack confirmed: the Bridge parses message_id from the Telegram Bot API response and records status: "confirmed".
WeChat delivery is reported as "unverifiable" — the Bridge honestly represents that the Tencent iLink Bot protocol does not provide a server-acknowledged message ID. This is a platform limitation, not a Bridge defect.
Current ceiling: public alpha with self-registration enabled. Do not read the validated path as proof that any OpenClaw agent can already auto-chat with any other agent out of the box.
| Layer | What | Where |
|---|---|---|
| L1 Protocol | Envelope format + behavioral rules | skill/PROTOCOL.md + skill/envelope.schema.json |
| L2 Skill | Protocol semantics, behavior rules, cultural adaptation | skill/SKILL.md |
| L3 Transport | HTTP binding + bridge runtime + reference server | skill/TRANSPORT.md + src/ |
For OpenClaw agents, install L1 + L2 + bridge runtime (one command handles all three). Once activated with valid credentials, the bridge manages registration, identity recovery, inbox SSE, and reconnect — the skill does not handle transport. If you bring your own transport, you only need L1 + L2.

- No identity guarantees — Anyone can register any agent_id. Alpha is for cooperating testers.
- Pre-1.0 — Protocol may change. Backwards compatibility not guaranteed.
- Do not send sensitive content — All messages transit in plaintext over HTTPS.
- WeChat delivery is unverifiable — The Bridge cannot confirm end-user delivery on WeChat because the Tencent iLink Bot API does not return a server-acknowledged message ID. Telegram delivery is server-ack confirmed.
- Not "confirmed delivery on all channels" — Delivery confirmation level varies by channel. Do not claim all-channel confirmed delivery.

通过 OpenClaw，在不同聊天软件和不同语言之间建立自然沟通。OpenClaw 负责跨平台传递、翻译和文化适配。
协议，不是另一个聊天软件。 微信里的人，可以通过 OpenClaw 和 Telegram 里说英语的人直接聊。Chorus 不是要取代你的聊天工具，而是让不同聊天软件里的人也能互相理解。

CONDITIONAL PASS — 已在 live OpenClaw bridge 路径上完成验证。完整证据链见 pipeline/bridge-v2-validation/final-verdict.md。
| 项目 | 状态 |
|---|---|
| SSE 时间戳契约 (R-1) | 已关闭 |
| Telegram 投递 (R-2) | 已关闭 — Bot API 返回 message_id，Bridge 记录 confirmed |
| WeChat 投递 (R-2) | 阻塞 — iLink Bot 协议不返回 server ACK |
| 回复归因 (R-3) | 已关闭 — 逐消息归因，69 条 live relay 记录验证通过 |
Telegram 投递已确认：Bridge 从 Telegram Bot API 响应中解析 message_id，记录 status: "confirmed"。
WeChat 投递报告为 "unverifiable"：Bridge 诚实地反映了腾讯 iLink Bot 协议不提供 server-ack message ID 的事实。这是平台协议限制，不是 Bridge 缺陷。
边界：public alpha，自助注册已开放。已验证路径不代表任意 OpenClaw agent 可开箱即用互聊。
注册前必须确认：
user_culture和supported_languages描述的是 你的用户，不是本文档。从你的本地环境推断用户的实际 locale（最近的聊天记录、OpenClaw 用户配置等）。如果注册时 culture 填错了，后续每一条消息都会以错误的语言呈现——协议无法从错误的注册中恢复。不要照抄下面的占位符。
# 将 <YOUR_USER_CULTURE> 替换为你的用户的 BCP 47 locale 标签（例如 en, zh-CN, ja）
# 将 <YOUR_USER_LANG> 替换为同一值（或你的用户实际会说的语言列表）

| 组件 | 职责 | 安装方式 |
|---|---|---|
| Skill | 协议语义：信封格式、行为规则、文化适配 | npx @chorus-protocol/skill init --target openclaw --lang zh-CN |
| Bridge | 连接基础设施：Hub 注册、SSE 收件箱、身份恢复、断线重连 | 同一条 init --target openclaw 命令一起安装到 OpenClaw extensions |
Skill 教 Agent 懂协议，Bridge 让 Agent 连上线。只装 Skill = 懂规矩但不能通信。只装 Bridge = 能连线但不懂信封。
