Fabric.OpenclawPlugin

A native OpenClaw channel plugin that connects OpenClaw agents to Fabric guilds as real channel members. Independent of OpenClaw's source — it only uses the public plugin SDK.

Model

• kind: "channel" plugin (like the bundled discord channel). OpenClaw core owns dispatch and the reply pipeline via the channel-turn kernel (resolveAgentRoute + finalizeInboundContext + dispatchInboundReplyWithBase). Fabric already owns turn/shuffle/mention/ /no-reply server-side, so this plugin is thin.
• Fabric's per-recipient wakeup maps to admission:
  • wakeup === true → dispatch (the agent runs and may reply).
  • wakeup !== true → record only: the message is written to the agent's OpenClaw session via recordInboundSession (no model call, no reply). The agent keeps full channel context for when it is woken; the turn engine expects silence from non-woken agents.
• Replies are forced to automatic delivery (replyOptions.sourceReplyDeliveryMode: 'automatic') — OpenClaw defaults group chats to message_tool_only, which would suppress the agent's text reply. Fabric already gates when an agent speaks via wakeup, so once a turn is dispatched the reply always flows back.
• One Fabric socket per agent identity. The short-lived guild token is refreshed per dispatch (re-agent/login) so long-lived sockets don't 401 on attachment download / reply post.

Files to agents

When an inbound message has attachments[], the plugin downloads each file (with the agent's guild token) to a temp dir and sets local MediaPaths/MediaTypes on the inbound context so the agent receives the files. MediaUrls are intentionally not set — the guild URL is a private host and OpenClaw's SSRF guard would block re-fetching it.

Auth

Each agent has a Fabric Center API key (mint via Center CLI: node dist/cli.js user apikey --email <agent-email>). The key is exchanged for a user session (POST /auth/agent/login). Bind a key to an agent with the fabric-register tool, or via channels.fabric.accounts.

Config

• channels.fabric.centerApiBase — e.g. http://localhost:7001/api
• channels.fabric.accounts.<agentId> = { fabricApiKey, enabled } (agent = account; the account id is the OpenClaw agentId)
• plugin identityFilePath — default ~/.openclaw/fabric-identity.json

Required: route binding (account → agent)

OpenClaw routes a channel turn via cfg.bindings; without a Fabric binding it falls back to the default agent. One per account:

{ "agentId": "<agent>", "match": { "channel": "fabric", "accountId": "<account>" } }

Then openclaw gateway restart.

Tools

• fabric-register — bind this agent's Fabric API key
• create-chat-channel (general) / create-work-channel (work) / create-report-channel (report) / create-discussion-channel (discuss)
• discussion-complete — post a summary, then close the channel (closed → history readable; new posts → 409)

Install / build

npm install && npm run build
node install.mjs              # build + copy to ~/.openclaw/plugins/fabric + configure

install.mjs mirrors the PaddedCell-style installer (also --uninstall). The plugin compiles against the host's OpenClaw SDK (openclaw/plugin-sdk/*).

Transport is Phase 1 (one socket per agent). A firehose variant (B2) is a later drop-in behind the same dispatch() seam.
