name: claw-lark-patches description: Re-apply custom patches to claw-lark plugin dist files after updates. Use when claw-lark plugin is updated/reinstalled and custom behaviors (requireMention filtering, reply_in_thread, thread-based replies) stop working. Also use when debugging Lark message routing issues.

claw-lark Patches

claw-lark is a compiled plugin — we patch dist files directly. Every plugin update wipes these patches. This skill documents exactly what to change and provides an auto-apply script.

Quick Apply

bash scripts/apply-patches.sh

Then restart gateway: openclaw gateway restart

Patches Overview

Four files are patched: 1. channel.js — messaging.targetResolver (target ID recognition) + outbound account resolution 2. monitor.js — requireMention filtering + reply-in-thread for deliver callback 3. provider.js — reply-in-thread for sendTextMessage 4. send.js — reply-in-thread for SDK reply calls

Patch Details

0. channel.js — Target Resolution + Account Resolution (2026-02-22)

Problem 1: message(send, lark, "oc_xxx") returns "Unknown target" because claw-lark has no messaging.targetResolver.looksLikeId. The core doesn't recognize oc_/ou_/on_ as valid IDs and falls through to directory lookup which fails.

Fix: Add messaging property to larkPlugin export:

Import looksLikeLarkId, normalizeLarkTarget from ./utils.js

Add messaging.targetResolver.looksLikeId using existing looksLikeLarkId()

Add messaging.normalizeTarget using existing normalizeLarkTarget()

Problem 2: outbound.sendText gets { cfg, to, accountId } from core but expects { account, recipientId }. The account object is undefined → "Cannot read properties of undefined (reading 'appId')".

Fix: All 5 outbound methods (sendText, sendMedia, downloadMedia, addReaction, removeReaction) add:

const account = args.account ?? resolveAccount(args.cfg, args.accountId ?? "default");
const recipientId = args.recipientId ?? args.to;

1. monitor.js — requireMention Filter

Location: routeMessage() function, after parseMessage(event) and the log line.

What: In group chats, skip messages that don't @mention our bot.

Key facts:

event.message is the correct path (NOT event.event.message)

Lark webhook message.mentions contains mention data with id.open_id

Bot open_id: set via BOT_OPEN_ID env var when running apply-patches.sh

All bots lack user_id (empty string) — cannot use !user_id to detect "is it me"

@_user_N text placeholders appear for ALL @'d bots, not just ours — don't use regex match

Fallback: if mentions array empty, check parsed.text.includes("@" + BOT_NAME) (set via BOT_NAME env var)

2. monitor.js — Reply in Thread (deliver callback)

Location: Inside dispatchReplyWithBufferedBlockDispatcher deliver callback.

What:

Set replyToId = payload.replyToId || parsed.threadId || parsed.messageId (always have a value)

Use client.im.message.reply() with reply_in_thread: true instead of client.im.message.create() with root_id

Key facts:

root_id on create only associates with existing thread, does NOT create new thread

reply_in_thread: true on reply API creates a new thread

Works in both p2p and group chats

3. provider.js — sendTextMessage Thread Reply

Location: sendTextMessage() function.

What: When threadId is provided, use client.im.message.reply() instead of client.im.message.create().

4. send.js — reply_in_thread on SDK Reply

Location: sendMessageLark() and sendCardLark() reply branches.

What: Add reply_in_thread: true to data object in client.im.message.reply() calls.

Verification

After applying patches and restarting gateway: 1. Send a group message WITHOUT @bot → should be silently ignored 2. Send a group message WITH @bot → should reply in thread 3. Send a DM → should reply in thread 4. @ another bot → should be silently ignored
